Advantages of Reaction Injection Molding (RIM) Products

The benefits of reaction injection molding (RIM) products over the same items made from metals, plastics and woods are many. The durability, color variability, flexible scheduling and the affordable costs are worth describing.

Durability of RIM products

A major selling point on the benefits of RIM products is their durability.Injection mold manufacturer Polyurethanes are the result of a two liquid component mixing that combines a polyisocynate component and a resin mixture. They are combined in a pressure chamber with a psi of up to 2000 and fed into a mold. The pressure of the compartment is what determines the hardness of the product, with the higher the psi, the harder the end result. Wheel chocks require a very hardy and durable surface, as they are intended to stop a vehicle from moving if they are not placed in park, have no emergency brake and have a vehicle malfunction. Wheel chocks are used in the utility, telephone, construction and mining industries, as well as aviation and automotive businesses. A professional engineering team will be in place at a reliable RIM manufacturer that can assure the quality of the product outcome, whether a tough, resilient surface is needed or a more pliable and soft device is required.

Color Variability of RIM products

Making your product identifiable and specific to you company with custom color is a great benefit of RIM. The two pieces of the RIM puzzle can be purchased “raw” with no color, or with color included in one of them. To obtain custom colors, dyes can be formulated to match what you are looking for. Colors can be added first string – before the components are mixed, or on third string as they are mixing – the preferable way to colorize the object. With third string coloring, a much better color match is realized, and it makes it easier and quicker on the manufacturer to change colors quickly.

Flexibility of RIM Scheduling

Once a mold for a particular product has been tooled, the turnaround time for production can be just one week or less with a reputable reaction injection molding manufacturer. The process itself requires the loading of the RIM components into the chambers, injecting the proper dyes into the mix head, and running the test drive. Once the process has been established, the machine can dispense 140 to 360 pounds of material per minute. The mold releases the object formed in three to five minutes, with individual finishing work and packaging next. When that manufacturer uses hard tooling and third string colorizing instead of soft tooling and first string color, the speed with which the product can be delivered is almost guaranteed and is an excellent benefit of RIM technology.

Cost of RIM products

By far, the benefits of reaction injection molding must include the affordability of this process. With precise tooling procedures and quality operators, it can be affordable to produce large, over-sized items in low quantities, and it’s also affordable to produce high volume products at a great price. To realize the benefits of reaction injection molding technology, align your company with a RIM manufacturer that can provide the above specifications with a quality product.
