High-gloss non-marking injection mold temperature machine (abbreviation) Introduction: high-light mold temperature machine
The high-gloss non-marking steam injection mold temperature machine uses high-temperature steam or high-temperature hot water. When the injection molding machine is closed, it is blown into high-temperature steam or high-temperature hot water. First, the mold temperature is raised to a set value, and then the plastic injection molding is started. After the injection molding machine completes the pressure-holding and cooling, the cold water is injected, the mold temperature is quickly lowered to a set value, and the mold is opened, and then the air is blown into the mold to completely blow away the cold water to complete the entire injection molding process. The newly developed high-gloss non-marking injection mold temperature machine of Ode Zui has a high-temperature hot water machine and a freezer, and adds a hot water and cooling water recovery system. The energy saving effect is remarkable and the profit is considerable. This is the advantage of the Oude high-light mold temperature machine . : Zhang Wanli Seamless injection molding
The shortcomings of traditional injection mold temperature control are as follows:
1 can not meet the needs of rapid heating and rapid cooling in high-gloss injection molding.
2 The temperature rise is small, and the weld marks on the surface of the product can only be reduced and cannot be eliminated.
3 The higher the hardness of the plastic, the worse the fluidity. Therefore, with this process, the hardness of the surface of the product can only reach the HB level, which cannot meet the needs of actual use.
4 When the mold heats up, it expands by heat, and when it cools down, it shrinks again, making the clamping force very unstable. It is easy to cause various defects such as product dissatisfaction and high internal stress.
