Precision casting is the new up in recent years, high quality, high precision casting. It has transformed the original castings simple and coarse brand image, is the brand image of casting goods have fine management improvement. Precision casting goods can be completed with less drilling or zero cutting production processing, but also can cast the appearance of more complex and detailed parts, this characteristic is all the past casting can not reach.

Although the precision casting can do very high precision regulations, but in the production process will also encounter some small problems, if the surface of some castings will occur black spot condition. To deal with this problem, we need to choose up to standard raw materials when selecting casting materials, and the strict implementation of technical standards and the use of the need to carry out, not just the actual operation of machinery and equipment, in order to prevent the quality of the castings. In addition some auxiliaries or preservatives are selected to ensure that there is an excellent application of the actual effect, and at the same time to prevent the emergence of a variety of side effects. Therefore, the dosage of additives and auxiliaries and the method of operation should be strictly in accordance with the requirements of the actual operation, not to have the slightest error.

If a barrel leak or steel leak occurs in a precision casting, the actual cause will also be in the casting itself, possibly because of insufficient compressive strength of the mould shell or incorrect operation of the adhesive. The main provision for precision cast parts is to carry out cleaning of the casting surface so that it is free from shortcomings and problems such as slag, oxidation, burrs, etc.

Precision casting has brought faster spare parts for various fields, and at the same time mentions the technical strength of the casting production and processing.
