Discussion on polyoxymethylene extruders
Thread Content
Most of the polyoxymethylene granulation processes in China use German CWP ZSK extruders. Are there any extruders from other brands being used as well? Companies such as Yuntianhua, United Chemicals, Tianye Chemicals, Kaifeng Longyu, Baotailing, and Zhangjiagang DuPont Asahi Kasei – have they never used domestic-made extruders? Are domestic large-scale extruders really not as good as those from German CWP or Japanese JSW KOBE in terms of performance? Those with experience, please share your thoughts…
Has anyone used the extrusion granulators produced by the Italian company Maris? The twin-screw extruders of world-class quality are said to be those made by Maris… With a reputation for excellence and reliability since 1962, Maris has played a key role in the field of compound manufacturing, specializing in the production of co-rotating twin-screw extruders. Continuous research and accumulated experience have made Maris one of the leaders in this industry on an international scale. When it comes to high-quality processing of plastic materials and rubbers, Maris extruders are the standard choice. http://www.mariscorp.com/index.php/en/extrusion-technology
There are more in Germany; they are generally imported
Our unit uses JSW’s version; it has quite a few minor issues, but no major ones. I wonder about you guys? How are the cutter blades of the pelletizer?
We’re using it. The pelletizing water pressure is always underreported, triggering a interlock.

In fact, the most crucial component of an extruder is the gearbox; the structure of gearbox in foreign extruders is almost identical, featuring an upper and lower symmetric drive design. If you have any questions regarding the structure of extruders, feel free to contact QQ185981426 for technical discussions.
Domestically produced long screws and thick screws cannot be manufactured either, as the quality of the steel is too poor
The screw material is not an issue, nor is processing a problem; we can provide imported materials and use CNC machines for processing to ensure the quality of the screws.
Manufacturers that use Polish ZAT technology, such as Yuntianhua Shuifu, Yuntianhua Chongqing, and Inner Mongolia Tianye, use Maris extruders, with the model possibly being 177； Manufacturers that employ **Fuyi technology, such as Shanghai Lanxing, Tianjin Tianjian, Kaifeng Longyu, and Shenhua Ningmei, use extruders from KEBELON (WP Company); among them, Lanxing and Shenhua use models of the ZSK-250 type ； The others are ZSK-177 ； Manufacturers that adopt Korean P&ID technology, such as Tangshan Zhonghao (a subsidiary of Kailuan Group) and Yankuang Lunan, use the Kobelco ZSK-177 and the German THEYSHON-140 models respectively ； DuPont Kyocera, which utilizes Kyocera’s technology, uses the JSW (Nippon Steel) TEX-200 model. Botai Rin (Botai Plastics Co., Ltd., Mitsubishi Gas Chemical Corp., Korea Engineering Plastics Co., Ltd., and Ticona), which employs Boron and KEP technologies, uses the JSW (Nippon Steel) TEX-251 model
As a key device for the capping process in polyoxymethylene production, Koenig & Bauer holds a high market share in this area.
