One mold. Two materials. Zero compromises. Multi-shot molding is changing the way automotive parts are made, and it’s not just about efficiency. It’s about precision, performance, and smarter design.

Molding plastic over another plastic or incorporating a preformed part like a metal insert or sensitive electronic component demands more than just standard equipment, it requires advanced machinery and a highly skilled operator.

When executed correctly, the results speak for themselves. 💪

Often called multi-shot or multi-component molding, this sophisticated technique refers to the process of molding two or more materials within a single injection molding machine, during one continuous cycle.

In multi-shot molding, a single machine injects plastic into a mold, then rotates or repositions the tool so a second injection (using a different plastic material) can be applied from another nozzle, creating a fully integrated final part.

Multi-component molding, sometimes referred to as over-molding, follows a similar sequence but typically involves molding plastic over a non-plastic part, such as metal or electronics, effectively “sandwiching” the insert within the finished component.

Why are they so widely adopted? The benefits are clear:

✔️ Lower production costs (thanks to single-machine operation)

✔️ Elimination of many secondary processes

✔️ Faster cycle times

✔️ Superior product quality

✔️ Reduced assembly needs, all achieved in a single, efficient process

These methods are essential to modern automotive manufacturing, and they’re part of the daily production toolkit at leading European supplier NS-K.
