For fulfilling the requirement of the market and acknowledgeing the persistent support of all client to us, our company has developed a high efficency , energe saving, plastic extrusion machine. It is based on the advance technology and the practicality of China. It is revolution of extrusion machine. Its fresh feature will come in front of you. SJM-Z30?0-450　SJM-Z40?8-850 SJM-Z35?0-650　SJM-Z45?0-650SJM-Z45?0-850　SJM-Z45?0-1100SJM-Z45?0-1300 SJM-Z50?8-11001.Disannul the traditional electromagnetic timing electric transmission method. The primary driver adopts frequency conversion method which reaches high performance, energy conservation and low yawp. The power expenditure can be reduced 20-50%. 2.Disannul the speed reduction unit and the mainframe screw is circumgyrateed direct by the electromotor with the belt pulley. It is very straightforward to be handled and maintained. 3.The extruding machine is widely used to machining LDPE, HDPE, LLDPE, mLLDPE, and PP etc. 4.The control box has been changed istead with operating board of which the selection of components is more reasonable and reliable and the operation is more convenience. 5.The frame of the livelong mechine is more compacted and the technics of the accessory machining and assemblage has been changed and improved greatly with which the machining precision and assemblage quality have been enchanced. 6.The circumgyrate frame head can be equiped based on the consumer's demand. 7.The mode of ballingup can be equiped with friction mode or center mode based on the consumer's demand.
