The Sherborne Rubber Company Ltd has been a bespoke moulder of rubber since 1937.
We are ISO 9001:2008 accredited and able to produce a wide variety of rubber and rubber-related products.
We use Compression, Transfer and Injection moulding techniques as appropriate to produce custom items of any size and style.
By compounding our own rubber in-house, we are able to shorten lead times and create custom characteristics and hardnesses to meet your design requirements.
Our versatile plant can ensure that we can meet your specification requirements, with our presses ranging from 30 tonne to 450 tonne.
With compression moulding, a pre-formed rubber blank is placed inside a cavity of a mould and then compressed, spreading the rubber all around the mould.
Transfer moulding involves a billet of rubber being placed into a transfer box, normally above the mould cavities, and then being forced into the mould with a plunger.
Injection moulding is used in high-volume production and involves rubber being injected directly into the mould cavities.
IN-HOUSE CRYOGENIC BARRELLING
Cryogenic Barrelling is an efficient way of processing large volumes of product, removing the flashing from moulded products. The products are frozen with liquid nitrogen and then tumbled around in a barrel, which removes the flash from all of the outer edges.
As well as using the cryogenic barrelling equipment for our own products, we are able to tumble customers’ products too. Any rubber items, from tiny washers to large bonded products can be processed in large batches, quickly and efficiently, leaving a clean, professional finish.
We combine this process with a hand-finishing service and rigorous quality testing, to ensure that all products are delivered to meet your specifications and high standards.
