Rail & Transit Metal Stampings
Rolling stock and transit infrastructure run for decades on parts that cannot be serviced easily, so rail hardware is specified for corrosion resistance, vibration survival and repeatable fit. Precision metal stampings fill that role across the vehicle and the wayside: door and gangway hardware, grounding and power busbars, contact strips, cable and connector terminals, EMI shielding for signalling electronics, and the brackets and clips that hold interior and underframe systems in place.
- ISTAMPING produces these parts on 25-110 ton presses with 0.005 mm positioning accuracy from corrosion-resistant stainless, copper, brass, phosphor bronze and galvanized strip between 0.1 and 3.0 mm thick. Burr heights are held to 0.05 mm or less, flatness to 0.03 mm, and dies carry in-die feed and misfeed sensing so long production runs stay stable. Production is controlled under IATF 16949:2016 and ISO 9001 quality systems with lot traceability from incoming coil to finished stamping, and plating for corrosion or contact performance is managed through approved partner lines with salt-spray verification.

01
Door & gangway hardware
The Challenge
Off-spec or inconsistent door & gangway hardware cause assembly failures and field returns.
Our Solution
Stamped latch plates, keepers, guide rollers brackets and hinge components for sliding and plug doors - formed from stainless or galvanized steel with tight flatness control so door mechanisms align and stay aligned through millions of cycles.
02
Grounding & power busbars
The Challenge
Unreliable supply of grounding & power busbars disrupts production schedules.
Our Solution
Stamped and formed copper busbars, shunt contacts and bonding straps for traction power and return-current paths - with selective plating on contact areas for stable, low-resistance joints in vibration-heavy service.
03
Connector and jumper terminals
The Challenge
Off-spec or inconsistent connector and jumper terminals cause assembly failures and field returns.
Our Solution
Precision stamped terminals, splice contacts and jumper strips for train control and inter-car wiring - held to ±0.005 mm positioning so mating faces stay aligned across long vehicle consists.
04
EMI/EMC shielding for signalling
The Challenge
Unreliable supply of emi/emc shielding for signalling disrupts production schedules.
Our Solution
Stamped shield cans and grounding fingers for signalling, communication and passenger information electronics - formed from copper alloys and plated steel with continuous contact geometry.

Brackets, clips and mounting plates
Underframe brackets, cable clips, sensor mounts and interior mounting plates - stamped from galvanized or stainless strip in volume, with burr-free edges for safe handling and coated surfaces for long outdoor service.
Interior & seating hardware
Stamped seat frames clips, panel fasteners and trim retainers for passenger areas - cost-effective galvanized or stainless parts produced at high volume with consistent dimensional accuracy.
Corrosion-Resistant Stamping for Rolling Stock
Rail vehicles are built to serve for 30 years and more, and the stampings inside them are chosen for how they behave after a decade of vibration, humidity and cleaning chemicals. ISTAMPING produces rolling stock stampings from stainless steel, copper alloys and galvanized strip, with the flatness and burr control that keeps mechanisms moving and contacts conducting. Material certification and lot traceability come with every shipment, so fleet maintenance and reorder programs can rely on repeat parts rather than re-engineering.
- Stainless (SUS301/304/316L/430), copper, brass, phosphor bronze and galvanized strip from 0.1 to 3.0 mm
- Burr heights held to ≤0.05 mm and flatness to ≤0.03 mm for mechanism and contact parts
- Corrosion-protection finishes (zinc, passivation, nickel, tin) managed through approved partner lines with salt-spray verification
- Material certification and lot-level traceability on every shipment
High-Volume Stamping for Transit Programs
Transit programs combine large fleet volumes with long, slow-changing production windows, so the cost per part is won in the tool and the press line. Our progressive dies run at up to 300 strokes per minute with in-die sensing to catch mis-feeds before they scrap a coil, and a typical tool delivers 300,000 to 600,000 strokes between refurbishment. Because stamping, die-making and assembly answer to one IATF 16949:2016 quality system, transit builders and their tier suppliers deal with a single accountable partner from certified coil to packed part.
- Progressive dies running up to 300 SPM with in-die feed and misfeed monitoring
- Tooling built in-house with a typical 300,000-600,000 stroke life between refurbishment
- Feed width up to 650 mm and press capacity from 25 to 110 tons for larger brackets and busbars
- IATF 16949:2016 and ISO 9001 certified production with documented process control
