The definition of RIM:
RIM (Reaction Injection Molding), is a Rapid Tooling process where parts are made from mixing and injecting PU materials into a mold and cured through a process of polymerization (molecular cross-linking) in a low pressure / room temperature environment.
Our RIM machine
Three Mold : Epoxy resin mold(life>100shots) ABS plastic mold ( life>300shots) Aluminum mold ( life>1000shots )
Injection material: Dual injection process PU
Physical properties:PP/ABS, Part is durable, high impact, high degree of fit ,loading and unloading properties.
General curing time:15-30 minutes/piece, Part takes 2-4 houres to cure under 80c condition after mold release.
standard accuracy: 0.2mm/100mm
Thickness of mold part: max 100mm
Advantages of RIM process
Compared to Plastic Injection Molding, RIM (Reaction Injection Molding) is a more simple and convenient process with a shorter production cycle.
Compared to Vacuum Casting, RIM offers a higher level of automation and efficiency.
Compared to Thermo-Forming and Board Bonding, RIM is a more flexible design option.
RIM parts can be designed with elaborate surface details and Class A surfaces, with integrated structures and different wall thicknesses, and with machining stability and accuracy.
