Camberley Rubber Mouldings offers a comprehensive range of bespoke rubber production tailored to your specific technical and commercial needs. As one of the leading rubber suppliers in the UK we have developed innovative ‘rubber engineering’ solutions for even the most challenging applications.
Often seen as the most basic method of rubber moulding, compression mould tooling is generally lower in cost than injection mould tooling. Therefore, it is common for customers with lower quantity requirements to use this option for low volume products.
Rubber compression moulding requires a carefully measured amount of uncured rubber to be loaded into the bottom section of the preheated moulding tool. The two halves of the tool are brought together, forcing the rubber material to conform to the shape of the tool cavity. The material is compressed and heated over a pre-determined time, during which the material cures (or vulcanises) and solidifies into the desired shape. The two halves of the tool are then opened and the newly created rubber part is removed.
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.
Camberley Rubber are an excellent supplier and have continued to meet our expectations and demand for a number of years. Their delivery performance is consistently 100% on time in full, and their customer service team are always quick and happy to help with any queries or issues.
Our previous suppliers weren’t able to provide the reliability of production, cleanliness & quality we required but CRM quickly grasped the issues & worked hard to meet our needs.
Due to the fact that the compression moulding tool is open at the start of the process, compression moulding will tend to have more ‘flash’. This is where the tool split lines occur. It is generally trimmed after the compression moulding process has been completed.
Please refer to step 3 shown below as an example.
Depending on the application, compression moulding may be the best option for your requirements and remains an integral part of the rubber moulding solutions we offer at Camberley Rubber Mouldings.
A piece (approximately 110% of the finished part weight) of cold, uncured rubber compound is placed into the heated mould.
The mould is closed between the heated platens of the press under hydraulic pressure and heated for a pre-determined time to ensure the rubber completely cures.
The press opens, the tool is pulled forward and the mould is removed; the excess rubber (flash) may then be trimmed to the required finish. The process is then ready to be repeated.
