The extrusion blow molding machine is equipped with a chiller for cooling and cooling, we call it an extruder chiller. Since the extruder is mainly used for various extruded plastic products, such as PE, PP, PVC, ABS, etc., the high temperature generated during the production process will cause difficult demolding and slow molding, so a chiller is required to provide low-temperature cycle freezing Water (5-30°C) is fed to the extruder to shorten the cooling time and improve product quality.

Blow molding can be divided into two blow molding methods, hollow and film. Hollow blow molding can also be divided into extrusion blowing, injection blowing, extrusion stretch blowing, injection stretch blowing and other molding methods. Today, I will briefly introduce the key points of extrusion blow molding design. The extrusion blow mold is mainly composed of two half molds, which are generally composed of a mold body, a mold cavity, a clamping blank, a guide post, etc. The main requirements for the mold structure design are as follows,

During the blow molding process, control the molding from four points of inflation pressure, blowing speed, inflation ratio, and inflation mold temperature.The extrusion blow molding process includes plastic melting and plasticization, extruding the tube blank, inflating the tube blank, cooling, opening the mold, taking out the product, trimming, and checking. The control of product molding can be carried out from the following four aspects.

Vacuum suction machine is the use of negative pressure principle, the material from the suction mouth into the silo, and then through the silo on/off valve control material discharge time, the whole work closed, can be controlled by intelligent computer, in line with the environmental protection pro

Before the new mold blow molding or the machine to replace other mold production, the mold test is an essential part.The result of the test will directly affect the smooth production of the factory.Therefore, it is necessary to follow reasonable operation steps and record useful technical parameters

Plastic chemical barrel is also called plastic chemical barrel, which is developed and blown by scientific formula, with diverse color and beautiful appearance, achieving the packaging index in acid and alkali resistance, corrosion resistance, leakage prevention, no fading, no deformation and so on.
