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:
| material type | chromium | carbon | other |
| α 101 | 20% | 2.5% | 8% V |
| α 301 | 18% | 2.5% | 6% Tungsten |
(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:
Commissioning service includes supervision of installation and
start-up, on-site training. Service charges are free.
· Free technical service and technical consultation should be
adhered to before, during and after sales.
· Provide a complete set of technical information (including
electrical schematic diagram, wiring diagram, outsourced parts
instructions, product use instructions, etc.).
· Provide unit production process layout drawing, main screw
assembly drawing, transmission box overhaul drawing;
· With the change of processing materials and processes and the
development of new products, the corresponding screw assembly
drawing and various technical consultation are provided free of
charge.
· The equipment is guaranteed free of charge for one year. After
the expiration of the warranty period, we still insist on
after-sales service, spare parts only charge the cost price.
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.
