Introduction The gas injection can realize the manufacturing process of complex hollow structures inside die castings. During solidification, the process gas is injected into the foundry to
Foundry coating is one of the most important materials in the foundry industry, which has a great impact on the appearance quality and internal quality of castings.
Air permeability is an important performance index of precision casting mold shells. The air permeability of the mold shell comes with a great influence on
The inspection of castings mainly includes dimensional inspection, visual inspection of appearance and surface, chemical composition analysis and mechanical property test.
The solidification feeding mode of precision casting is closely related to the location of the internal sprue.
Wax pattern making is an important process in investment casting production and the primary condition for obtaining high-quality castings.
There are two temperature indicators which will affect the die casting production. One is the pouring temperature and the second is the mold temperature.
Sodium silicate, also known as silicate of soda, it is a dispersion system of sodium silicate, potassium silicate, lithium silicate and quaternary ammonium silicate in water with the coexistence of ions, molecules and colloidal particles of silicate.
Sodium silicate casting is a common processing of precision casting used in the most precision foundries.
Casting is a to transfer the shapeless liquid metal into a shaped solid.
