silicone overmolding electronics is a technique where a layer of silicone rubber is molded over a substrate to provide protection. The silicone can be molded into various shapes and thicknesses, and is commonly used to produce protective covers for electronic components.
There are three primary kinds of silicone for overmolding electronics: two-shot overmolding, insert overmolding, and multi-shot overmolding.
1. Two-shot overmolding is the most commonly used type. First, a rigid plastic substrate is molded, and then a soft silicone is molded onto or around the substrate.
2. Insert overmolding is similar to two-shot overmolding, but insert overmolding involves placing a pre-formed insert into the mold before injection molding. The insert can be made from any material, but is typically made from metal or plastic.
3. Multi-shot overmolding is a method of overmolding that involves the use of three or more different types of silicone.
