Buss AG: Advanced Compounding Technologies Empower Indian Cable Manufacturers

In an exclusive interaction with Wire & Cable India, BUSS AG highlights that Indian producers are increasingly investing in advanced compounding technologies to achieve quality compounds, greater process stability, and compliance with stringent regulatory standards. BUSS, with its co-kneader technology, enables highly efficient distributive mixing, significantly reducing material degradation, scrap rates, and rework in demanding cable formulations, while supporting energy-efficient, future-ready manufacturing.

Wire & Cable India: Please briefly outline your company’s cable and wire industry product focus, including key technologies, product types, and principal end-use sectors.

BUSS: BUSS focuses on advanced compounding solutions for demanding wire and cable applications. Our core technology is the patented co-kneader, addressing heat and shear-sensitive formulations.

Our product portfolio covers co-kneaders for low, medium, high and extra-high-voltage insulation compounds, HFFR & silane crossed linked compounds for public infrastructure, semiconductive layers, filling and specialty compounds, and PVC pelletising.

Principal end-use sectors include energy transmission and distribution, building and infrastructure, transportation, and industrial cable applications, with growing emphasis on sustainable and recyclable materials.

WCI: Within your core product segments, how would you characterise current demand conditions and order visibility?

BUSS: Demand remains robust in segments linked to power infrastructure, renewable integration and urbanisation. Regulatory requirements for flame-retardant and low-smoke materials continue to support the demand for HFFR compounds. Order visibility is generally stronger for infrastructure-related projects, while some short-term volatility remains in more price-sensitive, commodity-driven segments.

WCI: Within your manufacturing offerings, how do you currently assess investment sentiment among wire and cable producers, particularly in emerging markets such as India?

BUSS: Investment sentiment in emerging markets such as India is clearly positive. Producers are increasingly investing in modern compounding technology to achieve higher quality, process stability and compliance with tightening regulations. In India, we see a strong interest in compact, energy-efficient and future-proof solutions that allow manufacturers to scale up quality without excessive complexity.

WCI: Which customer or application requirements are currently exerting the greatest pressure to improve productivity and quality within your product range?

BUSS: The key pressure points include optimized filler loadings in HFFR and semiconductive compounds, stricter electrical, mechanical and surface quality requirements, demand for reproducibility and process stability, and the need to process sensitive polymers and additives with minimal degradation. These requirements directly translate into a need for precise thermal control, gentle but effective mixing and robust process monitoring.

WCI: Which manufacturing disciplines, automation measures, or quality-assurance practices have delivered the most tangible improvements in your yield or rework reduction?

BUSS: The most tangible improvements have come from gentle compounding with controlled shear and temperature profiles, multi-point feeding strategies for fillers and additives, process customization based on rheological behaviour, and advanced monitoring of critical process parameters. In particular, BUSS co-kneader technology enables excellent distributive mixing, significantly reducing material degradation, scrap rates and rework in demanding cable formulations.

WCI: How are sustainability and decarbonisation goals translating into practical changes at your company?

BUSS: Sustainability is embedded in both our product design and process philosophy. We support the shift from cross-linked to thermoplastic and fully recyclable cable materials, enabling circular-economy concepts.

Our machines are designed for exceptionally long service life, with many installations operating for decades and continuously modernised. Compact plant layouts, optimized energy consumption, reduced material waste and simplified cleaning all contribute to lower environmental impact and reduced CO₂ footprint.

WCI: How are cost pressures across raw materials, energy, or logistics being managed without compromising product reliability or compliance?

BUSS: Cost pressures across raw materials, energy and logistics are primarily addressed through process efficiency and material optimisation rather than through compromises in quality or compliance.

A key lever is the efficient use of raw materials, enabled by precise compounding and highly effective distributive mixing, which helps minimise material waste, scrap and rework. Energy consumption is reduced through compact plant designs, optimised thermal management and stable, repeatable processes that avoid unnecessary start-up losses or off-spec production.

In addition, robust and reproducible process technology supports consistent product quality even when formulations or supply conditions vary. This allows manufacturers to maintain compliance with increasingly stringent technical and regulatory requirements while operating under challenging cost conditions.

WCI: How has the wire and cable industry benefited, in practical terms, from automation or real-time digital control?

BUSS: Automation and real-time digital control have significantly improved process stability, traceability and reproducibility. Digitally enabled machine monitoring supports predictive maintenance, higher uptime and consistent product quality.

For cable compounds with narrow processing windows, real-time control is essential to ensure compliance with electrical and mechanical specifications.

With BUSS SenseHUB, these capabilities are taken even further. The platform consolidates live process, quality and maintenance data in one digital ecosystem, enabling operators to react immediately to deviations. In addition, SenseHUB provides meaningful analytics and dashboards that help continuously optimize performance and energy efficiency across multiple production lines.
