5.Company:
Zhejiang pinbo plastic machinery co.,ltd is located in ruian wenzhou city with brand of PYM(Former Ruian yumin machine screw co.ltd since 1988). The company is specialized in making screw barrel, gearbox zlyj series, t die, filter and extruder machine. It has become one of the largest supplier of main parts in Ruian city which is the basement of plastic machines.Â
It owns many computer-control CNC milling machines in length 8000mmÂ
In Fanuk series, 18000mm length deep hole drilling machine and
 other advanced equipment. Long time nitriding treatment for 7days and nights greatly ensure the hardness and lifetime of its products. Meanwhile, the company and its products have passed assessment by SGS company, Bureau of Veritas, Tuv and Ce certificate.
