CNC Milling
A Machining Process That Uses Rotary Cutters to Remove Material from a Workpiece, Suitable for Flat or Irregularly Shaped Parts Made of Various Materials Such as Metals, Plastics, And Woods. Advantages: Versatility in Creating Complex Shapes, High Precision, Repeatability, And Efficiency in Mass Production.
Stamping process
A processing method that uses a mold to process metal sheets or other materials on a punching machine. In the stamping process, the metal plate is pressed, stretched, bent, scaled and other operations through the mold to achieve the precise control of the shape and size of the workpiece
Advantages:High efficiency, high precision and low cost, and is widely used in automobile manufacturing, electronic products, home appliances and other industries
Sheet metal bending
A commonly used metal processing process, used to bend sheet metal into the desired shape according to the design requirements. This process is mainly used in the manufacture of various metal components, parts and products, such as boxes, shells, frames and so on.
Advantages:low cost, high efficiency and high machining accuracy
Die casting
A metal processing process in which liquid metal or alloy is injected into a mold and solidified by high pressure. Die casting is a commonly used metal casting method, which is suitable for the production of metal parts with complex shapes and high precision.
Advantages:High production efficiency, high finished product precision and good surface quality
