At CB Frost, we offer custom moulded rubber components in a comprehensive range of materials, such as Neoprene, Silicone, Nitrile, EPDM and Viton, which can be tailored to our customer’s needs. We offer rubbers which are flame retardant, chemical resistant, military grade, WRAS, FDA, and to British standard – e.g. Natural rubber to BS1154, Neoprene to BS2752 and Nitrile to BS2751.
We also offer our custom moulded components in Rail specific fire-retardant grades that are compliant to rail industry standards EN45545-2, BS6853 and LUL (London Underground) safety standards. For further details on our materials etc, please visit the rail sector section of our website.
Tooling is manufactured to suit the application, from single for prototype/small batch production, to multicavity tools designed for long running schedules.
Reverse Engineering & Material Selection
If you are looking to replicate an existing part, CB Frost can work with you to reverse engineer, offering like for like or in alternative materials. We understand material selection can be critical for the working applications and our technical support team will be able to help.
Overseas Sourcing of Rubber Moulded Components
In some instances, it is worth considering overseas production, this could be due to cost or quantity involved. CB Frost have a reliable and trusted partnerships with several suppliers built up over a 10-year period and manage the process from start to finish.

How does compression moulding work?
The compression moulding manufacturing process involves placing the raw compound into the moulding cavities of a pre-heated tool (see image below). The desired shape and size of the component will affect the shape of the tool cavity, as well as how much moulding material will be required. In order to ensure that the correct amount of material is used, it is weighed before being placed into the cavities of the moulding tool. Once the correct quantities of the raw material have been placed in the tool cavities, the mould will be closed, and the compression moulding process can take place (see image below).
Heat and pressure are applied to the moulding, allowing the raw materials to form the desired shape. The mould remains closed until the compression mouldings have cured (set). The amount of time needed to complete the moulding process depends on the type of material being used, the temperature that it is moulded at, and the size of the component.
At CB Frost we have vast experience in creating mouldings to a set specification for a range of industries. Our team are able to advise customers as to the best type of material to utilise for a particular project, and we aim to meet fast lead times at all times.
