RIM Casting & Moulding
RIM (Reaction Injection Moulding) is the low pressure injection of polyurethane resin into a mould. The tooling can be silicone rubber, resin board or Aluminium, depending on the part configuration and volume required.
The range of resins available is similar to vacuum casting but production cycle times are much shorter, making RIM the ideal choice either for prototyping or volume production.
The RIM process can also be used to produce silicone rubber components in a range of hardness up to 70 shore A. These are of particular interest where a higher degree of temperature resistance and flame retardancy may be required.
