Precision casting technical requirements

(Summary description)For example,sand mold precision casting,mass production of the factory should create conditions to adopt advanced technology modeling,core making method.The production line of the old shock type or shock type molding machine is not high enough,the labor intensity of workers is big,the noise is big,do not adapt to the requirements of mass production,should be gradually transformed.

Information
For example,sand mold precision casting,mass production of the factory should create conditions to adopt advanced technology modeling,core making method.The production line of the old shock type or shock type molding machine is not high enough,the labor intensity of workers is big,the noise is big,do not adapt to the requirements of mass production,should be gradually transformed.For small castings,we can use horizontal or vertical parting production line without box high pressure molding machine,solid molding production efficiency is high,the floor space is also small;For the medium parts can choose a variety of box high pressure molding machine production line,air punching molding line,to meet the requirements of fast,high precision modeling production line,core manufacturing methods can be chosen:cold core box,hot core box,shell core and other efficient core manufacturing methods.
Resin self-hardening sand molding and core-building may be considered for medium-batch large castings.
For heavy castings produced in small batches,manual molding is still an important method.Manual molding can adapt to various complex requirements,which is more flexible and does not require a lot of process equipment.It can apply sodium silicate sand,VRH method sodium silicate sand,organic ester sodium silicate sand,clay dry sand,resin self-hardening sand and cement sand,etc.For heavy castings produced by single piece,the pit molding method is of low cost and fast operation.
Batch production or long-term production of fixed products using multi-box modeling,split box modeling method is more appropriate,although the mold,sand box and other high investment,but from the saving of modeling hours,improve product quality can be compensated.Low pressure casting,die casting,centrifugal casting and other casting methods,due to the high cost of equipment and molds,so only suitable for mass production.The condition method should be suitable for,for example,the production of large machine tools,bed and other castings,generally using the core molding method,no shape and sand box,in the pit core;And other factories are using sand box modeling method,the production of shape.
Different enterprises have different production conditions(including equipment,site,staff quality,etc.),production habits,and accumulated experience.According to these conditions,they should consider what products are suitable for and what products are not(or cannot)suitable for.Precision requirements and cost Different casting methods obtain different casting precision,initial investment and productivity are not consistent,and the final economic benefits are also different.Therefore,to achieve more,faster,better,save,should give consideration to all aspects.A preliminary cost estimate should be made for the casting method to determine the casting method with high economic benefit and guarantee the casting requirements.
