Reaction Injection Molding (RIM) quick details:
Reaction Injection Molding is a low pressure, low temperature
process used to mold many types of plastic parts. This process is
typically used for the medical equipments/devices, industrial and
automotive interiors and exteriors. RIM is often utilized for the molding of strong, lightweight parts
that are easily painted. The rigid materials used by KAIAO come
with a UL94V-0 rating PP & ABS for flammability.
The RIM molding material utilized by KAIAO is a two-component
system which consists of polyol and isocyanate liquids that are
mixed at a high pressure and then metered into the closed tool at a
low pressure. The material then expands to fill the tool and is
ejected in about 5 minutes. After mixing the two components PU, inject the mixture into rapid
prototyping mold under room temperature and low pressure. After
polymerization, cross-linkage, and curing chemical reactions,
physical part will be formed.
Reaction Injection Molding Advantages:
-Large Parts, able to fill molds for very large parts, max.2000mm X 1200mm X 1000mm;
-Encapsulation of Inserts - Inserts of many types can be placed
into a mold prior to injection of the RIM material;
-Thick and Thin Walls, flexibility to design parts with significant
wall thickness variations;
-Class-A Surfaces by post finishing process;
-Lower Cost Tooling Options than traditional tooling.
Automotive Reaction Injection Molding Applications:
-Automotive Bezels;
-Automotive bumpers;
-Automotive Multiple part complete plastic enclosures;
-Automotive plastic car doors;
-Automotive plastic front and rear housings.
