The ABA film blowing machine, compared to a single-layer machine, offers higher production efficiency and better film quality. This is due to the ABA film blowing machine utilizing ABA double extrusion technology, where ‘A’ represents the intermediate material and ‘B’ represents the outer layer material. By using different materials with varying extrusion melting temperatures and melt viscosities, combined with specific plasticizing conditions, the machine forms distinct middle and outer layers in the film, thereby enhancing its physical properties and durability.
Additionally, the production speed of the ABA film blower is faster than that of a single-layer machine, making it suitable for the mass production of film products. It also results in less uneven film thickness and better surface luster. However, for small-scale production scenarios, a single-layer machine is more economical and practical.
Do not stand directly in front of the machine during operation to avoid accidental injury.
Ensure no raw materials containing metal impurities or tools that could damage the machine enter the cylinder during feeding.
Avoid wearing gloves while operating rotating machinery to prevent injuries.
Regularly check and replenish lubricating oil in the reducer and air compressor.
Inspect the lubrication of all mechanical transmission parts to prevent damage, noise, or drying up.
Check for disconnected or leaking power wiring before startup.
Inspect instruments for damage or abnormalities.
Ensure all parts are safe and functioning properly to avoid production delays or accidents.
Within the film-forming range, increase the forming temperature, cooling air temperature, and swelling ratio to enhance film turbidity and gloss.
Once the mold outlet is uniform, wear gloves and slowly pull the tube.
Close the tube end and slightly open the air regulating valve to allow a small amount of compressed air through the core rod’s central hole.
Carefully guide the bubble through the steady bubble frame, font plate, and traction roller until it reaches the roll.
Set the compressed air pressure to an appropriate level to prevent tube breakage while ensuring the membrane tube remains symmetrical and stable.
This ensures consistent production quality.
Use the extruder and compressed air to clean the machine, but avoid damaging the screw or its smooth surface.
