Offer high accuracy Reaction Injection Molding (RIM)




AN-PROTOTYPE Corporation provides you a low-pressure perfusion technology, which is new and can be applied to rapid casting production. This technology has advantages of high-efficiency, short production cycle, simple process and low cost, and can be used to the mass production of covering parts with simple structures and thick walls or non-uniform walls. When producing the large-size products with the production quantity from 100 to 5000+, AN-PROTOTYPE Corporation, the most professional product prototype company, 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 infuses 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.


Reaction Injection Molding Technical Parameters:

There are various kinds of selectable moulds. The selectable moulds of AN-PROTOTYPE Corporation includes ABS mould (more than 100 pieces), resin mould (more than 300 pieces) and aluminum alloy mould (more than 1000 pieces)

There are various poured materials.  AN-Prototype Corporation selects materials from French AXSON, Japanese DCPD, and domestic HD.AN-PROTOTYPE Corporation possesses rich experience in Reaction Injection Molding, and is capable of accurately controlling the pouring amount and flow velocity. We have a complete standard operation procedure, and strictly control the operational parameters of each link of the process.


The Reaction Injection Molding has high molding accuracy:

  1. Standard duplication accuracy: ±0.20 mm/100 mm;

2. The optimal thickness of the cast product is 4 to 6 mm, and the maximum thickness is 30 mm.;

3. The maximum dimension of the cast product is 2000 mm × 1200 mm × 1000 mm, with the weight of 10 kg.


The Reaction Injection Molding can be applied in the following fields:

  1. Car model and accessories

2. Housing of medical equipments
