Single-Screw Co-Extrusion Casting Laminating Machine

Product Introduction 
Single-Screw Co-Extrusion Casting Laminating Machine consists of a precision single-screw extruder, filter, melt metering pump, dedicated die head, casting and laminating machine, gluing and drying device, unwinding and winding system, thickness gauge, defect detection system, and control system.
DESCRIPTION
Key Features
● Precise temperature control with an accuracy of ±1℃, featuring independent multi-zone temperature control to ensure uniform material plasticization and improved product stability. 
 
● Each extrusion main unit, casting roller and traction roller are independently driven by high-performance servo motors, enabling accurate speed control and convenient speed ratio adjustment between adjacent rollers, ensuring uniform film thickness and lamination strength.
 
● High customizability: die heads, screws and lamination processes can be customized in different specifications to meet exclusive application scenarios. 
III.III. Main Industries & Applications 
 
Industries: Plastics, rubber, chemical engineering, new materials, polymer materials, scientific research & education, electronics, new energy, packaging, medical, construction, etc. 
 
Applications: 
● Simulate actual production processes for polymer material co-extrusion, casting and lamination experiments, optimizing production parameters. 
 
● Produce functional composite films, such as food packaging films, medical films, photovoltaic adhesive films, geotextile composite films, etc. 
 
● Conduct material lamination performance tests to provide reliable process data support for subsequent large-scale production. 
 
● Compatible with various materials including biodegradable materials, EVA, PMMA, etc., to achieve multi-layer composite molding and meet diversified demands. Exclusive production process for PP raw materials: After drying, PP raw materials are melted and plasticized by the precision single-screw extruder, accurately measured via the filter and metering pump, extruded and cast into a film through the dedicated die head. After lamination, gluing and drying, the film undergoes online thickness measurement and defect detection before final winding. This process is suitable for the production of PP-based composite films, meeting the high-performance film requirements of packaging, electronics, construction and other fields.
