The drying and dehumidifying of hygroscopic materials like PA, PC, ABS, NYLON, PET, etc. are very much essential for the manufacturing of perfect and high-end physical quality products. The drying of plastic granules by ultra modern technological dryer is important when product quality, uniform properties and optical appearance are expected to fulfil high requirements. 

The 3 in 1 dehumidification dryer can fully dehumidify and heat the air in a closed circulation system. Then the low dew point dry air will remove the moisture in the plastic particles to achieve the outstanding effect of dehumidification and drying.

With outstanding drying performance, it is especially suitable for engineering plastic materials with strong hygroscopicity. For example, PPSU, HPPA, and PAEK etc. Besides, due to its optimized compact design, the machine has low heat loss, hence low energy consumption. 

We have already working with many well knowen customers expecially in engineering plastic drying. For example: Jabil, Sunwoda, salcomp, Tata etc. 

Guangdong Topstar Technology Co., Ltd is the leading One-Stop Solution provider for Injection molding.

We have 14 years' experience on auxiliary production, 9 years' expertise for industrial robots and more than 35 years' history for Injection molding machine (elite) manufacture.


TOPSTAR is one of the key robot enterprise listed on GEM in China with compound annual growth rate over 40% since 2007. In China, we have established 4 production bases cover an area of more than 350,000 square meters. The customers we are serving are more than 10,200 all around the world.  

We have been working with Well-known companies like HSI, Haier, Plasttech, Jabli, Luxshare, Sunwoda, Salcomp, Havells, Motherson…etc.  From a full range of auxiliaries and robots, to 60-5000 tons of injection molding machines, until the whole plant planning, we provide customers with the suitable and most optimal overall cost options. We are not a simple equipment manufacturer. We are an intelligent manufacturing integrated service platform, providing customer intelligent whole plant solutions.

Nowadays, manufacturers tend to claims themselves as one-stop solution provider. However, when it comes to solution design, project construction, product quality and upgrading, few companies can do well. From a tiny auxiliary, into 5500T injection molding machine, all the equipment we offered to our client are designed and assembled by our own team, in our own workshop. 

From the beginning, we have been ahead of most competitors in terms of delivery capability, response speed, and quality control.

Our equipment can share ONE development platform. Communication between machines are much more convenient. IMM, molds, robots and auxiliaries can under control in one screen. The control unit is the complete production unit. Coupled with our own rich experience, the solutions we provide are more flexible and closer to customer needs. We help our client to save cost, to keep their products competitive.
