Siemens Motor Molding Extruder Equipment for HDPE EVOH AD Production Line Efficiency

An Extrusion Blow Molding Machine is a specialized piece of equipment designed to manufacture hollow plastic parts. The process begins by melting plastic resin, commonly materials such as HDPE, LDPE, polypropylene (PP), or PVC.

Once the plastic is melted, the machine extrudes it into a hollow tube known as a parison. This parison acts as the precursor shape which will be molded into the final product.

After extrusion, a mould closes around the parison. The machine then injects air into the hollow tube, causing the plastic to expand and take the exact shape of the mould cavity.

Finally, the molded plastic is cooled down to solidify its shape, and the finished hollow product is ejected from the mould, completing the extrusion blow molding cycle.

Extrusion blow molding is widely used for creating various containers and hollow objects, including:

• HDPE bottles for household items (detergents, shampoos, yogurt)
• Containers for motor oils and lubricants
• Chemical and pesticide bottles with durable construction
• Large jerry cans (5-30 liters capacity) for storage and transport
• Water tanks and fuel tanks requiring robust construction
• Various toys and hollow objects
• Plastic balls, floats, and cones in diverse shapes and sizes
