Industries We Serve
We support rolling stock tier suppliers, rail equipment manufacturers, maintenance and overhaul providers, and infrastructure contractors. Our team manufactures the components inside bogie hardware, door systems, braking assemblies, and electrical enclosures, producing each part to the drawing, tolerance, and inspection standard specified. High-speed rail programs sit within this scope alongside conventional rail and light rail applications.
Manufacturing Capabilities for Railway
Yijin Solution combines CNC machining, CNC turning, sheet metal fabrication, custom fastener production, and surface finishing for railway projects. Managing these processes through one supplier reduces drawing-control overhead, inspection inconsistencies, and lead time exposure. Our team supports prototyping, qualification builds, and repeat production using steel, aluminum, stainless steel, and bearing alloys.
CNC Machining
CNC machining produces milled brackets, mounting plates, housings, and wear components in carbon steel, HSLA, stainless steel, and aluminum. Machined features hold plus or minus 0.01 mm on suitable geometry, standard work at plus or minus 0.05 mm, and milled parts within 3000 mm.
CNC Turning and Swiss Turning
CNC turning and Swiss turning produce pins, bushings, spacers, and shafts across 278 lathes and more than 80 Swiss-type lathes. Swiss turning holds the guide bushing close to the cut, which keeps slender hardware straight at turned diameters within 400 mm.
Sheet Metal Fabrication
Sheet metal fabrication covers formed panels, interior hardware, cable trays, and enclosures cut across 30 laser cutting machines. Precision tolerance reaches plus or minus 0.10 mm, standard work sits at plus or minus 0.30 mm, and sheet sizes run within 2440 mm by 1220 mm.
Custom Fasteners
Custom fasteners are cold-headed and secondary-threaded across 150 cold-heading machines, to a plus or minus 0.02 mm on specifications up to M24. Producing fasteners in-house keeps them on the schedule of the parts they secure.
Surface Finishing
Surface finishing options include passivation, anodizing, zinc plating, powder coating, and chromate conversion, selected against the corrosion exposure expected. Salt spray testing sits among the 281 inspection instruments on site, so finish performance is verified rather than assumed.
Parts We Make for Railway
We manufacture custom railway parts from customer drawings and 3D CAD files. Each part is produced to the specified material, tolerance, finish, and inspection requirements.
- Structural brackets and mounting plates in carbon steel and aluminum, milled for vibration loading.
- Equipment housings and enclosures machined or fabricated in aluminum with thin wall sections.
- Cable trays and cover panels formed and punched from sheet steel.
- Interior and cabin hardware components are formed in aluminum sheet where flatness and finish matter.
- Machined fittings and connectors in stainless steel with controlled sealing face finishes.
- Hydraulic and pneumatic fittings turned in stainless steel.
- Precision pins and shafts Swiss-turned at small diameters and held straight.
- Bushings and spacers in bronze and stainless steel for bearing surfaces.
- Custom fasteners cold-headed to plus or minus 0.02 mm with secondary threading.
- Wear plates and liners in hardened steel as replaceable contact surfaces.
- Door, latch, and trim hardware components machined in aluminum and finished for wear.
- Test fixtures, jigs, and check gauges machined as tooling for assembly verification.
From Idea to Production
At Yijin Solution, every railway project starts with a free DFM review, where tolerances, datums, and material choices are settled before the first cut. Prototyping typically takes 3 to 7 days, and design revisions are absorbed within the same fixturing rather than restarting qualification. Production scales up in the same facility under the same quality system, so parts do not requalify at a second supplier. Inspection records and material certificates travel with the parts, and our new product development services extend the same route into early concept work.
Why Railway Manufacturers Choose Yijin
Precision and Quality
Yijin Solution machines components to plus or minus 0.01 mm on suitable features under an ISO 9001-certified quality system, with Zeiss CMM dimensional reports available on request.
Prototyping to Production
Prototyping typically runs 3 to 7 days and moves into production in the same facility, with no requalification at a second supplier.
Material Breadth
Carbon steel, HSLA and alloy steels, stainless 304 and 316, aluminum grades, bronze bearing alloys, and engineering plastics run across machining and fabrication.
Order Any Size
Order quantities run from single prototypes through repeat production runs, backed by 887 pieces of production equipment, including 150 cold heading machines.
Cost-Effective
Direct factory pricing applies, and a free DFM review at the quote stage removes tolerance rework before cutting starts.

Railway Parts Manufacturer FAQs
Which certifications does Yijin hold for railway work?
The factory holds four certifications: ISO 9001, ISO 14001, ISO 13485, and IATF 16949. IATF 16949 is the transport sector quality system that rail buyers recognize, providing documented inspection and lot traceability on every order. ISO 22163 is not among the certifications held; the standard adds configuration management and supply chain controls for programs that require it at the supplier level.
What is ISO 22163 and does a component supplier need it?
ISO 22163 is the rail sector quality management standard published by ISO and administered through the IRIS Certification scheme run by UNIFE. It adopts the ISO 9001 structure and adds rail-specific requirements, so an ISO 9001 system is the base layer buyers assess. Some rolling stock programs require ISO 22163 at the supplier level, so confirming the requirement early avoids a late substitution.
Does EN 45545 fire performance apply to machined railway parts?
EN 45545-2 sets reaction-to-fire requirements for materials and products used on rail vehicles, with hazard levels drawn from EN 45545-1. Bare machined metal components are rarely the item under assessment, while coatings, plastics, and non-metallic parts usually are. Stating the hazard level and requirement number at RFQ lets material and finish selection match the vehicle category.
What tolerances are achievable on railway components?
Machined features reach plus or minus 0.01 mm where geometry and material allow, with standard machined work at plus or minus 0.05 mm. Sheet metal precision work reaches plus or minus 0.10 mm, and cold-headed fasteners hold plus or minus 0.02 mm. Achievable tolerance depends on feature type, part geometry, and the inspection method used to verify it.
Are material certificates and first article inspection reports available?
Material certificates and first article inspection reports are available on request. A material certificate records grade, heat number, and composition, while a first article report records measured values against every drawing dimension. Verification runs on 281 inspection instruments, including Zeiss CMMs and salt spray testers.
What lead times apply to railway prototypes and production runs?
Prototyping typically runs 3 to 7 days, with production following in the same facility. Lead time moves with part complexity, the number of setups, finishing scope, and the depth of inspection requested. Quoted lead times are confirmed against current load at the quotation stage rather than fixed in advance.
