introduction

The screw section has the screw groove fixed depth, its main functions are mixing, melting glue output and delivery, measurement, and it must provide enough pressure to keep melting glue uniform temperature, stable flow of molten plastic and measuring section length to ensure mixing effect better. If the measuring section is too long, the melt will stay too long and produce thermal decomposition. Too short will make the temperature uneven.

Specifications:

L/D = screw working length (MM)÷ screw diameter (MM)

Screw compression ratio = feeding tooth depth (MM)÷ measuring tooth depth (MM)
