The “Helicord” and “Helilub” principle is based on friction between a fast-moving wire and a textile cord or yarn wound around a wire, strand or insulated cable multiple times, moving rather slowly under push-pull-controlled conditions, creating a multiple 360° contact between the constantly renewed cleaning cord and wire. Friction power on the wire increases linearly with the wire speed. This means the friction energy per wire surface unit and thus also efficiency is independent of the wire speed: “Helicord” can be run at drawing speeds.

The use of small amounts of liquids, such as water-based tensides, organic solvents, oil or a variety of dispersions, may be desirable or even required for both cleaning and coating processes, depending on the application in question.

For the welding wire industry, a variety of welding wire finishing cords is available, combining the superior properties of solid finishing materials with the high precision of “Helicord” coating. Other applications include, but are not limited to, cleaning insulated cable, applying primers or dispersions such as water- or solvent-based PTFE dispersions to bare wire or insulated cable, or even removing inkjet misprints from cable.

The most notable addition to the product range is a new setup allowing to apply the well-established fully circumferential looping principle even to the finest of wires which previously had to be treated using a multiple half-circumferential tangent process in order to prevent wire breaks. This opens up new opportunities in many areas, particularly in the medical industry, where numerous applications require wire to be both extremely small in diameter and very clean.

“Helicord” machines come in different shapes and sizes, suitable for anything from merely wiping off loosely adhering dust and metal particles, right up to a two-step process for abrasive grinding and finishing. Product diameters range from fine wire of about 20µm to cables of up to 18mm in diameter.

Exhibits at “wire 2026” will include various “Helicord” and “Helilub” machines and some “Labtech” equipment.

Established in 1982, Boockmann Engineering has over 40 years of experience bringing together utmost precision and environmental protection standards while providing customer-specific solutions that meet highest quality requirements. In the early years, their focus on outside-the-box problem-solving and unconditional ambition to see things through, working with customers until their requirements were fulfilled and their production lines ran reliably, provided for a reputation as one of the best suppliers to partner with in magnet wire surface treatment. Since then Boockmann Engineering has gathered invaluable knowledge in many fields and widened their scope of products and services to cater to a much larger part of the wire and cable industry with the same ambition and reliability. Focusing on delivering solutions rather than products and providing premium after-sales service and access to their wide knowledge base, they aim at 100% performance while keeping the “ecological footprint” as small as possible. This approach in combination with the high degree of in-house production depth allowing for an equally high degree of control over quality, and high quality German engineering make Boockmann Engineering your best choice in wire and cable surface treatment.
