RIM Paint Process

Pigmenting and In-Mold Painting

For about 20% of the parts we produce, RIM Manufacturing adds pigment color to the poly component for color throughout the part, or we spray a thin layer of paint onto the mold cavity for the paint to chemically adhere to the part during the exothermic reaction.

Pigmented parts look very good, but this process is only acceptable when paint is not required to cover slight surface imperfections. Parts with a simple surface geometry can be painted in the mold for excellent cosmetics and hiding surface imperfections. However, neither pigmented nor in-mold painted parts have the high-quality finish of post-painted parts.

Class A Post-Painting

Employed for about 80% of the parts we produce, these processes allow for a greatly enhanced, Class A or Class B cosmetic finish. Gloss and texture can be varied to hide part imperfections when the part is new and, more importantly, to camouflage potential scuffing and marring during use. Generally our painters use Polane Polyurethane Enamel paints for their superior appearance and durability.

Silk Screening

This process can produce an excellent look, though it normally adds a day or two to the three to five days that normal painting requires, depending on the number of colors incorporated into design or copy.

EMI Electromagnetic Shielding

Some parts might also require shielding to block electro-magnetic fields to protect electronic devices and people from electromagnetic interference.

Our Expertise with Assembly Builds a Great Reaction

RIM Manufacturing’s insistence on customer success and satisfaction has led us to offer various methods of assembly. We are always looking for ways to lower overall production costs, and partial or full assembly services can help.

Partial Assembly

Often, component parts can be added to the molded reaction injection molding part, reducing cost and improving reliability by reducing the number of touches a part receives. These component parts can be hardware, mounting brackets, hinges, wire harnesses, sensors and more. This process of Partial Assembly might also include using component parts to attach several reaction injection molding parts together, which can later be integrated into the complete system.

Full Assembly

RIM Manufacturing also offers Full Assembly of polyurethane parts. We collaborate with your engineers, designers, and consultants to develop a set of full assembly Work Instructions and manage the procurement of some or all sub-assembly required items. Our Quality Department tests our fully assembled products, certifying operational functionality. We can even manage the customization of shipping containers as part of the Full Assembly process.
