Company Profile

Wuxi Henderchan Industrial Co., Ltd.

HDC Manufacturing specializes in custom metal fabrication, including sheet metal fabrication, with a focus on custom hinges, trailer hardware, and welded assemblies. More than just a hinge supplier, we deliver integrated manufacturing solutions by combining laser cutting, press brake bending, stamping, roll forming, welding, CNC machining, assembly, and full-scope surface finishing.
Since: 2015
Specialty: One-stop custom metal fabrication & sheet metal fabrication for hinges, trailer components & welded products

Advanced Features:

In-house tooling & die design – fast design changes; tooling owned by you, free storage, return anytime.
Precision metal & sheet metal fabrication + CNC – laser cutting, press brake bending, stamping, roll forming, welding, knuckle forming, and machining; tolerances up to ±0.01mm.
Full surface finishing – polishing, sandblasting, passivation, powder coating, anodizing, electroplating.
Custom hinge range – piano/continuous, weld-on, flag, lift-off, T-hinge, heavy-duty, and more.
Trailer hardware & accessories – trailer couplers, hitches, cam bar locks, and other custom trailer parts.
Welded assemblies & sheet metal products – trailer ramps, frames, brackets, enclosures, and custom fabricated components.
Low MOQ & fast sampling – 100–500 pcs, samples before mass production.

Precision Metal Fabrication

Precision Secondary Machining

Process capability: Laser cutting, press brake bending, stamping, roll forming, welding, pin insertion, locking, and cutting to length – from your drawings or our custom tooling.
Material selection: Stainless steels, carbon steels, brass, aluminum, and special alloys on request, with material certificates available.
Dimensional control: ±0.10mm on standard features; tighter on critical datums such as hole spacing, knuckle alignment, overall length, and weld position.
Surface quality: As-formed finishes of Ra 3.2–6.3μm – a clean foundation for coating, anodizing, assembly, or welding.
Complex geometries: Continuous knuckles, interlocking leaves, countersinks, weld tabs, and custom hole patterns; also welded structures, brackets, frames, ramps, and enclosures.

Equipment capability: 3-axis to 5-axis CNC used as a secondary operation after stamping, roll forming, welding, and sheet metal fabrication – for features that require tolerances beyond standard fabrication.
Target features: Pin holes, countersinks, mounting faces, end cutouts, special slots, and custom profiles on hinges, trailer parts, welded components, and sheet metal assemblies.
Dimensional accuracy: We hold ±0.01mm on critical datums such as pin hole position, bore diameter, and mounting hole pattern – so your parts mate and function correctly.
Post-fabrication stability: Where required, we stress-relieve components before final machining – so critical dimensions do not move.
Machining finish: We leave your parts with clean, consistent machined surfaces – ready for the next step in your process.

Heat Treatment & Surface Finishing

Quality Control & Inspection

Heat treatment capability: We operate in-house equipment and match cycles to your material – so you get the hardness, strength, ductility, or stress relief you need.
Surface cleaning process: We use shot blasting, deburring, and chemical passivation – so your parts arrive free of scale, burrs, and oxides.
Surface refinement options: We offer polishing, grinding, and AFM – so your pin holes, sliding surfaces, and visible faces are as smooth as you require.
Single-source delivery: You get heat-treated and surface-finished parts from one supplier – ready for your next production step.

In-process monitoring: We check critical dimensions during laser cutting, bending, stamping, roll forming, welding, secondary machining, and heat treatment.
Dimensional & hardness: We use a Zeiss CMM for your datums and Rockwell testing for material properties.
Non-destructive testing: We offer X-ray, dye penetrant, and magnetic particle inspection for internal and surface defects on critical welds and formed sections.
Surface & traceability: We inspect pin fit, opening torque, and finish per your print, and track every part from raw material to ship.
