Output = displacement of last thread +/- pressure flow and leakage. The displacement of the last flight is called positive flow and depends only on screw geometry, screw speed and melt density. It is regulated by the pressure stream, which actually includes the drag effect (indicated by the highest pressure) that reduces the output and […]
Throughout the series of crises caused by my country’s environment and resources, the task of waste plastic disposal has become an urgent issue. The development achieved by various countries for environmental protection is gratifying, and the recycling of waste plastic raw materials has also begun to be taken seriously. China has a large population, uses […]

In today’s automobiles, it has become an inevitable development trend that plastics are widely used in automobiles instead of expensive metal materials. High-strength engineering plastics not only reduce the cost of parts processing, assembly and maintenance, but also make vehicles lighter, energy-saving and environmentally friendly. The data shows that plastics and their composite materials are […]
Prefabricated cigarette holder processing Prefabricated cigarette holders have a lot of shapes and sizes to meet different needs. Due to the limitation of batch mold injection molding process, there are currently two main materials for cigarette holders: vulcanized rubber and acrylic polymer resin. It is a great boon for customers and maintenance personnel. Most prefabricated […]
