Laser Cutting

Laser cutting is a high-precision machining technique that uses a laser beam as the cutting tool. By focusing the laser generated from a laser source, the high energy of the laser is concentrated on the material surface, causing the material to rapidly heat up, melt, or vaporize, thus achieving processes such as cutting, drilling, and engraving.

Plasma Cutting

Plasma cutting is a processing technology that uses a high-temperature plasma arc to cut conductive materials, such as metals. By ionizing a gas (such as nitrogen, oxygen, air, or argon), a high-temperature plasma arc is formed, and the resulting high-temperature plasma stream quickly melts and blows away the material in the cutting area, achieving the cutting process.

Oxy-Fuel Cutting

Oxy-fuel cutting is a traditional thermal cutting process that uses a high-temperature flame to cut metals. It works by mixing oxygen with a fuel gas (such as acetylene, propane, etc.), and the heat generated by the combustion is used to cut the metal. This technique is commonly used for cutting thicker steel, especially carbon steel and low-alloy steel.

Metal Bending

Metal Bending is a process in which metal materials undergo plastic deformation under the action of external force, thereby changing their shape. Typically, metal bending is used to process metal sheets or metal strips into specific geometric shapes, such as U-shapes, V-shapes, or other complex forms.

Metal Welding

Metal welding is a manufacturing process that joins two or more pieces of metal into a single unit through heating, applying pressure, or a combination of both.MIG, TIG, spot, laser, and arc welding are commonly used to meet different strength, precision, and production requirements.
