Failure 01
Plate will not sit flat
Cold rolled steel springs back 0.3 to 0.8 degrees after every bend. Uncorrected, the plate bows past 0.5 mm and the pad contact goes uneven.

Four ways a backing plate fails at the axle.
Flatness, hole position, edge coating, and every anchor weld are checked before a plate reaches a carton.
VIA checking bench
CHECK critical dims · every lot
Checked before pack.
Every plate is verified for flatness on a CMM pallet, hole position, coating thickness at five points, and weld strength before release.

Failure 02
Holes miss the bolt circle
Hole position past Ø0.20 mm TP side loads the assembly, drags the pads, and fades one corner. The die is held to Cpk 1.67 and checked every 5,000 shots.

Failure 03
Rust creeps from the cut edge
Coating runs thin on sheared edges and punched holes. Rust starts there, tunnels under the e-coat, and shows up only at disassembly. Edge thickness is inspected and salt spray runs ≥480 hours.

Failure 04
Anchor weld lets go
A cold weld on the shoe anchor holds until heat and vibration find it. Every batch runs a pull test at ≥3.5 kN/cm² per SAE J2432 before it ships.

A note from the founder
I know what happens when a plate is not flat.
For 12+ years I was the buyer. The drawing looked right, the supplier said it was easy, and the real problem showed up in service. One plate bowed past spec. One hole pattern drifted with die wear. One anchor weld let go under heat. Then the whole program became my problem.
FlatnessStamp it and ship what comes out.Correct springback in the die, gauge 100%.
Hole positionTrust the die until parts bind.Check the die every 5,000 shots, SPC on TP.
CoatingCoat it and hope edges hold.Measure 5 points, salt spray every batch.
On your backing plates that means our network builds them and we answer for blanking, forming, welds, coating, marking, inspection, packing, and delivery. A backing plate is only good when it sits flat and quiet for the life of the vehicle.

From steel coil
to one finished plate.
One controlled part journey, managed by VIA INDIGOS from coil to your dock.
±0.05 mm blankShearing
Coil steel is cut to flat rectangular blanks. Blank thickness held to ±0.05 mm so every plate downstream starts from the same sheet.
Heat lot loggedBlanking
The press cuts the round plate outline from the strip. Net shape blanks, ±0.15 mm on the outside diameter, heat lot logged per coil.
Ø0.20 mm TPPunching
Center axle hole, bolt circle, and anchor slots are pierced. Hole true position held to Ø0.20 mm TP with the die checked every 5,000 shots.
Springback correctedForming
The web and rim are formed with springback compensation of 0.3 to 0.8 degrees built into the die, validated per coil lot before production.
≥3.5 kN/cm² pullWelding
Shoe anchors and brackets are MIG welded on drum plates, robotic cell or qualified welder by volume. Pull tested at ≥3.5 kN/cm² per batch.
Lot traceableMarking
Part number, heat code, date, and country of origin are laser marked on every plate, so traceability survives coating and service.
15-25 µmPlating and coating
Powder coat by gun, cathodic e-coat, or zinc plating selected by spec. Coating thickness checked at five points per ISO 2178.
Lot ID on cartonPacking
Every plate is bagged, layered with foam separators, and boxed for export. Lot ID on every carton, count verified at closing.

Inspection sweep before release
The bench is not a final photo prop. It is where flatness, hole position, coating thickness, weld strength, and count are tied to the same lot before the carton is closed.
Materials. DC01 / DC04 cold rolled steel per EN 10130 for passenger platforms. S420MC / S460MC HSLA per EN 10149 for truck and heavy duty. AISI 409 stainless for corrosive and EV rear axle work.
Hole position Ø0.20 TP, checked every lot
Flatness gauged on the CMM pallet
Robotic welding that holds tolerance
even after the first shipment.
Shoe anchors on drum backing plates are welded in fenced robotic arc cells for volume programs, so the torch path, weld location, and process settings stay repeatable from shift to shift. We control fixture readiness, weld consistency, batch inspection, and production follow-up on the shop floor, instead of leaving buyers to chase updates after approval. Where required, weld strength is validated through customer-approved pull, shear, or destructive test methods before repeat production begins.

Tooling is where it starts.
Control it or lose it.
- We never depend on production suppliers to build critical tooling while chasing production schedules.
- Dedicated toolmakers in our network handle fixtures, gauges, and tooling discipline, while the production supplier stays focused on output, lead time, and scale.
- That split gives buyers better visibility, cleaner accountability, and fewer surprises after approval.

Questions we get on the first call.
If your plate matches an existing die family we quote from it and you pay no tooling. If the geometry is yours, we quote the die separately with milestone payments, and the tool belongs to you once it is paid in full. It stays documented in a tooling passport with photos at every gate, and it never runs for anyone else.
Yes, and it happens more often than you would think. Ship us one good part and we reverse engineer it: the plate is scanned and measured, a drawing is created for your approval before anything is cut, and the quote follows from that drawing so both sides are pricing the same part.
Stamped parts earn their keep with repetition, so programs from a few thousand plates a year upward price well, and high volume prices better still. Below that we will tell you honestly if the die cost does not pay back, because a quote that hides that math always comes back to bite both of us.
DC01 and DC04 cold rolled steel per EN 10130 covers most passenger platforms. S420MC and S460MC HSLA per EN 10149 carries truck and heavy duty loads at thinner gauge. AISI 409 stainless handles corrosive duty and EV rear axles. Every coil arrives with an EN 10204 3.1 mill certificate, and a new coil lot runs a five part springback validation before production starts.
We quote one landed number: part, coating, packing, freight, and duty to your dock, so you compare totals instead of factory prices. With current tariff rates on Chinese brake components, India lands lower on most backing plate programs, and where it does not, we will show you the math rather than argue with it.
Whatever your quality system needs: PPAP up to Level 3, CMM reports with SPC charts on hole position, coating thickness records per ISO 2178, salt spray results per ISO 9227, weld pull certificates per SAE J2432, and material certs tied to the heat number laser marked on every plate. Ask for the sample bundle on the first call and we send a real one.
