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.

Blow molding machine is a very common mechanical equipment in the plastic machinery industry. Blow molding technology has been widely used all over the world. According to the manufacturing method of the parison, blow molding can be divided into extrusion blow molding, injection blow molding and hol

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
