In modern wire drawing, lubrication is no longer a secondary consideration. It has become a central factor in determining process efficiency, product quality and operational consistency. As manufacturers push towards higher speeds, tighter tolerances and greater reliability, the demands placed on lubricant systems have evolved significantly. In an exclusive interview with Wire & Cable India, Mr. Devjit Ghosh, Sales Head-India, Lubrimetal India Pvt. Ltd., talks about how what was once treated as a consumable is now better understood as a performance-critical component of the drawing process. Lubrimetal has increasingly focused on this change, moving beyond product supply towards a more integrated understanding of how lubrication influences the entire drawing operation.
Wire & Cable India: Lubrication plays a crucial role in reducing friction and protecting the wire surface. How does lubricant selection influence drawing efficiency and product quality?
Devjit Ghosh: At its core, lubrication governs the interaction between wire and die. A correctly selected lubricant reduces friction, lowers drawing forces and limits heat generation— allowing for improved efficiency and higher line speeds.
More importantly, it forms a consistent protective film that prevents direct metal-to-metal contact. This is essential in avoiding surface defects such as scoring, die pickup, and micro-tearing, all of which can compromise downstream processing.
In practice, however, optimal performance rarely comes from a “standard” product. The most effective results are achieved when lubricant selection is closely aligned with the specific process—taking into account material grade, reduction per pass, die geometry and operating speed.
While lubrication is often the first variable to be adjusted when problems occur, it is rarely the root cause in isolation. More often, it is the interaction between die design, machine setup and material condition that determines whether a lubricant performs as intended.
This is where a clear distinction begins to emerge within the industry: between lubricants supplied as commodities, and those developed as part of a broader, process-focused approach.

WCI: Wire manufacturers use various lubricants, including dry soaps, wet lubricants, and synthetic formulations. How do these different systems serve different wire drawing applications?
DG: Wire drawing encompasses a wide range of materials and conditions, and lubrication systems must reflect this diversity.
Dry drawing lubricants, typically soap-based, continue to provide reliable performance in low- to medium-carbon steel applications. Their ability to form a durable solid film makes them particularly effective in multi-pass operations where load-carrying capacity is critical.
Wet drawing systems—whether oil-based or emulsion—are more suited to fine wire and non-ferrous materials such as copper and aluminium. Their cooling properties and cleanliness support high-speed operation and enhanced surface finish.
Synthetic lubricants are gaining ground across both sectors. Their appeal lies in consistency, controlled lubrication behaviour, and reduced residue formation. Increasingly, they are being specified not only for performance reasons, but also for their contribution to process stability and environmental compliance.
The most successful implementations are rarely defined by product type alone, but by how well the lubricant integrates with the overall process.
WCI: Proper lubrication can significantly influence die wear and wire surface quality. How do lubricant formulations contribute to improving these aspects?
DG: The relationship between lubrication, die wear and surface finish is both direct and measurable.
Modern lubricant formulations are designed to maintain a stable lubricating film under high pressure. This reduces frictional contact, limiting die wear and extending tool life. At the same time, it ensures a consistent interface, which is critical to maintaining surface integrity on the wire.
Where lubrication is inconsistent, the effects are immediately visible: increased die degradation, variable surface finish and more frequent maintenance interruptions.
Conversely, where lubrication is properly engineered and applied, manufacturers often see improvements not only in die life, but in overall process predictability.
One of the most significant developments in recent years has been a move away from viewing lubricants as standalone products. Instead, leading manufacturers are increasingly adopting an integrated approach—where lubricant formulation, application method and process conditions are considered together.
WCI: In high-speed drawing operations, process stability becomes critical. What role do lubricants play in preventing wire breakage and maintaining stable drawing conditions?
DG: As drawing speeds increase, the margin for error narrows. Small variations in lubrication performance can lead to significant fluctuations in friction and temperature.
In high-speed operations, lubricants must do more than reduce friction—they must actively stabilise the process. This includes maintaining a consistent coefficient of friction, dissipating heat effectively and ensuring uniform film formation throughout the drawing cycle.
Failure in any of these areas can result in wire breaks, surface defects and unplanned downtime.
In practice, it is often not a sudden failure that disrupts production, but gradual instability—minor variations in lubrication behaviour that, over time, translate into tension fluctuation, increased break frequency, and reduced confidence on the line.
For this reason, advanced lubricant systems are increasingly designed with stability as a primary objective. Resistance to thermal degradation, consistent coating behaviour and long operational life are no longer desirable features—they are essential.
WCI: Sustainability and environmental compliance are becoming increasingly important in manufacturing. How are lubricant technologies evolving to address these concerns?
DG: Environmental considerations are now firmly embedded in manufacturing decision-making. Lubricant technologies are evolving in response, not only to meet regulatory requirements, but to support more efficient and sustainable operations.
This evolution includes the reduction of hazardous components, improved biodegradability, and longer service life to reduce waste. Cleaner-running lubricants that minimise residue and simplify filtration are also becoming increasingly important.
At the same time, improved lubrication efficiency contributes directly to reduced energy consumption—highlighting the growing alignment between environmental responsibility and process performance.

WCI: What innovations in lubricant chemistry or application methods do you see shaping the future of wire drawing processes?
DG: One of the most significant developments in recent years has been a move away from viewing lubricants as standalone products. Instead, leading manufacturers are increasingly adopting an integrated approach—where lubricant formulation, application method and process conditions are considered together. This approach often involves closer technical collaboration, on-site evaluation and ongoing optimisation. In many cases, meaningful gains in productivity and quality are achieved not through major capital investment, but through incremental improvements in lubrication strategy.
In practice, this means working alongside production teams—not simply supplying a lubricant, but understanding how it behaves within the realities of the line, and adjusting it accordingly. This is the type of approach increasingly associated with Lubrimetal, where application knowledge is as important as formulation.
It is this level of engagement that differentiates suppliers who simply provide products from those who contribute to process performance and customers who optimize their process by collaboration with their suppliers and those who buy lubricants as a commodity.
The next phase of development in wire drawing lubrication will be defined by precision and control. Advances in synthetic chemistry and additive technology are enabling more predictable and stable lubrication behaviour. At the same time, improvements in monitoring and filtration systems are allowing manufacturers to manage lubricant performance in real time.
The direction is clear: towards lubrication systems that are not only effective, but measurable, controllable and increasingly tailored to individual production environments.
