The benefits of repolishing dies by REDIES

REDIES, with its experience and expertise, offers a high-level repolishing service for natural diamond, PCD, and hard metal dies. In this article, we will explore the various stages of this process offered by REDIES and the resulting benefits.

Drawing dies are crucial components in the production of metal wires, tubes, and other products. Ensuring their optimal condition is essential to guarantee the end product quality.

The use of worn-out dies can lead to a range of problems, such as increased drawing force, loss of lubrication, wire ovalization, along with undesirable surface and dimensional defects in the finished product. Wear rings formation, damaged polishing, and presence of holes are the most visible signs that can be easily identified to recognize when a die has exhausted its useful life.

However, die replacement often entails a high cost for wire manufacturers. This is where REDIES' repolishing service comes into play.

Repolishing dies extends the tool's lifespan by restoring its usability. This way, the die regains its maximum precision and operational efficiency. Through this process, it's possible to maintain the original geometries and proportions, effectively obtaining a technically new die at a reasonable cost. From a performance perspective, the back relief also improves functionality.

Here are the main stages of the repolishing process:

- thorough die cleaning, removing any residues or contaminants that could affect the finished product quality;
- drawing ring removal using ultrasonics and geometric profile restoration (for tungsten carbide dies, high-speed grinding is employed);
- ultrasonic "mirror" polishing (for tungsten carbide dies, high-speed polishing is used);
- calibration according to customer-specific tolerances or REDIES' standard tolerances for new dies;
- final visual and diameter inspection;
- clear and permanent new dimension marking, allowing easy identification and traceability.
