Themain machine is SJSZ 55/110 or SJSZ65.152 conical twin-screw extruder, is equipped with doubletube single-control stainless steel spraying shaper to form a production line. It avoids a waste condition when one tube is adjusted and the other one is affected. The auto single-control double haul offs and cutting are combined with the front shaping technology to make operation more flexible. Let you enjoy econo-mic benefit which is brought about by separately control double-tube extruding. The diameter of the extruded pipe is from ф20-ф65. It can make fully use of the extruding capacity of the extruder. Even if it produces small diameter pipe, it can gey great output, too.
