Reaction Injection Molding Large Plastic Car Parts Cheap And Rapid
Mold Good Quality Fast Delivery
Reaction Injection Molding (RIM, also named Low-Pressure Injection
Molding) is an ideal process to low volume manufacturing the large
plastic parts quickly and economically. Firstly, the liquid
bi-component polyurethanes are injected into a mixer at certain
amount ratio and meanwhile mixed well by the mixer, then the
mixture is injected into the tooling cavity quickly at room
temperature and low pressure to form the parts.
Advantages of RIM Parts:
Thick and Various wall thickness for one part
Excellent mechanical properties
High flexibility, strength and durability
Good chemical resistance
Great impact resistance
Excellent dimensional stability
The high pressures used cause the plastic to conform to the mold’s
shape, thereby generating the part. Like metal die casting, custom
plastic injection molding typically produces components that
require little or no additional work. Reaction Injection Molding
(RIM) is a specialized subset of the injection molding technique
that chemically bonds two or more plastics into a polymer before
they are introduced into the mold.
Customer was an automotive design and engineering company in USA,
wanted to test impact and high temperature resistance of this
bumper by low volume rapid prototypes. Though customer was new to
our RIM technique, found it was a proper and economical solution
for this project.
RIM Parts Design Considerations:
When designing parts for RIM production, it's important to consider
factors such as size, structure, wall thickness, draft angles, and
gating. RIM parts can be designed with complex geometries and
intricate details, but it's important to ensure that the part
design is manufacturable and the tooling favors the design.
We are respected in RIM industry in China, the RIM service we send
out to global market are quick, economical and quality that are
proven by the customers used our service, especially from
automobile field. We look forward to doing more and better by our
continuously improving RIM expertise and experience.
Industry Applications:
RIM is commonly used in the low volume manufacturing or prototyping
of automotive, aerospace, medical devices, and consumer goods
parts. Such as automotive bumpers & grills, body panels, interior
components, aerospace ducting, large enclosures, big housings and
medical covering shells.
The maximum weight by one shot of injection molding was 35
kilograms, so our RIM process was available for molding the vast
majority of parts. Being different to injection molding by steel mold, our RIM had
simple demolding system, and worked fine for insert molding and
overmolding.
Due to the low injection molding temperatures and pressures, RIM is
well-suited for molding large parts with variable wall thickness
and smooth surface finishes. We can also benefit from its
relatively high turnover rate, which makes it proficient in
handling low to middle volume production projects. In addition, RIM
parts have high tensile strength, heat resistance, and good
resistance to corrosive acids or solvents. However, prolonged
exposure to sunlight can degrade polymer-based parts.
We are the RIM expert in China to provide customers quality RIM
material, cheap and rapid tooling, fast delivery, especially for
automobile field. The trimmed, deburred, sandblasted and sanded parts. Customer was
satisfied with the bumper's flexibility after impact resistance
testing.
How does HONKIA compare to other suppliers on price?
Compared to other Chinese suppliers, we choose not to compete on price but to offer
the high level of quality, rapid response, and professional results. That’s why some customers cooperate with us for many years, compared with the price, they need a reliable partner to avoid
serious losses caused by annoying after-sales service or even the trouble of finding no one.
What if I am not completely satisfied with the parts I receive?
HONKIA will free remake or amend the returned parts that you are not
completely satisfied, or refund the full arrived payment, though
this is rarely happened in the past. Any disputes based on a subjective or unilateral determination shall be discussed and negotiated to reach a reasonable result. Our continuing business relies on earning your confidence in our
ability to meet and exceed the reasonable expectations.
