Plastic Toy Ball Blow Molding Machine

2025-10-27

Plastic toy ball blow molding machine is an automated plastic molding equipment specifically designed for producing hollow plastic toy balls (such as ocean balls, bouncy balls, hollow soccer/basketball models, etc.). The core process of plastic blow molding machine for plastic toy balls involves heating and melting plastic to form a parison, then inflating it with compressed air, allowing it to cool and solidify against the inner wall of a mold, ultimately obtaining the desired hollow sphere.

Components of Plastic Toy Ball Blow Molding Machine:

1. Extrusion system: Includes a hopper, screw, and barrel. Responsible for heating, melting, mixing, and uniformly extruding plastic granules (such as HDPE) to form a tubular parison.

2. Mold system: Typically consists of two halves (clamping mechanism), with the shape and surface texture (such as seams and patterns) of the sphere engraved inside. The precision of the mold directly determines the quality and appearance of the product.

3. Clamping mechanism: A powerful hydraulic or mechanical device used to quickly and forcefully open and close the mold, maintaining sufficient clamping force during the blow molding stage to prevent the mold from being forced open by air pressure.

4. Blow Molding System: Includes air injection needles, air lines, and control valves. After the mold closes, the air injection needles insert into the parison, injecting compressed air to force the molten plastic to adhere tightly to the inner wall of the mold.

5. Electrical Control System: PLC (Programmable Logic Controller) and touchscreen human-machine interface, used for precise control of parameters such as temperature, pressure, time, and speed throughout the production cycle.

6. Hydraulic/Pneumatic System: Provides power for machine movement (such as mold closing and screw rotation) and blow molding.

7. Cooling System: The mold usually has cooling water channels, which circulate cooling water to accelerate the cooling and solidification of the plastic, shortening the production cycle.

Maintenance and Care of Plastic Blow Molding Machine:

1. Clean the surface of the blow molding machine and check for leaks in the air and oil lines.

2. Change the hydraulic oil and filter regularly.

3. Clean or replace the mold to prevent residual plastic from affecting product quality.

4. Check and tighten all screws.

5. Lubricate moving parts (such as guide rails and guide pillars).
