Silicone Overmolding Process
Silicone Overmolding Process: Enhancing Product Durability and Comfort
The silicone overmolding process is an advanced composite molding technique that encapsulates soft, durable silicone material over plastic or metal hardware components, achieving multifunctional product integration. This method is widely used in silicone product manufacturing, such as seals, grips, and medical accessories, ensuring core parts receive additional protection and tactile optimization.
Process Overview
First, mold design and preparation: Custom dual-layer molds are created based on product specifications to precisely embed plastic or metal hardware into the silicone layer. Next, substrate pretreatment: Plastic parts undergo surface activation for better adhesion, while metal hardware requires electroplating or coating to prevent corrosion. Finally, high-temperature silicone injection: Liquid silicone is injected into the mold and cured at 150-200°C for 10-30 minutes, forming a uniform overmold layer.
Technical Advantages
This process highlights silicone's waterproof, shock-absorbing, and biocompatible properties, perfectly combining with plastic's lightweight nature or metal's strength. The finished surface is smooth and flexible, extending service life by over 20%, suitable for electronics, automotive, and daily consumer goods. Through precise control, it ensures zero bubbles and no delamination, elevating product quality and market competitiveness.
