Laser Cutting

Product Introduction

Laser Cutting is a high-precision sheet metal fabrication service from Shanghai Hehua Machinery Technology Co., Ltd. We provide custom fiber laser cutting and one-stop metal fabrication for industrial equipment, automotive, rail transit, aerospace, new energy, semiconductor equipment and other demanding applications.

Our integrated service covers laser cutting, CNC punching, CNC bending, welding, riveting, grinding, deburring, straightening, surface treatment and assembly. We support OEM/ODM projects from prototypes and small batches to mass production.

Key Product Advantages

High-Precision Laser Cutting

Advanced fiber laser cutting equipment supports complex contours, holes, slots and customized sheet metal components. Laser cutting dimensional tolerance can reach approximately ±0.03~±0.05 mm depending on material, thickness and part design.

Wide Material Compatibility

We process a broad selection of metal sheets, including:

• Cold rolled steel (SPCC)

• Galvanized steel (SGCC/SECC)

• 304/316 stainless steel

• Aluminum and aluminum alloy

• Copper sheet

• Electrolytic plate

• Galvalume steel

Processable thickness ranges from 0.5 mm to 12 mm.

One-Stop Sheet Metal Fabrication

Beyond Laser Cutting, our capabilities include CNC turret punching, CNC bending, servo bending, forming, rolling, edge curling, riveting, self-clinching, rivet nut installation, TIG/MIG welding, deburring, straightening and assembly.

Multiple Surface Finishes

Available finishing options include powder coating, liquid painting, brushing, polishing, mirror finishing, sandblasting, black oxide, anodizing, electrophoresis, Dacromet, galvanizing, nickel plating, passivation and protective film.

Technical Specifications

Actual tolerance and lead time depend on material, structure, quantity and technical requirements.

OEM/ODM Sheet Metal Fabrication

Our Laser Cutting service is available as part of a complete OEM/ODM sheet metal solution.

Our engineers review customer drawings and optimize designs for manufacturing before production. We can identify bending interference, forming cracks, welding deformation, excessive material use and other potential production risks.
