The production line because the company combines western european advanced technology was developed in the 1990s.host bit SJSZ51 SJSZ65 / 131 / 105 or a conical twin screw extruder with dual units controlled stainless steel spray shaping platform, production is avoided when the tube is adjusted without affecting the other pipe of the waste, the automatic single - double traction machine and cutting machine with double front styling technique makes the operation more flexible, let you appreciate the respectively individually control both tax benefits, double pipe extrusion and the diameter of the pipe 20 from the band - band 63, to be able to make better use of the extruder, the extrusion capacity, even if the production of small diameter pipes and high yield
