Reaction Injection Moulding (RIM/PUR)
Reaction Injection Moulding (RIM/PUR) is the ideal technique for small to medium-sized series of complex products with a slightly greater wall thickness. The large variation in PUR-compositions allows for the production of soft to hard products.
How does Reaction Injection Moulding (RIM/PUR) work?
Depending on the desired hardness the PUR-components (polyol and isocyanate) are injected in different quantities into the mould through a pump.
The mould is filled for 60 to 80% with this mixture. Because of the chemical reaction the product froths and fills the mould completely.
After curing, we remove the product from the mould and finish it (deburring, lacquering,...).
