Two platen injection molding machine – NRH series
Preferred Choice for Medium and Large Size Injection Machine



The NRH series comprises two-platen structures engineered for superior performance in molding complex, large-sized plastic parts. With clamping forces ranging from 500 to 5000 tons, these machines are ideal for large-part injection molding that reduces machine length by up to 30% and extends mold opening strokes.

Key Features of NRH Series Two-Platen Injection Molding Machine

Our two-platen injection machines are designed with innovative patented technologies that enhance precision and robustness. Key features include the patented moving platen positioning device (Patent M636571) and the suspended tie-bar bearing module (Patent M634662), both of which ensure optimal machine performance and longevity."
