2) Strength The ability of the sand to resist external force damage is called strength. 4) Plasticity refers to the ability of the molding sand to deform under the action of external force and to maintain the existing shape completely after removing the external force.. If the fire resistance of the molding material is poor, the casting is prone to sticky sand. 3) Fire resistance High-temperature metal liquids have a strong thermal effect on the mold after pouring, so the molding sand must have the ability to resist high-temperature thermal effects, that is, fire resistance.

If the metal equipment is used for a long time, it will produce some rust, dirt and the like. The corrosion and scale inhibitor can not only effectively remove them, but also effectively prevent it from rusting again. What kind of application does it have in casting? What? 1. It chooses pure carbon-containing graphitized material itself to reduce excessive impurities in pig iron, which can reduce the production cost of castings.

Why sand casting is still so hot in our industrial application. Let's talk to you about the special features of our sand casting by the editors of our specialty manufacturers. Why is it so popular? First of all, his wide scope of application, as small as a few grams, as large as hundreds of tons of castings can be achieved by our sand casting. Non-ferrous castings have higher specific strength and specific stiffness, good shock absorption and excellent cutting performance. Parts used in the aviation industry, instruments, radio technology and transportation industries.

Gravity casting mainly refers to the process in which the molten metal is effectively injected into the mold under the influence of the gravity of the earth. It is also called gravity casting in the process of use. Gravity casting includes sand copper coupling Manufacturers casting and metal casting. Casting, investment casting (mold casting), lost foam casting, mud casting, etc., narrow sense gravity casting mainly refers to metal casting. Non-ferrous castings have higher specific strength and specific stiffness, good shock absorption and excellent cutting performance.
