Deep Hole Drilling for Injection Molding Machine Parts
Injection molding machines are workhorses of the plastics industry. Every machine has tie bars, plasticizing barrels, and platens that require deep hole drilling. These components operate under high pressure and cyclic loading, so the bore quality directly affects machine reliability. I have drilled injection molding machine components for several OEMs over the years. The parts range from 2-meter tie bars to 4-meter plasticizing barrels with complex internal geometries. Tie bars in particular share similarities with general long shaft deep hole drilling but with specific requirements for hydraulic oil passage bores. ...
