SJ-MFG’s sheet metal fabrication capabilities including laser cutting, bending, stamping, punching, welding, riveting, etc. We can process materials such as stainless steel, aluminum, steel and copper, and also offer a one-stop service for surface treatment.
Laser cutting is a process that uses a high-energy-density laser beam to irradiate the workpiece, causing it to reach its melting point or boiling point. Then, by using gas spraying, the melted or vaporized materials are removed, thereby achieving the cutting operation. We offer precise laser cutting and sheet cutting services for various metals.
Bending - The metal sheet material is pressed by the upper or lower die of the bending machine, ensure that the upper and lower molds are tightly in contact with the sheet material., thereby forming various geometric shapes, such as V-shape.
Stamping is a forming processing method that uses a press machine and molds to apply external force to metal sheets, thereby obtaining the required shape and size of the workpiece.
The principle of punching processing is to use the punch to impact the material, causing holes to form on the material, thereby achieving the processing goal.
The essence of welding is to join two separate objects together by heating or applying pressure, or using both methods simultaneously.
Riveting is the process of connecting two or more workpieces using rivets. The ends of the rivets are flattened to form a strong connection.
Lightweight, high strength, corrosion-resistant, easy to shape, low processing cost, suitable for various complex structures.
SJ-MFG offers a wide range of surface treatment options, which are applied to the surface treatment of 5 axis CNC parts. The main purpose is to meet specific functional requirements, enhance the appearance color, and improve the chemical and corrosion resistance of the part surface.
A protective oxide layer is formed on the surface of metal products, which is corrosion-resistant, wear-resistant, has a variety of colors and a beautiful appearance. It is most commonly used for aluminum alloy materials.
Using the impact effect of high-speed sand flow to clean and roughen the surface of the parts, a certain degree of cleanliness and different roughness can be achieved, and is applicable to both metal and plastic materials.
Heated in a high-concentration chemical solution, it forms a dense protective film, which is used to enhance the corrosion resistance, improve the appearance and minimize light reflection. It is commonly used for steel and stainless steel materials.
Enable the powder paint to adhere to the parts, forming a hard coating film on the surface. The coating thickness is uniform and it is wear-resistant. It is commonly used for metal parts.
Liquid paint is sprayed onto the surface of the parts by compressed air. It is widely used for surface coating of products such as automobiles and electronics, and is applicable to both metal and plastic materials.
Coating a layer of another metal on the surface of the metal part, such as nickel, chrome, gold, zinc plating etc, it is corrosion-resistant, wear-resistant and has a beautiful appearance. It is suitable for metal parts.
Based on the surface treatment with chemical plating solution, the parts are immersed in the plating solution to form a metal film, no need for electricity. Suitable for metals and a few plastic materials (ABS, PP, PC).
Using the charged particles in the solution to form a uniform coating on the surface of the parts. Suitable for metal parts.
Reduce the surface roughness of the parts and achieve a shiny, smooth and mirror-like surface effect. Applicable to metal parts and plastic parts.
By grinding the surface of the parts to create lines, a fine and lustrous effect is achieved. Applicable to metal parts.
Using high-energy-density lasers to irradiate specific areas of the parts, special marks are left. Applicable to metal and plastic parts
Press the screen-printed plates with graphics and text onto the surface of the parts, and offer a wide range of color options. Suitable for metal and plastic parts.
