Insert and Overmoulding

Protolabs’ Insight podcast series

Our Insight podcast series is aimed to help you design better parts for digital manufacturing.

We will regularly share with you podcasts packed with useful tips that will hopefully save you some time and money, from Q&A sessions to design tips.

In this episode, we discuss design considerations for injection moulded parts, with a specific focus on overmoulding and insert moulding.

The topics we will be talking through today are:

• Overmoulding: process, method, material selection, factors to consider, chemical and mechanical bonding
• Insert moulding: process and method
• Why use overmoulding and insert moulding?
