We formulate the material and manufacture the part — under one roof. Molded, lined, or printed; tested, certified, and delivered on the date we promised.
If any of that sounds familiar, you're carrying a problem an engineer shouldn't have to carry. Start with your world below — and see how engineers like you ended their hardest failure mode for good.
Rotomolded and laser-sintered flight hardware, made from OEM-qualified materials we formulate ourselves — and delivered at rate, because your program depends on it.
Explore Aerospace & Defense →Seamless linings mechanically bonded to your columns, scrubbers, exchangers, and vessels — engineered for your chemistry, so this turnaround's fix isn't on the next turnaround's list.
Explore Chemical Processing →Produced water, MIC, and biofouling meet their match: pipe, vessels, and caissons lined for decades of service — including BIO-ARMOR™, which eliminates over 99% of the microbes behind MIC.
Explore Oil & Gas →Where concentrated acid shatters ductile iron and wears out PTFE, seamless bonded liners keep concentrate moving — for decades, not maintenance cycles.
Explore Mining →Seamless high-purity vessels and fluid handling, molded in an ISO Class 7 cleanroom — no seams, no crevices, low extractables. Quotes in days, because your fab doesn't wait.
Explore Semiconductor →Ask why a part failed, and the answer is usually decided before the first shift runs: in the material, or in the seam between the people who made the material and the people who made the part.
RMB closed that seam more than forty years ago. One team formulates, compounds, and tests the polymer — and the same team engineers and manufactures the part. The chemistry is designed for the manufacturing, and the manufacturing is designed for the chemistry. That is why the problems that stump everyone else routinely get solved here.
The usual way: you send the vessel to one shop for metal repair, wait on another for NDE, a third for the lining, a fourth for code recertification, a fifth for paint — and you referee five schedules, five quality systems, and five versions of "not our fault."
The RMB way: engineering, ASME-stamped metal fabrication, lining, molding, or printing, machining, testing and NDE, certification, paint, and logistics — under one roof in Fountain, Colorado. Your equipment leaves once and comes back finished, documented, and on the date we said.
See How It Works →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.
How we work, in writing:
ASARCO's concentrated sulfuric acid lines — 94–98% acid at up to 300°F — have run on RMB-lined pipe since 1997. No lined pipe has ever been replaced, and the plant keeps expanding its use.
Read the case study →A quartz-processing vessel that wore out on a schedule was relined seamless — and its service life increased more than 450%.
Read the case study →A Tier 1 aerospace supplier replaced heavy, multi-piece assemblies with rotomolded thermoplastic ducting — cutting cost 45% while reducing weight and part count.
Read the case study →When a produced-water program couldn't wait, 81 pieces were lined with BIO-ARMOR™ and returned in two and a half weeks.

Most plants budget liner and coating replacement as routine maintenance — because nobody told them a permanent option exists. Start here:
Tell us your industry and what's failing — prints and CAD welcome, partial information fine. No project is too early or too small to ask about; some of our largest programs started as one prototype.
What happens after you hit submit: an RMB engineer — not a queue — reviews your inquiry and responds quickly, typically within one business day.
