Manufacturing and processing costs of Dongguan precision foundry

Dongguan precision casting plant processing can also be divided into gravity precision casting processing and die casting according to the metal precision casting processing technology. Gravity precision casting processing refers to the metal liquid in the earth under the action of gravity precision casting processing technology, also known as precision casting processing. Generalized gravity precision casting processing includes sand casting, metal precision casting processing, investment precision casting processing, mud pouring, etc.; narrow gravity precision casting processing refers to metal castings. Die casting refers to the metal liquid with other external forces (without gravity) under the action of the 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 refers to metal die casting of die-casting machine, referred to as die-casting.
Sand precision casting processing is based on sand as the main modeling material. Dongguan Precision Casting Factory produces traditional precision casting processing technology. Sand molds are generally processed by gravity precision casting, and can also be processed by low-pressure precision casting and centrifugal precision casting when there are special requirements. Sand mold precision casting has a wide range of applications, small pieces, large pieces, simple pieces, composite pieces, single pieces, and large quantities can be used. Sand mold precision casting processing tools, formerly made of wood, commonly known as wooden molds. Hongzhe precision precision casting factory is to change the defects of wood molds that are easy to deform and damage. In addition to single production sand precision casting processing, all aluminum molds or resin molds with high dimensional accuracy and long service life are available. Although the price has improved, it is much cheaper than metal precision casting molds. In small batch production, the price advantage is particularly prominent. In addition, sand is higher than metallic refractories, so high melting point materials such as copper alloys and ferrous metals are also used in this process. However, sand precision casting processing also has some disadvantages: because each sand precision casting can only be cast once, the mold after precision casting is damaged and must be remodeled, so the production efficiency of sand precision casting is low; and because of the overall sand The nature is soft and porous, so the precision casting of sand mold has low dimensional accuracy and rough surface. However, Hongzhe's precision casting processing plant has accumulated many years of technology, which has greatly improved the blasting situation of the sand surface, and the subsequent effect can be comparable to that of metal castings.
3. Metal precision casting processing is a modern technology that uses heat-resistant alloy steel precision casting processing precision casting processing. The metal mold can be processed by gravity precision casting or die casting. The metal mold can be used repeatedly, each time the metal is melted, the casting is obtained, and the service life is long and the production efficiency is high. Metal mold castings not only have good dimensional accuracy and smooth surface, but also have higher strength than sand molds and are more likely to be damaged when the same metal solution is poured. Therefore, in the mass production of non-ferrous metals in small castings, as long as the melting point of the precision casting material is too high, metal precision casting is generally preferred. However, metal precision casting processing also has some disadvantages: because heat-resistant alloy steel and its hollow cavity in processing are more expensive, the cost of metal molds is expensive, but the overall and die-casting mold costs are also much cheaper. For small batch production, the mold cost of each product is obviously too high, which is generally not easy to accept. Since the metal mold is restricted by the mold material size, cavity processing equipment, and the ability of precision casting processing equipment, special castings seem to be weak. Therefore, metal castings are rarely used in small batch production. In addition, although the metal mold is made of heat-resistant alloy steel, the heat capacity is still limited. It is generally used for aluminum, zinc alloy, magnesium alloy castings, copper alloy castings have been seldom used, and even reduced for ferrous metal castings. The metal molds processed by Dongguan Precision Casting Factory are all independently designed and manufactured independently, which can provide customers with cheap and suitable high-quality molds in time.
