What is Precision Casting?

Precision casting is a lost wax casting process.It is also called investment casting which is widely used for producing ferrous and nonferrous Metal Casting. Precision casting has excellent surface finish and dimensional accuracy. Its product has net shape or near net shape.

Advantages of Precision Casting

1. Parts can be casted with little or no machining.
2. Time and money by combining complex parts together.
3. It is possible to produce a very wide variety of products across different industries.
4. Smooth surface without a parting line.
Application Field
Manufacturing Process
1.Injection wax or plastic pattern, wax patterns are typically made by injecting wax into a metal tool or “die”.
2.Ejecting pattern. For multiple castings, a silicon tool is usually made from the artist’s sculpture and wax is injected or poured into the resulting cavity.
3.Pattern wax assembly (tree). It is typically uneconomical to make small parts one at a time, so wax patterns are typically attached to a wax “sprue”.
4.Ceramic dipping.The assembly is then dipped into a high-grade ceramic slurry to build a ceramic shell around the wax tree.
5.Dewaxing.The wax inside the newly built shell is now removed by putting the shell in a steam-dewaxing autoclave or flash fire furnace.
6.Sintering&Pouring. Before the metal is poured into the ceramic mold or “shell”, the mold is preheated to a specific temperature to prevent the molten alloy from solidifying or “freezing off” before the entire mold is filled.

1.What are the factors that affect the dimensional accuracy of precision casting pieces?

Generally, the dimensional accuracy of precision casting parts is affected by many factors, such as casting structure, casting material, mold making, shell making, roasting and pouring, etc. Any unreasonable setting and operation of any link will change the shrinkage rate of casting, resulting in the deviation of the dimensional accuracy of casting from the requirements.
2. What are the products of precision casting?
1)Aluminum Casting: general aluminum casting | aluminum box body
2)Copper and aluminum casting: copper plate, copper sleeve | precision copper casting
3)Steel castings: large steel castings | small steel castings | precision steel castings | CDL1 | CGAS | CGKD | CGKA | CGA
4)Copper aluminum casting
5)Tungsten iron

3. In what fields can precision casting products be applied?
Precision casting products are used in all industrial sectors, especially electronics, petroleum, chemical, energy, transportation, light industry, textile, pharmaceutical, medical devices, pumps and valves.

4. What is the precision of precision casting?
Precision casting is a casting method compared with the traditional casting process. It can obtain relatively accurate shape and high casting precision. Precision casting is a finished product after casting, no other processing is required, or the amount of processing is small. It is mainly used for important and complex parts and components. Precision casting the best dimensional accuracy can be controlled within IT8 standard tolerances.

5. What are the inspection requirements for the surface quality of precision casting parts?
1)No slag, sand and other casting defects are allowed on the processing surface;
2)No flying burrs;
3)No scratches or bumps on the processing surface;
4)Sharp angles shall be ensured at the intersection of the grinding surface and the processing surface.

6.What are the technical requirements of precision casting parts?
1) Material requirements.The main hardness, tensile strength, elongation, impact toughness.
2) Dimensional accuracy and position accuracy.Different castings have different requirements, adopt different size and geometric tolerance standard and different tolerance class.
3) Stipulate acceptance requirements for other defects of castings according to use requirements.Such as porosity, sand hole, shrinkage, shrinkage, slag, sand, crack.
4) Requirements for defect repair.Mark the quantity, material, processing precision, casting implementation standard, appearance treatment of non-processed surface, weight, casting round corners, casting shall not have pores, sand holes, cracks and other defects.
