Precision Sheet Metal Fabrication Process

There are many types of materials available for sheet metal customization: cold rolled sheet (SPCC), hot rolled sheet (SPHC), electro-galvanized sheet (SECC), hot dip galvanized sheet (SGCC), stainless steel: such as SUS301 and SUS304, copper and copper alloys, aluminum and aluminum alloys: such as 6061, 6063 aluminum alloys, and other materials: including tinplate (SPTE).
We can also source many custom materials on request. Contact Violet@fuleimetal.com to discuss the options.

We provide the following processing services:
1. **Drawing design**.
2. **Laser cutting**, processing accuracy can reach ±0.1mm.
3. **Bending**.
4. **Forming**: Other forming processes besides bending, such as using molds on ordinary punching machines or other equipment to deform the workpiece, including stretching, rib pressing, convex bulge, etc.
5. **Welding forming: Commonly used welding methods include argon arc welding, butt welding, carbon dioxide welding, etc. The welding gap is generally 0.5-0.8mm, and the weld is uniform and smooth.
6. **Surface treatment**: electrostatic powder spraying, liquid paint, electroplating, surface oxidation, surface brushing
7. **Assembly**: Screws, rivets and other connection methods may be used.
8. **Packaging and shipment**.

To ensure the quality of sheet metal parts, we strictly implement the process flow, establish a quality management system, and strengthen quality inspection: full inspection of the first piece, including inspection of the size, expansion, etc., sampling inspection of finished products, and comprehensive inspection of the appearance. If unqualified, timely adjustment and re-inspection.

The lead time for sheet metal fabrication projects varies based on multiple factors, such as project complexity, material availability, production capacity, and manufacturing processes.
In general, simple sheet metal fabrication projects may have a lead time of a few days to a week or so. Complex projects or those with special requirements can take two to four weeks or even longer. Prototype projects usually take 2-5 days if in-stock materials are used.
