  • Detail

The rapid development of China's mold industry has become an old topic in the industry. When Toyota Motor plans to realize the commercialization of solid-state lithium batteries in 2022, the electrothermal mold dominated by electric heating, such as bottle blowing mold and hot runner system, is also updating very quickly

insiders said that due to the limitations of the domestic traditional alloy electric heating product process, its price is bound to fall further. The utilization rate of mold heating elements is very low, and the heating elements need to be replaced frequently. Many domestic manufacturers have begun to look for higher quality electric heating elements, and have tried to use alumina ceramic heating elements as a new generation of mold heating elements

after a lot of efforts, Zhuhai Huiyou Electronics Co., Ltd. has successfully developed dozens of electric heating tubes for general use in molds, which have been very competitive in practical use: the heating time of molds has been reduced by more than 50%; The heating speed of metallized ceramic heater is faster than that of traditional stainless steel heater. Generally, when stainless steel electric heating pipe is used for heating, heat is transferred from the heating wire line to magnesium oxide powder, and then the stainless steel pipe wall is heated by magnesium oxide powder. In this process, a large amount of heat from the heating wire has been wasted, so the heating temperature of general metal electric heating pipe is relatively low. The ceramic electric heating tube directly transfers heat from the heating wire to the ceramic tube, which can directly heat the die steel, greatly reducing the heating time of the die. In addition, the electric heating tube made of alumina ceramics not only shortens the heating time of the mold as a whole, but also has a higher power density. At the same time, the die damage rate is reduced by 90% and the service life of the heating tube is improved. Experts said that the new electric heating tube has many advantages and has become a new favorite in the domestic mold industry

this point has a great meaning:
