1. The filling of metal liquid is stable,and the speed is controllable, and the gas and oxidation are reduced, which can improve the casting quality.
2. Product repeatability is good and high pass rate.
3. The fluidity of the molten metal is good, which is beneficial to the casting of thin-walled castings with clear outline and smooth surface.
4. The pouring gate is small,and the processing allowance is small, and it has no riser, which occupy about 10%-25% of the total weight.
5. Casting dimension and weight are not limited by the machine.
6. Other materials such as sand core can be placed in the mold cavity to produce castings with complex internal structures.
7. Equipment is easy to mechanize and automate.
