HF’s Curemaster represents a significant shift in tyre curing technology, aligning with the industry’s move towards sustainability and efficiency. As the tyre market evolves, major manufacturers are prioritising premium segments, creating demand for advanced curing solutions. HF’s electric curing technology offers greater precision, efficiency and flexibility, particularly for high-end tyres. With digitalisation, predictive maintenance and automation, Curemaster addresses key industry challenges while maintaining cost competitiveness.

Curing presses are essential in tyre manufacturing as they shape and vulcanise raw rubber into a durable, high-performance tyre. Advanced curing presses enhance efficiency, reduce defects and support evolving tyre technologies. While most curing presses use steam as its power source, the trend is now shifting towards electric.

HF’s Curemaster is one such solution that leverages electric heating for enhance curing efficiency. While the company had already rolled out the Curemaster for truck and bus tyres, the passenger tyre variant was under development.

Speaking to Tyre Trends recently, HF Group Executive Vice President Warren Rudman noted that the Curemaster for passenger car tyres is now fully developed and available for sale. It comes in two versions including electric and the conventional steam press. Additionally, there is a hybrid option that combines both steam and electric curing for greater flexibility.

Alluding to market opportunities for Curemaster, Rudman informed, “The Indian market presents a huge growth opportunity and is a key focus for us. However, we also see strong potential in premium tyre manufacturing segments in other regions. The new Curemaster, with its electric heating, offers unique benefits, particularly in terms of quality and efficiency.”

The company is positioning the new Curemaster at the same price as conventional steam presses, aligning with its long-term strategy to drive adoption without cost barriers. “Customer response has been overwhelmingly positive, with a strong order intake already secured. The first units will be delivered for installation in August across South America, Europe and Asia, marking a global launch after one year of development,” said Rudman.

The Curemaster builds on insights from HF’s earlier truck and bus tyre (TBR) version. “Lessons from the TBR model led to significant value engineering, reducing production costs and enhancing design efficiency. These refinements have been integrated into the new Curemaster, ensuring it meets customer expectations on both performance and pricing,” revealed the executive.

PEEKING INTO SPECS

The Curemaster lineup now includes 14-to-24-inch models for passenger car tyres, alongside 60-inch versions for truck and bus tyres, making it suitable for both mass production and premium segments. Its flexibility allows manufacturers to produce a full range of tyres efficiently, regardless of volume or segment.

Commenting on customer demands, Rudman informed, “Customers are increasingly prioritising sustainability, driving the demand for eco-friendly curing processes that reduce energy consumption and carbon emissions. At the same time, cost efficiency remains a critical factor with growing pressure to balance affordability and high performance. Manufacturers must innovate to deliver solutions that optimise costs without compromising quality. Additionally, operational efficiency is a key focus as customers seek advanced technologies that enhance energy savings and streamline processes. The push for greater productivity through automation, predictive maintenance and data-driven insights is shaping the industry’s future, making efficiency-driven innovations essential for staying competitive.”

The order book for Curemaster is strong with a surge in orders during the first two months of the year. The executive anticipates continued momentum throughout the year, driven by increasing global demand for advanced, sustainable curing solutions.

FORWARD INTEGRATION

According to Rudman, digitalisation is playing a crucial role in enhancing the efficiency and reliability of curing presses. “Digitalisation provides real-time visibility into production processes, allowing manufacturers to monitor efficiency and product quality continuously. With a clear overview of operations, manufacturers can identify inefficiencies and ensure production targets are met. The HF XPLORE digital portal offers access to critical data at all times. It provides insights into machine health, predictive maintenance alerts and production performance. The system helps track efficiency, detect potential failures and optimise operations by identifying areas for improvement,” he said.

Artificial intelligence is also slated to play a key role in electrical heating, ensuring stable temperature control within the platens. Machine learning is being developed for predictive maintenance, helping to forecast bladder life and detect potential failures before they occur. These technologies are part of the company’s development roadmap, focusing on improving reliability and efficiency in curing press operations.

He also noted that as tyre compounds evolve, curing requirements will change, making electrical curing a more suitable solution. Unlike steam-based systems, where temperature is directly linked to pressure, electrical curing allows independent control of both factors. This flexibility is crucial for processing new materials that may not tolerate traditional curing conditions.

“In steam curing, the relationship between pressure and temperature is fixed. For example, achieving a temperature of 200 degrees Celsius requires increasing the pressure to 20 bar. With electrical curing, temperature and pressure are completely separate, enabling curing at lower temperatures while maintaining the necessary pressure levels. This capability is particularly significant for future materials, which may require curing at 160 degrees Celsius but at much higher pressures,” explained Rudman.

The shift towards electrical curing is expected to gain momentum, particularly for high-end and specialised tyres that demand more advanced curing strategies. While steam curing will continue to be used for lower-segment applications, the upper range of the market, especially where sustainability and material innovations are key factors, will require the precision and adaptability that electrical curing provides.

OVERLAPPING TECHNOLOGIES

There is a clear trend in the market where customers are seeking more customised solutions rather than standard off-the-shelf curing presses. Manufacturers now have unique requirements including features like electrical curing, digitalisation, automated loading and unloading and seamless integration with factory infrastructure and tyre transportation systems. As a result, the demand for tailored solutions is increasing, making flexibility a key factor in the adoption of new curing technologies.

“Curemaster is designed with upgradeability in mind, ensuring that tyre manufacturers do not have to replace entire presses when looking to modernise operations. Even older HF curing presses that have been in service for more than 20 years can be upgraded to electrical curing without altering the mechanical structure. This allows manufacturers to transition to more efficient curing technology while retaining the existing equipment. At the same time, the new Curemaster is available as a fully electric system from the outset, offering a ready-made solution for greenfield projects,” averred Rudman.

Nonetheless, the biggest business potential currently lies in retrofitting existing curing presses rather than selling entirely new equipment. “Many customers prefer upgrade kits that allow them to transition to electrical curing while maintaining current production setup. While greenfield projects present a significant opportunity for new fully electric presses, the greater demand at present is for retrofit solutions, as it provides a cost-effective way to improve efficiency and sustainability without major infrastructure changes,” he added.

PROCESS OVERVIEW

Most curing press suppliers have introduced electrical curing solutions. There are two main approaches to electrical heating, which are electromagnetic (induction) heating and resistive heating.

Electromagnetic heating method involves placing a coil outside the tyre to generate heat. However, there are concerns about how this method interacts with the tyre’s internal bead wire and breaker package. Since the long-term impact of electromagnetic fields on tyre integrity has not been fully tested or verified, there are still some uncertainties regarding its effects on tyre quality.

In contrast, resistive heating, which the company employs, places coils directly inside the plate, ensuring controlled and targeted heating. This method eliminates any risk associated with electromagnetic interference and allows precise temperature application only where needed. While both technologies are viable, resistive heating offers greater reliability and consistency in maintaining tyre quality.

“One of the key advantages of electrical curing is its rapid heating and cooling capabilities. The nitrogen used in the process can be heated from 20 degrees Celsius to 250 degrees Celsius in less than 20 seconds and cooled back down in the same time frame. This is achieved through continuous nitrogen circulation, where the system directs the flow through either the heater or the cooler as needed. In terms of curing time, electrical heating currently matches steam curing with a typical cycle of 10 minutes per tyre. However, there is significant potential to reduce curing time by 10 to 15 percent as electrical systems can operate at higher temperatures and offer more precise control over the process,” informed Rudman.

Nonetheless, steam curing has a predominant risk of mishaps in the bladder, which could lead to an explosion. The Curemaster is designed with a fully encapsulated dome, ensuring that any pressure build-up remains contained. If a failure occurs, the pressure is released downward instead of sideways, reducing the risk of injury.

The locking system is also unique. Even if there is a total power or hydraulic pressure loss, the press cannot open unintentionally. This containment and locking mechanism ensure a high level of safety during operation.

CHALLENGES AND OPPORTUNITIES

According to the executive, the biggest challenge in the curing press business comes from cost competition as lower-cost manufacturers pose a significant pricing challenge. However, from a technological standpoint, the company offers unique features that set it apart from competitors. While competitors may have cost advantages, HF’s focus on advanced technology, automation and digitalisation allows it to capture market share by offering superior functionality and efficiency.

The passenger car and truck segments remain the company’s primary focus owing to the highest growth potential. Additionally, the company sees an emerging opportunity in motorcycle and bicycle tyre curing, particularly with electric heating technology. HF is among the first to introduce electrical curing for these segments, positioning itself as an industry leader.

While HF is active in the passenger and truck segments, it has opted not to enter the off-the-road tyre market due to its relatively small size and intense competition. The segment still relies heavily on traditional mechanical presses, making it less attractive for innovation-driven solutions.

The company continues to refine the Curemaster lineup by introducing new materials, insulation techniques and design concepts. The company is particularly focused on increasing automation to enhance efficiency and reduce operational costs.
