Extruder Screw Extruder Barrels Cylinder Unit Dia 50mm To 300mm Length 3500mm

Product Description:

The functionality of extruder combi barrels within twin-screw extruders is critical for maintaining smooth and efficient processes. These barrels, along with the screw elements, ensure a seamless extrusion operation. Specifically crafted for twin-screw applications, combi barrels have openings on both the side and the top. The side opening allows for efficient material feeding, while the top opening serves venting purposes, removing gases and volatiles effectively. This multifunctional design enhances performance, optimizes material handling, and supports the execution of complex tasks, highlighting the essential role of extruder combi barrels in high-performance extrusion environments.

Materials

Barrel Body

There are three kinds of material used for barrel’s main body, they are HB01, HB02,HC01. And HB01 is popular in domestic barrel application.

Barrel Liner

We choose different kinds of materials for barrel liner according to different application.

Normally, there are two main kinds of materials, one is HIP powder tool steel, and the other is domestic steel.

Types of Barrels

* Feeding barrel

* Solid barrel

* Closed barrel

* Barrels with inner liners

Quality Control

1). Materials control: All the materials are purchased from the domestic brands or Eurpean twin-screw specialty materials suppliers,which tested by elemental analysis and metallurgical inspections to ensure the quality.

2). The internal splines is checked by the spline plug to ensure interchangeability of the elements

3). All components are machined by CNC machines to ensure the shapes and tolerances of the elements

4). Adopt the European high-speed steel powder processing technology,and do the treatment according to the strict heat treatment 4.process to ensure the wear and corrosion performance same as the foreigh brands.

5). Perfessioal technical team can not only provide timely and accurate mapping sample design but also the combination of elements of technical services.

6). There are various prepared technical information and the fitxtures for the various brands extruders to ensure the timely lead time.The common components have a lot of stock, even the new one, it can be delivered within 45days.

7). The modern management system can ensure the products 100% qualified and tracked.

Product accuracy

There are some differences between Nanxiang Machinery and Nanjing's production technology. Their finishing process is carried out before heat treatment, and the deformation after heat treatment is not controlled, so their accuracy is not easy to control. But our finishing process is carried out after heat treatment, which can eliminate the deformation of parts in heat treatment, so the precision is higher, and thus can achieve zero seam connection.

Packing

According to your order quantities and products sizes to choose wooden boxes or cartons to pack:

a. Rust-proof oil processing,

b. Oiled paper packages,

c. Bubble wrap package,

d. Special foam packaging,

e. Packing,

f. Sealing.
