Understanding the Silicone Injection Molding Process: Key Steps for Custom Solutions

Understanding the Silicone Injection Molding Process: Key Steps for Custom Solutions

Oct 28,2024

1. Material Preparation

The process begins with the preparation of liquid silicone rubber (LSR), a key component due to its flexibility, heat resistance, and durability. The LSR is a two-part mixture (A and B components), typically stored separately to avoid premature curing. These parts are mixed in precise ratios, ensuring that the silicone reaches the ideal consistency for injection molding.

2. Mold Design and Tooling

The next step involves designing the mold. Silicone injection molding requires highly accurate molds, which are typically made from steel or aluminum, depending on the project specifications. At Siliconeplus, our expert engineering team designs and creates molds that match the client's exact specifications, ensuring precision for complex shapes and customized features.

3. Injection and Curing

Once the mold is ready, the silicone injection molding process begins. The mixed silicone is injected into the mold cavities at high pressure using advanced injection molding machines. During this step, the mold is heated, which initiates the curing process—a critical phase where the silicone solidifies and takes on the desired shape.

4. Cooling and Demolding

After the silicone has fully cured, the mold is allowed to cool. This step ensures the material sets properly before being removed from the mold. Demolding is performed carefully to avoid damaging the finished product, ensuring high precision and a smooth surface finish.

5. Post-Processing

Once the parts are demolded, they may undergo post-processing such as trimming, surface treatments, or additional assembly if needed. Siliconeplus ensures that every product meets the highest quality standards, whether it's combining silicone with metal, plastic, or FPC for unique applications.
