  Updatetime:2018-08-07 Hits:

  To extend volume growth and enhance competitiveness, our company organized and developed the supply market of small-sized refined products recently.

  Xingtai Xinxiang Metallic Materials Technology Co., Ltd has had the ability to produce the refined wire fromΦ4.0mm to Φ41.0mm since 2005, but the refined products under Φ4.0mm is still a blank. To fill the output gap of the small-sized refined wire, Xinxiang actively researched the market of small-sized refined wire and user's demands, developed production process of small-sized products and rebuilt and optimized production equipment conditions on the scene. Now, Xinxiang has had the ability to produce small-sized refined wire. Up to now, the Φ2.85mm and Φ3.80mm refined wire have been developed and they are going to be put into market, which will instill new vitality into the growth of our company.
