Sheet Metal Welding materials
TIG welding, famous for its precision and control, uses a non-consumable tungsten electrode and an inert gas-typically argon-to shield the weld area from contamination. This method produces clean, high-strength welds with minimal spatter, making it especially suitable for thin sections of metals like aluminum, stainless steel, and copper.

Laser welding is characterized by its precision, deep and narrow welds, and the ability to weld a wide range of materials including dissimilar metals, with minimal distortion and a high aspect ratio
Precision: It offers accurate welds with tight tolerances.
Versatility: Suitable for various metal types and thicknesses.
Automation: Easily adaptable for automated and robotic systems

MIG welding, known for its versatility and efficiency, utilizes a continuous wire electrode and shielding gas to join a variety of metals, particularly suitable for thin to medium thicknesses. It's favored for its ease of use, high-speed capabilities, and the quality of welds produced with minimal cleanup required.
High deposition rates: MIG welding deposits weld material quickly, increasing productivity.
Adaptable to automation: It easily integrates with robotic systems for consistent, repetitive tasks.
Excellent for thick materials: MIG welding's high heat input is suitable for welding thick metals

Resistance welding is a highly efficient and versatile process that involves the use of electrical current to generate heat at the contact surfaces of the materials being joined, typically through methods like spot welding, seam welding, and projection welding
This process is characterized by its speed, as it can complete welds in less than a second, and its ability to produce strong welds without the need for filler materials or shielding gases

Laser cutting
- Can cut materials of different hardness, with a wide range of applications
- Before cutting, the contours of multiple parts can be reasonably arranged on a plate to improve material utilization
- The processing process does not rely on molds, and can be cut directly according to the design drawing, with high processing efficiency
- Adopting non-contact processing, there is no need for the tool to contact the workpiece, avoiding dust splashing and oil residue
Bending
- Can process a variety of materials such as metals and plastics, with a wide range of applications
- Can achieve complex bending structures with multiple angles and curvatures, such as U-shaped, Z-shaped, spiral, etc.
- High bending accuracy, the angle and shape of each workpiece can be kept consistent during batch processing
Mould Manufacturing
- Molds can ensure that each batch of products has the same size and meets quality standards
- Suitable for mass production, effectively reducing unit costs and reducing the waste of raw materials
- Can produce products with curved surfaces, micropores, textures, etc. that are difficult to make by hand
- High-quality molds have a long life and are suitable for long-term repeated use
Stamping
- Using automated equipment, a large number of workpieces can be processed per unit time, and the size consistency is good
- Through the reasonable design of layout and precise processing path, the edges and corners of the plate are effectively utilized to reduce the scrap rate, thereby controlling the material cost
- Can process parts with complex shapes such as multiple bends, concave structures, curved surfaces, etc
