Silicone Injection Molding Process Step by Step
Dec 13,2020 | Industry News

Successful customized silicone injection molding requires process management guided by professional knowledge and precise technology.

 

The preparation work in the early stage is very important, which requires the injection machine engineers and professional technicians to invest a lot of time.

Let's see the Silicone Injection Molding Machine:

Silicone injection molding steps:

  • Silicone pellets are fed from a hopper into the barrel.
  • The screw rotates to move the pellet forward, friction and the action of the heater make the particles melt.
  • After the tool cavity is filled, the silicone must be allowed to cool.
  • While the injection-molded silicone part is cooling within the tool, the screw retracts and reloads with melt in preparation for the next injection.
  • The molded material reaches its ideal, the tool opens automatically and the part is pushed out.The silicone injection molding process is completed.

 

The silicone injection molding process is a multi-step process. Each step affects the performance and results of the silicone parts.

 

Silicone Injection Molding Applications

Silicone has good biological inertia and biocompatibility. So silicone injection molding products are also used in many fields.

 

  1. Industrial parts
  2. Medical industry
  3. Maternal and infant industry
  4. Military / Aviation
