The Secret is in the compound...
Over the years rubber components have become more and more popular, with a large assortment of different compounds all with different properties.
Polymax are not only able to manufacture in the standard compounds, we are also able to tailor make compounds to meet your specification.
Rubber Compression Moulding
The compression moulding process consists of a piece of uncured rubber placed between two halves of a heated mould. This mould is then closed in a specially designed press which produces around 14MPa worth of pressure. The uncured rubber is then forced into the exact shape of the mould. The curing process is achieved by gaining heat from the two moulds by conduction. After sufficient time the moulds are opened and the cured part is removed. The compression moulding process is relatively simple and commonly used for small quantity production.
Rubber Injection Moulding
Like the name suggest this processes is created by the injection of rubber into as mould. The mould is heated and the compound is injected into this. This method is commonly used to produce high-precision parts in moderate quantities, without high tooling costs.
Polymax normally work to ISO 3302 1995 (BS3734) Class M2 tolerances, although tighter tolerances can be discussed. The tighter the tolerances the more costly the tooling.
