Extrusion blow molding machine & auxiliary machines

Extrusion blow molding machine

Extrusion blow molding machine is a machine that can make plastic products. First, the raw material is heated to complete plasticization, extruded through an extruder to form a tubular parison, injected into the mold, compressed air is introduced into the mold, the parison is inflated, adhered to the inner wall of the mold, and finally demolded after cooling , to obtain a variety of hollow plastic products.

So what does it do? Generally, the raw materials are injected into the mold. If there is a problem with the mold, the plastic products produced are waste products.

Because the blow molding machine mold will heat up during the production process, in order to ensure the quality of the plastic products, the mold should be cooled, so that the product has a smooth and flawless skin, reduce the surface marks and internal stress of the product, and ensure the appearance of the product. Convenient demoulding also improves production efficiency.

There is stored gas in the gas storage tank, mainly to ensure the stability of the output air pressure and reduce the temperature of the air duct. It is also a cleaner, which will partially clean up water, dust and impurities to ensure the stability of the gas.

Cooling tower

In the production process of the blow molding machine, heat will be generated, which is to cool the blow molding machine and reduce the temperature of the water, thereby cooling the mold and speeding up the cooling speed of the mold.

It is to mix the raw materials fully and evenly. This step cannot be underestimated. Only by mixing evenly can the wall thickness distribution and quality of the blow molding machine products be guaranteed.



Dry and dehumidify the compressed air used for blow molding to ensure the quality of compressed air and improve the quality of blow molding products.

Its function is to smash the leftovers and wastes of blow molding products into plastic particles for repeated recycling, which is environmentally friendly and saves costs.
