RIM Manufacturing

“THE REACTION MAKES ALL THE DIFFERENCE”
THE MOST ADVANCED CUSTOM REACTION INJECTION MOLDING COMPANY

RIM Company | Reaction Injection Molding Manufacturers

RIM Manufacturing offers the widest range of chemistries to perfectly match your needs. We are industry experts who constantly look to improve our Reaction Injection Molding processes by contributing significant design knowledge and proficiency.

Every member of RIM Manufacturing is dedicated to making your RIM design successful in every phase of the production process – part and CAD design, mold design, manufacturing, part production, secondary processing, painting and silk screening, assembly, packaging, shipping, and beyond.

When You Consider All the RIM Advantages, We Know You’ll Have the Best Reaction. RIM Manufacturing is the Partner that is Uniquely Positioned to Accelerate Your Company’s Success

THE RIGHT CHEMISTRY FROM THE RIGHT COMPANY

The chemical reaction that distinguishes Reaction Injection Molding from typical injection molding makes all the difference in how your products perform. RIM Manufacturers use low viscosity liquid polymers which expand and harden in the mold at much lower temperatures than those of plastic injection molding or thermoforming. Additionally, your RIM designs can be much more intricate with a greater range of weight, strength, density, and hardness.

Imagine the reaction when your parts perform better and cost less.

With RIM, you get positive reactions not only from customers and end users, but also the people with their eye on your bottom line.

You can achieve significant advantages over injection molding, vacuum-forming, thermoforming, pressure-forming and cast molding in design, flexibility and cost-efficiency, as well as wide ranges of part size, design uniqueness, and overall superiority.

Since our processes require lower temperatures and pressures than typical ones, RIM polymers can be injected into cost-efficient aluminum molds, costing much less than steel molds and lasting longer. They may never need to be replaced and can be modified much less expensively.

Get better reactions to your designs.

RIM gives you design options otherwise impossible. Accommodating small to very large parts, it imparts structural integrity, tight tolerances and greater ranges of wall thickness within the same part. Plus, several parts can be combined into one.

Design solid, elastomeric, structural foam, or flexible foam parts with your precise characteristics of impact resistance, dimensional stability and strength, wear- and corrosion-resistance, 94V-0 and HB ratings,
thermal insulation and more.

Greater RIM Design Flexibility

Choose your RIM parts’ precise characteristics:

  • Structural integrity and tolerances
  • Impact resistance, dimensional stability
  • Strength, wear- and corrosion-resistance
  • Thermal and electrical insulation
  • Sound absorption and natural adhesion
  • Solid, elastomeric, rigid- or flexible-foam

Create more than individual parts:

  • Combine several parts into one
  • Over-mold metal, wood, glass, and more
  • Encapsulate parts – cable, valves, circuits

ABOUT US

The way we work gets a very positive reaction. Founded in 1979, RIM Manufacturing, LLC has grown to be one of the largest independently owned (RIM) Reaction Injection Molding companies in the country specializing in custom RIM Molding. ISO 9001:2015 and ISO 13485:2016 Certified for Reaction Injection Molding, we optimize RIM processes and RIM design for our clients with our significant design expertise.

While we are one of the most experienced Reaction Injection Molding manufacturers in the business, our plant floor space exceeds 50,000 square feet and our three-acre site allow us to be flexible in our process, and nimble in our responses to client needs. Our Central US location in the Dallas/Fort Worth area can save time and cost for transportation.

When you consider all these advantages, you’ll have to have this reaction: RIM Manufacturing will accelerate your company’s success

The reaction makes all the difference. Reaction Injection Molding relies on low-viscosity liquid polymers expanding, thickening and hardening in the RIM mold through a variety of chemical reactions at much lower temperatures. So, our processes can accommodate much more intricate designs than ordinary plastic injection molding or thermoforming and offer a greater range of desired weight, strength, density and hardness characteristics.

The slightly longer production time of Reaction Injection Molding is more than offset by its benefits to design, flexibility and cost-efficiency, not to mention the wide ranges of part size, design uniqueness, and overall superiority.

These processes ensure that your customer and end users are going to give your products a better reaction

DESIGN FLEXIBILITY

A better reaction to your design. Reaction Injection Molding gives you design options otherwise impossible. Accommodating small to very large parts, RIM injection molding imparts structural integrity, tight tolerances and greater ranges of wall thickness within the same part. Plus, several parts can be combined into one.

Design solid, elastomeric, rigid foam, or flexible foam parts with your precise characteristics of impact resistance, dimensional stability and strength, wear- and corrosion-resistance, thermal insulation and more.

Create polyurethane parts that over-mold other materials like metal, wood or glass or even other parts such as cable, valves or circuitry.

Designs appreciated for enhanced appearance and performance – isn’t that the reaction you’re looking for?

COST BENEFITS

Imagine the reaction when your parts perform better and cost less.

Our aluminum molds typically cost 70% less than steel molds and last longer, since they are used at lower pressures and temperatures. They may never need to be replaced and can be modified less expensively.

Lead-time to production is also considerably less, reducing your time to achieve profitability. Our parts costs are very competitive with other polyurethane processes and almost always less expensive for parts which are large or have high demands for structural integrity, unusual or complex geometry, and design tolerances. Over-molding and combining several parts into one can bring about further cost savings.

When cost savings are combined with production advantages, you get a very positive reaction
