Hot Runner Mold Design: A Comprehensive Guide
Hot runner molds are an essential component in the plastic injection molding industry. They consist of two plates that are heated with a manifold system. The manifold helps maintain a consistent temperature by keeping the molten thermoplastic in the runners at the same temperature as the heating cylinder. The heated runners deliver the molten plastic to nozzles that fill the core mold to form the final part .Get more news about Hot Runner Mold Design,you can vist our website!
The hot runner system should be easy to assemble into the molds without requiring special tolerances or tools. It should be responsive to the controls and able to maintain a stable processing temperature window that is close to the resin manufacturer’s specifications without using special controls or critical settings .
DuPont has published a manual that gives guidance on basic gate design and hot runner selection for the robust molding of semi-crystalline resins 3. The manual provides insights into the design and development of hot runner systems for various applications. It describes the hot runner design requirements for semi-crystalline polymers, such as Delrin® (POM), Zytel® (PA), Minlon® (PA), Zytel® HTN (PPA), Rynite® (PET), Crastin® (PBT), Sorona® (PTT), and some Hytrel® (TPC-ET) .
