2.1 promotion and application of CAD, CAE and CAM Technology PP/PE/PC hollow profile sheet extrusion machine
2.2 application of digital high speed scanning system
At present, the application of digital system in plastic mold processing is less. The digital high-speed scanning system has the function of scanning the real object to produce the desired model. The application of digital high-speed scanning system in the plastic mold processing technology can effectively shorten the plastic mold development and design time and manufacturing cycle. In the near future, the digital high-speed scanning system can be quickly installed on the CNC machine tool of the plastic mold processing center, and the purpose of fast data acquisition can be realized by using the scanning probe head, such as Renishaw spz-1. Then, the data collected by the probe head is processed to form different formats of CAD data, which is applied in the plastic mold processing technology. The detection head of digital high-speed scanning system has the fastest scanning speed of 3m / min, which greatly shortens the processing cycle of plastic mold. It is believed that in the near future, digital high-speed scanning system will be widely used in plastic mold processing technology. PP/PE/PC hollow profile sheet extrusion machine handern.com
2.3 development and application of EDM milling technology
EDM milling technology is also known as EDM generation technology, which is developed from the traditional motor processing technology. EDM milling technology refers to the high-speed spindle of the machine tool drives the rod or tubular electrode to rotate, and uses multi axis linkage for EDM forming. In the process of using EDM milling technology to process plastic mold, it is not necessary to use complex shaped electrode. At present, a small number of foreign mold enterprises have applied EDM milling technology in plastic mold processing, and the effect is remarkable.
2.4 development of composite technology and superfine machining
With the continuous progress of nanotechnology, the processing technology of plastic mold began to develop in the direction of large-scale and precision. The processing precision of plastic mold can be controlled within 11nm. Nanotechnology combined with laser technology, ultrasonic technology, chemical technology and collector technology will be gradually applied in plastic mold processing technology. This kind of composite fine processing technology will be more and more popular among mold processing enterprises. PP/PE/PC hollow profile sheet extrusion machine handern.com
2.5 wide application of hot runner technology
The development speed of hot runner technology in foreign countries is faster than that in China. At present, some enterprises in China have tried to apply hot runner technology in plastic mold processing, and the effect is remarkable. Using hot runner technology to make plastic mold not only has good quality, but also can save resources to a certain extent, so hot runner technology will be widely used.
2.6 development of high pressure injection technology and gas assisted technology
Gas assisted technology is a new plastic mold processing technology in recent years. The plastic mold products manufactured by this technology not only have good surface quality, but also are not easy to be bent and deformed, which not only ensures the quality of the mold products, but also reduces the processing cost. It can be seen that gas assisted technology will become one of the important processing technologies of plastic mold. High pressure injection process can determine and control more processing parameters of plastic mold, so high pressure injection process will also be favored in the plastic mold processing industry.
2.7 application of high quality and economic processing materials
At present, the high price of processing materials is the main reason for the high overall price of plastic mold. According to relevant statistics, in the whole process of plastic mold processing, the cost of plastic mold processing materials accounts for 10% ~ 30% of the total cost. Therefore, reducing the cost of plastic mold processing materials can lower the market price of plastic mold. At present, there are some high-quality economic processing materials in the market. Mold enterprises should boldly apply these high-quality economic processing materials to plastic mold processing. On the premise of ensuring the processing quality of plastic mold, they should reduce production costs and improve profitability.
2.8 mold polishing tends to be intelligent and automatic
Surface polishing is the most difficult problem in the process of plastic mold processing. The surface roughness of plastic mold not only affects the overall appearance of the mold, but also affects the life of the mold. At present, manual hand grinding is still used to polish the surface of plastic mold in our country, which is not only time-consuming and labor-consuming, but also affects the quality of plastic mold. Therefore, mold polishing has the trend of automation and intelligence. Some people in Japan have developed an automatic CNC polishing machine, which can not only automatically polish the plastic mold, but also realize the intelligent polishing of the three-dimensional surface of the plastic mold.
