Manufacturing Process for POS Terminal Silicone Rubber Keypad:

The production of POS Terminal Silicone Rubber Keypads involves a precise and multi-step compression molding process to ensure high quality and durability. Here’s an overview of the process:

1.Material Preparation:

– High-quality silicone rubber is selected and mixed with curing agents and pigments to achieve the desired properties such as flexibility, durability, and color.

2.Mold Preparation:

– Precision molds, typically made of metal, are designed with cavities that match the shape and layout of the keypad, including any necessary space for conductive elements.

3.Compression Molding:

– The prepared silicone material is placed into the mold cavities. The mold is then closed, and heat and pressure are applied. The combination of heat softens the silicone, allowing it to flow and conform to the mold’s intricate details, while pressure ensures uniform distribution of the material.

4.Curing:

– The mold remains closed under pressure as the silicone undergoes curing, a process where it chemically cross-links to form a solid rubber. This step is crucial for achieving the desired hardness and resilience of the keypad.

5.De-molding and Finishing:

– Once cured, the mold is opened, and the newly formed silicone rubber keypad is removed. Any excess material is trimmed, and the keypads undergo quality inspections.

6.Conductive Printing:

– For keypads that require conductive properties, conductive inks are printed on specific areas to ensure functionality in electronic circuits.

7.Surface Coating:

– Depending on the requirements, surface coatings such as PU or epoxy may be applied to enhance durability and provide a desired tactile feel.

8.Final Inspection:

– Each keypad undergoes thorough quality checks to ensure it meets the required standards before being packaged for shipment.
