Product Description

The flexible modular principle is implemented using screw barrel sections available in a wide range of designs. These barrel sections are cooled with water through an internal bore system, where the bores are positioned close to the inner barrel wall.

We adopt horizontal CNC, and advanced processing to machine the inner hole and pin hole at one time to ensure the coaxial degree of the barrel within 0.02mm. We use the advanced 3D measuring instrument to control the tolerances of each row of the cylinder.

For bimeta barrels, generally we have three types of materials to provide:

(1) C-type liner

Bimetallic means the inside barrel hole made of alloy liner and outside base made of steel. Some typical elements for the liner can be:

(2) Oval liner

It is made from one kind of high-chromium iron alloy (Cr12MoV), which is very famous in China these years due to its high wear resistant feature and its longer service life. We take our manufacturing process to a new level by introducing the oval liner products. We follow the unique formulation and ultimate techniques in our production that gives the best results in our supply.

(3) Imported material of world leading suppliers

For even higher wear resistance and higher corrosive resistance, we use imported material from Germany SAM26 - 26% chromium, 2.7% carbon and 3.5% V.

Modular barrels are available as follows for different processing requirements.

Sales service:

Application

This screw is extensively utilized in plastic pelletizing machines, including the processing of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and other plastic materials. It is particularly well-suited for producing various plastic granules, recycled plastic granules, and engineering plastic granules.
