Commercial Tractor Hood

32.5L x 21.5W x 22H     (7 lbs.)

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

RIM is ideal for large parts that need to be lightweight, like the above tractor hood, which is only 7 pounds.

Medical Device Swivel Tray

18L x 18W x 5H     (2.5 lbs.)

RIM, and Structural Reaction Injection Molding, give you design options otherwise impossible. RIM is able to accommodate small to very large parts, impart structural integrity, tight tolerances, and greater ranges of wall thickness within the same part. Plus, several parts can be combined into one.

Consider the intricacy of the above design, with RIM, the medical device swivel tray doesn’t need as many post-production additions or assembly steps as other manufacturing options.

Laboratory Device Base

58L x 27W x 3.25H     (26 lbs.)

Since our RIM process requires lower temperatures and pressures than other manufacturing processes, RIM polymers can be injected into cost-efficient aluminum molds. These cost up to 70% less than steel molds and last longer. They may never need to be replaced and can be modified much less expensively.

For the laboratory device base above, the size, weight, and number of products needed, along with the intricacy of the design, made RIM an ideal process for the project.

Whatever your specifications, we will work with you to check that RIM is the optimal process for your project. Depending on wall thickness and strength, ribs, draft, bosses, holes, grooves, and vent needs, we will help you select the right system and chemistry to achieve the correct process and end product.

RIM Manufacturing Will Help You Find the Best RIM Design for Your Project 

  • Elastomeric– for RIM parts with superior impact strength, durability, dimensional stability, and resistance to corrosion, abrasion, and wear.
  • Solid– produces RIM parts similar to those created with thermoforming or thermoplastic systems, but these allow variation in wall thickness throughout a part without visible sink marks. Typically, the minimum wall thickness is 1/8” to 1/2”.
  • Rigid Foam– a blowing agent creates a high-density skin around a low-density microcellular core. This skin gives the RIM part firmness and durability, while the low-density core reduces the part design’s weight. Wall thickness can vary from 1/4” to 11/2”.
  • Flexible Foam– this system’s blowing agents create self-skinning foams. The thickness of the skin and density of the foams can be adjusted to achieve the precise flexibility, firmness, and support characteristics your RIM part design requires.
  • Reinforced RIM (RRIM)– the Elastomeric system with glass or mineral fillers introduced to produce parts with greater rigidity.
  • Structural RIM (SRIM)– Solid or Foam chemistries can incorporate long-fiber reinforcements, like glass mats, to increase stiffness and impact resistance for your RIM design.

Benefits of Reaction Injection Molding

orange polyurethane reaction injection molding part

RIM Molding is an excellent process for producing large, lightweight parts. The sweet spot for volumes ranges from a few hundred to several thousand parts per year.  And because of the wide variety of chemistries offered, parts produced can be structural foam, flexible foam, elastomeric, or solid RIM.  What’s more, the low temperatures and low pressures incorporated within the RIM process,  offer design opportunities that are superior to other processes such as injection molding, thermoforming, vacuum molding, and cast molding.

Additional Advantages of Reaction Injection Molding:

  • Variable wall thickness
  • Molded-in bosses, ribs, inserts, tabs, or undercuts
  • Flexible cosmetic surfaces or part design
  • Encapsulation (over-molding) capabilities
  • Dimensional stability
  • Chemical resistance
  • In-mold painting or post-paint
  • Low tooling cost

Technical Properties include:

  • Impact resistance
  • Dimensional stability and strength
  • Design tolerance
  • Wear- and corrosion-resistance
  • Thermal insulation
  • Electrical non-conduction
  • Sound absorption
  • Natural adhesion

Longer Cycle Times

To achieve creative and uniquely designed parts using RIM Molding, the production process requires longer cycle times.  The liquid chemicals used in RIM molding will more easily flow within complex tools to fully fill the cavity of the mold and, therefore, take longer to become a finished part.  A process like injection molding, which incorporates high temperatures and high pressures to quickly fill the mold cavity, has a much shorter cycle time.

Our Reaction Injection Molding (RIM) Process

Reaction Injection Molding part
Reaction injection molding and plastic injection molding have almost the same name, so even experienced engineers and designers may think they are the same. But the ‘reaction’ creates a big difference.

The Reaction Injection Molding Process: Pressure & Temperature

Step 1: Polymer Liquids

The RIM molding process begins with polymer liquids (polyol and isocyanate) stored in large storage tanks and dispensed by large, high-pressure industrial pumps. The polymers are recirculated from the storage tanks to a multi-stream mix-head on the machined aluminum mold and back to the storage tanks in a continuous loop.

Step 2: Mixing

When each part is made, a piston or plunger inside the mix-head retracts, breaking the continuous loop, and the polymers mix at a high velocity (approximately 1200 psi) to ensure the proper combination and mixture of the polymers. The resulting polyurethane enters the mold through the after-mixer, which maintains the mixture’s properties while reducing its velocity to 95-100 psi, a much lower pressure.

Step 3: Molding

Since these liquid polymers require less pressure and lower temperatures than typical ingredients, they can be injected into cost-efficient aluminum molds, lowering tooling costs. The molds are then moderately heated (~190°), but the resulting exothermic reaction quickly brings the materials to (~325°) and promptly cures the part inside the mold.

Step 4: Curing & Cooling

Cure times vary from less than a minute to several minutes, depending on the part’s size, geometry, function, and thickness. Polymers and RIM processes can be chosen to produce solid, elastomeric, rigid-foam, or flexible-foam finished polyurethane parts.

Differences Between Reaction Injection Molding & Plastic Injection Molding

Unlike plastic injection molding, reaction injection molding (or RIM molding techniques) utilizes low-viscosity liquid polymers in thermoset – not thermoplastic or thermoforming – processes.

Through a variety of chemical reactions, these polymers expand, thicken, and harden only after they’re injected into a heated mold, accommodating much more intricate designs than ordinary plastic injection molding.

Raw materials and polyurethane reaction techniques can be selected and even customized to precisely deliver desired weight, strength, density, and hardness characteristics. The result is large polyurethane parts with a much lighter weight than those created by more commonplace processes.

Learn the Advantages of the Reaction Injection Molding Process from RIM Manufacturing

Reaction injection molding not only offers certain advantages over injection molding, but also vacuum-forming, pressure-forming, and cast molding.

The admittedly 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 colors.

What are the Benefits of Reaction Injection Molding?

new green reaction injection molding part
“Reaction Injection Molding “RIM” is a Thermoset process where low-viscosity liquid polymers and isocyanates are mixed at high-pressure (2000 psi) and injected into temperature-controlled molds at low-pressure (150 psi). An exothermic reaction occurs as the temperature of the liquids reaches 350 degrees Fahrenheit before cooling to become a solid polyurethane part.”

When Should You Use RIM Molding?

RIM Molding is good for low volume and large, lightweight parts. The RIM process may be a better solution in certain situations because of the chemistries offered, or because of the low temperatures and low pressures used in RIM versus other injection molding processes.

RIM Molding for Over-Molding

RIM Molding uses lower temperatures and lower pressures, which make it the most effective process for over-molding production parts.  Over-molding materials like sheet metal, steel, and other substrates allow the combining of multiple parts into a single part.  RIM Molding is also perfect for over-molding sensitive materials, like circuitry or valves, that would otherwise be destroyed by the high operating temperatures and pressures of injection molding.   

RIM Molding for Varying Thickness

The RIM Molding process provides greater design flexibility because it allows varying wall thickness within the same part and without sink or deformities.  Wall thickness throughout an injection molded part must be uniform, otherwise, the part will deform as it cools.

RIM Molding for Various Sizes

Injection molded parts are typically small in size. To produce one large part generally requires producing several smaller parts and then assembling to create the larger part. Tooling costs will be significantly higher than building one large RIM tool. And the single RIM molded part eliminates assembly costs associated with combining the smaller injection molded parts into one larger part.

Reaction Injection Molding for Colors

Large RIM molded parts can be molded in color, which is cosmetically appealing, and can be shipped to the customers immediately upon demolding with some minor trimming of flashing – or excess material. Whereas large injection molded parts often have significant, visible, and unappealing ‘flow lines’, which require painting for cosmetic acceptance.

RIM Molding Tooling Materials & Costs

Reaction injection molding uses aluminum tools instead of steel tools, which translates to lower tooling costs per mold.  Unlike injection molding tools, which are made of steel to sustain the high operating pressures and temperatures, RIM molding uses machined aluminum tools because of the low operating pressures and temperatures.  Therefore, the capital requirement for RIM tools is significantly less than injection molding, by as much as 2 to 3 times!

RIM (Reaction Injection Molding) vs. Plastic Injection Molding: What Are the Differences?

Trilogy Accelerator Machine from reaction injection molding

Product manufacturers may look to injection molding when they need to produce custom parts. However, there are several processes available for producing plastic parts. Depending on the size of the part, the geometric design, the functionality, the quantity required, and the capital expenditure budget, RIM (Reaction Injection Molding) may be a better option.

Though these two molding processes are similar, they are also very different – here are a few of the key differentiations.

The Processes 

The Reaction Injection Molding (RIM) process uses a sophisticated closed circuit dispensing machine to mix two-component non-viscous liquid polyurethane materials (a polyol and isocyanate) at high-pressure within the mix-heads mixing chamber. This combined material is then injected into machined aluminum tooling at low pressure and low temperature.

The Plastic Injection Molding (PIM) process uses an injection machine to melt plastic resin pellets into a viscous molten material which is then injected, at high pressure and high temperature, into steel tooling.

Design Benefits 

Reaction Injection Molding (RIM) is perfect for large, light weight parts with varied wall thickness and unique geometric design. Additionally, RIM’s molding functionality allows for the combining of several parts into one part and easily accommodates over-molding materials like sheet metal, steel, circuitry, valves, etc.

Injection Molding is perfect for small parts and high volumes. The more simplistic the design, the better the efficiency for production.

Cost Benefits 

There are several cost benefits to using the RIM process:

  1. RIM uses machined aluminum tools that can easily be modified for subsequent design changes. The cost of aluminum tooling is significantly less than steel tooling, used in injection molding, and there is little to no maintenance.
  2. Aluminum is easier to machine than steel allowing the RIM process to bring a product to market much faster than injection molding.
  3. The RIM process uses non-viscous liquids which allow for several smaller parts to be molded into one larger part thereby reducing the costs associated with inventory management and assembly.
  4. Unique design features, including over-molding increase the functionality and eliminate potential assembly labor.

However, because the RIM process is better suited for larger parts, the per part cost will be higher than injection molding.

Injection Molding requires steel tools in order to accommodate the process of high pressures, high temperatures and highly viscous material. While the capital expenditures and lead-times are significantly higher and longer than RIM Molding, the rugged steel tools allow for faster processing of parts resulting in a significantly lower part cost than RIM.

How Reaction Injection Molding Can Reduce Manufacturing Costs

VanDerLande product from Reaction injection molding

Companies continually strive to improve production costs. Whether you need a large, lightweight, or complex, 3-D part, or a limited tooling budget, RIM can be the solution you’re looking for.

Reaction Injection Molding (RIM)  is an example of an innovative manufacturing process that lends to high-quality polyurethane parts.

What Is Reaction Injection Molding (RIM)?

RIM creates end-use products or parts by combining two liquid polyurethane chemicals – an isocyanate and a polyol. These chemicals are isolated as they re-circulate through a sophisticated dispensing machine until a part is produced. 

Parts are produced when the chemicals enter the mixing chamber of the mix-head, which is attached to a machined aluminum mold with heated water lines.  The chemicals impinge at high-pressure (3000 psi) and flow into the mold at low pressure (150 psi).  An exothermic reaction occurs within the mold as the temperature reaches 350℉.  The mold’s water lines quickly wick away the heat and allow the molder to quickly withdraw parts by hand.

Tooling Cost Advantages of Reaction Injection Molding

By using aluminum molds, instead of steel molds, your overall capital expenditure can be dramatically lower – especially for larger parts.  We still use aluminum molds manufactured over 30 years ago!

Injection molding requires high pressures, high temperatures, and highly viscous materials.  All of these elements place tremendous stress on the mold, which is why steel is required to produce conforming parts and minimize mold maintenance. 

Comparatively, more affordable aluminum molds are perfect for the RIM process and its integration of low pressures, low temperatures, and non-viscous materials.

Additional Benefits of RIM Molding

  • RIM is best suited for larger parts and lower volumes.  However, RIM Manufacturing produces smaller parts by the thousands too. 
  • RIM offers tight tolerances with more cosmetic freedom in part design, variable wall thickness, geometric complexities, and the ability to combine multiple parts into one single, seamless part. 
  • Parts can be solid, elastomeric, structural foam, or flexible foam.
  • RIM parts can be pigmented, in-mold painted, or post-painted to provide the required cosmetic finish at the right price point.

4 Cost Benefits of Reaction Injection Molding for Manufacturing

Theranos medical device from reaction injection molding

Manufacturing firms are always looking to lower their overall production costs. Especially now that we’re in the middle of a global economic recession, companies strive to minimize their expenses and maximize their cash reserves.

One of the solutions that can help cut your production costs is reaction injection molding or RIM. Compared to the standard or thermoplastic injection molding, RIM is a more economical plastic manufacturing method. It offers plenty of cost benefits, helping manufacturing firms save on assembly expenditures. 

What is Reaction Injection Molding?

RIM uses thermoset polyurethane liquid chemicals instead of standard thermoplastic resin pellets. The process starts by mixing two base polymers, causing a chemical reaction that thickens and expands the polymers. The polymers are then injected into the mold, where they are heated until they harden.

The polymers used in RIM have a lower viscosity than the ones used in standard plastic injection molding. It’s easy to achieve your desired density, weight, thickness, and hardness with RIM. 

Here are some of the cost benefits you get with reaction injection molding.

1. Lower Machine Costs

RIM features low injection pressures and low processing temperatures, unlike the more intensive plastic injection molding process. The mold also requires less clamping force to form the thermoset plastic materials. There’s little need for external force or pressure in RIM since the polymers used rely on chemical reactions and low processing pressures.

For these reasons, RIM has more economical processing machines than other manufacturing processes of plastic parts. Plastic injection molding, for example, needs high-grade steel machinery to support high pressure and temperature. 

2. Lower Tooling Costs

RIM also offers lower tooling costs. The thermoset polymers expand on their own exerting less stress on the machined aluminum tools.  These are more affordable than the high-grade steel tooling required in thermoplastic injection molding. 

RIM tooling experiences little or no wear because of the non-viscous chemicals used to produce parts.  Therefore, tool maintenance, if any, is minimal thereby eliminating or significantly reducing mold maintenance costs over the life of a project.

Because it uses low-cost tooling, RIM significantly reduces capital costs associated with new projects and is ideal for large productions that require a large number of molds.

3. Shorter Lead Times

Lead time is an important consideration in manufacturing. The shorter your build cycle, the quicker you can get your product to the market.  Because aluminum machines faster than steel, RIM tools require shorter lead times than injection molding tools, which saves you money and time.

You can enjoy shorter tooling lead times with reaction injection molding. The typical build cycle of complex molds is four to six weeks.

4. Lower Finishing Costs

Finally, RIM allows in-mold painting. You can produce aesthetically pleasing finishes, such as high or low glosses or color variety. In-mold painting saves you time, manpower, and even production floor space during the finishing process. It can also reduce the costs that usually come with secondary finishing.

The Applications & Advantages of Reaction Injection Molding (RIM) over Thermoforming

Spacelabs - Akron Thermoforming product

Plastics play a huge role in manufacturing. They are present in virtually every industry. From automotive to medicine, plastic materials are utilized as end products and components for assembling a more complex product.

However, these plastic products are not readily available in the market, and they have to undergo a manufacturing process within a plant dedicated to designing and molding plastics.

RIM Manufacturing is an example, and helping to design and molding plastic end products or components is something we do exceptionally well. To give you a clear picture of what we do, we’ll compare the process we use, Reaction Injection Molding (RIM), with another popular plastic manufacturing method – thermoforming.

What Thermosetting & Thermoforming?

Let’s cover the basics.  Reaction Injection Molding is a Thermoset process whereby low-viscosity liquid polymers and isocyanates are mixed at high-pressure (2000 psi) and injected into temperature-controlled molds at low-pressure (150 psi).   An exothermic reaction occurs as the temperature of the liquids reach 350 degrees Fahrenheit before quickly cooling to become a solid polyurethane part. Thermoforming, on the other hand, draws a pliable plastic sheet stock down onto a heated mold.  A vacuum may be used to evacuate any air and accurately reproduce the details of the mold.

The key difference between the two is significant.  RIM (Thermosetting) allows for tight tolerances, unique design, and molded in ribbing and bosses.  Thermoforming, on the other hand, is good for simple design parts with limited functionality and cosmetic finish.

The Applications of Thermosets & Thermoplastics

The different qualities that thermosets and thermoplastics possess dictate where and how they may be applied.

For example, thermosets are ideal for products exposed to high temperatures because of their incredible heat resistance. For this reason, manufacturers use thermosets for the body and components of household and kitchen appliances. These machines tend to generate excess heat. If thermoplastics are used for these products, they could warp at best and melt and mess up the electricals at worst.

Thermoplastics, on the other hand, are ideal for single-use plasticware like cups, drinking bottles, food containers, and grocery bags. CDs, DVDs, children’s toys, sports equipment, and eyeglass lenses are also made from different thermoplastics.

Thermoset vs. Thermoplastic: Which Should You Choose?

Which is the better material to use for your products? The answer depends on the uses of your products. Our opinion at RIM Manufacturing, however, skews in favor of thermosets. We attest to the quality of thermoset plastic, and its heat-resistance and physical integrity are additional perks. More importantly, it’s easier for us to create intricate details like textures, irregular corners, and protrusions using reaction injection molding. Thermoforming is more acceptable for simpler designs.

Over the years, the process has become popular because of the design flexibility and cost-effectiveness when compared to other manufacturing processes.

The Advantages of the RIM Process

Apart from its affordability, the benefits of RIM Mold and Part Design are useful to our customers for the following reasons.

  • Creation of Large Parts: RIM uses low viscosity polyurethane liquids, making it easier to create uniquely designed, large plastic parts without compromising performance.
  • Highly Cosmetic Surface Finish: The process accommodates finer design details and surface finish to produce quality pigmented or in-mold painted parts.
  • Variable Wall Thickness: The chemical reaction used to form parts is highly customizable, giving designers better control to vary wall thickness and eliminate sink marks.

All of these allow for the creation of high-quality, aesthetically pleasing, and long-lasting plastic parts. In choosing the RIM process in manufacturing your product parts, you join a select group of industries.

Industries that Utilize the RIM Process

It’s difficult to beat results, making the RIM manufacturing process highly sought-after. In the last few years, more businesses across many industries have made the switch to the RIM process. It has resulted in high-quality, high functioning, finished products.

Automotive Industry

RIM is widely used in the automotive industry. Most car manufacturers use it to create large parts, including bumpers, quarter panels, decorative trims, and wheel arch liners.  The durability and flexibility of hardened polyurethane provide these parts with ample tensile strength and shock resistance. Some automotive brands also use RIM to create whole prototypes for testing purposes and show cars for their showroom displays.

Heavy Equipment Industry

The heavy equipment industry uses the RIM process in creating intricate parts, specifically for heaters, mobile generators, and light towers. The polyurethane solution is resistant to corrosion and other forms of wear and tear, resulting in tough and low-maintenance parts. The process is also used for B-side geometry, in-mold paint, and molded-in inserts. All of these give designers better control in building the final products. 

Healthcare Industry

Although the RIM process is largely known for its ability to create large parts, the healthcare industry utilizes it to design and manufacture intricate parts for medical devices (e.g., ophthalmic enclosures for eye examination equipment). In some cases, the RIM process is used to make whole devices, such as an electronic spray system, a DNA analyzer, and a full-body analysis machine. Polyurethane plastic is also resistant to bacteria growth, making it a hygienic alternative to other materials.
