Introduction and distinction of extrusion blow molding machine

Introduction and distinction of extrusion blow molding machine

HUAN Machinery Have introduced the classification of hollow blowing machine, can be divided into injection blowing machine, extrusion blowing machine. Today I will share with you the classification and difference of extrusion blow molding machine. The classification of extrusion blow molding machine is based on the different feeding methods, which is divided into two types: continuous extrusion blow molding machine and intermittent extrusion blow molding machine. In the following content, we will introduce each type of device and the differences between them.

1. Continuous extrusion of hollow plastic blowing machine

The discharge method is the extruder continuously extruding the plastic tubular embryo. Advantages are: the molding equipment is simple, easy to operate. The production process of continuous extrusion blow molding method has reciprocating, rotation output type and rotary type. Reciprocating continuous extrusion The hollow blowing machine is continuously extruded by the extruder. When the blank is long enough, the mold will be moved from the cooling station of the blowing machine to the bottom of the head, holding the blank, and then return to the blowing station. Rotation and discharge type continuous extrusion blow molding machine more than a step, this step is to control the flow of the melt, the need to use the reversing valve at the front end of the extruder to control, the melt according to the sequence through the billet head on both sides of the extruder extrusion billet, to achieve continuous production. Rotable continuous extrusion blow molding machine extruder continuous extrusion billet, type of the mold into the mold and is clamped, around the turntable axis in turn to the blowing, cooling, open mold and remove products and other stations.

2. Intermittent extrusion blow molding machine

Intermittent extrusion blow molding machine, also known as storage type hollow blowing machine. Is the extruder constantly will melt plasticized plastic embryo into a storage cavity, the amount of extrusion is determined according to the amount of raw materials needed for the production of a product. When the material in the storage chamber reaches the required quantity, the mold will close the die and take the next step of forming. The advantages of intermittent extrusion blow molding machine lie in the stable discharge, fast feeding, easy to control the product processing and production process, especially suitable for the production of large plastic blowing products.
