The stainless steel molding j channel trim strips by injection of powders, PIM (Powder Injection Molding) and its variant applied to metals, constitutes a technology of forming of materials developed in the twenties and that has experienced a breakthrough, fundamentally , in the last fifteen years. The refinement of the precision molding equipment quickly developed the commercial viability of the MIM and it has been estimated that the annual growth of this technology is over 50%.
Stainless steel molding j channel trim strips is a new forming process that combines the flexibility and high productivity of the injection of thermoplastics with the mechanical performance of metal parts. Thanks to this combination of manufacturing engineering, products with high mechanical and morphologically complex performance can be competitively obtained.
Stainless steel molding j channel trim strips must be used because it is a technology without competition for the production of large series of small pieces with high geometric complexity and high mechanical performance compared with other techniques that make this type of pieces. However, as far as metallic materials are concerned, stainless steels, low alloy steels and some non-ferrous alloys are used to a large extent. Formed by injection in a mold, where a piece called “piece in green” is obtained, which can be easily manipulated and which has dimensions superior to those of the finished piece.
