Injection Molding Screws Are Critical To Part Quality

Another aspect of screw design is the length to diameter ratio (L/D) meaning how long it is compared to its diameter. As an example, the L/D ratio for PP and PE is in the range 20-30:1. When it comes to general purpose screws, longer screws are usually preferred because they will produce a better quality melt and therefore produce better injection machine screw design
