Foundry casting refers to the use of clay bonded sand for casting, molding materials production is the process method has a long history, is widely used in various industries, of course, jewelry industry is no exception. Small make up today to tell you something about foundry manufacturing jewelry casting technology is introduced. Foundry casting will act the role ofing is tasted the second half of the first type on the tablet, put sand filling sand compaction, leveling the type made out, will make good jewelry sand mold turn 180 degrees, put half type, parting agent, put sand, sand filling and tight, leveling, will be on the sand box turn 180 degrees, pulled out, the second half of the type, then turn 180 degrees and the combined well, ornaments made out of sand mould, wait for pouring. In manufacturing accessories foundry casting, to consider how sand box up and down to remove the wooden separately, but also the molten iron from where flow, how to fill the cavity in order to get high quality castings. After sand mold is made, can casting, molten iron with sand mold cavity. When pouring, hot metal temperature in 1250 & ndash; 1350 degrees, melting temperature is higher. Then pass desanding, repair, and grinding process, such as to become a qualified castings. Casting foundry in the production process of the characteristics of the resin sand is more, such as its core sand, high precision castings, high strength high melting away, high curing efficiency, and mass production of a variety of its complex medium and small casting core provides a kind of ideal method, thus quickly in automobile, tractor and internal combustion engines and other industries widely used. Foundry casting again because of its high precision, high melting away and the model of high strength such as low core labor intensity, when making use of to meet many varieties and small batch production of various kinds of structures has become increasingly complex, large casting mold core, also play a very important role. At present, the resin sand process is various, according to the different way of hardening, divided into three categories: heating hardening process, blowing air hardening method and the process and the method. Foundry casting the core of the experience of effective after its external heat source for the heat, it will make its core sand under certain temperature and time of curing a craft, foundry casting due to the coated sand fluidity, filling and storage are all good, good strength, melting away, by the auto industry are widely used in large quantities in the production of various complex structure, high quality requirements of the core. Above is about foundry manufacturing jewelry casting technology is introduced, the hope can help to you. Today small make up to you at this point, let's see you next time.
At a time when technology is essential for cast iron suppliers, ensuring that it works in a symbiotic way with your human employees is key.
