Turbocharger manufacturers tell you what is precision casting?
Precision casting, also known as lost wax casting, its products are precise, complex, close to the shape of the part, can not be processed or little processing on the direct use, so the investment casting is a near net shape of the advanced technology. Turbocharger turbo manufacturers since the 1940s investment casting for industrial production, half a century has been developed at a relatively rapid pace. Especially in Europe and the United States is developing rapidly. Now the investment casting for aviation, weapons sector outside, almost used in all industrial sectors, especially electronics, petroleum, chemical, energy, transportation, light industry, textiles, pharmaceuticals, medical equipment, pumps and valves and other sectors. In recent years, China has also developed rapidly. Melt casting technology development so that not only can produce small castings, and can produce larger castings, large molten die casting profile size to nearly 2m, while the small wall thickness is less than 2mm. at the same time molten die castings also tend to be more precise, in addition to linear tolerance, the parts can also achieve higher geometric tolerances. Melting die castings of the surface casting angle value is also getting smaller.
Turbocharger manufacturers produce castings to reduce the price of products is the general trend subject to the impact of a sharp drop in the price of precision casting materials, casting products across the board price reduction is an inevitable trend. Based on the high price of raw materials in 2008, the average market price of casting pig iron without tax has fallen to about 2800 yuan / t, down about 40%; scrap steel fell to about 2000 yuan / t, down about 53%; casting coke fell to about 2400 yuan / t, down about 38%. According to this calculation, the main material cost of each ton of castings was reduced by more than 2,000 yuan, and if the price reduction of ferroalloys was taken into account, the cost of castings was reduced by At the same time, the price reduction of coke has also caused a reduction in melting costs. This account is not only clear to casting production enterprises, casting users will also calculate, so the wave of price reductions in casting products is inevitable, the key is how we use the wisdom of precision casting enterprises to play with the user, in a new round of price negotiations to achieve a win-win situation.
