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.

Every industry asks the material a different question. Pick yours — we'll take it from there.
Concentrated acids and caustics at temperature — without re-lining every five years.
Explore →Contamination-free fluid handling, molded and assembled in an ISO Class 7 clean room.
Explore →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.
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.
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.
Fabricated, lined, molded, or printed; machined, tested, certified, painted, and shipped — by one accountable partner, on the date we promised.
The material decides the method. Whichever it is, it's made here, tested here, and shipped under one PO.
Seamless bonded liners for pipe, fittings, and vessels — chemical resistance with no weld seam to fail.
Learn more →Complex, seamless thermoplastic parts: tanks, ducts, fittings, and high-purity vessels.
Learn more →Production-grade laser-sintered and SLA-printed parts — no tooling, flight-ready materials, full traceability.
Learn more →If the part exists — or should — bring us the business case. Capabilities here keep expanding.
Talk to an EngineerSmall-batch custom formulations the big material houses won’t touch — compounded, ground, and sold to you.
Learn more →Certified hot-gas plastic welding and AWS-qualified metal welding — the step customers keep asking for.
Learn more →ASME steel fabrication, machining, testing, and finishing — one PO, one partner, the part arrives done.
Learn more →Different industries, one method: identify the material, engineer the part, prove it before it ships. Look past the industry — the material science may be your answer too.
A quartz-processing vessel that wore out on a schedule was relined seamless — and its service life increased more than 450%.
