High Speed Monolayer Vertical Rotary Film Blowing Machine: Buyer FAQs

The machine is configured for HDPE and LDPE film production. HDPE film thicknesses range from 0.008 to 0.08 mm, while LDPE film thicknesses range from 0.02 to 0.15 mm. Match the selected screw, die, and operating configuration to the film grade and thickness required for the order.

The film width range is 200 to 1,200 mm, depending on the model. Production output is 25 to 120 kg/h. Screw diameter options are Φ45, Φ50, and Φ55 mm, while die diameter options range from Φ60 to Φ250 mm. Send the target film width, thickness, material, and hourly output when requesting a machine configuration.

Material feeding uses an integrated force-feeding system, and extrusion rates can be adjusted with variable-frequency motors. Zoned heating controls manage the transition from solid material to molten material across the barrel. Vertical rotary traction supports stable film handling and neat winding, while automatic roll discharge reduces manual handling at the roll-change stage.

For installation planning, allow space for the extrusion, vertical traction, winding, and automatic discharge sections. Check the final layout against the selected machine model and the site's material-flow and roll-handling route.

The machine uses 38CrMoAlA nitrided steel screws. Gearbox models include 146#, 173#, and 180#. The die diameter is selected from Φ60 to Φ250 mm, and the heating system uses zoned heating coils. Record these details with the selected machine model so replacement discussions identify the correct screw, gearbox, die, or heating-zone component.

The rotary die uses a leak-proof design intended to prevent oil and granule leakage associated with traditional rotary die heads. Zoned heating controls support stable plasticization, and the automatic roll discharge system reduces manual handling. Maintenance planning should cover the die, screw, gearbox, heating zones, traction system, and winding section. Before ordering, send the selected model and intended film range to the supplier so the spare-parts plan matches the installed configuration.
