With regard to production specifications, LESUN not only offers standard twin screw extruder parts made by general extruder screw manufacturer, but also provides special-purpose extruder parts design and manufacturing service according to your requirements.

Screw Barrel Manufacturer

Extruder Screw Barrel Diameter:

φ20 mm ~φ300 mm

Extruder Screw Barrel Properties:

Wear-resisting, Corrode-resisting, Durable

As a professional screw and barrel manufacturer and twin screw barrel manufacturer, Nanjing Lesun Screw Co.,Ltd specialize in the manufacture of parallel co-rotating modular Barrel, involving various types ranging from Ø20mm to Ø300mm. After more than 10 years of luxuriant development, our company now owns several sets of advanced CNC machines and special processing equipment for manufacturing screw.

Barrel plays an important role inside extruder. Barrel contain screw element. Screw element works inside Barrel. Barrel and screw barrel design are corporated each other to support extruder process smoothly.

To extend lifetime of components, anti-brasion and anti-corrosion performance are crucial. Lesun twin screw barrel is mainly with material of Bi-metal liner + 45# steel cylinder; N00 nitriding steel; H6 or D11. Furthermore, High wear-resisting and high corrode-resisting HSS-PM and other special steel material are also available.

As a professional twin extrusion machine screw barrel manufacturer, Lesun can supply standard screw barrel such as standard extruder screw barrel and side feed barrels, closed screw barrels, open screw barrels, combi screw barrels for many overseas extruder brands like Coperion, Leistritz, Berstorff, Toshiba, JSW, Kobe, APV, Maris etc.

Is barrel cleaning a challenge? Cleaning your equipment doesn't have to be a dirty or dangerous job if you use the right extruder barrel cleaning tools to clean screw and barrel between jobs.

Processing Characteristics of Screw Barrel:

1. Suitable suggestion on material to ensure components performance and extend lifetime of products.

2. Professional technical team can provide surveying and mapping support.

3. All components are finished by CNC machine.

4. The screw and barrel manufacturer's sophisticated quality managment system ensure superior quality.

Screw and Barrel Wear Tolerances

The screw and barrel manufacturer controls screw and barrel wear tolerance in a critical scope for all plasticating applications. The screw and barrel tolerances for the diameters on the drive shank will be typically +/-. 001" and the lengths will be +/- 1/32" (. 030").
