Customization of sheet metal processing services

We provide metal cutting and bending services to assist customers in sheet metal component processing. Automated cutting processes can ensure high precision and quality of finished components.

laser cutting

A cutting process that can be used to cut metal and non-metallic materials of different material thicknesses. The laser beam that has been guided, shaped, and assembled lays the foundation for this.

Metal punching

A common manufacturing process used to produce large quantities of metal components. It utilizes mechanical operations to shape metal sheets at high speeds through a stamping machine according to mold design trends, in order to achieve the desired shape and size.


It involves applying force to sheet metal parts to change their geometric shape. This force will generate stress on the metal plate that exceeds its yield strength, causing physical deformation of the material without rupture or failure.

Material Selection for Sheet Metal Fabrication


SPCC Steel (non-treated)

SGCC Steel (Galvanized steel)

Stainless Steel



Surface Finishes for Sheet Metal Parts

Surface finishes of metal plate parts refers to the processing and treatment of the surface of metal plate parts to improve their surface quality and performance, increase their corrosion resistance, hardness, wear resistance, and other characteristics, and also improve their aesthetics.

Sheet Metal FAQs

During sheet metal processing, due to the characteristics of materials and processing methods, parts can deform. The solution is to adjust the processing technology and methods, strengthen the support and fixation of materials, and use automated processing equipment to solve the problem.

Welding quality issues in sheet metal processing may lead to issues such as insufficient component strength, porosity, and cracks. The solution is to use high-quality welding materials and equipment, strengthen monitoring and control of the welding process, and ensure that the welding quality meets the requirements.

After the sheet metal processing is completed, surface treatment is required, such as spraying, electroplating, etc. Poor surface treatment may lead to corrosion, oxidation, and other issues. The solution is to use appropriate surface treatment methods and equipment, strictly control the quality of the surface treatment process, and ensure that the surface treatment effect meets the requirements.

During sheet metal processing, dimensional deviations may result in parts being unable to be assembled or poorly assembled. The solution is to strengthen dimensional control and monitoring during the machining process, use high-precision equipment for machining, and compensate for dimensional errors during the machining process.

Quality issues may occur during sheet metal processing, such as surface burrs, cracks, pores, etc. The solution is to strengthen quality control and inspection, use advanced testing equipment and methods, and ensure that the quality of each product meets the requirements.
