Features and application: The production line is developed with the 1990s advanced technology of West Europe by our company. The main machine is SJSZ51/105. SJSZ55/110 or SJSZ65/132 conical twin-screw extruder, is equipped with double-tube 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 economic benefit which is brought about by separately control double-tube extruding. The diameter of the extruded pipe is fromΦ16-Φ50、Φ20-Φ75.It can fully use of the extruding capacity of the extruder. Even if it produces small diameter pipe, it can get great output, too.
