The materials of metal parts: steel and non-ferrous metals (or non-ferrous metals), steel: the alloy of iron with a carbon content of 2% to 4.3% is cast iron, and the alloy of iron with a carbon content of generally 0.03% to 2% is steel .

Treatment process

  • 1) Anti-corrosion and anti-rust treatment: the black-boiled and blue-boiled treatment is also called phosphating treatment, which makes the metal parts have corrosion resistance and rust resistance.
  • 2) Hardening treatment: The treatment method to increase the hardness of metal parts: 1. Increase the surface hardness of metal parts by using surface carburizing, and the surface color will be black after carburizing; 2. Quenching treatment can increase the hardness; 3. Vacuum heat treatment Improve the overall hardness.

Processing technology

Machining, stamping, precision casting, powder metallurgy, metal injection molding, laser processing, electric discharge processing, ultrasonic processing, electrolytic processing, particle beam processing and ultra-high-speed processing, etc. Similar to turning, milling, forging, casting, grinding, CNC machining, CNC CNC centers are all conventional machining machining.


The liquid metal is poured into a mold cavity suitable for the shape and size of the part, and it is cooled and solidified to obtain the production method of the blank or part, which is usually called liquid metal forming or casting.

Process flow: liquid metal → filling → solidification shrinkage → casting

​Metal parts processing density tester KW-300A, metal parts, refers to the collective name of various specifications and shapes of metal blocks, metal rods, metal tubes, etc. made of metal materials. In the production process, density is very important. One of the physical properties of the product, the manufacturer needs to strictly control the density index of the product.
