What can you do with this information.

Design Products

Product designer

Working as a product designer you will need to be know with this information.

There is no point really in designing a product that can not be manufactured. The content here has a strong focus on designing plastic parts for injection moulding.


Design consultant

Consulting on tool design 

Designing your parts right so there can be incorperated into a mold design is important not only in saving time but also in trouble free moulding.


Process engineer

Moulding the parts.

By understanding correct part design it will help you advise on trouble free moulding of the parts. This information will also help in troubleshooting injection moulding quality issues.
