Several changes in the precision mold industry
Precision mold industry of several changes into the 21st century, China has become a large mold manufacturing country, 2009 sales volume has been close to 100 billion yuan, mold imports have been nearly 2 billion U.S. dollars, still maintain four consecutive years 20 billion U.S. dollars import level; mold exports close to 1.9 billion U.S. dollars, is also basically the same as in 2008. Mold export destination of the most countries and regions in order for Hong Kong, the United States, Japan, Germany, India, exports of molds to the export source points mainly from Guangdong, Zhejiang and Jiangsu, followed by Shanghai, Shandong, Tianjin, Fujian, Liaoning, Beijing and Jilin; mold import source of the most countries and regions in order...

Mold design process requires precision
Mold design process requires accurate mold, we are not unfamiliar, but how many people understand the manufacture of molds! Here is a brief introduction to you about the manufacture of molds. Mold design and production requirements are: precise size, surface clean; reasonable structure, high production efficiency, easy to automate; easy to manufacture, high life, low cost; design to meet the needs of the process, economic and reasonable. The structural design and parameters of the mold should take into account such factors as rigidity, directivity, unloading mechanism, positioning method and gap size. The wearable parts on the mold should be easy to replace. For plastic and die-casting molds, it is also necessary to consider reasonable pouring system, molten plastic...

What is the inspection method of mold making?
Mold production inspection method is what 1, macroscopic inspection chemical composition to ensure the performance of steel is decisive, but the composition of qualified, can not be a comprehensive description of steel performance, due to the internal organization of steel and composition of the unevenness, macroscopic inspection to a large extent to supplement the shortcomings of this area. Macroscopic inspection can observe the crystallization of the steel, the disruption of the continuity of the steel and the inhomogeneity of certain components. The standard "Structural Steels with Low Frequency Tissue Defects Grading Chart" GB1979 macroscopic commonly seen eight defects: segregation, looseness, inclusions, shrinkage, blisters, white spots, cracks, folds. 2, annealing tissue assessment annealing for the purpose of reducing the steel...
