In addition, maintaining pressure and time also have a great influence on contraction, and when pressure is high and time is long, contraction but direction is great. The injection pressure is high, the melt viscosity difference is small, the interlayer shear stress is small, the elastic rebound after demoulding is large, so the shrinkage can also be reduced, the material temperature is high, the shrinkage is large, but the direction is small.
Blow molding machine is the liquid plastic spray, the use of the machine blowing out of the wind, the plastic body blowing to a certain shape of the cavity, so as to make products, this machine is called blow molding machine. Is also a blowing bottle machine from a broad interpretation of the blow molding machine is also a blowing bottle machine. Bottle blowing machine includes blow molding machine, hollow molding machine, injection blowing machine and now used more two step blowing machine.
This blow molding machine removes part of the air (oxygen) from the packaging container, which can effectively prevent food spoilage. The plastic bottle blowing machine adopts good barrier (air tightness) packaging materials and strict sealing technology and requirements, which can effectively prevent the exchange of packaging contents and substances, so as to avoid food weight loss, tastiness, and prevent secondary pollution. The gas inside the container of plastic blowing bottle machine has been eliminated, which accelerates the conduction of heat, which can improve the efficiency of hot sterilization, but also avoid the rupture of the packaging container due to the expansion of gas when heating sterilization. In the food industry, plastic bottle blowing machine application is very common, all kinds of cooked products such as chicken legs, ham, sausage, etc. Pickle products such as various pickles and soy products, preserved fruit and other foods that need preservation are more and more used in plastic bottle blowing machines.
After plastic bottle blowing machine, the food preservation period is long, greatly extend the shelf life of food. The development direction of injection blowing hollow plastic molding machine is to shorten the molding cycle, improve the productivity of single die, reduce the downtime of die changing, improve the blow molding speed, optimize the heat transfer system, and improve the output.
