EXTRUDER SCREW AND BARREL MANUFACTURER

Company introduction:

Meizlon Machinery has engaged in plastic extruder machinery since 1994 with comprehensive experience on both spare parts and extrusion line machinery, with the capacity more than 300 sets extrusion line per year and more than 500 sections barrel per month, owns good reputation in clients based on stable quality, timely service and competitive price.

Extruder screw introduction:

Screw Kneading block built on modular principle allows various L/D ratio of screw easily be changed to suit different material. Screw component made of high speed & wear-resisting steel.

Screw material:

1. High speed tool steel W6Mo5Cr4V2

2. Nitrided steel 38CrMoAlA

3. Cr12MoV

Process technology:

Boring--heat treatment-- face cutting -- rough turning of external diameter-- surface grinding -- Grinding inside holes -- angle of chamfer -- inside groove --finish turning of external diameter--finish turning of bottom diameter--polishing--vacuum quenching--finishing grinding of external diameter

Screw elements introduction:

Inner hole shape: involute , six spline , single spline, inner hexagon, cruciate spline

Kneading block angle: 30/45/60/90

Extruder barrel introduction:

By means of the replaceable screw barrel sections, the processing sections is devided into individual zones. The barrels are heated electrically. In addition, the barrels are provided with longitudinal bores for cooling with water. Uniform temperature distribution, namely on the circumference of the eight-shaped barrel bore, is achieved by a reverse force-flow temperature control circuit. Connections of pipes for temperature control are in groove-tongue design to balance alternating thermal stress and avoid leakage.

The screw barrels are made of nitrided steel. In order to increase the service life of the screw barrels, these are provided with wear resistant inserts.
