WebbToday, screw injection machines represent the vast majority of injection machines. Other widely used molding methods include blow molding, compression molding, or vacuum molding (thermoforming). Now, the injection molding market has reached $300 billion. This process produces more than 5 million tons of plastic parts yearly worldwide. WebbInjection screw designs normally have additional turns of feed section to compensate for this starvation. Barrel and screw lengths in extrusion have constantly increased from 20:1 (introduced in 1950) to 30:1 plus (introduced in 1960). The reason for this increased length is described in the formulas for rate and pressure flow.
