The jerry can blow molding machine is a type of blow molder that extrudes a molten plastic tube (called a parison), captures it within a two-part mold shaped like a jerry can, and then inflates it with air so it takes the mold’s shape. The entire process: from raw plastic pellet to finished, hollow jerry can is automated.

Components of Jerry Can Blow Molding Machine:

1. Hopper: Holds the raw HDPE plastic pellets (often mixed with color masterbatch).

2. Heated Barrel & Screw: The screw rotates, conveying, melting, and compressing the plastic into a homogeneous melt.

3. Die Head: Shapes the molten plastic into a precise, downward-hanging tube (the parison).

4. Molds: Two hardened steel halves that have the precise negative shape of the jerry can, including handle details, ribs, and embossed text.

5. Clamping Mechanism: A powerful hydraulic or electric system that slams the mold halves together with immense force to seal the parison.

6. Blow Pin System: A pin or needle enters the parison and injects high-pressure air, inflating the soft plastic against the cold mold walls.

7. Hydraulic/Power System: Provides the energy for clamping, extrusion, and movement.

8. Control Panel (PLC/HMI): The brain of the extrusion blow molding machine, where an operator sets and monitors all parameters (temperature, timing, parison profile).

Why Extrusion Blow Molding Machine is Perfect for Jerry Cans?

1. Seamless & Hollow: Creates a strong, one-piece, leak-proof container—essential for storing fuels and chemicals.

2. Complex Geometry: Easily forms the integrated handle, spout, and reinforcing ribs.

3. Material Efficiency: HDPE is ideal for blow molding and provides excellent chemical resistance and durability.

4. High Production Rate: A extrusion blow molding machine can produce hundreds of jerry cans per hour.
