Introduction to the Principles of Twin Screw Extruders
08 Dec,2022
The twin screw extruder has the extruder principle of a single screw extruder: solid conveying, melt boosting, and pumping, mixed stripping and devolatilization, but this is not simply the case.
Maintenance and upkeep of high-speed mixer
When using high-speed mixers, maintenance procedures should be established. In addition to following general equipment maintenance rules, the following items should also be noted:
Raw material market
The raw material of plastic pipes is plastic, and China joined the World Trade Organization on December 11, 2001 and became a member of it. By 2008, the tariff on plastic raw materials had been reduced to 6.5%.
With the continuous development of domestic plastic machinery, other countries are also entering
Due to the rapid development of plastic machinery such as high-speed mixers, foreign machinery manufacturing has accelerated its transfer to China. Some world-renowned injection molding machine companies, such as German Demark, Krupp, Badenfeld, and Sumitomo Heavy Industries, have successively entered China, and some have further established technology centers.
Classification of plastic machinery products
29 Aug,2022
According to the production process of plastic products, plastic machinery can be divided into four categories: plastic mixing machinery, plastic forming machinery, plastic secondary processing machinery, and plastic processing auxiliary machinery or devices.
The Development Prospects of Plastic Machinery
Compared to metals, stones, and wood, plastics have the advantages of low cost and strong plasticity, and are widely used in the national economy. The plastic industry holds an extremely important position in the world today, and the production of plastic products has been developing rapidly around the world for many years.
