![]() It mainly monitors and controls the running status, electrical system, heating system, temperature, and other aspects of the fully automatic extrusion blow molding machine, controls the step-less speed change of the DC motor of the extruder, the barrel heater, and the mold heater area. In addition, to a certain extent, it also controls the cold cutter and wall thickness control of the extrusion blow molding machine. The main control is the operation of the blowing needle, including pre-blowing, air blowing to the parison, and movement of the blowing needle. In this structure, after the parison is extruded, the air is blown into the parison to expand the parison close to the inner wall of the mold. Here plays a key role in the hydraulic system of the extrusion blow molding machine. The main function is to open, close, and clamp the mould, and control the movement of the mould on the blow station. Pinch sealing at the open end of the parison. Greatly improved the quality of multilayer extrusion blow molding products.Īpart from cutting off the excess parisons, the product can be taken out after it has been formed. Maybe you’ll get helpful something from it.Īs a blow molding machine manufacturer, Yankang breaks through the traditional die head design, develops a multi-layer die head, and is widely used in large size extrusion blow molding machines. If you have the same difficulty in blow molding machine wall thickness control, we prepare complete guidance of Blow Molding Wall Thickness Control. The wall thickness of extrusion blow molding products is also a headache for many manufacturers of blow molding products. ![]() Die HeadĬontrolling the parison to extrude uniformly, and controlling the wall thickness of the extrusion parison to be evenly distributed, especially for the production of multilayer extrusion blow molding products, the requirements for wall thickness are more stringent. ![]() Lay a good foundation for the production of high-quality plastic blow molding products. IKV Screw is an important Yankang extrusion blow molding machine part.Ĭompared with a traditional screws, the plasticizing efficiency is increased by 1.5 times, and the plasticizing effect is more uniform. Plasticizing these plastics requires the use of special screws for blow molding. The raw materials used in extrusion blow molding are generally HDPE, PE, PP, and so on. Its working principle is that the pressure and shear force generated by the high-speed rotation of the screw can make the raw materials fully mixed and plasticized. The core component of the extruder is the screw. Processing of plastic blow moulding raw materials, mainly plasticizing plastics. The parison enters the extrusion blow molding machine mold.Įxtrusion Blow Molding Machine Parts Name And Function Extruder The parison is extruded from an extruder. And what do parts for the machine?īefore understanding the extrusion blow molding machine parts name, let us first understand how the machine works?Įxtrusion Blow Molding Machine Manufacturing Process This blog will introduce the extrusion blow molding machine parts name.
