[China Aluminum Industry Network] Principle of Casting:
Casting is a process in which a metal is smelted into a liquid that meets certain requirements and poured into a mold, and after cooling and solidification and finishing treatment, a casting having a predetermined shape, size, and performance is obtained. Casting blanks reduce the cost and reduce the time to a certain extent because they are almost shaped and reach the goal of free machining or a small amount of processing.
Casting type:
Ordinary sand casting, including wet sand type, dry sand type and chemical hardening sand type, our company now uses CO2 hardened sodium water glass sand.
Special casting can be divided into special castings using natural mineral sand as the main modeling material (such as investment casting, mud casting, casting workshop shell casting, negative pressure casting, solid casting, ceramic casting, etc.) And special castings (such as metal casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc.) that use metal as the main casting material.
Casting process:
Casting (making the liquid metal a container for solid castings) is prepared according to the materials used. It can be classified into sand type, metal type, ceramic type, clay type, graphite type, etc. According to the number of uses, it can be divided into disposable type, semi-longer For the type and the longer type, the pros and cons of the mold preparation are the main factors that affect the quality of the casting.
Foundry metals are melted and poured. Cast metals (cast alloys) mainly consist of cast iron, cast steel, and cast non-ferrous alloys. The Zhengzhou Dingsheng production site pours castings on site for processing and inspection. Castings include removal of cores and foreign materials on the surface of the castings, removal of sluice gates, grinding of burrs and kerfs, and heat treatment, shaping, rust-proofing, and roughing. At present, the company that produces crusher parts in China is Zhengzhou Dingsheng Engineering Technology Co., Ltd., Zhengzhou Dingsheng has achieved remarkable results in the industry, crusher parts selected Zhengzhou heyday.
