What is Mechanical Processing?

Mechanical processing is the process of employing technical methods and specialized machinery and equipment to form, transform, cut, and join metals and other materials according to required technical designs. The objective is to produce parts, components, machine sub-assemblies, or finished products that serve industrial production.

In the context of the Fourth Industrial Revolution (Industry 4.0), mechanical processing acts as the "backbone" of the manufacturing industry, serving as the link between creative design and physical products. Without high-quality mechanical processing, industries such as automotive, aerospace, construction, electronics, and energy would be unable to advance. Particularly, with the trends of automation and smart manufacturing, the requirements for precision, speed, and consistency in mechanical processing are becoming increasingly stringent, requiring enterprises to continuously innovate technology and enhance service quality.

In Vietnam, mechanical processing is one of the key industrial sectors, significantly contributing to GDP growth and providing employment for millions of laborers. The development of the mechanical processing industry not only serves domestic demand but also aims for export, positioning Vietnam on the global supply chain map.

Common types of mechanical processing include:

Mechanical Machining: Turning, milling, planing, drilling, and grinding – using cutting tools to remove excess material.
Thermal Processing: Welding, spot welding, TIG/MIG welding, and plasma cutting – joining or cutting metals using high temperatures.
Pressure Processing: Stamping, bending, drawing, and pressing – deforming metal through mechanical force.
CNC Machining: Utilizing Computer Numerical Control (CNC) for high-precision machining.
Laser Processing: Cutting and engraving metals using high-power laser beams.
Surface Treatment: Plating, painting, coating, and polishing – improving aesthetics and corrosion resistance.
