Multi-layer blow molding process of the  Large Multi-Layer Blow Molding Machine 

1. Process Overview:

Multi layer blow molding is actually a kind of plastic processing technology that extruding different kinds of plastics through multiple extruders, and then extruding the forming billets through the same head, and then making various multi-layer hollow containers.

2. Composite plastic combination method:

PA/PO HDPE/PVC/HDPE PVA/HDPE PS/PAN/PP

3, purpose and function:

It has better container tightness and can meet the requirements of special liquid clothing. For example, the special requirements of tons of barrels, water tanks and other products.

4. Technology key:

Whether the bonding method between different layers of plastic parison is proper is the key to improve the yield. There are two commonly used methods:

(1) a resin mixed with bonding properties.

2. Add the bonding material layer. This method requires the equipment to be more complex.

5. The form of blow molding:

(1) Co extrusion blow molding:

The co extrusion blow molding method can improve the performance of the products, increase the transparency of the products, and increase the mechanical strength. However, due to the need to integrate completely different plastics, the process control is complex and the cost is increased.

(2) multi-layer injection molding:

After forming the first layer on the male mould, the die cavity is changed into second layers and third layers on the first layer, and finally the blow molding is formed. It is characterized by no waste edges and no cutting marks.
