Detailing A Variety Of Casting Characteristics And Differences

1. Casting molten metal pouring process can be divided into gravity die casting and die casting. Gravity casting is under the liquid metal in the Earth's gravity into the casting process, also known as casting. Generalized gravity casting includes sand casting, permanent mold casting, investment casting, clay casting; narrow-casting exclusively metal casting. Refers to pressure casting molten metal in other external force (without gravity) under the action of injection mold process. Broad casting includes die casting machines casting and low pressure casting, centrifugal casting, vacuum casting,; narrow casting exclusively metal pressure casting die casting machine, die cast for short. Asahi precision casting factory has long been engaged in sand and metal mould casting. This casting process is the most commonly used in non-ferrous metal casting, is also relatively lowest prices.


2. Sand casting is a sand as the main molding materials, making casts of traditional casting techniques. Sand generally use gravity casting, special requirements may also be used in low pressure casting, centrifugal casting, and so on. Sand casting a wide adaptability, small, large, simple, complex, single, large quantities can be used. Sand casting mold ever made with wood, known as mold. Asahi precision casting factory to change the mold deformation, damage, and so on, apart from the single production of sand castings, and converting all high dimension accuracy and longer service life of aluminium mould, or resin mold. Although at higher prices, but still much cheaper than metal casting mold, in small quantities and large production, the price advantage is particularly prominent. In addition, high sand more refractory than metals, such as copper alloys and ferrous metals higher melting point materials such as the use of this technology. However, sand casting also has some shortcomings: as each sand mold casting only once, after getting a casting mold that is damaged, you must restyle, so sand casting production efficiency is low; and because the overall nature of the sand is soft and porous, sand casting's dimension precision is low and the surface is rougher. However, Asahi precision casting factory many years of accumulated technology has greatly improved the surface conditions of sand casting, blast effect can be comparable with the metal castings.


3. Metal casting is made of heat-resistant alloy steel casting hollow mold mold of modern technology. Type either the gravity casting of metals, but also by pressure casting. Metal-cast molds can be used repeatedly, each pouring a liquid metal to obtain a casting, life is very long, the production efficiency is high. Metal casting is not only good dimensional accuracy, surface finish, and in the case of pouring liquid metal the same, its higher strength than sand castings, but do not damage easily. Therefore, when the mass production of the medium and small casting of non-ferrous metals, as long as the melting point of the casting material is not high, generally preferred the metal casting. However, metal casting has some disadvantages: because of heat-resistant alloy steel and on top of it to make a hollow cavity processing are expensive, so metal-type mould costs a lot of money, but the overall and die costs are much cheaper than. For small batch production, is allocated to each product on the tooling costs are obviously over-paid, generally are less accepting. And because metal mold mold mold material size and cavity processing equipment, foundry equipment capacity constraints, so the casting seems to particularly large powerless. In the production of small batches and large, rarely used metal casting. In addition, metal-mould made of heat-resistant alloy steel, heat capacity is still limited, more commonly used for casting of aluminum alloy, zinc alloy, magnesium alloy, copper alloy casting has been used less, and even less for ferrous metal casting. Asahi precision casting factory of the metal mould is all on its own design, manufacture, and thus more time for the customer to provide cheap and suitable quality molds.
