Common Casting Processes of Dongguan Sanhe Machinery Co., Ltd
1. Metal mold casting, also known as hard mold casting, is a casting method that pours liquid metal into the metal mold to obtain castings. Molds are made of metal and can be reused multiple times (hundreds to thousands of times). The castings currently produced by metal mold casting still have certain limitations in terms of weight and shape, such as being limited to simple shaped castings for ferrous metals; The weight of the casting should not be too large; There are also limitations on wall thickness, and smaller castings cannot be produced.
2. Centrifugal casting is a technology and method that injects liquid metal into a high-speed rotating mold, causing the metal liquid to undergo centrifugal motion to fill the mold and form a casting. Due to centrifugal motion, liquid metal can fill the mold well radially and form a free surface of the casting; A cylindrical inner hole can be obtained without the use of a core; Helps to eliminate gases and inclusions in liquid metals; Affects the crystallization process of metals, thereby improving the mechanical and physical properties of castings.
3. Vacuum suction casting is a casting method that creates a vacuum in the mold cavity, sucks metal from bottom to top into the mold cavity, and solidifies into shape.
4. Gravity casting refers to the process of injecting molten metal into a mold under the influence of Earth's gravity, also known as gravity casting. Generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc; Narrowly defined gravity casting mainly refers to metal mold casting.
