We weld the wire and tube frame under the seat cushion.

Wuhan Yaxin Auto Parts builds seat cushion and seat back frame welded assemblies for Tier-1 seat makers — wire bending, tube bending, laser-cut sheet metal, then robotic MIG and spot welding into a finished assembly. Certified scope: manufacture of seat frame assemblies.

What we make

Three product families, all built around the same core: bend the wire or tube, cut and stamp the sheet-metal brackets, then weld it into one assembly the seat maker can bolt straight in.

Seat cushion foam wire frame assembly

Seat cushion wire frame assemblies

Our core product — the bent-wire and sheet-metal frame that carries the cushion foam and the occupant. Example part Y0494632B rear cushion wire frame assembly.

EPP frame assembly with welded wire brackets

EPP frame assemblies

Wire frames designed around EPP foam (expanded polypropylene — light, impact-absorbing). Example part Y0767438 LH EPP frame assembly.

Bent tube components for seat frames

Tube & wire sub-assemblies, brackets

Rear tubes, upright tubes, cushion support tubes, necked-down tube assemblies, adjuster links and stamped brackets — supplied on their own or welded into the assembly above.

The process chain, in-house

Everything from raw wire and tube to a welded, inspected assembly happens on our floor. Surface treatment (e-coat, zinc plating) is the one step we place with qualified outside processors — and we say so up front rather than implying we plate in-house.

Quality you can audit

Welding is a special process — you cannot see a bad weld from the outside. So we measure it. Our quality department issues weld penetration reports with sectioned and etched samples, part number by part number, and they are available on request for the parts we quote you.

The management system is certified to IATF 16949:2016, certificate no. 50052626 IATF16 (IATF registration 0516042, USI GTK3KY), scope manufacture of seat frame assemblies, design excluded. Certificates are issued in both Chinese and English.

How we quote — no black box

A quotation from us is three separate lines, not one lump sum, so you can see exactly what you are paying for and challenge any of it:

  • Part processing cost Material, bending, laser cutting and welding labour
  • Tooling amortisation Fixture and gauge cost divided by the volume you commit to — quoted as its own line, with the divisor stated
  • Outsourced surface treatment E-coat or zinc plating, passed through at the processor's rate

Send a drawing (PDF, STEP, DWG or DXF) with your annual volume and SOP date. Our overseas business desk replies within 3 working days — either with a quotation or with the specific questions we need answered to make one.
