Thermoplastic innovation that delivers.
Turning complex challenges into engineered solutions built to perform.
RMB is the custom thermoplastics manufacturer that formulates the material and makes the part under one roof — rotational lining, rotational molding, laser sintering, and custom compounding — for engineers whose parts can't fail.
Start with your world.
Every industry asks the material a different question. Pick yours — we'll take it from there.
Aerospace & Defense
Weight, flammability, and traceability — on parts that have to fly.

Chemical Processing
Concentrated acids and caustics at temperature — without re-lining every five years.
Explore →
Oil & Gas
Saltwater, brine, and microbial corrosion that eats through steel.
Explore →
Mining
Sulfuric acid service where liners fail and downtime is billed by the hour.

Semiconductor & High Purity
Contamination-free fluid handling, molded and assembled in an ISO Class 7 clean room.
Explore →Most manufacturers buy it off the shelf. We engineer ours.
RMB formulates the polymer and manufactures the part. Nine times out of ten, your problem is a materials problem: temperature, pressure, chemistry, purity. We formulate, compound, and grind our own resins — then build the part from them.

The RMB Path — Problem. Polymer. Performance.
-
Tell us what's failing.
Send the application through the form, or talk directly to an engineer. Incomplete information is fine — we'll ask the right questions, and you'll hear back fast, typically the same day.
-
We engineer the solution together.
Material selection — or a custom formulation — plus design for manufacturability, drawn from six decades of polymer engineering. Straight answers on fit, alternatives, and trade-offs.
-
We build it, prove it, and deliver it. Complete.
Fabricated, lined, molded, or printed; machined, tested, certified, painted, and shipped — by one accountable partner, on the date we promised.
How we solve it.
The material decides the method. Whichever it is, it's made here, tested here, and shipped under one PO.
Rotational Lining
Seamless bonded liners for pipe, fittings, and vessels — chemical resistance with no weld seam to fail.

Rotational Molding
Complex, seamless thermoplastic parts: tanks, ducts, fittings, and high-purity vessels.
Learn more →Additive Manufacturing
Production-grade laser-sintered and SLA-printed parts — no tooling, flight-ready materials, full traceability.
Learn more →
In-House Resin Formulation
Small-batch custom formulations the big material houses won't touch — compounded, ground, and sold to you.
Learn more →
Plastic & Metal Welding
Certified hot-gas plastic welding and AWS-qualified metal welding — the step customers keep asking for.
