Injection molding is the melted plastic injected into the molding die, through the water-cooled demolding, low-pressure injection molding is the use of special hot melt adhesive, the hot melt adhesive flow performance is good, do not need to increase the pressure can be injected into the mold, will not be due to high temperatures and high pressures to harm the components of the reserved molds, injection molding in the traditional sense, there is a difference between the traditional molds is a steel mold and low-pressure molds can be molded in aluminum, but the raw materials of low-pressure injection molding to go to the high The choice is small.
Blow molding process is the production process of plastic film, blow molding is the melted plastic raw materials through the ring mold, stretched into a cylinder, generally thinner, the thickness of less than 0.25MM, as if it were a long strip of balloons, film bubbles leave the film lip through the wind ring blowing wind cooling, flattening and winding up into a cylinder material.
Below the injection molding is a new process in the injection molding industry, blown film is a traditional manufacturing film process, generally a different factory production, no correlation.
