SilKeypad

At Silkeypad, we understand the critical importance of precision and efficiency in Liquid Silicone Rubber (LSR) injection molding. When it comes to LSR molding, one key decision manufacturers face is whether to use a hot runner or cold runner system. Each of these systems has distinct advantages, depending on the product’s design, volume requirements, and cost considerations. In this post, we’ll dive deep into both systems, comparing their functions, benefits, and the types of products they’re best suited for.

Cold Runner System in LSR Injection Molding

Typically, the cold runner system is the more commonly used approach in LSR injection molding, especially for applications where precision is critical and material waste must be minimized. In a cold runner system, the silicone material remains at a cooler temperature until it’s injected into the heated cavities of the mold. This allows manufacturers to ensure that the silicone remains in a fluid state until it’s ready for curing, avoiding unnecessary material waste during the molding process.

One of the biggest benefits of using a cold runner system is its ability to significantly reduce material waste. This is particularly advantageous when working with expensive LSR materials. By keeping the material in the cold runner until the injection process begins, excess material is minimized, helping to conserve costs.

However, the cold runner system does come with a trade-off. Due to the need for components like needle valves and shut-off valves to control the flow of liquid silicone and ensure precision, the system’s initial cost can be quite high. The needle valve system is designed to regulate the flow of silicone into the mold cavities, ensuring consistent material flow and high product quality. While these systems provide more control and higher precision, they do increase the overall cost of production.

At Silkeypad, we specialize in offering high-precision LSR molding solutions, tailored to meet your product’s unique specifications. Whether you require a cold runner system for highly detailed components or are looking to explore cost-effective options, we are here to provide expert guidance and ensure optimal results for your manufacturing needs.

Hot Runner System in LSR Injection Molding

In contrast to the cold runner system, the hot runner system operates without the need for needle valves and shut-off valves. This system relies on a heated runner to maintain the silicone material in a molten state, allowing for direct injection into the cavities without the need for temperature-controlled runners.

The hot runner system is typically favored for low-volume production runs, or in situations where precision and strict dimensional tolerances are not as critical. For example, products like LSR baby nipples or other silicone components used in consumer goods often rely on the hot runner system. These products generally do not require the same level of precision as medical or industrial components, making the hot runner system a more cost-effective choice.

The primary advantage of the hot runner system is its ability to reduce the overall mold cost, particularly in applications where high precision is not a necessity. However, it does not offer the same level of material control or precision as the cold runner system, which can result in slight variations in product consistency, especially in more complex designs.

For many manufacturers, the hot runner system provides a good balance between cost and performance. It’s an excellent solution for high-volume, less-precision-driven applications, offering an affordable and efficient approach to LSR molding. At Silkeypad, we can help you determine which system best suits your production needs, whether it’s high-volume manufacturing with less stringent tolerance or low-volume precision parts.

Advantages of the Cold Runner System

1. Higher Precision

One of the key benefits of the cold runner system is its ability to provide highly precise molded products. This is due to the controlled injection process facilitated by the needle valve system, which ensures consistent material flow into the cavities. As a result, products made with cold runner molds tend to have tighter tolerances and more accurate dimensions, which is essential in industries like medical devices, electronics, and automotive components.

2. Material Savings

Unlike the hot runner system, which can result in material waste, the cold runner system helps minimize waste by only injecting the exact amount of silicone needed for each part. This is especially important when working with expensive materials, as it helps reduce production costs while ensuring optimal material usage.

3. Improved Product Quality

The precision control offered by the cold runner system ensures that liquid silicone flows consistently into the cavities, helping to produce parts with consistent quality and minimal defects. This makes the cold runner system ideal for manufacturing high-quality LSR products that require uniformity and reliability.

4. Reduced Deburring and Post-Processing

In cold runner systems, the mold typically produces finished products without the need for additional trimming of gates or rubber flashings, which are common in hot runner molds. This reduction in post-processing steps can lead to faster turnaround times and lower labor costs, further enhancing production efficiency.

5. Automation Integration

Many manufacturers are now combining cold runner systems with automation technology to increase production efficiency. Automation can streamline the molding process by handling repetitive tasks such as loading, unloading, and trimming, allowing for more consistent and high-quality production at a larger scale.

6. Enhanced Mold Technology

Cold runner systems serve as the foundation for many advanced molding technologies, which continue to evolve and improve. By investing in cold runner technology, manufacturers can expand their capabilities and stay competitive in industries that demand precision and performance.

Disadvantages of the Cold Runner System

Despite its many advantages, the cold runner system does come with one primary disadvantage: higher mold costs. The inclusion of needle valves and shut-off valves, which are essential for controlling the flow of silicone, adds significant expense to the overall mold. These components can cost several hundred to thousands of dollars each, depending on the number required for the mold.

For molds with multiple cavities, the cost can quickly add up, which makes the cold runner system less ideal for high-volume production of lower-cost, less-precision products. In these cases, manufacturers may opt for the hot runner system to keep costs down.

At Silkeypad, we understand the complexities of selecting the right molding system for your product. Whether you’re looking to achieve high precision with the cold runner system or exploring the cost-effective advantages of the hot runner system, we are dedicated to providing tailored solutions that meet your manufacturing needs.

Conclusion

In conclusion, both cold runner and hot runner systems offer distinct benefits in LSR injection molding, and the right choice depends on the product’s requirements and production volume.

Liquid Silicone Rubber (LSR) has increasingly gained popularity across a wide range of industries, thanks to its non-toxic, transparent, and tear-resistant properties. It has become a preferred material for applications in sectors such as baby products, kitchenware, medical devices, automotive, and bathroom fixtures. As a company committed to providing high-quality silicone products, Silkeypad understands the importance of precision in the manufacturing process, especially when it comes to customization. One common question we encounter in the industry is whether Shore hardness and color can be adjusted in the LSR injection molding process.

In this blog, we will explore the challenges and considerations associated with altering Shore hardness and color in LSR injection molding, and why these adjustments may not always be practical for every production scenario.

Can Shore Hardness and Color Be Adjusted in the LSR Injection Molding Process?

The short answer is yes—both Shore hardness and color can be altered in the LSR injection molding process. However, the process is not without its challenges, and there are several factors to consider before making such changes. While the potential for customization exists, it can often come at the cost of time, material waste, and additional cleaning requirements, especially when switching between different hardness levels or colors during production.

When it comes to Shore hardness, LSR material typically comes in a range of hardness levels, with Shore A hardness being the most commonly used for many applications. However, changing the Shore hardness of the material during the injection molding process is a time-consuming and inefficient task. In scenarios where small production runs are involved, testing different Shore hardness levels may not be practical due to the high amount of waste material that is generated. For example, when altering the Shore hardness, the material that is purged from the system before achieving the desired hardness can be substantial, and the cleaning process required can take up to an entire day. This makes Shore hardness changes more complicated and resource-intensive compared to other molding methods, such as compression molding, where adjustments can be made more easily.

Likewise, changing the color of the LSR during the injection molding process presents its own challenges. In compression molding, changing the color is relatively straightforward—simply adding pigment to the mix and milling the material suffices. However, in the case of LSR injection molding, the color change process is much more involved. Similar to Shore hardness changes, switching colors during injection molding requires significant time and effort, particularly in cleaning the feeding systems, nozzles, and needle valves. Ensuring that the mold produces parts with the correct color after a change involves thoroughly cleaning the system to prevent cross-contamination between different color formulations.

While both Shore hardness and color modifications are possible, it is important to understand the constraints that come with them. At Silkeypad, we are committed to delivering high-quality LSR products, but we also emphasize the need for efficient production. In most cases, altering hardness or color is not recommended for small production runs, as the material waste and extended lead times can reduce the overall efficiency of the project. For larger production volumes, however, such changes may be more feasible.

Why Is It So Difficult to Clean the Cold Runner in LSR Injection Molding?

One of the primary reasons why altering Shore hardness and color is difficult in LSR injection molding is the complexity of the process, especially when it comes to cleaning the cold runner system. Unlike compression molding, where the setup is more straightforward, LSR injection molding systems feature intricate feeding systems, nozzles, and needle valves that need to be thoroughly cleaned after each production cycle.

The cold runner system, which carries the LSR material from the injection machine to the mold, is often a source of contamination when switching between different materials or colors. Any residual silicone material left in the system can impact the quality of the next production cycle, resulting in unwanted variations in Shore hardness or color. This is why it is crucial to properly clean the entire system between different runs. Cleaning the cold runner, needle valves, and feeding systems is an extensive process that requires attention to detail and can take up to half a day to complete.

Even a small amount of leftover material can lead to issues with the final product. This is a critical factor to consider when determining whether changing Shore hardness or color is worth the effort for your specific production needs. If the system is not properly cleaned, the results can be subpar, leading to discrepancies in the final product, as seen in the following example.

Real-World Example: A Case of Improper Cleaning

To illustrate the challenges involved in LSR injection molding, let’s examine a real-world scenario that occurred at Silkeypad. One of our customers requested 10 Shore A liquid cannula samples made from medical-grade LSR. Our team used 10 Shore A material to produce the samples, but when the samples were tested, we found that their hardness was higher than expected—approximately 20 Shore A rather than 10 Shore A.

After a thorough investigation, our production team discovered that the cause of the discrepancy was an incomplete cleaning process. The previous batch of material used in the system was 30 Shore A, and despite the switch to 10 Shore A material, traces of the harder material remained in the feeding system. As a result, the new samples exhibited higher hardness than intended. This example highlights the importance of proper cleaning and how even small amounts of residual material can affect the final product. At Silkeypad, we always ensure that our cleaning processes are meticulously followed to avoid such issues and deliver products that meet the highest standards of quality.

Best Practices for Shore Hardness and Color Changes in LSR Injection Molding

While altering Shore hardness and color during LSR injection molding is possible, it is essential to approach these changes with caution. Here are a few best practices to consider:

1. Minimize Material Waste: For small production runs, it may not be worth the time and resources required to alter Shore hardness or color. If adjustments are necessary, ensure that you are working with larger production volumes to make the changes more feasible and cost-effective.
2. Implement Thorough Cleaning Procedures: To ensure that Shore hardness and color adjustments are successful, it is crucial to implement rigorous cleaning protocols. This includes purging the system of any residual material and thoroughly cleaning the feeding system, needle valves, and nozzles.
3. Plan for Extended Lead Times: When making Shore hardness or color changes, be prepared for longer lead times. The time required to clean the system, set up the new material, and test the results can add significant delays to the production process.
4. Work with Experienced Professionals: Working with an experienced silicone molding company, like Silkeypad, can help streamline the process. Our team has the expertise and equipment to handle even the most complex LSR injection molding projects, ensuring high-quality results and minimal waste.

Unmatched Quality with Liquid Silicone Rubber

Quality is the cornerstone of any successful product. If you’re seeking a material that delivers exceptional performance, LSR is the clear choice. Unlike traditional rubber or gum stock materials, liquid silicone rubber is made from two liquid components – an A and a B – with the A part containing the catalyst, typically platinum. This unique molding process is what sets LSR apart from other materials.

One of the key advantages of LSR is the “closed-loop system” it offers. From the moment the silicone is placed in the machine to the point where the finished product is molded, it is completely sealed. This ensures that there is minimal exposure to contamination, which significantly reduces the chances of defects or imperfections. The fewer hands that touch the material, the lower the risk of contamination, making it a superior option for manufacturers who want to ensure the highest quality in their end products.

Molding techniques play a crucial role in the manufacturing landscape, each offering unique characteristics and applications. In this discussion, we will delve into three prevalent methods: Liquid Injection Molding (LIM), Compression Molding, and Transfer Molding. We will highlight their respective advantages and limitations, as well as their common applications across various industries.

Liquid Injection Molding (LIM)

Liquid Injection Molding, commonly referred to as LIM, utilizes liquid silicone rubber (LSR) or similar elastomeric materials to produce a wide range of high-performance products. The method is renowned for its ability to create items that exhibit exceptional durability and flexibility. Typical applications for LIM include:

– Seals and sealing membranes

– Electrical and electronic components, including connectors and cables

– Medical devices and sterile components

– Kitchenware

– Infant care products

One of the primary advantages of LIM is its streamlined mechanical mixing process. Unlike traditional methods that may involve labor-intensive operations, LIM employs a closed-loop system that integrates a pump and mixing unit to ensure precise blending and dispensing of the liquid material into the molding press. After the curing phase, the press opens to release the finished product, which can be removed either manually or through robotic automation.

LIM stands out as a cost-effective and versatile manufacturing option, making it applicable across numerous sectors such as:

– Aerospace

– Automotive

– Electronics

– Food and beverage

– Healthcare

When executed correctly, LIM consistently yields high-quality molded components at scale. However, it is essential to assess whether silicone is the most suitable material for the intended application. For instance, silicone may react unfavorably with specific environmental conditions, such as exposure to pressurized steam at temperatures exceeding 150°C. Such conditions can compromise the integrity of the siloxane polymer, leading to deterioration in material properties.

Compression Molding

Compression Molding is a versatile technique that involves placing thermosetting resins into a heated mold cavity. Pressure is then applied to compress the material within the mold, ensuring precise part formation. Throughout this process, careful regulation of temperature and pressure is maintained, which is crucial for achieving accurate and consistent results.

This molding method is particularly advantageous for producing parts of various sizes, thicknesses, and geometrical complexities. It is well-suited for manufacturing applications that demand specific materials, the incorporation of challenging inserts, or uniquely shaped components. Industries benefiting from compression molding include:

– Automotive

– Aerospace

– Consumer products

– Medical

Key advantages of compression molding encompass:

– Adaptability to diverse compound requirements for optimal performance

– Capability to mold complex geometries

– Prototype production flexibility with material customization

– Insert and dual-material molding possibilities

Parts manufactured through compression molding can offer significant environmental resilience and high chemical resistance. Typical products produced via this method include buttons, gaskets, respirator masks, spatulas, and syringe stoppers.

While compression molding is effective for high-volume production, it generally lags behind LIM in terms of processing speed and consistency, often requiring more labor involvement. However, it does offer benefits such as faster production changeover times, potentially lower tooling costs, and reduced upfront material expenses. Given these variables, it is advisable to consult with your molding service provider to determine if compression molding aligns with your specific production requirements.

Transfer Molding

Transfer Molding shares similarities with compression molding, yet it distinguishes itself through its unique tooling and processes. In this method, material is pushed into a mold via a sprue, using a plunger rather than a screw and barrel system typical of injection molding.

Both transfer and injection molding are efficient techniques for producing high-quality, durable products at scale. However, injection molding generally achieves faster cycle times, making it preferable for certain applications.

Transfer molding offers several notable benefits, including:

– Reduced flash formation at mold parting lines

– Quicker setup times

– Lower tooling expenses

– Enhanced design flexibility and complexity potential

This method is applicable across various industrial applications, providing manufacturers with a reliable means of producing high-quality components.

The end result is often seen in dual-colored keys or keyboards with varying hardness levels, enhancing both the appearance and usability of the final product.

Rubber and Plastic Overmolding

In the rubber and plastic overmolding approach, plastic components are molded first before being combined with rubber parts. This integration is achieved through techniques such as liquid silicone injection molding. Given that most plastics cannot endure high temperatures, low-temperature curing methods are employed to prevent deformation of the plastic parts during the overmolding process. A common application of this technique is seen in liquid silicone baby bottles that feature a durable PPSU ring.

Rubber and Metal Overmolding

This type, also referred to as insert molding, integrates metal components into the rubber structure. Unlike plastic, metal parts can withstand higher curing temperatures, removing the risk of melting during the overmolding process. To ensure a robust bond between rubber and metal, metal components are typically primed before being inserted into the rubber mold cavities. This ensures a strong connection and enhances the durability of the final product.

Detailed Steps in the Keyboard Overmolding Process

The keyboard overmolding process is considerably more intricate compared to standard rubber keypad production. The complexity arises from the need for clear parting lines between colors and the requirement for precise positioning of components.

1. Independent Molding of Colorful Keys: Different shapes and sizes of silicone keys are compression molded separately. These keys can be created in various Pantone or RAL colors and may have different durometer levels to achieve the desired tactile feedback.
2. Positioning Keys: Once the individual keys are ready, they are carefully placed into corresponding key position tools, which facilitate accurate alignment within the mold.
3. Incorporating Carbon Pills: For keyboards that require conductivity, carbon pills are positioned in the mold cavities prior to the placement of the rubber keys. This step is critical for ensuring proper functionality in electronic applications.
4. Securing Keys: The multi-color key position tools are used to firmly secure all rubber keys into their designated cavities within the rubber keyboard mold. This precision is essential for achieving the desired final appearance and functionality.
5. Molding Setup: After the keys are positioned, rubber raw material is introduced into the keyboard mold. The mold is then closed and clamped, initiating the curing process.
6. Curing Process: The overmolding temperature for rubber buttons typically hovers around 170°C. The curing time and temperature must be tailored to the thickness and geometry of the keyboard. For thicker designs, extended curing times are required to ensure complete material integrity and avoid issues with uncured sections.
7. Finalizing the Product: Once the rubber keyboard has fully cured, it is removed from the mold. The process can then be repeated for additional production runs.

Advantages of Keyboard Overmolding

The advantages of keyboard overmolding are manifold. Key benefits include:

– Enhanced Flexibility: Overmolding adds flexibility to rigid components, improving overall usability and comfort for end-users.

– Aesthetic Appeal: The process allows for the creation of visually striking rubber parts that can be tailored to specific design requirements.

The Process of Silicone Keyboard Prototyping:

Creating a silicone keyboard prototype involves a meticulous and multi-step process that requires attention to detail and precision. From the initial design stages to final production, each step plays a vital role in ensuring the functionality and durability of your keyboard prototype.

The first step in the process is the design phase. This involves conceptualizing the keyboard’s layout and functionality, taking into account factors such as key size, spacing, and overall ergonomics. Designers use specialized software to create a digital representation of the keyboard, which can be adjusted and modified before moving on to the next stage.

Once the design is complete, the next step is to create a physical prototype. This is usually done using a 3D printer, which can accurately replicate the digital design. The prototype is then tested functionally and ergonomically, and any necessary adjustments are made before moving on to the next stage.

After the physical prototype is approved, the next step is to create a mold for the silicone rubber. This involves using prototypes to create a negative impression, which is then used to produce the final silicone rubber keyboard. The mold is carefully crafted to ensure it captures all the intricate details of the prototype, resulting in a precise and accurate reproduction.

Once the mold is ready, pour the silicone rubber and let it cure. This process requires precision and expertise to ensure that the silicone rubber sets properly and maintains its intended shape and function. Once the silicone rubber has cured, the keyboard is carefully removed from the mold and given a final inspection to ensure it meets the required specifications.

Creating a silicone keyboard prototype is a complex and involved process that requires expertise and attention to detail every step of the way. But,it is an interesting process,right? From the initial design stages to final production, each stage plays a vital role in ensuring the functionality and durability of your keyboard prototype. By completing this process with precision and care, designers can create high-quality silicone keyboard prototypes that meet the needs of their target users.

For more professional applications, custom molded keyboards offer a high degree of customization in shape, layout and tactile feedback. These prototypes are customized to meet the unique requirements of specific electronic devices, ensuring a perfect fit and seamless integration.

In summary, silicone rubber keyboard prototypes play a vital role in the development of electronic devices, enabling design improvements, material testing, and customization.
