该生产线系本公司结合西欧九十年代末先进技术开发而成。主机为SJ/SZ51/105或SJSZ65/132维形双螺杆挤出机，配以双管单控不锈钢喷淋定径箱，生产时避免了一管调整而影响另一管的浪费现象，自动单控双牵引机和切割同前面 双定型技术融为一体，使操作更加灵活，让您领略分别单独控制双管齐下带来的效益，双管挤出管径从①20-063， 能充分利用挤塑机的挤出能力，即使生产小口径的管材也可以达到极高的产量。

The production line is developed with the 1990s advanced technology of West Europe by our company.The main machine is SJSZ 21105,0rSJS265/132 conical twn-screw extruder,equipped with double tube single-contol stainless Steel spraying shaper tank to haul-off and cutter are combined with the front shaping technolooy to make operalion mor P0Alg1ACJCCOILMO COUOE whichis brought about by separately control double-tube extrucding.The diameter of the extruded pipe is from ①20-063.It can make fuly use of the extruding capactiy of the extruder.Even if it produces smalldiameter pipe,it can get great output,too.
