Precision casting processing can also be divided into gravity precision casting processing and die casting according to metal precision casting processing technology. Gravity precision casting processing refers to the metal liquid in the earth, also known as precision casting processing, under the action of gravity precision casting processing technology. Generalized gravity precision casting processing includes sand casting, metal precision casting processing, investment casting precision casting processing, mud casting, etc.; narrow gravity precision casting processing refers to metal castings. Die casting refers to other external force (no gravity) metal liquid under the action of injection molding process. Ordinary die-casting, including die casting machine precision casting processing and vacuum precision casting processing, low-pressure precision casting processing, centrifugal precision casting processing, etc.; die-casting precision casting processing specifically refers to die-casting machine metal-type die-casting, referred to as die-casting. Xudong Precision Precision Casting Factory has long been engaged in sand and metal gravity casting. These types of precision casting processes are currently the most commonly used non-ferrous metal precision casting processes, and are also the lowest relative price.

Sand type precision casting processing uses sand as the main molding material to produce traditional precision casting processing technology. The sand type is generally processed by gravity precision casting, and special requirements can also be used for low-pressure precision casting processing, centrifugal precision casting processing and other processes. Sand type precision casting processing is applicable to a wide range of small pieces, large pieces, simple parts, composite parts, single pieces, and large quantities. The mold for sand casting precision machining, formerly made of wood, is commonly known as wood mold. Xudong Precision Precision Casting Factory is designed to change the wood molds to be easily deformed and easily damaged. In addition to single-production sand-type precision casting, all aluminum molds or resin molds with high dimensional accuracy and long life are available. Although the price has improved, it is much cheaper than metal precision casting molds, and the price advantage is particularly prominent in small batch production. In addition, sand is higher than metal-type refractories, so high-melting materials such as copper alloys and ferrous metals are also used in this process. However, sand type precision casting processing also has some disadvantages: since each sand type precision casting process can only be cast once, the mold after precision casting processing is damaged and must be re-modeled, so the sand type precision casting processing is inefficient; and because of the overall sand The nature is soft and porous, so the sand precision casting process has low dimensional accuracy and rough surface. However, Xudong Precision Precision Casting Factory has accumulated many years of technical accumulation, which greatly improved the sandblasting of the sand surface, and the effect is comparable to that of metal castings.

3. Metal precision casting processing is a modern technology using precision casting processing of heat-resistant alloy steel precision casting. The metal type can be processed by gravity precision casting, and can also be die-cast. The metal mold can be used repeatedly, each time the metal is melted, and the casting is obtained, which has a long service life and high production efficiency. Metal castings not only have good dimensional accuracy, but also have a smooth surface, and in the case of casting the same metal solution, the casting strength is higher than that of the sand type, and it is more likely to be damaged. Therefore, in the mass production of non-ferrous metals in small-sized castings, as long as the melting point of the precision-casting processed material is too high, metal precision casting processing is generally preferred. However, metal precision casting also has some disadvantages: metal molds are expensive because of the heat-resistant alloy steel and its hollow cavity in processing, but the overall and die-casting molds are also much cheaper. For small batch production, the cost of mold for each product is significantly too high and generally not acceptable. Since the metal mold is constrained by the mold material size and the cavity processing equipment and the ability of the precision casting processing equipment, the special casting also seems to be weak. Therefore, in small batch production, metal castings are rarely used. In addition, although the metal mold uses heat-resistant alloy steel, the heat capacity is still limited, and it is generally used for aluminum, zinc alloy, magnesium alloy castings, copper alloy castings have been used less, and even for ferrous castings. The metal molds of Xudong Precision Precision Casting Processing Factory are independently designed and manufactured independently, which can provide customers with cheap and suitable for high quality molds.
