How can 3DRs Pressure Film help copper wire maker?

3DRs Pressure film (like Prescale®) is a tactile pressure-indicating sensor film that reveals pressure distribution and magnitude through a color change. For a copper wire maker, it is a powerful diagnostic tool for quality control and process optimization in several key areas:

· Lamination & Insulation: Ensures uniform pressure when laminating insulating films onto copper wires. Uneven pressure can cause wrinkles or allow etchant to attack the copper. Pressure film verifies nip pressure uniformity across rollers.

· Wire Drawing (Lubrication): In the drawing process, copper wire is pulled through a die to reduce its diameter. High pressure can squeeze the lubricating oil film, reducing its effectiveness and causing defects. Pressure film helps analyze pressure at the die interface to optimize lubrication.

· Electrical Connections: Copper wires develop insulating oxide films. Adequate pressure is needed to break these films for a low-resistance connection. Pressure film verifies that connectors and crimps apply sufficient, uniform pressure.

· General Quality Control: Used to verify the flatness of press plates and ensure uniform pressure in bolted connections, preventing loose connections or component damage.

In short, pressure film helps copper wire makers "see" pressure, allowing them to pinpoint issues like uneven roller pressure, insufficient connection force, or poor lubrication film integrity—leading to higher quality, fewer defects, and greater process reliability.
