The Pathsfinder Film Casting Machine is best suited for casting Epoxy or Polyamide Resin Films of thickness as low as 80µ (0.08mm) and upwards with a tolerance of maximum 10-20µ and width up to 650mm. The machine is equipped with hot water circulation to keep the resin in flowable viscosity. The system offers temperature ranging from 60oC to 200oC depending on the temperature requirement of the resin mass. The heating media is water. The Machine is equipped with unwinding and winding stations and is servo driven.

Unwinding and Winding Stations

Machine is equipped with paper unwinders and winding station. Break can be applied to unwinders to keep the web tension for smooth film casting.

Winding station is Servo Driven with air-chucks for easy cantering and film winding. The winding drum with higher outer diameter ensures damage free film winding. The film winding can be done at a line speed as low as 1 m/min to any speed as per requirement and skill of the operators. We recommend a maximum winding speed of 8 m/min though, the machine can achieve much higher speed, if needed.

The winding station is equipped with dancer mechanism to ensure uniform web tension and to regulate servo speed depending on gradual increase of diameter of the wound film on the winding drum.

 

Film Casting & Sandwiching Machine

The Film Casting and Sandwiching Machine eliminates the requirement of prepreg (carbon or glass) thus giving the processor the advantage of instant usage of processed sandwich in to laminates. The carrier paper passes under a fabric (carbon or glass) fed from a top feed-roll and while passing through a set of calendaring roll, the resin is transferred to the fabric. The carrier paper is then wound back on to a take up roller fitted at the bottom. After the top fabric taken up the resin sheet, another fabric layer is fed from the bottom and is joined to the resin sheet, sandwiching the resin between the two layers. A top roll film is added at the second stage of the calendar to protect the sandwich at the final winding. The line is additionally equipped to cast the film sheet, thus providing the dual advantage for the composite processing. The film thus made can then be inducted in to two layers of fabric using the previous process.
