Overview Points

Automated Feed Process

Continuous PE liner production from raw granules with automated feed system reduces handling

Precision Screw Design

70mm 38CrMoAlA nitriding steel screw (1:25 ratio) ensures consistent melt quality

Variable Speed Control

15kW motor with 0-100 RPM range enables precise output control for different thicknesses

Four-Zone Heating

Cast aluminum heating zones (0.3kW each) with cooling fans maintain stable temperatures

Vacuum Sizing System

Dual vacuum tanks with pump and gauge ensure accurate liner diameter and smooth finish

Controlled Drawing

Stainless steel cooling tank with 1.5kW motor provides controlled pulling without deformation

Low-Noise Operation

Hard-surface decelerator at 1100mm height simplifies downstream equipment alignment

Centralized Controls

Single control cabinet manages all extruder, drawing, vacuum, and heating operations

Key Features

The 70mm 38CrMoAlA screw with a 1:25 compression ratio delivers uniform plasticization of PE granules across the full 0–100 RPM speed range. Four independently controlled cast aluminum heating zones and matched cooling fans keep barrel temperatures stable, preventing material degradation and ensuring repeatable liner wall thickness from batch to batch.

A dual-tank vacuum system with dedicated pump, ball valves, and vacuum gauge calibrates liner dimensions immediately after the die head. This closed-loop sizing process produces smooth, dimensionally accurate PE liners without secondary finishing, reducing scrap rates and downstream rework.

The haul-off unit combines a stainless steel spray-cooling tank, five pulley sets, a drawing ball, and a 1.5kW variable-speed motor. Synchronized pulling speed prevents stretching or wall thinning, while the spray cooling system rapidly solidifies the liner to lock in dimensional accuracy before spooling or cutting.

A hard-surface, low-noise decelerator pairs with the 15kW main motor to deliver high torque at low vibration levels. This extends gearbox and bearing service intervals, keeping unplanned downtime to a minimum during long production runs.

A centralized control cabinet governs the extruder, drawing machine, vacuum pump, and all heating zones from one interface. Automatic granule feeding eliminates manual hopper loading, allowing a single operator to monitor the entire line from material input to finished liner output.
