Automotive Reaction Injection Molding, RIM rapid small batches
manufacturing
Reaction Injection Molding (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 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.
This is a new technology implemented to fabrication of rapid
prototyping. 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. High efficiency,short
production cycle, simple process and low cost are the advantages of
low pressure injection, which is suitable for small batch
production, simple structural parts, large parts, even or uneven
wall thickness parts verification.
Advantages of RIM Molding
RIM molding allows for many distinct advantages, some of which
include:
- Large Parts - The properties of the liquid polyurethane components
enable them to fill molds for very large parts.
- Thick and Thin Walls - The RIM process offers you the flexibility
to design parts with significant wall thickness variations.
- Class-A Surfaces - The surface finish of parts molded with the RIM
process allows manufacturers to produce Class A painted parts.
- Low Cost Tooling Options - The low injection pressures of the RIM
process allow for tooling to be manufactured quicker, and at lower
cost, than tools used in traditional injection molding, or
structural foam.
