    Precision casting processing skills required

Large production of the factory should create conditions for the selection of advanced modeling skills, core-making methods.The old shock type or shock compression type molding machine production line production rate is not high enough, the worker labor intensity is big, the noise is big, does not have the habit of mass production requirements, should be gradually transformed.For small castings, the production line of no-box high-pressure moulding machine with horizontal or straight parting can be selected, and the production efficiency of solid moulding is also high and the area is small.As for the middle part, we can choose various production lines of high pressure molding machine and air impact molding line. In order to meet the requirements of quick and high precision molding production line, we can choose core making methods: cold core box, hot core box, shell core and other efficient core making methods.

For large castings of medium batch, self-hardening sand molding and coring can be considered.

Single small batch production of heavy castings, craft modeling is still an important method, craft modeling can be used to a variety of complex requirements more sensitive, do not require many process equipment.Can use sodium silicate sand mold, VRH method sodium silicate sand mold, organic ester sodium silicate self-hardening sand mold, clay dry mold, resin self-hardening sand mold and cement sand mold;As for the heavy castings produced by single piece, the pit molding method is adopted with low cost and fast production.

Bulk production or long time production of finalize the design of the product selection of multi-box modeling, split box modeling method is more appropriate, although the beginning of the mold, sand box investment is high, but can be saved from modeling time, product quality improvement to get compensation.Low pressure casting, die casting, centrifugal casting and other casting methods, due to the high cost of equipment and mold, so only suitable for mass production.The condition method should be suitable for example, is also the production of large machine tool bed and other castings, generally choose core modeling method, do not produce appearance and sand box, core in the pit;And other factories choose the sand box modeling method, manufacturing appearance.

Different production conditions (including equipment, site, staff quality, etc.), production habits, accumulated experience are different, should be based on these conditions to consider what is suitable to do the product and what is not suitable (or not) to do the product.The casting precision required and cost obtained by various casting methods are different, the initial investment and production rate are also inconsistent, and the ultimate economic benefits are also different.Therefore, in order to achieve more, faster, better and less, we should take into account all aspects.Initial cost estimates shall be made for the casting method selected to determine the casting method with high economic benefits and to ensure casting requirements.
