Durable Construction for Industrial Reliability

✔ High-Grade Mild Steel Body
Offers superior rigidity and heat distribution, ensuring stable extrusion even during long
production cycles.

✔ Nitrided / Hardened Surface Layer
At 68 HRC, the barrel and screw surface resist:
● Corrosion
● Wear
● Friction
● Thermal stress

This extends the life of both screw and barrel significantly.

Customizable for Any Extrusion Line

We manufacture screw barrels in sizes from 20 mm to 150 mm, ideal for:
● Plastic extrusion machines
● Recycling extruders
● HDPE/LDPE/LLDPE pipe plants
● Blown film extruders
● Sheet & profile extruders
● Granule pelletizing machines
● Cable & wire coating lines

Customization Options Include:
● Screw diameter
● Barrel length (L/D ratio)

● Screw compression ratio
● Venting / non-venting designs
● Mixing sections
● Grooved / smooth feed zones
● Special coatings (optional)

Each screw barrel is built to match your exact machine requirement.

Engineered for High-Performance Extrusion

✔ Precision Melt Flow
