Reaction Injection Molding

Reaction Injection Molding(RIM)

AN-PROTOTYPE Corporation provides you with low-pressure perfusion technology, which is a new one and can be applied to rapid casting production. This technology enjoys its advantages of high-efficiency, short production phase, simple process and low cost, and can be applied to the mass production of covering parts with simple structures and large products with thick walls or nonuniform walls. When large-size products are to be produced with their number from 100 to 5000+, AN-PROTOTYPE Corporation suggests that you may adopt the method of low-pressure perfusion, which can ensure the accuracy of the dimension of the bulk-production items.

The Reaction Injection Molding process includes infusing the mixed two-component polyurethane material into the mould to let the material form a molded article through chemical or physical processes, including aggregation, cross bonding, solidification, etc. quick quotes and advice in 24 Hours or Less.



RIM Technical Parameters

There are various kinds of selectable moulds.
