Silicone products encapsulation process?

Silicone products encapsulation process, silicone products encapsulation process is a common processing method, widely used in all kinds of products.

1. What is the coating process?
The rubber coating process, also known as rubber coating or injection coating, is a process that wraps rubber or other elastomer materials on the surface of metal or other hard materials. This process can make the product have good wear resistance, impact resistance and sealing.

Preliminary preparation
Before starting the coating process, the silica gel raw material needs to be thoroughly mixed to ensure that it has good fluidity and plasticity. At the same time, the mold is checked to ensure that its surface is smooth and free of scratches and dirt.

Mold positioning
The mold made of metal or other hard materials is placed on the injection molding machine and fixed by a positioning device. Ensure the accuracy and stability of the mold to ensure the quality of the coating.

Silicone injection
The mixed silica gel raw material is injected into the mold, and the silicone is fully filled in all corners of the mold through pressure. During the injection process, it is necessary to control the injection speed and pressure of silicone to avoid the generation of bubbles and depressions.

Silicone vulcanization
After the silicone injection is completed, the mold is sent to the vulcanization oven for vulcanization. During the vulcanization process, silica gel molecules will cross-link to make silica gel have good elasticity and strength.

demould
After curing, remove the mold from the oven and let it cool to room temperature before stripping. During the demoulding process, it is necessary to ensure that there is no adhesion between the silicone products and the mold to avoid damaging the product.

Postprocessing
After stripping, the silicone products are trimmed, polished and other post-treatment to make its surface smooth and burr free.

Inspection and packing
The finished silicone products are inspected to ensure that they meet the standard requirements. Then it is packed and ready to be shipped.
