Exploring the Inner Workings of Cast Film Machines

1. Basic Operation Steps

Material Loading

• Plastic pellets are added to the hopper for processing.

Extrusion Process

• The plastic pellets undergo plasticization and melting in a single-screw extruder.
• The molten plastic is then extruded from the main machine head.

Laminating and Forming

• The extruded material undergoes auxiliary lamination, edge trimming, flattening, and winding through the extrusion auxiliary machine.

2. Components of a Small Precision Cast Film Machine

2.1 Single Screw Extruder Module

• Main Motor
• Gear Reduction Gearbox
• Feeding Base
• Thrust Unit
• Screw
• Barrel
• Transition Section
• Die Head
• Heating/Cooling System
• Control PanelThe barrel and screw are crucial components, manufactured with high-performance materials, and the barrel surface undergoes nitriding treatment.

2.2 Extrusion Auxiliary Machine Module

Laminating Roller

• Each power roller is independently driven by a servo motor for precise control and good synchronization.
• The height of the laminating roller is adjustable to meet the processing requirements of different melt strength materials.
• The hard chrome-plated mirror surface roller with a 304 stainless steel core ensures high surface finish and corrosion resistance.
• Internal circulation water cooling system precisely controls the temperature of the laminating roller.

Traction Roller

• Comprises upper and lower rollers.
• The upper roller is driven by an independent motor with adjustable speed.
• The lower roller is coated with silicone for flexibility and can be moved up and down through a control cylinder.

Traction Roller Tensioning Mechanism

• Consists of buttons and cylinders, enabling the adjustment of the gap between the upper and lower rollers.

Winding System

• Driven by an independent torque motor with adjustable speed.
• Incorporates an internal pneumatic device to increase friction between the paper core and the roller for effective winding.
