The contents of the molten casting cleaning

The content of investment casting cleaning is

      (1) remove the shell from the casting;

      (2) remove the casting from the imbibition system;

      (3) remove shell refractories attached to the casting;

      (4) casting cleaning after heat treatment, such as rust removal, edge and cutting gate residues.

Investment casting process design is the task

      (1) analyze the machining performance of casting structure;

      (2) select a reasonable process plan, determine the relevant casting process parameters, and draw casting drawings on the above basis;

      (3) design the gating system to determine the module structure.

        It should be noted that, when considering the above three aspects, the main basis is still the basic principle of general casting process, especially when determining the process program and process parameters (such as casting round corner, machining allowance, process rib, etc.).Except for the specific data, the design principle is exactly the same as that of sand mold casting, because the process characteristics of investment casting are slightly different.

The task and importance of investment casting process design

       Investment casting is a casting process with little or no cutting.It is also known as lost wax casting.Compared with other casting methods, castings produced by investment casting process are cast in terms of dimensional accuracy and surface quality.The casting is very high.In addition, the investment casting method can complete the production of some complex and difficult casting, so it is very popular in enterprises.As for investment casting process, investment casting process design is one of the most important aspects in the whole investment casting process.The technical difficulty coefficient of this link is very important, which is very important for the whole investment casting process.This link is intended for professionals.Like other casting process design, the design task of investment casting process is: a.According to the specific requirements, the machining properties of casting structure are analyzed.Bay plan reasonable process planning, determine the relevant casting process parameters, and draw casting drawings on this basis.;C.The casting system is designed to determine the structure of the module. In addition to the specific data, the design principle is exactly the same as that of sand mold casting due to the slightly different casting process characteristics.Because the design process of investment casting process is very important to the whole casting process, and the designer's design quality is very high, the company should attach great importance to this link.
