A variety of processes are used by metal casting machinery to remove excess material from investment castings. One method involves using mechanical means like grinding, cutting, or machining. Specialized equipment, such as grinders or lathes, carefully removes any unwanted metal from the casting to ensure the final product meets the desired specifications.
Another technique used for excess material removal is sandblasting or shot blasting. This process involves propelling fine abrasive particles at high speed onto the investment casting, effectively eliminating any excess metal or surface imperfections. Sandblasting or shot blasting is particularly useful for larger castings or intricate shapes where mechanical means may not be as effective.
Chemical processes are also occasionally employed to remove excess material from investment castings. Chemical etching or pickling involves applying a solution to the casting to dissolve or erode away the unwanted metal. This method is highly effective for eliminating surface oxides or scale from the casting.
Furthermore, heat treatment can be used to remove excess material from investment castings. Controlled heating and cooling cycles subject the casting to processes like annealing or stress relieving, selectively removing specific areas of excess material. Heat treatment not only aids in eliminating excess material but also enhances the mechanical properties of the casting.
In summary, metal casting machinery combines mechanical, chemical, and thermal processes to handle the removal of excess material from investment castings. These methods guarantee that the final castings meet the desired specifications and are devoid of any imperfections or excess material.
