Precision casting production of precision castings, surface finish, the density of material and microstructure and mechanical properties are often poor, so when casting these performance requirements higher, other casting method should be used, such as casting, lost wax casting, die casting, low pressure casting, and so on, edited by the company to introduce the below:

A. The characteristics of precision casting and advantages:

Precision casting and investment casting, compared with other casting method and parts forming investment casting has the following features:

1. Casting dimension precision, surface roughness, the dimension precision of casting can reach level 4, 6, the surface roughness of 0.4-3.2 mu m, can greatly reduce the casting machining allowance, and can realize WuYuLiang manufacture, reduce the production cost.

2. The casting shape is complex, and difficult to use other method processing of castings. The casting dimensions to a few millimeters to thousands of small mm, thickness 0.5 mm, the thinnest below the holes by 1.0 mm.

Unlimited: 3. Alloy material such as carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy and high temperature alloy, titanium alloy precision casting production and precious metals and other materials are available. For forging, welding and cutting hard alloy materials, particularly applicable methods of the precision casting production.

4. High production flexibility and strong adaptability. Both can be used in mass production, also applicable for small batch and single production.

To sum up, precision casting with a small investment scale, large production capacity, low production cost, the advantages of complex product process simplification, investment, fast effect. Thus in competition with the rest of the process and the means of production in a favorable position, a bright future.

* in embryo stainless steel shell, for example:

Traditional mechanical bei pressure processing methods, the most simple shell embryo bei 2 times, the machining cost (mould, bei pressure, tempering, materials) about 3-5 yuan /, with precision casting technology, the manufacturing cost at about 1.2 yuan/a, a set of precision casting equipment on the production shell embryos at about 10-150000.

2. Precision casting scope of application:

Applied to almost all industrial sectors, especially in aerospace, aviation, shipbuilding, steam turbine and gas turbine, weapons, electronics, petroleum, chemical industry, nuclear energy, transportation, light industry, textile, pharmaceutical, medical equipment, instruments, machinery, pump and valve, sports equipment, household appliances, in recent years a large number of used in tableware, tools, watch, jewelry, and hardware and so on.

3. Precision casting production equipment and auxiliary equipment:

1. Precision casting a set of production equipment: note wax link of all kinds of equipment, shell making links all kinds of equipment and post-processing equipment, the dewaxing link link of all kinds of equipment, etc

2. The precision main auxiliary equipment:

A: diesel tank b: c: air compressor air conditioner d: smoke wet machine

E: temperature measuring instrument f: water issue: cooling water, chilled water, emergency water

4. Precision casting main raw materials:

A. metal materials: stainless steel, copper alloy, titanium alloy, etc. Various kinds of metal sheet, rod, leftover material, back to the furnace charge, etc.

B. auxiliary materials: medium temperature wax material, silica sol, zircon powder sand, Malay powder sand and so on all kinds of refractory materials.
