Chiheng provides precision sheet metal fabrication including laser cutting, bending, welding and finishing. Tolerances ±0.05 mm. Prototype to mass production. Get a quote in 24 hours.
From raw sheet to finished part, every process is handled in-house. No subcontracting. No quality surprises. Just precise, consistent results at every stage of production.
We use both fiber and CO₂ laser systems to cut sheet metal with exceptional speed and edge quality. Our equipment handles steel up to 20 mm, stainless steel up to 12 mm, and aluminum up to 10 mm, delivering cut accuracy of ±0.1 mm with minimal heat-affected zones and burr-free edges ready for bending or welding.
Our CNC press brakes deliver repeatable, high-precision bends across a wide range of material thicknesses and profiles. Using tooling libraries matched to your drawing specifications, we form complex brackets, enclosures, channels, and flanges with consistent angular accuracy — even across large production runs.
For high-volume production runs where speed and consistency are critical, our stamping and CNC turret punching lines deliver. We produce precision holes, slots, louvers, embosses, and custom cutout patterns with tight repeat tolerances. Custom tooling is developed in-house, reducing per-part costs significantly at scale.
Our certified welders perform TIG, MIG, and spot welding across steel, stainless steel, and aluminum assemblies. We work to drawing-specified weld symbols and seam requirements, with post-weld grinding and finishing available for cosmetic surfaces. Full sub-assembly — including hardware installation and component integration — is offered as part of our turnkey service.
The right surface finish protects your parts and meets the aesthetic or functional requirements of your end application. We offer a full range of finishing processes in-house and through certified partner facilities, applied after fabrication and inspection to ensure dimensional integrity is maintained throughout.
We press-in threaded fasteners, standoffs, PEM nuts, and rivets as part of the standard fabrication flow — no need for secondary operations on your end. All hardware is sourced to your specification and installed with controlled press force to ensure proper pull-out and torque resistance. Your parts arrive ready for direct integration into your final product.
Choosing the right material is as critical as the fabrication process itself. At Chiheng, our precision sheet metal fabrication capabilities span a wide range of metals — from lightweight aluminum alloys to high-strength stainless steel and carbon steel. Each material is selected based on your application’s mechanical requirements, corrosion environment, and surface finish needs. Below is a quick-reference guide to help you specify the right material for your custom sheet metal parts.
| Material | Machinable Thickness Range | Common Applications | Recommended Surface Finishes |
|---|---|---|---|
| Aluminum (5052 / 6061) | 0.5 mm – 6.0 mm | Enclosures, brackets, aerospace panels, heat sinks | Anodizing, powder coating, chromate conversion |
| Stainless Steel (304 / 316) | 0.5 mm – 4.0 mm | Medical devices, food equipment, marine hardware, structural frames | Brushed finish, electropolishing, passivation |
| Carbon Steel (Q235 / SPCC) | 0.8 mm – 6.0 mm | Automotive chassis parts, industrial frames, general structural components | Powder coating, galvanizing, painting, black oxide |
| Galvanized Steel | 0.5 mm – 3.0 mm | HVAC ducting, outdoor enclosures, electrical cabinets | Powder coating, painting |
| Copper (C101 / C110) | 0.3 mm – 3.0 mm | Electrical bus bars, heat exchangers, RF shielding components | Tin plating, nickel plating, clear lacquer |
| Brass (C260 / C360) | 0.3 mm – 3.0 mm | Decorative panels, connectors, precision instrument housings | Nickel plating, chrome plating, clear lacquer |
| Cold-Rolled Steel (CRS) | 0.5 mm – 3.2 mm | Precision enclosures, automotive body panels, appliance housings | E-coating, powder coating, zinc plating |
Not sure which material fits your design?
Our engineering team reviews every inquiry with a DFM (Design for Manufacturability) assessment — free of charge. Whether you need aluminum sheet metal fabrication for a lightweight aerospace bracket or stainless steel sheet metal fabrication for a corrosion-resistant medical enclosure, we’ll recommend the optimal material-process combination to meet your performance specs and budget.
Numbers speak louder than claims. Here’s what sets our precision sheet metal fabrication apart from generic suppliers.
Every order includes a complimentary drawing feasibility review before production begins — we assess manufacturability, flag potential issues, and provide recommendations on critical technical challenges upfront at no extra cost.
CMM dimensional inspection on every batch. Full reports available on request. We do not ship parts outside agreed tolerances — period.
Same precision tooling from a 1-piece prototype through 10,000-unit production runs — no tolerance drift, no re-tooling surprises between stages.
One point of contact from quotation through final delivery. Bilingual (English/Chinese) support and weekly production updates are standard — not an upgrade.
Aluminum, stainless steel, carbon steel and more — paired with laser cutting, bending, welding, and a full range of surface finishing options.

From prototype labs to high-volume production lines, Chiheng supplies precision sheet metal fabrication services to manufacturers and engineers across industries where dimensional accuracy, material integrity, and on-time delivery are non-negotiable. Our process capabilities and material range allow us to meet the specific requirements of each sector — without compromise.
Sheet metal enclosures, brackets, and chassis for consumer electronics, industrial control panels, and electrical distribution equipment. We fabricate to tight tolerances with EMI shielding and grounding requirements in mind.
Structural brackets, mounting plates, body reinforcement components, and custom tooling fixtures for automotive OEMs and Tier 1–2 suppliers. High repeatability across large production batches is our standard — not a premium.
Cleanroom-compatible fabrication of stainless steel panels, housings, and structural frames for medical devices, diagnostic equipment, and laboratory instruments. Smooth weld finishing and electropolishing available to meet hygiene standards.
Lightweight structural components and precision-formed parts manufactured to strict dimensional specifications. We work with aerospace-grade aluminum and titanium sheet where required, with full material traceability documentation.
Custom fabricated panels, frames, guards, and enclosures for industrial automation systems, conveyor equipment, and heavy machinery. We handle both structural and cosmetic requirements within a single production workflow.
Precision-formed sheet metal components for server racks, network enclosures, antenna mounting systems, and cable management infrastructure. Tight hole-pattern tolerances ensure drop-in compatibility with standard equipment.
