Qingyuan County Zhanzhuang National Day Mold Processing Factory

Manhole cover molds are increasingly widely used in rural planning and road construction. In the next few years, as my country's economy continues to develop rapidly, the country will gradually phase out all cast iron manhole covers and replace them with composite material manhole covers. In addition, through market promotion and continuous improvement in recent years, our factory has perfected the complete set of manhole cover mold equipment, which is unsaleable all over the country. Manhole cover molds with reasonable design of production equipment and manhole cover molds with advanced technology and various performance indicators have reached the level of similar products at home and abroad. The material is the basic mold. The shape is supported by the foundation. So what aspects should be paid attention to when choosing manhole cover mold materials? Molds with large parts output and stable appearance and dimensions should be made of high-performance materials. Such mold materials can also be processed with low vacuum surface strengthening. Improve the durability of the mold to a new level. The shape of the mold is complex and precise, requiring high manufacturing cycles and a long manufacturing cycle. The processing cost of the mold far exceeds the material cost of the mold. This mold should also be made of high-performance materials. High-stress molds are made of high-performance materials and can use inexpensive surface strengthening techniques to improve their durability. Molds with a small output of parts have simple shapes, low stress, and are easy to manufacture. Molds that are frequently modified can be made of ordinary steel, cast iron or even non-metallic materials. Mold material selection should be based on national resources and use my country's element-rich steel grades. It is necessary to select materials from the perspective of sustainable development and use new steel grades as much as possible to convert scientific research results into productivity and improve the quality of molds. Correctly view the development of domestic mold materials. The castings are of good quality and have low interest rates. The material is suitable for all sizes, and the dimensional accuracy is high. The appearance is smooth and clean, which reduces cleaning and saves machine processing. Internal defects greatly reduce the density of the structure. Large-scale and mass production can be achieved. Automated assembly lines are environmentally friendly. It can greatly improve the working environment, reduce labor intensity and reduce energy consumption.
