What is the future development trend of plastic molds?

In many industrial and daily life products, molds are an indispensable part of Dingxi. Many industrial products, including daily necessities, are completed by molds. In modern mass production, there will be no high-quality products without high-level molds. It also plays an important role in improving production efficiency and reducing production costs for enterprises. According to the latest foreign statistical analysis, 75% of the rough machining of metal parts, 50% of the finishing machining and 90% of the plastic parts are processed by molds. Therefore, the mold industry is also called "Crown Industry". Today, mold manufacturing has become an important part of advanced manufacturing technology.

Plastic molds are an important field in the mold industry. The emergence of high-speed processing technology has opened up a new path for plastic mold manufacturing technology. To replace electrical machining with high-speed machining as much as possible is an inevitable trend to speed up mold development and improve mold manufacturing quality.

The main advantages of high-speed machining are:

Good product quality-high-speed cutting processes parts at a cutting speed that is about 10 times higher than the conventional cutting speed. The residual material of the blank material is cut away from the workpiece in an instant before it can be fully deformed. The residual stress on the surface of the workpiece is very small; Most of the heat (more than 95%) generated in the cutting process is quickly taken away by the chips, and the thermal deformation of the workpiece is small; during the high-speed machining process, the machine tool spindle runs at a very high speed (10000"80000 r/min) to excite vibration The frequency is far away from the natural frequency range of the "machine tool-tool-workpiece" system, and the machining process of the parts is smooth and impact-free. Therefore, the machining accuracy of the parts is high, the surface quality is good, and the roughness can reach Ra 0.6μm or more. After high-speed milling The surface quality of the cavity can reach the level of grinding, so many subsequent finishing processes can often be omitted

High production efficiency-using high-speed machining center or high-speed milling machine to process the mold, the rough and fine machining of the cavity and the machining of other parts of the mold parts can be completed in one clamping of the workpiece, which is the so-called "one pass" technology (One Pass Machining) ), the cutting speed is very high, and the efficiency of the machining process itself is several times higher than that of electrical machining. In addition, it does not need to be an electrode, and often does not require subsequent manual grinding and polishing, and it is easy to automate the processing process. Therefore, the application of high-speed processing technology has greatly increased the development speed of molds.

Since the development of my country's plastic mold industry, rapid progress has been made. The design and manufacturing technology of plastic molds, CAD and other related technologies have been studied in depth in my country. However, under the situation that the quality of domestic molds is uneven due to the different process conditions used by plastic mold manufacturers, modern enterprises need to increase the research efforts of plastic molds. Plastic molds play a huge role in industries such as machinery, electronics, automobiles, information, aviation, aerospace, light industry, military industry, transportation, building materials, medical treatment, biology, and energy.
