U-Pack Series – New Injection Molding Machines

Application and expectation of extensional rheology plasticizing system in PET preform injection molding system.

U-PET130E special-purpose preform injection molding machine is a brand-new preform injection molding system, with electric design adapted for the clamping unit. It relizes high-speed mold opening and closing, excellent precision and energy-saving effect.

Extensional rheology plasticizing, processing and molding method is adopted in the pre-plasticizing unit, with advantages of high material adaptability, short thermal mechanical process, excellent dispersive mixing effect, outstanding product performance and other characteristics. Dynamic injection technique is adopted in the injection unit. Dynamic injection effectively reduces injection pressure, shortens the pressure maintaining period, decreases inner stress of the product and the like. Dynamic injection technique reduces energy consumption during the molding process, improves product quality and creates the maximum value for customers.
