Injection Rubber Moulding

Maximum Durability and Versatility

Injection Rubber Moulding has an almost infinite amount of uses from making Rubber Gaiters  for joystick manufacture, where these is a need for high volume but with a high level of constancy across multiple batches, oil seals where accuracy is essential to water couplings to avoid leakage. Even buttons for breathing apparatus where precision and durability is paramount where lives are at risk. 

At SRM we have an unparalleled knowledge of injection rubber moulding and have worked across a broad range of industry sectors including: Rail, Petrochemical, Construction and Healthcare to name but a few.

All of our moulds are engineered in house by our highly skilled CNC Mould-makers, this give our customer the peace of mind that we can manage the who process from initial design through to distribution on time and on budget.

In short we INNOVATE | ENGINEER | DELIVER 

The Injection Moulding Process

The rubber injection moulding process works by significantly heating the rubber and using a very high pressure to inject the rubber compound in to the mould. From there it is injected through the runner system in the tool into the cavities of the closed hot mould. The combination of pressure, temperature and time facilitates the crosslinking of chemical bonds commonly referred to as vulcanization. Process parameters are usually programmed into the press to control temperature, volume and rate that compound is injected into the mould cavities
