Qingdao Huashida Machinery Co., LTD., as a comprehensive private high-tech enterprise integrating R&D, manufacturing, marketing, service and trade, has developed and produced the HJ-30B /HJ-30A portable plastic extrusion welding torch, which is highly favored in domestic and foreign markets due to its outstanding performance and wide application fields.
The machine uses a main unit imported from Germany and a blower imported from Switzerland as its main components. The unique screw structure design ensures more uniform and efficient material extrusion. This product is the only one in China to have passed the ministerial-level appraisal and has a utility model patent certificate (patent certificate number: ZL201020634599.1).
It has A-B-C-D-E-F-G 7 speeds, D and E are standard working speed.
PID controlling makes alarm when it overheats or needs to change the carbon brush and emergency off.
