How to process metal Fabrication?

May 30, 2018

Sheet metal fabrication, which refer to Fabricated metal products , Metal fabrication tools, metal pipes, etc. of various specifications and shapes made of metal materials.

 

Materials for Custom metal fabrication  : steel and nonferrous metals (or non-ferrous metals).

Parts made of various metals.

Steel: iron alloy with a carbon content of 2% ~ 4.3% is cast iron with a carbon content of 0.03% ~ 2% iron alloy as steel.In fe-c alloy, a variety of appropriate alloy elements are added to improve the strength, hardness, abrasion resistance and corrosion resistance of steel.

 

 1. Causes of metal corrosion.

Corrosion of Steel sheet metal has two major types: chemical corrosion and electrochemical corrosion.

 (1) chemical corrosion

 (2) electrochemical corrosion.

 

Treatment process

The commonly used anti-rust methods of metal parts include oxidation method, phosphating method, electroplating method, spraying plastic coating method, brush coating anti-rust coating method and so on.

1) anticorrosive and anti-rust treatment: black and boiled blue treatment is also called phosphating treatment, so that metal parts have the properties of corrosion resistance and rust prevention.All kinds of steel parts can be coated with anti-rust paint.First, apply the red red anti-rust paint (primer) on the surface of the parts, then apply a layer of gray anti-rust paint (paint), and pay attention to the surface of the parts can not be painted.

2) add hard treatment: increase the hardness of metal parts: 1. Increase the surface hardness of metal parts by using the surface carburizing, and the surface color will be darker after carburizing;2. Hardening treatment can increase hardness;3. Vacuum heat treatment improves the overall hardness.


In the anti-rust work of metal parts, the method of coating anti-rust grease is simple and practical.Finished products sold a wide variety of antirust oil, rust-proof oil are so common, antirust grease, rust, lubrication and grease, gas phase corrosion inhibitor, can strip plastic and so on, can according to the requirements of the accessories of different varieties and different protection to choose to use.

 

The processing technology

Machining, stamping, precision casting, powder metallurgy, metal injection molding, laser machining, electrical discharge machining, ultrasonic machining, electrochemical machining, beams and ultra-high speed machining, etc.Similar to car, milling, forging, casting, grinding, CNC machining, CNC center all belong to machining routine processing.
