Extrusion blow molding machine is one of the important equipment parts of plastic hollow products. It can produce a variety of plastic blow molding products. During the production process, some products need to control the wall thickness problem, so how to control the wall thickness?

Extrusion blow molding machine for plastic milk bottle jugBecause there are many kinds of milk with different characteristics, different packaging also appears to meet the characteristics of the product itself and market demand. At present, there are three kinds of plastic packaging bottles for milk

IBC ton barrel refers to IBC medium-sized bulk container, which is an essential tool for modern storage and transportation of liquid products. The container is composed of an inner container and a metal frame, and is blow-molded with high molecular weight and high density polyethylene, which has high strength, corrosion resistance and good hygiene.

Blow molding machine working principle: similar to blowing bubbles, the preferred resin to join the extruder, make it melt, through the ring hole into a closed end of the thin-walled round billet, and then through the compressed air, so that the blowing to the required thickness and width.Therefore,

1.A plasticizing system 2. Maintenance of special hydraulic system for wall thickness control 3. hydraulic system 4. Regular injection of extreme pressure lubrication oil

For fully automatic hollow blow molding machines, there are basically two typical designs, one is called the flexible ring type, the other is the mouth edge repair form.(1) Flexible ring technology Flexible ring type is through electro-hydraulic servo control thin-wall flexible ring in one direction
