subject: Blow Molding Machine And Injection Molding Machine [print this page] Now, blow molding machine and injection molding machine are more and more widely used, such as packaging, plastic packaging process, as well as gifts and toys.
After the liquid plastic spray to use the machine out of the wind blowing, blowing the plastic body attached to a certain shape of the cavity, which made the product, this machine is called blow molding machine. Plastic in the screw extruder is melted and quantitative extrusion, molding and then through the mouth membrane, and then cooling wind ring hair, then there is a certain speed traction traction machine, winding machine to be wound into roll. Injection molding machine is to use plastic or thermoset material made of plastic mold plastic products of various shapes of the main molding equipment. It is divided into vertical, horizontal, and all-electric. Function of heating the plastic injection molding, to exert pressure on the molten plastic to injection and full of mold cavity.
Blow molding machine can be divided into extrusion blow molding machines, injection blow molding machine and the special structure of the blow molding machine. Stretch blow molding machine can be attributed toeach of these classes. Extrusion blow molding machine is extrusion blow molding machine and the machine body harmony mode combination. It is components by the machine and parison extrusion die, Inflation device, the mold body parison thickness control system and transmission. Injection molding machine is combination of machine injection molding machine and blow institutions. Including plastics, hydraulic systems, control electrical appliances and other mechanical parts. Injection blow molding machine producing precision plastic container size, nosecondary processing, but the tooling cost is higher. Blow molding machine is the special structure sheet, cold billet of molten material and blow molding the parisonshape and uses a special hollow body blow molding machine. As the production of products, shapes and requirements are different, different structure of the blow molding machine.
Usually by the injection molding machine system, clamping system, hydraulic system, electrical control systems, lubrication systems, heating and cooling systems, security monitoring systems and so on. The working principle of injection molding machine and injection with a syringe similar to it with the screw (or plunger) of thrust, will have a good molten plastics vertical injection molding machine (ie viscous flow) of the plastic injected into the closed good mold cavity, the shape after the curing process to obtain products.
