Metal parts processing technology introduction

u200b The materials of metal parts: steel and non-ferrous metals (or non-ferrous metals), iron and 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.u200b Treatment process 1) Anti-corrosion and anti-rust treatment: boiling black, boiled blue treatment is also called phosphating treatment, so that metal parts have corrosion resistance and rust resistance. 2) Hardening treatment: The treatment method to increase the hardness of metal parts: 1. To increase the surface hardness of metal parts, use surface carburization, and the surface color will be black after carburization; 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, numerical control processing, CNC numerical control center are all conventional machining processing. Casting Liquid metal is poured into a mold cavity that is compatible with the shape and size of the part, and it is cooled and solidified to obtain a production method of a blank or part. It is usually called liquid metal forming or casting. Process flow: liquid metal→molding→solidification shrinkage→castingsu200b Metal parts processing density tester KW-300A, metal parts, refers to metal blocks, metal rods, metal tubes, etc. of various specifications and shapes made of metal materials Collectively, in the production process, density is one of the very important physical properties, and manufacturers need to strictly control the density index of the product.
