Custom Laboratory Plastic Film Extruder Machine PLC Controlled
Designed as a high-precision laboratory instrument, the casting machine facilitates the uninterrupted fabrication of homogeneous polymer films, serving both research purposes and small-batch production. Its workflow involves a series of stages, namely melt extrusion, die shaping, and controlled cooling. Compatible with a range of base polymers—including PE, PP, PET, and TPU—this device finds utility in experimental investigations, formulation refinement, and the verification of processing methodologies.
Uses expensive functional materials only for the thin outer layers, while the core uses a cost-effective polymer, significantly reducing costs.
The symmetrical structure produces a flat, stable film that resists curling and warping, ensuring good processability.
The dual supply allows for different materials on each outer layer (e.g., puncture-resistant on one side, heat-sealable on the other), enabling diverse functionalities.
Requires only two extruders to produce a three-layer film, lowering equipment investment and enhancing operational stability.
