History of B-TRUST

In 1990

Our founder Mr. Liu Duanzhang researched and developed the first spare parts of German WE240 planetary extruder, ended the China’s history of importing planetary extruder and the spare parts.


We repaired ZSE150 planetary extruder for Foshan Zhenxing Plastic Co.,Ltd. After we repaired it, it was used for 10years.


In these years, we developed HT140, HT150,HT170, HT190, HT200, HT220, HT240.

In 2000

According to customer’s request of producing magnetic card and Christmas tree leaves, we developed high wear resistant planetary screws, it benefits in it’s long life and energy consumption saving.

In 2008

We made a break though in the research and development of super wear resistant planetary screws, life is much longer than before.

In 2009-2015

We developed new modes HT260,HT280 and HT400, it benefits in it’s high capacity, and it is designed with big gear screws thus a very good plasticizing effect.


Our R&D team is keeping researching anddeveloping new product, a special planetary extrusion line is going to put into production.
