1. Prepare the silicone cups of various colors designated for laser etching, along with the necessary design files in DXF format.2. Mount the corresponding fixture onto the designated worktable and secure it firmly with screws to ensure there is absolutely no shifting during the operation.3. Power on the laser etching machine and load the correct design file from the system.4. Define the required size of the laser-etched content area and align it within the machine's built-in infrared positioning zone.5. Once the necessary parameters have been configured, click "Test" to run a trial.6. Produce a sample piece and perform a First Article Inspection.7. Upon approval and sign-off of the sample, commence mass production.
1. Place the fixture in the designated position and secure it with screws to prevent shifting.2. Place the product completely inside the fixture.3. Before laser engraving, activate the infrared positioning system to align the product within the infrared working area.4. Configure the necessary parameters for the laser engraving process.5. After the initial engraving pass, wipe the product with alcohol to remove any residue or dust.6. Once the sample is completed, submit the "first piece" to the client for approval.7. Proceed with mass production following the client's approval.
Silicone keypad production typically employs traditional compression molding.Key steps in silicone keypad production:1. Pre-mixed silicone is cut to the required shape and thickness using a cutting machine. The silicone is usually specified for hardness and properties.2. The vulcanizing machine is preheated to the specified temperature, typically around 180 degrees Celsius. Corresponding pressure parameters are also set.3. After the vulcanizing machine reaches the specified temperature, a trial molding is performed. Sometimes, conductive particles are added according to specifications. These conductive particles are typically carbon, nickel, or gold particles. The trial molded sample undergoes various performance tests, such as hardness, curve analysis, and resistance.4. For low VOC requirements, a secondary vulcanization process is performed on the vulcanized product. The vulcanization time and temperature are set according to different requirements or specifications.5. Post-processing typically includes screen printing, spray coating, and laser engraving.6. After this, the product undergoes a deburring process.7. Finally, the finished product undergoes a final inspection, usually visual inspection.8. Before entering the finished product warehouse, finished products will be sampled and subjected to tests such as curve and character drop tests.
1. The operator places the keypad into the screen printing machine mold.2. A special squeegee is used to press the silicone button and mold together neatly.3. After pressing the start keypad, the squeegee slowly slides across the customized screen.4. The buttons are neatly arranged on a baking rack.5. Finally, the screen-printed silicone keypads are placed in an oven to dry.
During the hydraulic molding process, to prevent color bleed or cross-contamination between different-colored raw materials from exceeding acceptable limits, a "two-shot molding" (or secondary molding) technique is typically employed for the colored keys. This involves first hydraulically molding the colored keys using a dedicated mold; once formed and removed, they are inserted into the main mold cavity using a fixture, after which the remaining raw material is loaded for the secondary hydraulic molding process.1. Positioning the colored keys.2. Placing the conductive pellets (typically carbon or nickel pellets.3. Inserting the colored keys.4. Loading the silicone material.5. High-temperature vulcanization molding.6. Demolding the keypad.
