Mold is the main process equipment for industrial production. The development of modern industrial products and the improvement of technological level, to a large extent, depends on the level of development of the mold industry. Since the Second World War, the improvement of automation has led to the rapid development of foreign moulds. Although China is a large country of mould making, it is not a powerful country in mould manufacturing. This is the key to the quality of the spring that matches the mold. Affect the performance of the whole mold.
本人是從事表面處理工程專業，對模具彈簧也就是矩形彈簧的表面處理作了市場調查。發覺如下問題，提出來討論。 彈簧表面采用各種漆層來代作識別，如輕小荷重用黃色漆表示;輕荷重用藍色漆表示;中荷重用紅色漆表示;極重荷重用咖啡色漆表示; 性能分析:好的漆層來配套彈簧表面處理，可謂一舉兩得，用顏色來標識各種技術參數，方便工業生產操作，而且使彈簧表面的防腐性能得以更好的保證。 目前成功使用上述方式的主要廠家為國外廠家多，如日本東發公司等。
I am engaged in surface treatment engineering, the mold spring is also rectangular spring surface treatment market research. Find the following questions and discuss them. The spring surface is identified by various paint layers, such as yellow paint for light and small loads, blue paint for light loads, red paint for medium loads, coffee paint for extreme loads, and performance analysis: a good paint layer for supporting spring surface treatment can be said to kill two birds with one stone, and color can be used to identify various technical parameters. The production operation, and make the surface corrosion resistance of the spring better guaranteed. At present, the main manufacturers that successfully use the above methods are many foreign manufacturers, such as Japan Eastern hair company.
在國內，此還只有小部分廠家效訪，目前主要是一些固定的技術要求，如采用進口材料而達到國外水平外，但整個彈簧表面處理效果卻明顯存在差距。 國內一般用人工噴漆，外觀會出現流掛、漏噴、結合不好，防銹能力差。本身的工藝局限性造成大量的產品要脫漆返工。
At home, only a small number of manufacturers visited, at present mainly some fixed technical requirements, such as the use of imported materials to achieve foreign standards, but the whole spring surface treatment effect is obviously different. Generally used in domestic spray paint, the appearance of flow hanging, leakage spray, combination is not good, rust prevention ability is poor. The limitations of its technology cause a large number of products to be stripper and rework.
