The process of blow molding products is generally as follows:
Preparation and transportation of raw materials - manufacture of moulded billets - blow, molding and cooling of moulded billets - dressing and quality inspection of products
Once a good molding method is selected, the molding process is basically determined.In addition, in mass production of blow molding products, should also consider the processing mode of operation and should be equipped with auxiliary equipment.
Operation methods: manual operation, semi-automatic operation, automatic operation.The following considerations should be taken into account when equipping auxiliary equipment.
(1) technical measures should be taken for drying of raw materials.
(2) treatment methods, recycling methods and technical requirements for corner wastes.
(3) temperature control of type blank reheating device.
(4) temperature control of blow molding or injection mold.
(5) drying of compressed air and selection of pressure
(6) cooling system for products after blow molding.
(7) methods of surface treatment and surface printing of blow molding products.
(8) quality of blow molding products (external dimension, pressure resistance, leakage resistance, environmental stress cracking resistance, etc.)
