Advances in Powder Injection Molding Dr.liang From the table, it can been seen that the mechanical properties attainable with PIM are generally equivalent to those possible via other powder production routes. In some specific cases, the corrosion resistance of the PIM products, like the stainless steel is much more concerned. If without contamination, the PIM products are with good corrosion resistance, and often superior to the wrought products. With the developments of PIM, the PIM products got more and more wildly applications. Table 5 listed the existed applications and new possible applications .
