Regrind Plastic Injection Moulding

Stephens Plastic Mouldings Limited is one of the best plastic injection moulding companies in the UK today. We have been in the business since 2011, but before that, we were also known as Stephen Gaskets. Therefore, our years of experience under our belt has enabled us to hone and develop an effective technique. Especially, when it comes to our primary expertise, plastic injection moulding. Out of many plastic materials we use here for injection moulding, one in particular is Regrind.

Regrind Plastic Injection Moulding Manufacturer


Injection moulding is a manufacturing process of injecting a raw material to mould to create an entirely different thing. It is a typical process for glass, elastomers, confections, and thermoplastic. This is the same idea for the Regrind plastic injection moulding process.

Regrind Injection Moulding

Affordable Resin Material

The idea behind Regrind plastic injection moulding is similar to recycling. It is excellent because it helps the environment. However, using it requires a lot of careful consideration because they have already been broken down, unlike the typical virgin material. But, what’s great about them is that they are more affordable compared to other types of resin material.

Regrind refers to the plastic material generated during the actual injection moulding process, especially during the flash and trim processes. Some moulding equipment produces more regrind compared to others.

When regrind is used in the moulding process, the viscosity will be affected depending on how much regrind is in the blend in the feedstock. This is  because Regrind materials have more viscosity than virgin materials. This is why to create a similar flow characteristic between the virgin and Regrind material, increasing the melt temperature during the process is needed for the Regrind.

Regrind And Virgin Material

There can be a lot of issues when combining Regrind and virgin material during plastic injection moulding. However, several methods could make it better. For example, rather than using a ratio of regrind and virgin materials, you can instead use 100% virgin material and feed the 100% regrind later on to the machine. This solves the issue in the difference of melt point between the two materials.

Using Regrind injection moulding can be tricky. But, the years of experience and the recent acquisition of state of the art machinery, Stephen Plastic Moulding Ltd has is one of the best injection mould service providers to handle Regrind injection moulding. As a client, you will surely appreciate their detailed step by step process which begins with the design stage, development of prototypes, choosing of materials and the actual injection moulding process.

Dealing With Regrind Material

Moreover, dealing with Regrind material that has already undergone mechanical and thermal stress, it is an excellent process to know its heat history so that you can pinpoint its chemical and physical degradation.

This also helps in identifying the melt temperature applicable and how much virgin to regrind material you need.
