In Pursuit Of The Perfect Injection Moulded Part – Flow Lines

It is very easy to make expensive errors when it comes to injection moulding. Quality issues in injection-moulded products can range from minor surface defects to more serious problems that can affect the safety, performance and function of the product. They can be caused by problems related to the moulding process, material use, tooling design or a combination of all three.

In this series of posts, we will look at a number of issues that can affect the quality of the end product – and some of the common remedies.

A Plastic Stepping Stone?

A new opportunity presented itself here at Patterson & Rothwell and we were quick to see the potential for manufacturing a new product for a number of existing customers.

To solve many issues with a complex moulded part the team here at P&R were able to utilise a 6 axis and a 3 axis robot to work in harmony with each other to complete 4 operations.

This procedure was completed entirely in-house.  Follow the link for a short video clip of the operation. Continue reading
