What vehicle builders and fleets need from a parts supplier
Performance brands, race teams, vehicle builders and transit fleets need parts that are flat, true and on time, from a shop that can turn a drawing or a worn part into finished parts quickly, without tooling or minimums.
From CAD to parts, fast
Send a DXF or STEP and get cut, formed parts back quickly. No dies, no tooling charges, and the next revision is just a new file.
Cut and bent right the first time
Flat patterns developed for our TRUMPF press brake, with bend deductions and hole locations checked before the run, so brackets bolt up.
Rotors that run true
Brake rotors ground flat and parallel, with thickness variation and runout held tight, so brakes don’t pulse and pads bed in evenly.
Marks that survive heat and grime
Part numbers, logos and data matrix codes laser-marked into the part, so they last through powder coat, heat cycles and under-hood fluids.
Fleet parts back in service
Transit and rail brake discs resurfaced and checked against their wear limits, so fleets keep rotors in service longer instead of replacing them.
A real quality system
AS9100D and ISO 9001:2015 certified, with first article inspection, material certs and the documentation tier suppliers ask for.
Auto & transportation capabilities
Brake rotors ground, cut and resurfaced; fabricated parts and busbars for vehicles; the plates and panels that identify and control them; and the fixtures used to build them.

Auto & transportation FAQ
Can you grind high-performance brake rotors?
Yes. We Blanchard grind rotors on a 60″ table, so rotors up to 60″ in diameter fit. Most are alloy steel, but we can grind any metal. Warped rotors are straightened and shimmed before grinding, and we hold thickness, flatness, thickness variation and runout to your spec.
Can you make a rotor from scratch?
Yes. For custom and low-volume designs we laser cut rotors from alloy steel or stainless plate, with drill and slot patterns, then grind them flat and to thickness and mark them.
Do you resurface transit and rail brake discs?
Yes. We resurface brake discs from light rail, monorail and people-mover systems, plus bus and heavy-truck rotors, checking each against its discard thickness and sending a measurement report with each set.
Can you make just one prototype?
Yes. There’s no minimum and no tooling, so a single test-fit bracket is as easy as a production run. We offer fast quoting and fast turnaround.
Do you weld?
No. We cut, form, machine and mark parts, and design-friendly features like tabs and slots make them fast for you or your welder to assemble.
Can you make trailer certification plates?
Yes. We laser-mark certification and tire information plates in stainless or anodized aluminum from the data and wording you provide under 49 CFR 567, serialized for each unit. Your compliance team owns the content; we make the plate.
Do you make VIN plates?
We make plates for manufacturers as part of their production process. We don’t make replacement VIN plates for individual vehicles.
Are you IATF 16949 certified?
No. We’re certified to AS9100D and ISO 9001:2015. Many automotive and transportation customers accept ISO 9001 suppliers, especially for prototypes, aftermarket and specialty-vehicle work; check your customer-specific requirements.
Can marks survive powder coating?
Yes. We can mark deeper so codes read through coating, mask the mark area, or mark after finishing, depending on the part and the code.
