What are the processing techniques for silicone products and what are the differences in the techniques?
The processing technology of silicone products mainly includes the following:
Compression molding:
Process description: Place silicone material into a mold and cure it into shape through heating and pressure. Application: Widely used in manufacturing seals, gaskets, buttons, etc. Features: Simple process, low cost, suitable for large-scale production.
Injection molding:
Process description: After heating and melting the silicone particles, they are injected into the mold and cooled to form. Application: Suitable for manufacturing silicone products with complex shapes. Features: High production efficiency, suitable for large-scale production, but high equipment cost.
Extrusion molding:
Process description: Silicone material is extruded into shape through an extruder, commonly used for manufacturing tubular or strip-shaped products. Application: such as silicone tubing, silicone strips, etc. Features: High production efficiency, suitable for continuous production, but the product shape is relatively simple.
Rolling forming:
Process description: The silicone material is rolled into thin sheets or films through a rolling machine. Application: such as silicone film, silicone film, etc. Features: Suitable for manufacturing thin silicone products, but with low production efficiency.
Adhesive molding:
Process description: Wrap silicone material onto other substrates (such as metal or plastic) and shape them through vulcanization. Applications: such as silicone hardware packaging, silicone plastic packaging, etc. Features: Provides additional protection and improves hand feel, but the process is complex and the cost is high.
3D printing:
Process description: Use 3D printing technology to print silicone material layer by layer. Application: Suitable for manufacturing silicone products with complex shapes. Features: High flexibility, suitable for small batch production, but high equipment and material costs.
Differences in craftsmanship
Compression molding: using pre formed silicone blocks. Injection molding: using silicone particles. Extrusion molding: using silicone strips or particles. Rolling forming: using silicone blocks. Encapsulation molding: using liquid silicone gel. 3D printing: using silicone printing materials.
