Introduction of the classification and distinction of extrusion hollow blow molding machine

Before DEMAN MACHINERY has introduced the classification of hollow blowing molding machine, can be divided into injection blowing molding machine, extrusion blowing molding machine. Today we will want to share with you is the extrusion of hollow blowing machine classification introduction and difference. The classification basis of extrusion hollow blowing machine is according to the different feeding methods, thus divided into two types of continuous extrusion hollow blowing machine and intermittent extrusion hollow blowing machine two types. In the following content, we will introduce each type of device and the difference between them.

1. Continuous extrusion of plastic blowing machine

The feeding method is the extruder continuous extrusion of plastic tubular embryo. Advantages are: molding equipment is simple, easy to operate. The production process of continuous extrusion blow molding method has three reciprocating, rotation and rotary. Reciprocating continuous extrusion hollow blow molding machine billet is continuously extruded by the extruder, when the billet is long enough, the mold will be moved from the blowing machine cooling station to the head of the mold, clamp the blank, and then return to the blow molding station. Rotation feeding continuous extrusion hollow blowing machine more than a step, this step is to control the flow of melt, need to use a reversing valve at the front of the extruder to control, melt according to the order of the extruder of the billet on both sides of the extruder extrusion billet, to achieve continuous production.turntable continuous extrusion hollow blowing machine extruder continuous extrusion billet, the billet into the mold and is clamped, around the turntable axis of the transmission to the blowing, cooling, mold and take out the products and other stations.

2. Intermittent extrusion blow molding machine

Intermittent extrusion hollow blowing machine, also known as storage type hollow blowing machine. It is the extruder that constantly squeezes the melted plastic plastic embryo into a storage cavity, and the amount of extrusion is determined according to the amount of raw materials needed to produce a product. When the material in the storage cavity reaches the required quantity, the mold will close the mold for the next step. The advantage of intermittent extrusion hollow blowing machine is that the discharge is stable, fast feeding, product processing and production process is easy to control, especially suitable for the production of large plastic blowing products.

DEMAN MACHINERY is an equipment manufacturer focusing on the production of storage type of large hollow blowing machines. Equipment supports the production of plastic trays, IBC ton bucket, double ring bucket, large plastic water tank bucket, solar inner tank, mobile toilets, septic tanks, plastic table panels, kayaks, etc. Equipment using IKV screw, electromagnetic induction heating, infrared heating, can quickly and effectively complete the heating and melting of raw materials; stable extruder equipment, to ensure the stable and uniform raw material transmission, pressurized cylinder, to ensure a strong mold locking force......
