Determination of the Depth of the Screw Grooves in the Exhaust Screw and the Pump Ratio
The groove depth of the venting screw and the pump ratio are critical parameters in screw design, directly influencing venting efficiency, plasticization quality, and extrusion stability.
Surface Treatment and Service Life of Injection Molding Machine Screws
Injection molding machine screws operate under conditions of high temperature, high pressure, high mechanical torque, and significant friction; therefore, surface treatment technologies are critical for enhancing wear resistance and extending service life.
