It can meet the stable transmission of melt, accurate injection control,effective guarantee of plasticization quality and equipment operation coordination. It does not need to use the drying  function of the auxiliary machine to put the melt in the process.

Moisture,volatile additives and low molecular gas raw materials are directly discharged,with the  characteristics of high performance, high efficiency, good stability and long effective service life. For special engineering plastics that are prone to the production of small molecular volatiles and  very low moisture content in the processing process, the internal circulation dehumidification  series injection molding machine can effectively remove the gases generated during the processing  process, easily solve the problem of unqualified product performance indicators

caused by poor dehumidification, and avoid high energy consumption problems caused by drying for  a long time. In addition to showing good adaptability to the processing of biodegradable plastics and  high proportion of recycled plastics, it can also meet the strict requirements of the drying effect of  transparent plastic parts.

Internal circulation dehumidification injection molding can streamline processing molding equipment, save equipment space, save labor and material costs, and have obvious value advantages. At  the same time, it can effectively avoid the problem of poor product molding quality caused by mixed  with a large number of gases in the melt.

Internal circulation dehumidification series injection molding machine as an important branch of  the injection molding machine market, will lead Innovative design of injection molding machine,help  to promote the green and low-carbon sustainable development of the plastics industry.

Application field

In line with the injection molding industry where all raw materials need to be dried to remove moisture in order to be processed and produced, the focus is on the processing field of ABS, PET, PC, PA, POM, PMMA, engineering plastics and biodegradable plastics that are easy to absorb moisture.

-Biodegradable plastic products：Raw materials usually use underwater granulation, raw materials contain a variety of small molecules, water, drying is a necessary process. The use of Macro inner cycle dehumidification series injection molding machine can be directly produced without drying, and the products are easy to debug and have good quality.

-Transparent plastic product：Transparent plastic injection molding, the need for dehumidification and drying must meet the standard, otherwise it is easy to appear the appearance quality defects that can be identified by the naked eye, especially the thick wall products are more difficult to process, and the macro cycle dehumidification series injection molding machine can easily solve such problems.

-Engineering plastics and high temperature dehumidification drying plastics：Engineering plastics and modified plastics have special functions, injection molding applications are very wide, but the need for high temperature dehumidification drying, removal of small molecular volatiles and reduce water content, in order to produce qualified injection molding products, macro inner cycle dehumidification series injection molding machine can easily solve the problem of dehumidification drying unqualified and high energy consumption.

-Recycled material：The recycling process of recycled plastics, after several decomposition, small molecule content or moisture content is high, in the injection process, the quality of the product, whether gloss or internal performance, has a great impact, conventional drying, dehumidification means, it is difficult to solve these difficulties, and macro inner cycle dehumidification series injection molding machine is developed to solve this problem, can be perfectly solved. The application prospect is broad and the potential is huge.
