What Is Silicone Overmolding Process-the Metal And Silicone Combin Overmolding Pencil Bag Can Show It?
What is Silicone overmolding?
Silicone Overmolding is a process where a single part is created using two or more different materials in combination. Typically the first material, sometimes referred to as the substrate, is partially or fully covered by subsequent materials (overmold materials) during the manufacturing process.
What is the Overmolding Material and how this material overmolded?
- Silicone Over Silicone-First a silicone substrate is molded. Then another silicone is molded onto or around the substrate. The silicone could differ in color and/or hardness.
- Silicone Over Plastic – First a rigid plastic substrate is molded. Then a soft Silicone is molded onto or around the substrate. This is often used to give a soft grip area to a rigid part.
- Silicone Over Metal-First a metal substrate is machined, cast or formed. Then, the substrate is inserted into an silicone compression molding tool and the silicone is molded onto or around the metal. This is often used to capture metal components in a silicone part.That is today process what we would like to show.
A few things to note:
There are limitations and compatibility issues to consider between different materials.
You are not limited to only two materials. We have seen some products with three different materials on one part in order to achieve color breaks and grip surfaces. Here is a simple example with a product you will be intimately familiar with: scissors.
