Regenerate, don’t replace: how to cut wire drawing costs with capstan revamping

In wire drawing operations, machine downtime is expensive. A worn-out capstan isn’t just a piece to replace: it leads to scrap, frequent maintenance, and overall inefficiency. But replacing it with a new one isn’t always necessary. Many companies are now choosing to regenerate their capstans instead, adopting solutions that reduce costs, cut CO₂ emissions, and extend the service life of components. It’s a win-win situation, good for the planet, and easy on your wallet.

So, how does capstan revamping work and when is it the right move?
We discussed this with RTP Paganoni, a company with over 40 years of experience in the supply of Z1000 sintered ceramic parts, proprietary wire drawing coatings like Diamond 3000, and HDC black ceramics.

Capstan revamping: why partner with RTP Paganoni

Revamping a capstan is not just a basic repair, it’s a structured technical process engineered to ensure reliable performance. Regenerating a worn-out capstan means restoring it to optimal working condition and extending its lifecycle without compromising functionality.

RTP Paganoni’s technical team follows a precise method, including:

• - analysis of operational parameters (material, drawing speed, service conditions)
• - removal of the worn coating
• - sandblasting and surface preparation
• - application of a new coating fitting to the specific wire type
• - precision grinding and lapping
• - dimensional and functional testing with a FARO 3D measuring arm

At the end of the process, the capstan is returned to the line “as good as new,” delivering peak performance with a smaller environmental impact.

RTP Paganoni also coordinates every step to minimize downtime. With careful logistics planning, the revamping process fits smoothly into the customer's production schedule. Want to extend the life of your capstans? Contact RTP Paganoni’s technical department using the information on this page.
