企业简介：

   苏州太尼费尔精密五金有限公司是应众多欧美、日本等着名企业中国工厂精密部品由国外采购转为“中国制造”“中国配套外包”，专业供应商紧缺的形势下由从事多年精密五金加工的王宏先生，在中央直属企业----中国机械科学研究院武汉材料保护研究所专家教授大力支持下于2008年投资创建。专业从事精密五金加工制造及QPQ加工的企业。

  QPQ盐浴复合处理技术是世界金属盐浴表面强化改性技术，它是在两种不同性质的盐浴中在金属表面渗入多种元素，使其耐磨性和抗蚀性比常规热处理和表面防护技术成十倍的提高。同时该技术还具有几乎不变形、无公害、节能等优点。我国专家经过多年的试验研究，终于独立开发出成份独特的盐浴配方，不仅打破了德国迪高沙公司对这项技术的国际垄断，而且在环保无公害方面比德国更先进，达到国际水平。该成果以其技术先进、性能优越、质量稳定而倍受广大用户欢迎，已经大面积推广，成为重点新产品，九五期间国家重点推广项目。并获得联合国发明创新奖、国家科技进步奖、国家环保成果奖、湖北省科技奖、湖北省科技进步奖……等等。

Enterprise brief

   introduction:

   Suzhou Tenifer Precise Hardware Ltd. purchases Suzhou very much from abroad being a precise headquarter of enterprise Chinese factory product respond to a lot of Europe and America , Japan etc. turn into "Chinese supporting outside parcel " "made in China " , the investment special field is taught to strongly support down under short-supplied circumstances of supplier from being engaged in Mr. Wang Hong  that precise hardware processes for many years , protecting the research institute expert in enterprises administered by the central authorities- - - - Chinese machinery science research institute Wuhan material on 2008 establishes. Special field be engaged in precise hardware processing the enterprise that fabrication and QPQ process.

The QPQ salt bath compound treatment technology is that the world changes the nature technology intensify new metal salt bath outside most, it seeps into the various element in metal outside , makes whose abrasion resistance and the corrosion stability compete with each other in routine heat treatment and the surface in two kinds different characters salt bath protect technology ready-made tenfold rise. Be a technologys turn to have merit such as hardly becoming deformed , there being no the social effect of pollution , energy conservation at the same time. Our country expert studies after many years of experiment, unique salt bath formula developing out component finally on ones own, not only have broken the exclusive Germany Digaosha company international monopoly to this technology, and be more advanced than Germany in the field of environmental protection nothing social effect of pollution, reach level of international in the lead. That achievement the technology is advanced , the function is advantageous , mass stabilizes but catches with the person extensive consumer welcome, already big area is extended , is become the state-class priority new product, country priority extends a project during 95. And acquisition United Nations invents the award , national scientific and technological progress award being innovative , country environmental protection achievement rewards , Hubei province science and technology rewards , the Hubei province advance of science and technology rewards, ... And so on.

Technology characteristic
