With the progress of hollow blow molding technology, especially the development of large-scale hollow molding equipment, multi-layer coextrusion hollow molding technology and equipment, it has driven the new development of other hollow molding technology. Today, Jinchang introduces the molding technology of plastic hollow containers to witness the manufacturing progress of plastic bottles.
In the development of hollow plastic molding machine in China, extrusion blow hollow plastic molding machine is a fast developing and perfect model. Modern new development is mainly reflected in three-dimensional blow molding of complex hollow containers and large packaging containers.
Three dimensional blow molding usually uses a 6-8-axis manipulator to transport the parison and place it in the blow molding mold for blowing, while the large-scale hollow blow molding technology belongs to the extrusion technology. The machinery generally includes extruder, head, mold closing device, blowing device, parison wall thickness control system, product taking out device, hydraulic station and strong weak electric control system.
