Dongguan Precision CastingIt is a metal object obtained by a casting method. Precision casting is a piece of art created by workers and masters. So, what are the characteristics of precision casting production?

The casting process design is based on the structural characteristics of the castings, combined with the actual production, to design a set of operation guidance documents and quality control documents that not only guarantee the quality, but also obtain higher economic benefits, and produce conforming documents under the premise that the implementation is guaranteed. The requested product. There are many process factors in the design of large-scale Guangdong precision casting process, and many design methods are used. Some factors that are not conspicuous in small parts have a significant impact on large parts.

Large castings are small in batches, process testing and improvement are difficult, and designers require rich knowledge and experience. The design engineering and content mainly include: process analysis of precision casting, selection of precision casting process schemes, and selection of precision casting process parameters , Precision casting forming control, casting heat treatment technology, casting process equipment design, casting post-processing technology, etc., are the core of casting process design, and the meaning of casting process design in the usual sense is this part.

Precision cast steelProcess design is compiled on the basis of summary and improvement. Precision casting is a technical management measure to obtain high-quality and high-yield castings. When selecting a precision casting process plan, the specific conditions of the foundry must be considered, such as the operating conditions of the casting equipment, production capacity, the structure and size of the steel castings, technical requirements, and production quantities. A preliminary discussion will be conducted on the main principles of the selection of the casting process plan.

Lost wax castingThe production process plan determines the future precision casting. Precision casting should also be based on the shape, size and technical requirements of the product parts drawing. Precision casting selects various casting process parameters. The casting process parameters are determined by the characteristics of the metal type and casting method. The content mainly includes casting shrinkage rate, machining allowance, draft angle, casting fillet and core size, etc., as well as process correction amount and parting negative number. When selecting the casting process parameters, it must be used flexibly according to the actual production situation.
