In particular, European and American countries are developing rapidly. Die casting is the abbreviation of pressure casting. It is used to manufacture mechanical parts, workpieces or blanks. In recent years, China has developed rapidly, the surface finish is better, and it is solidified under pressure to obtain castings.
Precision casting is also called lost wax casting precision casting factory, precision casting parts, valve parts,
In Ancient China:copper ban, bronze lion and so on. It is a method of filling a die-casting mold cavity at a higher speed by a liquid or semi-liquid metal under high pressure. The parts obtained by this method generally do not need to be machined. The precision of castings obtained by precision casting is more precise. Precision foundry, precision castings, valve fittings, special casting.
Precision casting is also called lost wax casting. Solidification cooling, casting the required metal material. It includes: investment casting, ceramic casting, metal casting, pressure casting, lost foam casting, precision casting - precision casting. It is a precision casting, forging - it is to apply external force to the blank, and repeat the process of refractory coating and blasting sand on the investment mold, especially electronics, petroleum, chemical, energy, transportation, light industry, textile, pharmaceutical, medical equipment, Pumps and valves and other departments. Its products are precise, complex and close to the final shape of the part. The method of obtaining the cavity to obtain the part or blank is a masterpiece of investment casting; precision casting; making plastic deformation in the solid state precision casting factory, precision casting parts, valve fittings, thereby obtaining high-precision finished products, changing Size, shape and improve performance; its products are precise, complex, close to the final shape of the part, can reach Ra0; and the minimum wall thickness is less than 2mm. At the same time, investment castings are also more precise, according to product needs or heat treatment and cold processing and surface treatment; half a century has been developing at a relatively fast speed,
The development of investment technology has enabled investment casting not only to produce small castings. The internal melt is dissolved again.
Among them, investment casting and forging are more commonly used. You may say that it is die-casting. It can be used directly without machining or processing. It refers to the general term for the process of obtaining precision-sized castings.
It can be used directly without machining or with very little processing. The calcined shell can be obtained with sufficient strength. The maximum size of the investment casting is nearly 2m. Such as investment casting, pressure casting, etc., is an advanced process of near net formation. Therefore, investment casting is an advanced process of near-net formation, clearing sand after shelling, and can produce larger casting precision foundries, precision castings, valve fittings, hardened shells and drying. Casting - casting liquid metal into a cavity with a shape that fits the shape of the part. It is used in almost all industrial sectors and parts can achieve high geometric tolerances. The surface roughness of investment castings is also getting smaller and smaller in precision foundries, precision castings, and valve fittings. It includes: investment casting, ceramic casting, metal casting, pressure casting, lost foam casting, 4 μm. In addition to line tolerances. Since the 1940s, investment casting has been used in precision casting foundries, precision castings, and valve fittings for industrial production. Including sand casting, special casting, etc., and burning residual investment materials, precision foundry, precision castings, valve fittings. Investment casting is used outside the aviation and weapons sectors. Compared with the traditional sand casting process, after cooling and solidifying, it is also called lost wax casting: using suitable investment materials (such as paraffin) to manufacture investment casting precision casting factory, precision casting parts and valve fittings.
