Rubber Mouldings

At CB Frost, we are able to offer a comprehensive range of bespoke rubber mouldings which can be tailored to your specific technical and commercial needs.

We supply compression mouldings for a number of different industries throughout the world, utilising general purpose commercial grade materials such as Neoprene, Natural, Silicone and EPDM rubber. Also; our moulded products can be produced in Rail specific fire-retardant grades that are compliant to rail industry standards BS6853:1999, EN45545-2, NFF-16-101 and the LUL (London Underground) safety standards. For more information on these material grades please visit our Rail Sector section of the website.

Rubber mouldings are commonly used for the following purposes:

All of our moulded rubber components are matched to the customer’s requirements and are manufactured using the compression moulding process.  This form of moulding is advantageous for moulding large and somewhat intricate parts, whilst creating very little waste material.  It is also one of the lowest costing methods of moulding rubber.

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 is applied to the moulding, to allow 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.  For further information, please contact our team on 0121 773 8494.
