The three main types of blowing machine equipment performance

How can modern people's daily life be separated from the plastic bottles, and how can there be bottles without blowing machine? Today we will learn about the three main properties of the blowing machine equipment.

Extrusion blowing machine is a combination of extruder and blowing machine and die closing mechanism, consisting of extruder and blank die head, blowing device, die closing mechanism, blank thickness control system and transmission mechanism. Blank die head is one of the important parts to determine the quality of blown products, usually there are side feed type die head and central feed type die head.

When blowing large products, the die head is mostly used to store the material cylinder. The volume of the accumulator cylinder is 1kg and up to 240kg, and the thickness control device is used to control the wall thickness of the billet, and the control point is up to 128 points, generally 20-30 points. Extrusion blow molding machine can produce hollow products in the volume range of 2.5ml~104l.

Injection blow molding machine is the combination of injection molding machine and blowing mechanism, including plasticizing mechanism, hydraulic system, control electrical and other mechanical parts. The common types are three-station injection blowing machine and four-station injection blowing machine. The three-station machine has three stations of preform, blowing and demolding, each station is 120° apart. The four-station machine has one more preforming station, each station is 90° apart. In addition, there are also duplex injection blow molding machines with 180° separation between stations. The injection blow molding machine produces plastic containers with precise dimensions and without secondary processing, but the mold cost is higher.

Special structure blowing machine is a blowing machine that uses sheet, molten material and cold blanks as the type blank to blow bottles with special shapes and uses of hollow bodies. Due to the different shapes and requirements of the products produced, the structure of the blow molding machine also varies.

Selecting a blow molding machine, hollow blow molding machine manufacturers believe that the bottle can be selected according to the different requirements of the bottle, because the blow molding machine equipment each has its own performance characteristics.
