Rubber Injection Moulding 2

Rubber Injection Moulding

Rubber injection moulding is a large part of what we do at Camberley Rubber Mouldings – exactly as you might expect from one of the premier bespoke rubber moulding manufacturers in the UK.

Camberley Rubber Mouldings have more than 50 years of bespoke rubber moulding experience and during that time have moulded thousands of types of rubber products. Furthermore, as our case studies demonstrate, our expert team of injection moulding specialists undoubtedly provide a superior service for all our customers in the UK and Overseas.

Injection moulding is the choice for many multi-cavity, high volume orders that demand high-quality repeatable production. Once the initial tooling cost is accounted for, the component cost is less when compared to Compression or Transfer moulding, often offering big savings over larger volume runs.

I have been dealing with Camberley Rubber for the last 7 years and in this time we have enjoyed a problem free and very pleasant relationship with all contact staff at Camberley. We have often been in serious need of assistance, eg. our customer would experience a problem and Camberley will always go the extra mile to help solve our customer issues.In the last 7 years, we have not experienced a single late delivery or a non-conformance! Camberley is an outstanding supplier to our company and if we as a company presented “Supplier of the year” awards, Camberley would win year on year as they are by far the best supplier that we deal with.

The chosen compound is continuously fed into the injection press in a strip form after which then enters into the screw and barrel. The screw and barrel then heats up the compound ready for injection into a runner system that feeds the cavities in the tool. As the compound is partially heated during this process, the curing time is faster than that of the Compression or Transfer Methods, offering a shorter cycle time.

On completion of the predetermined cure time the press automatically opens, the parts are then removed from the tool, the press automatically closes and the cycle is repeated. As these presses are computer programmed, the future production of the same parts is consistently repeatable.

There are so many factors that contribute to the success of rubber injection moulding, from the design of a product through to selecting or developing the best rubber compound for the application, programming the machinery to developing the optimum operating conditions. All these variables will be taken into consideration by our qualified engineers when planning any project.

Rubber Injection Moulding process

Step One

A piece of uncured rubber strip is passed into the feed point and down into the screw.

Step Two

The screw moves and heats the polymer and pushes it down in to the mould.

Step Three

The tool is opened, the moulding removed from cavity and the injection pip removed to the required finish. The process is ready to be repeated.
