You like and understand mechanical challenges ? and you are willing to solve them?
Then we’d like to get to know you!

What You Will Gain

This position provides the opportunity to learn the Mould Maker trade in an active injection moulding manufacturing environment.

Unlike working only in a dedicated tool shop, you will have the opportunity to see the complete process:

Mould maintenance → machine setup → mould trial → production → part inspection → troubleshooting → repair and improvement.

You will work directly with tooling, production, maintenance, engineering, and quality teams and develop a broad understanding of injection moulding and precision manufacturing.
