Cosmetics cosmetics packaging hose production mold cooling technology

Cosmetics cosmetics packaging hose production mold cooling is a key technology. Cosmetics cosmetics packaging hose production mold wall edge plastic skin effectively isolate the core layer, so as to make the heat transfer is very slow. Cosmetics cosmetics packaging hose production mold cooling, however, often to the final stages of design to pay attention to. Good cooling design style can be reduced 20% 30% or the shorter cycle of production, and improve labor productivity.
in the production cycle, cosmetics cosmetics packaging hose production mold surface temperature periodic changing unceasingly, when hot melt presses the mould wall, die temperature is high, after ejection parts, injection before next time, empty cavity of the mold temperature is low. To cooldown reduced to the lowest limit, people have been exploring to produce qualified parts of minimum cosmetic soft hose cosmetics packaging production mold temperature. Mold temperature is one of the important role that affect the melt flow within the cavity size and the size of the proportion between skin and core layer. The lower mold temperature, the thicker the skin size the greater the pressure drop inside the cavity. Line of arteries and veins is cooling technology in plastic injection into the mold cavity, usually adopt circulating cooling cosmetics packaging tube very frozen frozen liquid to adjust cooling technology.
