Many tools either have 3-plate gating or are a “hot-to-cold” drop hybrid. For this, Progressive offers Puller Pins™ available off-the-shelf at nominal lengths to match standard plate thicknesses. Unlike how pins are typically finished in-house, Puller Pins are ion nitrided after the undercut geometry is finished and polished, resulting in a wear-resistant, ‘sealed’ surface. Then, rather than having pins riding against non-hardened mold plates, hardened Stainless Steel Puller Pin Bushings prevent wear and the resulting particulate.
