Special Packaging Injection Molding Machine

Design and manufacturing of plastic injection mould

Hendry built the first screw injection molding machine, revolutionizing the plastics industry. Roughly 95% of all molding machines now use screws to efficiently heat, mix, and inject plastic into molds. 1.2 Equipment Injection molding machines, also known as presses, hold the molds in which the components are shaped.
