The large casting’s structures are quite different, the processing content and difficulty are different. In general, the large casting are OK after the cutting, polishing and blasting, but for some special large casting need to add the processing steps.
Great Wall Casting is the China outstandinglarge casting manufacturing factory. We can undertake different kinds of large casting with different materials, to satisfy the demands of different industries. Now, Great Wall Casting will analysis the main factors for large casting cost, including the factors below:
1. Process production rate. The process production rate also be called yield, it is the percentage of exactly weight to casting weight. The lower of processing yield, the casting cost is higher. The lower of processing yield, the influence is more outstanding.
2.The shell number is range from the castings’ shape and structure.
Objectively speaking, the surface flaw of large castings is hard to avoid. Different customers or with different using ways, the requirement of casting surface are different. So it’s important to make a reasonable quality acceptance standards according to casting’s character. If the customers requirement for surface quality is high, the repair cost is also high. The repair cost is mainly influenced by large casting quality requirement and one time pass rate. The former is considered in the prices, and the latter is based on the inter quality control.
The later handling cost difference mainly come from cleaning, rectify deformation and renovating. Its cost is decided by the casting’s structures and technical requirements.
