Single-layer CA Sheet Extrusion Line
A shoelace tip CA sheet extrusion line(Cellulose Acetate Sheet Extrusion Line) is a specialized production system used to manufacture cellulose acetate sheets, which are widely used in applications such as eyeglass frames, packaging, photographic films, and decorative laminates. Cellulose acetate is a biodegradable and eco-friendly thermoplastic derived from natural cellulose, making it a popular choice for sustainable products.
Key Components of a Cellulose Acetate film extrusion line
Resin Handling System:
Stores and feeds cellulose acetate (CA) resin pellets into the extruder.
May include drying systems to remove moisture from the resin, as CA is hygroscopic.
Hair comb sheet extrusion line's extruder:
The core component where CA resin is melted and homogenized.
Typically a single or twin-screw extruder with precise temperature control to ensure proper melting and flow of the material.
Die:
Shapes the molten CA into a flat sheet.
The die design determines the thickness and width of the final sheet.
Calendering or Polishing Rolls:
A series of heated and cooled rollers that calibrate the thickness, surface finish, and flatness of the extruded sheet.
These rolls also help gradually cool the sheet to prevent warping or defects.
Cooling System:
Cools the sheet to solidify it after extrusion.
May include air knives, water baths, or chill rolls, depending on production requirements.
Haul-Off Unit:
Pulls the sheet through the production line at a controlled speed to maintain consistency in thickness and dimensions.
Cutting and Stacking System:
Cuts the continuous sheet into desired lengths.
Stacks the sheets for packaging or further processing.
Control System:
A centralized control panel or PLC (Programmable Logic Controller) to monitor and adjust parameters such as temperature, speed, and pressure.
Spectacle frame CA sheet machine process overview
Material Preparation
Cellulose acetate (CA) resin pellets undergo drying and dehumidification before being fed into the extruder.
Extrusion
Resin is melted and homogenized in the extruder, then forced through a flat die to form a continuous sheet.
Calendering & Cooling
The sheet passes through calendering rolls to achieve precise thickness and surface finish.
A cooling system solidifies the sheet while maintaining dimensional stability.
Cutting & Stacking
The cooled sheet is cut to specified dimensions and stacked for packaging or downstream processing.
Advantages of shoelace tip CA sheet extrusion line
Eco-Friendly: Cellulose acetate is biodegradable and derived from renewable resources.
Versatility: Can be customized for various applications by adjusting additives, colors, and thicknesses.
High-Quality Finish: The produced sheets exhibit excellent transparency, gloss, and surface smoothness.
To meet specific customer requirements, our single-layer thin CA sheet extruder can manufacture single-layer to six-layer CA sheet products with thicknesses ranging from 1 to 6 millimeters.
