Yangyang Liqiang Hardware Plumbing Casting Costing

 Strictly speaking, differentHardware and plumbing casting The manufacturing cost of each process is not exactly the same, but some differences are small and can be calculated according to the average level. What we are concerned about are those factors that have a greater impact on the cost of castings. The main factors that lead to the difference in the cost of casting process are as follows:    

    Process yield rate The production yield is also called the yield, which is the actual percentage of the casting component as a percentage of the casting component. For specific castings The process yield is equal to the total weight of the casting on the same tree as a percentage of the tree weight. It is related to the casting structure and the group tree scheme, and may vary from 30% to 60%, generally between 40-50%.

    The relationship between the cost and the yield of the process is the cost of the front section of each kilogram of casting. The cost of the front part of the casting process per kilogram of casting is inversely proportional to the yield of the process. The lower the process yield, the higher the cost of the previous part of the casting. And the lower the impact of the process yield, the more significant the impact.

   /span>Hardware Plumbing CastingThe cost of the front section of each kg of molten steel is 6 yuan, when the alloy casting yield is 45% The cost of the front section of each kilogram of casting is 13.33 yuan; when the process yield is 30%, the cost of the front part of the casting is 20 yuan / kg, 6.7 yuan higher than the average level, the castings make the process The increase of 37.6%, the impact on the total cost of 304 stainless steel castings is about 17%; when the process yield is 60%, the cost of the front part of the casting is 10 yuan / kg, 3.3 yuan lower than the average, making the process cost down 18.5%, In the case of 304 stainless steel castings, the total cost is reduced by about 7%.

    The derivative of the front part of the casting can be obtained by deriving the process yield: The influence of the process yield on the cost of the front section of each kilogram of casting and the yield of the process The square of the product is inversely proportional. When the process yield is 45%, the cost of each part of the casting is 0.3 yuan for every one percentage point decrease. When the process yield is 30%, the front part of each kilogram of casting is decreased by one percentage point. The cost of adding about 0.67 yuan shows that the impact of the process yield on the cost is very significant.

    The power factor in electrical engineering, the drop in process yield is equivalent to the addition of no power consumption. Of course, the process yield is not as high as possible, and it is not as high as it is high. Excessive process yield will reduce the shrinking capacity of the gating system, resulting in insufficient shrinkage or shrinkage defects;

    Some dewaxing castingsIn particular, thin-walled castings with irregular shapes are difficult to improve due to the structure of the casting and the limitation of the grouping scheme. This important factor should be taken into consideration when approving the price of castings.
