The manufacturing process of silicone products mainly includes the following steps:If you want to make a big difference in the market, custom rubber seals It is necessary to intensify the upgrading of products on the original basis in order to meet the consumption needs of consumers. https://www.ascendseal.com
1. Raw Material Preparation
Silicone Material: Selection of suitable solid or liquid silicone rubber.
Additives: Addition of pigments, vulcanizing agents, plasticizers, etc., as needed to enhance performance or appearance.
2. Mixing
Uniformly mix the silicone and additives in a mixer to ensure consistent material properties.
3. Molding
Compression Molding: Place the mixed silicone into a mold and shape it by heating and pressing.
Injection Molding: Liquid silicone is injected into the mold using an injection machine, suitable for complex shapes.
Extrusion Molding: Silicone is extruded into strips or tubes through an extruder and then cut to the required length.
Calendering: The silicone is calendered into sheets for making films or sheets.
4. Vulcanization
Vulcanization is carried out under high temperature and pressure to cross-link and cure the silicone, enhancing its elasticity and durability.
