With the development of modern industry, the demand for precision metal parts is increasing.

These parts are often used in aerospace, automotive, medical equipment and other fields, requiring extremely high dimensional accuracy, surface quality and material.

1. Cutting technology

1.1 CNC Milling   machine

Precision metal parts are often cut by computer numerical control (CNC) machine tools.

CNC technology precisely controls the movement of the tool through pre-programmed instructions to achieve high-precision cutting of metal materials.

The wide application of CNC machine tools has improved the production efficiency and machining accuracy.

Industry Proto-mold   Ltd. has 20 sets of high precision CNC machines.

1.2 Application of superhard tools

The use of superhard tools, such as carbide tools or ceramic tools, can maintain a longer time of tool sharpness during the machining process, improve cutting efficiency, and is suitable for processing metal materials with higher hardness.

2. Precision forming technology

2.1 Precision Casting

Precision casting technology through the precision mold and high temperature metal liquid injection, to achieve high precision forming of metal parts.

This method is suitable for complex shapes and mass-produced parts, while providing excellent surface quality.

2.2 EDM

Edm uses the principle of electric pulse discharge to strip metal from the surface of the Parts to achieve high-precision machining of parts.

This non-contact machining is suitable for metals with higher hardness, such as titanium and stainless steel.

3. Surface treatment technology

3.1 Polishing and grinding

Through polishing and grinding processes, the surface finish and flatness of precision metal parts can be improved.

This is especially important for applications that require the appearance and surface quality of parts.

3.2 Coating technology

Coating technology is often used to improve the corrosion resistance and wear resistance of parts.

For example, the use of chromium or nickel plating process can effectively protect the metal surface and extend the service life of parts.

Industry Proto-mold ltd   can provide all kinds of surface finishing technical services, No MOQ restrictions, 1 piece to do.
