Reaction Injection Molding RIM Housing Parts Rapid Prototype To Production Competitive Tooling Cost
Reaction Injection Molding (RIM) is an innovative manufacturing process used to produce the large and complex plastic parts with high flexibility, strength and durability. RIM involves the mixing of liquid bi-component polyurethanes in a mixer at certain amount ratio, then injecting the liquid mixture at room temperature and low pressure into mold cavity where the mixture reacts and cures into a solid part.
One advantage of RIM is its ability to produce large parts with a smooth and high-quality surface finishing, as well as the complex geometries and intricate details. Another advantage of RIM is its ability to produce parts with high strength and durability, which makes RIM parts ideal for applications that durability is a critical factor, such as industries of automotive, medical devices, aerospace, etc.
The fairly low viscosity of the bi-component polyurethanes delivers high flowability that allows for the low injection molding pressure as well as temperature, which brings the feasibility of low tooling performance. So our RIM toolings are mostly made of epoxy resin and silicone rubber (sometimes aluminum or ABS) instead of mold steel.
The extremely competitive tooling cost by our RIM process brought great advantage to low volume manufacturing this big enclosures economically and quickly. The finished enclosures had to not only perform as intended, but also look as pretty as possible by conductive and texture painting.
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.
Our RIM tooling cost just a fraction of its relative steel mold used for mass production, making time usually 2 weeks instead of a couple of months. Reaction injection molding by room temperature and fairly low pressure brought the fairly low mold locking pressure as well as packing pressure.
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.
Quality and Service are the true reasons that HONKIA survives and grows up in the market since our establishment. We saw some of our competitors are making money by playing around the quality and then lose the market faster than we think. We do know that is not a sustainable business pattern.
We are a professional supplier. We know what we are doing. We keep a very stable quality level for years. Thanks to our professional production and technical team, our qualified products rate is 99.75% and we are constantly improving it, we hope our clients can get what they paid for.
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.
