Retrofit and upgrades
Sustainable modernisation for performance, reliability, and lower CO₂ footprint.
Through targeted mechanical retrofits and automation upgrades, including control systems, software modules, and high-efficiency components, we improve system performance, extend asset life, and reduce energy consumption. Working closely with you, we implement solutions that reduce CO₂ emissions and align with your long-term efficiency and sustainability goals.

CONVEX™ mChute – Smart chute solution for safe maintenance
mChute is the CONVEX™ solution designed to make mixer maintenance safer, faster and more efficient: the automatically tiltable rear door, fully integrated into the safety chain logic, creates a stable anti-slip working platform that securely positions and locks the ladder, allowing safe access for up to two maintenance engineers. By providing a wider and safer access to upstream equipment, mChute significantly reduces hazards, minimises downtime and can be easily retrofitted on existing lines, turning maintenance operations into a controlled, reliable and productivity-oriented process
CONVEX™ Force Master – Intelligent load management for maximum performance
CONVEX™ Force Master is the state-of-the-art solution to upgrade the performance, reliability and availability of your CONVEX™ , replacing traditional breaking discs. Thanks to its high sensitivity to load variations and its highly accurate load measurement, Force Master provides continuous protection against load peaks, preventing mechanical stress and unplanned shutdowns. Fully integrated into the CONVEX™/TDE control system, it eliminates downtime related to disc replacement, reduces spare parts costs and increases overall machine availability, while remaining fully retrofittable on existing CONVEX™ and TDE installations
CONVEX™ Hydraulic Cushion Upgrade – Intelligent overload protection without downtime
The CONVEX™ Hydraulic Cushion Upgrade is an advanced alternative to traditional mechanical breaking disks, designed to protect the roller head from overloads caused by cold rubber or foreign objects while drastically reducing downtime and maintenance costs. By replacing mechanical breaking disks with a hydraulic cushioning system, the solution allows the machine to absorb excess roller head force and recover instantly, eliminating the need for component replacement, roller head movement or material discharge. Operators can simply reset the alarm and restart production, ensuring maximum line availability, zero wasted material and uninterrupted operation. As an additional advantage, the complete elimination of breaking disks removes all related handling, wear and reliability issues, delivering a cleaner, safer and more efficient overload protection concept. This upgrade is applicable only to the old full mechanical roller head.
CONVEX™ antisticking solutions
Automatic Transfer to Batch Off – Smooth, reliable and fully automated strip handling
The Automatic Transfer to Batch‑Off solution is designed to ensure a continuous, stable and safe transfer of the rubber strip from the CONVEX™ roller head to the batch‑off, combining advanced roll scrapers with an integrated conveyor belt. The scrapers are made of special anti‑sticking materials and optimized through extensive field experience, to prevent sticking, reduce unplanned shutdowns and improve machine availability, while ensuring easy and safe access for maintenance. The dedicated conveyor belt, fully integrated into the CONVEX™/TDE control system, synchronizes strip detection and speed regulation, protects the working area and ensures a smooth, automatic and controlled strip flow, significantly reducing manual intervention, improving process stability and minimizing downtime.
RAPID – Rolls Automatic Polishing Integrated Device
RAPID is a fully automatic and integrated solution designed for CONVEX™ and MILLMIX® machines to ensure consistently smooth and high‑performance roll surfaces. The polishing head moves safely along a rack fixed to the roll frame, allowing easy installation and fully controlled operation, with precise adjustment of key parameters such as abrasive film feed rate and motor speed. Using specially engineered abrasive films, RAPID eliminates surface irregularities in a uniform and repeatable way, significantly reducing rubber sticking – especially with high‑silica compounds – and improving overall line availability. Thanks to its flexible design, RAPID adapts to multiple roll coatings, while meeting the latest safety regulations and CE requirements for maximum operational reliability.
ROLLS TECHNOLOGY – Advanced cooling and surface treatment for superior line performance
ROLLS TECHNOLOGY combines HFG’s proprietary Super Cooling Technology with advanced roll surface treatments to maximize cooling efficiency, reduce rubber sticking and extend roll lifetime on CONVEX™ roller heads. The optimized cooling layouts, combined with dedicated anti‑sticking coatings, ensure stable processing conditions, improved corrosion resistance in demanding tyre applications and excellent resistance to wear and impact. Available in different configurations to match specific process requirements, ROLLS TECHNOLOGY enhances productivity, reduces cleaning and downtime, and delivers consistent, high‑performance operation over time.
