1000L Two-Layer Blow Molding Machine
The 1000L two-layer blow molding machine represents an advanced evolution from single-layer systems, utilizing co-extrusion technology to produce containers with superior functional properties. This industrial equipment employs two separate extruders—each with 110mm screw diameters—that feed different materials into a collaborative die head, where they merge into a layered parison without complete mixing.
This configuration enables strategic material combinations, such as pairing a virgin outer layer with a recycled inner layer, achieving both premium surface quality and significant cost reduction. These systems maintain production capacities comparable to single-layer machines, typically achieving 16-25 containers per hour for 1000L products, while delivering substantially enhanced container performance.
The primary advantage lies in creating functional barriers against moisture, chemicals, and UV degradation, dramatically expanding application possibilities. The sophisticated control systems require precise synchronization between the two extrusion streams and incorporate advanced wall thickness control with up to 200 adjustment points for optimal material distribution.
