Processing technology of veterinary vaccine bottles-extrusion and blowing

Veterinary vaccine bottles Plastic bottles are mainly used to contain inactivated vaccines. In the processing method, squeezing and blowing is a commonly used process.

Extrusion blow, that is, extrusion blow molding. First, the extruder extrudes the tubular parison. After the extruder melts and plasticizes, the material is extruded from the die; then, the parison is clamped and closed when the parison arrives. Cut off a section of tube embryo while it is hot and place it in the blow mold, close the mold and clamp it at the same time; after that, inflate the parison, and blow compressed air into the parison through the blow nozzle to inflate the parison The precise shape of the molding cavity; after molding, the mold is opened to take out the veterinary vaccine bottle.

Extrusion blow molding is an earlier type of blow molding method in the current plastic product molding method. The molding equipment is simple and easy to operate, and the choice of raw materials is wider. Suitable for blow molding of PE, PP, PVC, PETG, thermoplastic engineering plastics, thermoplastic elastomers and other polymers and various blends.

With the increasing maturity of the extrusion blow molding process, the products produced are more widely used. In addition to processing veterinary vaccine bottles, other blow-molded products include balls, toys, automobile fuel tanks, door frames, racks, clay pots and other packaging containers, storage tanks and other industrial parts.
