The reporter learned from South China University of Technology yesterday that South China Polytechnic International Co., Ltd. has successfully pioneered the creation of a multi-spindle convection type screw chaotic mixing type low-energy extruder at the international level. According to the appraisal organized by the Department of Science and Technology of Guangdong Province, the overall technology of “Key Equipment and Technology R&D for high-performance polymer packaging materials based on chaotic mixing†has reached the international advanced level, among which key equipment—chaotic mixing type low energy consumption extrusion The machine was the first of its kind in the world, and its energy-saving effect was remarkable. It not only broke the monopoly of long-term foreign companies' polymer extrusion line for polymer packaging materials, but also enabled more types of raw materials to be used for the production of high-barrier plastic package materials.
According to Professor Huang Hanxiong, who is responsible for the project, the market for high barrier plastic packaging materials is in great demand. However, the key equipment and technologies for this kind of material production line in China have always been relatively backward and have been monopolized by enterprises in Japan, the United States, and South Korea for a long time. In response to the above outstanding issues, South China University of Technology, on the basis of a systematic study of the polymer dispersion melting theory, and Jiangmen Huilong Plastic Machinery Co., Ltd., jointly carried out the key equipment of the production line, the extruder and the extrusion molding head. Innovative design, overcoming key technologies and developing a chaotic mixing type extruder with high plasticization, high extrusion volume, and low energy consumption. The on-the-spot inspection of Guangdong Province Technology Supervision Machinery Product Quality Supervision and Inspection Station indicated that the unit consumption of the extruder is 0.17kW/(kg/h), which is 0.15kW/(kg/h) lower than the standard value of JB/T 8061-96 standard. ); Compared with the United States, Japan and other countries on behalf of the world's extrusion extrusion machine produced by the highest level of enterprises, the extruder's extrusion output is higher, and energy consumption is lower.
Professor Huang Hanxiong said that polymer nanocomposites and blends with a viscosity greater than 1 are easy to agglomerate and process, which has been difficult to apply in plastic packaging in the past. The extruder has a unique structure that can produce a variety of effects such as shunt, convection, pressurization-decompression, extension, thinning, rolling, etc., for use in nanocomposites and blends with a viscosity greater than 1 At the same time, with the addition of a small amount of barrier materials, it is possible to produce barrier packaging products with good mechanical and heat-resistant properties, which greatly broadens the range of choices for high-barrier plastic packaging materials. Moreover, the BOPP/LDPE composite film produced by the extruder has high peel strength, and does not require some toxic organic solvents to be dissolved and coated when producing the EVA pre-coating film, thereby realizing the green composite process without the adhesion promoter.

Slotting machine is used for cutting grooves, keys and slotes of various shapes making regular and irregular surfaces both internal and external cutting internal and external gears and profiles. Slotter machine can be used on any type of work where vertical tool movement is considered essential and advantageous.
Slotter machine is defined as a machine tool uses for removing unwanted material chips from the workpiece to make splines, grooves and more. Here the Ram (Tool attached) moves reciprocating, whereas In shaper the ram moves horizontally.
