1）What is die casting?
High pressure casting mainly refer to die casting.It is kind of casting method that die casting parts are formed by metal liquid injected in cavity at high speed and pressure.Weiheng Die Casting always provide one-stop die casting service.
2）What is difference between die casting and other casting method?
The main difference are high injection speed and pressure.
3）Three main parts of die casting
Die casting machine,Die casting alloy and Die casting mould.
4）Die casting features
1.High precision and good finishing surface
2.Strength of die casting parts are good
3.Broad range of usage,such as lighting,automobile,furniture,bathroom,electronics,appliance,construction material,hardware,machinery,etc.
4.High production effciency
5.Fast lead time on big volume production.
5) Most common problem for die casting parts
1.Porosity due to air and gas come into cavity together with melted metal at high speed and pressure.
2.Die casting parts are not suitable to welding
3.Cost of die casting machine and tooling are high.
6) Tooling(Die Casting Mould)
Tooling mainly include cavity and core.Melted alloy are injected into cavity and the parts are pull out by eject pin.
7）Die casting procedure
- Spray lubricant
- Injection
- Forming
- Parts pull out by eject pin
- Get parts off mould
8）Seconary machining
- Turning
- Milling
- Tapping and Drilling
9）Surface treatment
- Polishing
- Shot blasting
- Abrasive blasting
- Powder coating
- Electroplating
10) Alloy used for die casting
- Aluminum:Light weight.It is goodful to produce die casting parts with complex geometry and thin wall.Good corrosion resistance and machinery property.
- Zinc:Very easy to die casting.Suitable to small parts and electroplating.Longer life span.
- Magnesium:easy for seconary machining.Most light weight among all of die casting alloy.
- Cooper:High strength and excellent corrosion resistance.The property are very similar to steel.
