In the production process of extrusion blow molding machines, various problems are always encountered, such as insufficient blow molds. How can we solve some of the shortcomings?

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.

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.

The hollow blow molding machine is used to produce hollow products mainly made of HDPE plastic materials, such as oil drums, chemical drums, pesticide bottles and other special-shaped parts. How to properly use and maintain the hollow blow molding machine to extend its life?1. Inspection of machine
