It does not always have to be white

This imaging system is about 30x30x12 inches in size and consists of multiple RIM enclosure parts. The paint finish of the parts can be custom-matched to virtually any color. A light textured paint is the standard but smooth, matte, soft-touch or gloss paints are also possible. It's your choice.

A precise fit

This unit consists of 13 individual RIM parts that all must fit together precisely in this assembly. Complex assemblies like this peripheral equipment for an MRI machine are not a problem in RIM.

Need a better solution than sheet metal?

Are you thinking of a sheet-metal-skin-on-frame concept for your enclosure? Why not make the skin also serve as the structural frame? You can eliminate one entire manufacturing step. Here is a great example of a “skin” with free-flowing curves that is also the structural component. Polyurethane Structural Foam can reduce your total manufacturing cost by reducing the number of parts and assembly time.

Sound Surgical Cart

Carts are great matches for the RIM process as this example of a cart for Liposuction procedure shows. Carts often combine the demand for an elegant industrial design, complex geometry, structural requirements to support the weight of the unit, as well as an impact resistance surface. There are several parts in this unit molded as a single piece that otherwise would have to be assembled from several parts. Free-flowing curves on this cart were easily achieved with Rimnetics tooling and molding expertise. When Form Follows Function, Rimnetics follows Form.

A Food Serving Cart

This good size cart is used in commercial settings like hospitals to serve meals. It needed to be structurally sound and impact resistant; but it also needed to provide for good thermal insulation and had be easily cleanable. The solution to these multiple requirements is molded RIM parts with insert-molded hardware. The excellent chemical resistance of polyurethane is a perfect match for the cleaning solutions that need to be used on this cart.

Silk Screening

Silk Screening with single-color or multi-color logos, icons or decorative features are easily done in RIM.

Need Large parts?

Not a problem with RIM. One of the key advantages of RIM process is the low viscosity of the material injected into the mold. The low pressure during injection allows for very large but complex parts, made from low cost tooling. This example of a medical mobile air filtration cart stands over 6 ft tall and consists of 11 different, large RIM enclosures.

TRY THIS WITH
INJECTION MOLDING!

As a designer you may be used to the common restriction of designing a plastic part with a uniform nominal wall thickness, reinforcement ribs at some percentage of that thickness, and bosses cored out to the bottom. Well, imagine the freedom of design at your disposal if you did no longer have to live with these restrictions. Imagine how much simpler the part design can become, how many corners, nooks and crannies in the geometry can be filled in. How much quicker a tool ready design can be achieved and how much faster and cheaper that tool can be made.

All of the above is possible with our polyurethane structural foam - a solid skin, foamed core sandwich structure that allows you to vary the wall thickness within the same part.

Not only will this design result in the advantages above, but in a much more rigid and self-supporting design.

Medical Device Enclosures

One of Rimnetics’ core markets. No matter if it is a DNA sequencer, a sample analyzer, or any other medical device, RIM plays all its advantages here. With various materials, rated UL94-V0 for flammability, all key requirements for these kind of parts are being met: Complex, 3-dimensional parts, with appealing industrial design, manufactured at medium high volumes – perfect for RIM.

Overmolding

What if you only need a certain area overmolded with a rigid or flexible plastic as in this seat backrest? Since polyurethane is a natural adhesive, it is ideal for just this kind of application that we call overmolding. As in this example, a welded aluminum frame is inserted into the mold and polyurethane injected only in defined areas, leaving other areas exposed.

Gaming Machine

Another great application for RIM components are gaming machines like these, ATMs or Vending Kiosks. Since they are often large in format and run in medium production volumes, the low tooling investment available from Rimnetics make them ideal matches for our process.

Large and complex parts at fraction of the cost:

This is an Audio/Video control panel and measures about 36x24 inches. An injection molding tool would have cost a six digit figure. Rimnetics RIM tooling was only a fraction of that cost. This highly detailed geometry requires an excellent understanding of material flow and tool design.

Industrial Applications

Industrial applications - such as this large industrial filter plate, made from high impact, solid polyurethane. No matter if you are looking for a rigid, elastomeric, high-impact or foam material - or even a combination of such requirements, Rimnetics has a molded solution for your industrial application.

Freedom of Design

Feel free to create free-flowing curves, detailed geometries combined with structural and functional qualities in your part. The RIM material injected into the mold at a very low viscosity will carefully fill out even the most delicate geometries. Rimnetics Engineering will guide you through the steps to construct a RIM feasible design in order to make new project show piece.

Medical Device Enclosures

Medical Device Enclosures are tailor made for RIM and are one of Rimnetics’ core markets. No matter if it is a DNA sequencer, a sample analyzer, or any other medical laboratory device, RIM delivers all of its advantages here. With numerous RIM materials each rated UL94-V0 for flammability, RIM meets all of the key requirements for these components: Complex, 3-dimensional parts, with appealing industrial design, manufactured at medium high volumes – medical devices and laboratory equipment are perfect for RIM.

A Deep Draft

This deep draft part is a hood for a measuring machine. Although the part looks like it is made from 2 clam shell halves, it is actually molded as a single piece. Part consolidation like this have a very positive impact on part cost as well as a lower tooling investment. Only one tool is needed instead of two, no assembly required, no assembly quality issues, no paperwork for the second part. Literally - a one-piece molded solution.

Not a PC Housing, but a Mass Spectrometer

Yet, in the early 80's when PCs were relatively new and not mass produced, their enclosures were made from RIM. So initial and early product runs at medium annual volumes are good RIM opportunities. The low cost tooling investment provides for an easy entry into a new market. Why not “test the waters” with RIM and transition to more mainstream processes like injection molding (with very high tooling investments) once sales of the unit are ramped up?

Subsea and Marine Applications

Subsea and Marine Applications like this propulsion system for a deep sea submersible are ideal candidates for the RIM process. Not only is the polyurethane material salt water resistant, it can also seal and encapsulate other components into your part. In this example, rare earth magnets are encapsulated as part of the electric motor. If a Polyurethane Structural Foam is used instead of a solid polyurethane, the molded part even becomes buoyant.

Like molded rubber

Like molded rubber – only more abrasive resistant. Here is a solid but elastomeric part that is used in an industrial vacuum cleaner. It needs to be flexible, chemical resistant, impact resistant and abrasive resistant. “Check!” on all 4 requirements being met with a single RIM polyurethane material. Another molded solution from Rimnetics.
