Rubber and silicone moulding

To mould rubber products into the desired shape and give them the required properties, Pro-Flex Rubber combines specific elastomers in moulds inserted into hydraulic heat presses of various size. This process is referred to as compression moulding.

Rubber injection moulding

Pro-Flex Rubber uses rubber injection moulding to manufacture parts with various mechanical functions and properties. The rubber compound is injected into a heated barrel and funnelled into a mould cavity where it is cured and hardened in the desired shape.

This manufacturing process use two different types of injection moulding: injection in either closed moulds or open moulds. Closed moulds are used to manufacture parts such as plumbing seals and gaskets, and open moulds are used to manufacture junctions by overmoulding one or several elements together to create window corner joints; for railway cars, for example.

Pro-Flex Rubber also offers rubber and silicone injection splicing solutions to manufacture finished products.

Rubber compression moulding

Rubber compression moulding is an efficient and economical manufacturing method to give the desired shape to elastomer products, particularly with low production volume. The Pro-Flex Rubber team has the necessary expertise to mould or overmould rubber and silicone of all colors.

Rubber transfer moulding

Rubber transfer moulding is a process in which rubber material is loaded in a heated transfer pot that uses compression to transfer it into mould cavities. Pressure forces the rubber to take the mould’s shape.
