whats hollow blow proucts ?
Hollow blow molding is to put the softened tubular thermoplastic blank extruded from the extruder into the molding mold, and then inject compressed air to make the blank deform along the mold cavity with the pressure of air, thus blowing into hollow products with short necks [2].
Hollow blow molding has been widely used to produce various thin shell hollow products, chemical and daily packaging containers, and children's toys.
Hollow blow molding (also known as blow molding) is a method that uses gas pressure to expand the hot melt parison closed in the mold to form hollow products. It is the third most commonly used plastic processing method, and also a rapidly developing plastic molding method.
Blow-molding grade plastics include polyolefin, engineering plastics and elastomer; The application of blow molding products involves automobile, office equipment, household appliances, medical and other aspects; It can produce 60000 bottles per hour and can also produce large blow-molded parts (up to 180kg). The multi-layer blow-molding technology has been greatly developed
