Materials

Sheet metal materials

Choose rivet materials according to the material of the sheet metal. For example, aluminum alloy sheet metal can use aluminum alloy rivets to avoid electrochemical corrosion between different metals; stainless steel sheet metal is suitable for stainless steel rivets to ensure the strength and corrosion resistance of the connection. For some projects that require weight, such as the aerospace field, titanium alloy rivets can be used to ensure strength while achieving light weight.

Working environment

If the sheet metal project is in a corrosive environment such as humidity, acid, and alkali, rivets with good corrosion resistance should be selected, such as stainless steel or rivets with special surface treatment (such as galvanizing or nickel plating). Sheet metal parts working in high-temperature environments need to choose high-temperature resistant rivet materials, such as high-temperature alloy rivets.

Size

State-of-the-art fabrication processes to optimize speed and accuracy

Diameter: The rivet diameter should be determined according to the thickness of the sheet metal and the connection strength requirements. Generally speaking, the thicker the sheet metal, the larger the rivet diameter required. Usually, the rivet diameter should be slightly larger than 1.5 times the thickness of the sheet metal to ensure sufficient connection strength. For example, for a 2mm thick sheet metal, a rivet with a diameter of 3-4mm can be selected.
Length: The rivet length should ensure that the rivet hole can be completely filled after riveting and that a suitable riveting shape. Its length is generally the thickness of the sheet metal plus the length of the rivet head. The rivet head length is usually 1.5 – 2 times the rivet diameter. For example, for a 3mm thick sheet metal, a 4mm diameter rivet is used, and its length should be about 3 + (4×1.5) = 9mm.

FAQ's about sheet metal fabrication service

What types of sheet metal materials can be used in fabrication?

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.

What sheet metal fabrication processes do you offer?

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**.

How do you ensure the quality of fabricated sheet metal parts?

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.

What is the lead time for sheet metal fabrication projects?

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.
