The innovation unification correspondence could effective addressing Manufacturing firm information system question the unification correspondence be able to satisfy many profession pain spots the government request, the solution method validity already to appear. 1) during management development, solution information system's effective application and coordination. The manufacture profession industry chain span is big, the information isolated island phenomenon is serious, the manufacturing industry common characteristic is the product craft is complex, the process of manufacture is long, the product and the material variety specification are many, the cooperation based on division of labor is high. Its information current capacity and information application management difficulty and complex, for instance takes seriously to produce the scene operational practice, the attention product informationization, to rely on the inside and outside integrated the supply chain management and so on. Should carry on view of this phenomenon Manufacturing firms its core business the conformity, with the aid of the information fusion promotion enterprise swift development, for example ERP and the unification correspondence fusion may raise the staff production efficiency, CRM and the call center fusion may well for customer service and so on. Through the higher electronic information, the automatic control, the modern management, the advanced manufacture and so on many technical and the IT technology and communication's fusion, enables the Manufacturing firm to be able simultaneously to regulate the physical distribution, the fund class, the information flow, carries on the entire journey monitoring to the product quality, thus improves the product quality and the labor productivity effectively, reduces the production cost, thus realizes the manufacturing industry high added value finally and not suitably by vicariousness. 2) simplifies communications system's investment construction, the enhancement investment rate of return. Different organization's increase enlarges with the space length can cause the communications system investment enlargement, many kinds of form's communications will need also the plant expansion correspondence expense disbursement, the unification correspondence exactly to be possible find through the communication and the IT technology organic fusion for the enterprise the effective solution, this was precisely the current Manufacturing firm solves the development pain spot to need

表面处理工艺的英文缩写是ST（Surface treatment）。表面处理在基体材料表面上人工形成一层与基体的机械、物理和化学性能不同的表层的工艺方法。表面处理的目的是满足产品的耐蚀性、耐磨性、装饰或其他特种功能要求。
对于金属铸件，比较常用的表面处理方法是，机械打磨，化学处理，表面热处理，喷涂表面，表面处理就是对工件表面进行清洁、清扫、去毛刺、去油污、去氧化皮等。
扩展资料
为了把物体表面所附着的各种异物（如油污、锈蚀、灰尘、旧漆膜等）去除，提供适合于涂装要求的良好基底，以保证涂膜具有良好的防腐蚀性能、装饰性能及某些特种功能，在涂装之前必须对物体表面进行预处理。人们把进行这种处理所做的工作，统称为涂装前（表面）处理或（表面）预处理。
如刮刀、钢丝刷或砂轮等。用手工可以除去工件表面的锈迹和氧化皮，但手工处理劳动强度大、生产效率低，质量差，清理不彻底。
化学处理主要是利用酸性或碱性溶液与工件表面的氧化物及油污发生化学反应，使其溶解在酸性或碱性的溶液中，以达到去除工件表面锈迹氧化皮及油污，再利用尼龙制成的毛刷辊或304#不锈钢丝耐酸碱溶液制成的钢丝刷辊清扫干净便可达到目的。
化学处理适应于对薄板件清理，但缺点是：若时间控制不当，即使加缓蚀剂，也能使钢材产生过蚀现象，对于较复杂的结构件和有孔的零件，经酸性溶液酸洗后，浸入缝隙或孔穴中的余酸难以彻底清除，若处理不当，将成为工件以后腐蚀的隐患，且化学物易挥发，成本高，处理后的化学排放工作难度大，若处理不当，将对环境造成严重的污染。随着人们环保意识的提高，此种处理方法正被机械处理法取代。
