▣ Injection / Extrusion Cylinder



CYLINDER Overview

As a heating device, thermal stability (cylinder thickness) is required to maintain a constant melting temperature. In addition, precise straightness (+0.02) should be maintained to prevent unnecessary frictional heat during screw rotation.


Cylinder wear

Abrasion is mainly caused by abrasion and corrosion generated at the leading end (4D) where the screw head flows, and abrasion caused by friction generated at the resin inlet (first 5D) during weighing.


Allowable wear

Low Viscosity Resin -0.1mm, High Viscosity Resin -0.2mm


Cylinder selection

Recently, in order to improve the physical properties of resins, various resins such as reinforced plastic resins and super-enpra resins, in which glass fiber or Fila is added to resins, have been developed. The cylinder of the material should be selected and used.
