What is 2K Injection Molding?

2K (Two-Component) Injection Molding is an advanced manufacturing process that creates single plastic parts made from two different materials – all in one seamless production step.

Instead of making separate pieces and assembling them later, a special injection molding machine shoots two distinct plastics into a single mold, one after the other or sometimes simultaneously. The materials bond together chemically or mechanically inside the mold as they cool.

Why use it?

2K molding lets you combine materials with different properties right where you need them in a part. Think of:

·A soft, comfortable grip (like TPE) fused perfectly onto a rigid handle (like PP).

·A flexible seal permanently bonded to a hard plastic housing.

·Parts with multiple colors without painting.

This eliminates gluing or assembly steps, creates stronger bonds between materials, improves product feel, and can reduce overall costs. It's ideal for complex, high-quality parts needing multiple material properties.
