Injection Mould Ejector Pins For Plastic Molde Stepped Straight For Ejector Pin Sleeve Pins SKH-51 SKD-61 Material

The shape of the ejector pin is generally composed of a straight rod part (sliding part) and a non-sliding part. The sliding part is inserted into the mounting hole of the core and moves due to friction during each injection, so high-precision machining and surface roughness treatment are required. The non-sliding part is matched with the shoulder part. The root of the shoulder part suddenly changes to a step shape, which is prone to stress concentration, so annealing is usually performed to release the stress.
