Overmoulding, the process of adding an extra layer of resin to an existing moulded part, is used for many reasons, most commonly to add grip, for aesthetics and can be used when wanting two different materials without having to deal with screws, glue and assembly. This insight video looks at things to consider when choosing a material for your overmoulded part, discussing important facts such as, thickness, melting temperatures and chemical/mechanical bonds.

One of the great plus points of 3D printing is that you can design pretty much any shape or geometry that you want, and Nylon is a great general-purpose material to use. But there are some key considerations to keep in mind when designing nylon parts to make sure you get the parts you want.

Ejector pins are utterly vital to the process of creating injection moulded parts. If all goes well they barely leave a mark, but sometimes this is not the case. In this video we talk about how design and position can minimise this, considering shape and specific qualities of the part.

Polyjet is a 3D printing technology that offers great accuracy and uniquely allows you to alter the part’s material properties in different places on the build. For the right part or prototype Polyjet is a great option, but understanding the capabilities and limitations is key.

This video will tackle the tricky topic of cooling rates in injection moulded parts. Looking in detail at important considerations when designing your part such as; avoiding narrow gaps leading to higher pressure, temperature uniformity, higher tolerances, multiple gates and upping cooling rates.
