Customizable color settings,
It can effectively enhance the anti-corrosion, anti-oxidation, and increase the strength of the material, and can also achieve the effect of improving the appearance.
Custom metal enclosures process
According to different product requirements and materials, we use metal stamping, CNC punching, laser cutting, water jet cutting and other methods.
We cold work and bend the metal plate through processes such as sheet metal bender, so that the metal plate can be quickly deformed into the shape we need. This is a very important process and it is necessary to understand sheet metal design guidelines.
Usually we rely on stamping to make some special designs such as: cooling vents, shutters, and other special designs, suitable for stamping and forming of large-scale products, with the advantages of high efficiency and low cost.
The metal plate is deformed by external force. After forming, the thickness of the material will become thinner. Generally, the reinforcing ribs and ribs on the product are increased by stretching to enhance the structural rigidity and stress strength of the product. You can also add bumpy logo graphics.
Supro MFG has a strong internal welding production line to provide welding support for sheet metal workshop products, including: arc welding, gas shielded welding, robotic welding, precision mold welding, etc. We have rich experience and professional expertise in sheet metal welding. The technical team can easily deal with the welding work of various structures and materials.
Riveting and welding are essential processes for customizing sheet metal cabinets. Most sheet metal cabinets need to be assembled with many accessories. We have a large reserve warehouse for fasteners and hinges, and can accept any special custom or imperial Fastener assembly to meet all the needs of users is our goal.
According to the harsh application environment of different products, we can carry out surface treatment to enhance the characteristics of metal materials. For example, powder coating can be used for outdoor chassis to enhance corrosion resistance and increase aesthetics. The aluminum sheet metal chassis can be anodized to enhance surface hardness and customizable in beautiful colors. Kitchen cabinets can be brushed or painted to improve surface aesthetics and corrosion resistance. For more surface treatment options, please click here.
In order to ensure that the product can meet the harsh application environment, we can conduct simulation tests on the product,
