Laser Cutting
CO₂ and fiber laser systems for burr-free edges and ±0.05 mm dimensional accuracy on steel, aluminium, and copper.
Precision machining utilizes computer numerical control (CNC) machines to cut, mill, and drill metal or non-metal materials. It enables the production of complex surfaces and high-precision parts with a high degree of automation, accuracy, and efficiency.

Precision sheet metal products are fabricated components produced from thin metal sheets — typically 0.5 mm to 20 mm thick — through controlled manufacturing processes including laser cutting, CNC punching, press braking, welding, and surface finishing. The term "precision" denotes tight dimensional tolerances (commonly ±0.05 mm to ±0.1 mm), consistent repeatability, and clean surface quality that downstream assembly processes depend on.
At Zhejiang Jiafeng, we manufacture precision sheet metal products using 5-axis machining centres, CNC lathes, and multi-axis milling equipment, enabling complex geometries that conventional fabrication cannot achieve. Every product leaves our factory certified and ready for integration.
Choosing the right material is the single most important decision in precision sheet metal fabrication. The table below compares the most common materials we process, helping you match mechanical requirements to your application.
| Material | Tensile Strength | Corrosion Resistance | Weight | Typical Finish | Best For |
|---|---|---|---|---|---|
| Stainless Steel 304 | 515–720 MPa | Excellent | Heavy | Brushed, Polished, Passivated | Food equipment, medical, enclosures |
| Stainless Steel 316 | 485–690 MPa | Superior (Mo added) | Heavy | Electropolished, Brushed | Marine, chemical, pharmaceutical |
| Cold-Rolled Steel (SPCC) | 270–370 MPa | Low (needs coating) | Heavy | Powder coat, Painting, Galvanising | Structural panels, chassis, brackets |
| Galvanised Steel (GI) | 270–370 MPa | Good | Heavy | Powder coat, Primer | Outdoor enclosures, HVAC components |
| Aluminium 5052 | 195–260 MPa | Very Good | Light | Anodising, Powder coat | Aerospace panels, electronics, transport |
| Aluminium 6061 | 276–310 MPa | Good | Light | Anodising, Clear coat | Machined structural parts, heat sinks |
| Copper C110 | 220–250 MPa | Moderate | Heavy | Tin plating, Passivation | Bus bars, electrical contacts, heat exchangers |
* Values are indicative ranges; final specs depend on thickness, temper, and processing method.
