Custom household appliances injection molding

Plastic shrinkage and its influencing factors The characteristics of thermoplastics are that they expand after heating, shrink after cooling, and of course the volume will shrink after pressurization. In the injection molding process, the molten plastic is first injected into the mold cavity, and after the filling is completed, the melt is cooled and solidified, and shrinkage occurs when the plastic part is taken out from the mold, and the shrinkage is called forming shrinkage. The size of the plastic part will still change slightly from the time the mold is removed to the stable state. One change is to continue shrinking. This shrinkage is called back shrinkage. Another variation is that some hygroscopic plastics swell due to moisture absorption. For example, when the water content of the nylon 610 is 3%, the dimensional increase is 2%; and when the water content of the glass fiber reinforced nylon 66 is 40%, the dimensional increase is 0.3%. But the main role is the forming shrinkage.
