In the dynamic world of plastic manufacturing, HDPE (High – Density Polyethylene) extrusion blow moulding machines play a pivotal role. These machines are designed to transform HDPE resin into a wide variety of hollow plastic products, ranging from small bottles to large industrial containers. The manufacturers of these machines are at the forefront of innovation, constantly striving to improve efficiency, precision, and product quality.​

HDPE Extrusion Blow Moulding Machines Introduction:

HDPE extrusion blow molding machine is a kind of equipment specially used for high-density polyethylene (HDPE) plastic molding. It produces hollow products such as chemical barrels, large storage tanks, bottles and cans through extrusion-blow molding process. Its core processes include:

● Plastic melt extrusion: HDPE granules are heated and plasticized, and then extruded into tubular parisons.

● Mold closing and blow molding: The parison is placed in the mold and blown with high-pressure air to fit the mold cavity.

● Cooling and shaping: After the product cools, it is demolded and the production is completed.

Core Advantages of HDPE Extrusion Blow Molding Machine:

✔ High production efficiency: suitable for mass production (such as 200L chemical barrels).

✔ Strong material adaptability: can process recycled HDPE, in line with environmental protection trends.

✔ High product strength: HDPE’s impact resistance and chemical resistance are better than ordinary PE.

Application of HDPE Extrusion Blow Molding Machine:

● Chemical barrels & IBC barrels (acid and alkali resistant, corrosion resistant)

● Lubricating oil bottles & fuel containers (oil resistant, leak-proof)

● Detergent bottles & cosmetic bottles (high gloss, easy to shape)

● Food grade storage tanks (FDA certified)

● Agricultural water storage tanks (UV resistant)

● Large containers for construction (such as mortar storage barrels)
