FAQ
What are we? -We are factory, with license of import and export goods by ourself.
How to get to us? The nearest airport is Wenzhou airport, and the nearest train station is Ruian station.
How do we control the quality of screw barrel? We have professional engineer and staffs to check every detail and dimensions from the raw materail, nitrding treatment and super grinding. We do the crucial nitriding treatment by ourself,


Our company :
1)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. 

2)It owns many computer-control CNC milling machines in length 8000mm 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. 

3)Due to its high quality products and outstanding customer service, Our products are sold at home and abroad, like Russia, Thailand, Malaysia, Serbia, Egypt, Morocco, Argentina, Mexico, Brazil, and other countries and regions.
