Frequently Asked Questions (FAQ)
It is used for efficient processing, heating, drying or material transformation.
Solid and off-the-road tyres are thick, dense rubber masses where conventional convection ovens struggle to deliver uniform heat through the full cross-section within a reasonable time, often leaving the core significantly cooler than the surface when the tyre reaches the press. Microwave energy penetrates the rubber volumetrically, heating from the inside as well as the outside simultaneously, which produces a far more uniform temperature profile through thick tyre sections before vulcanization begins. This uniformity translates directly into more consistent cross-link density throughout the tyre during pressing, reducing the internal cure variation that contributes to premature failure, uneven wear, or delamination in solid tyre applications subjected to heavy industrial loads.
High efficiency, process reliability and complete customization.
Food, chemical, pharma, biomass, rubber, textile and more.
Kerone ensures high product quality through strict engineering standards, advanced testing procedures, and precision-controlled manufacturing systems.
Rotating turntable mechanisms continuously reposition the tyre relative to the microwave field, combined with optimized cavity design, ensures uniform temperature distribution throughout the rubber mass.
The preheated tyre is immediately transferred to the vulcanization press while temperature is maintained, ensuring optimal vulcanization conditions with reduced press cycle time.
Yes, all Kerone microwave systems comply with international microwave safety standards, with interlocked access panels, leakage detection, and automatic shutdown on fault conditions.
Once a tyre reaches target preheat temperature, it is transferred immediately to the vulcanization press while temperature is actively maintained, ensuring the rubber enters the press at optimal condition for curing rather than cooling during transfer and losing the benefit of preheating. This requires tight coordination between the preheater's cycle completion and press availability, often managed through PLC-based scheduling that signals press readiness before the preheat cycle finishes. Minimizing the physical distance and transfer time between preheater and press, along with insulated transfer mechanisms where transfer time is unavoidable, helps preserve the temperature uniformity achieved during preheating so the press cycle benefits fully from the reduced ramp-up time.
Scrap and rework in solid tyre production frequently trace back to uneven vulcanization caused by temperature gradients within the rubber mass at the start of the press cycle. When a tyre enters the press with cooler internal sections, those areas cure more slowly and can end up undercured relative to the surface, creating internal weaknesses that may not be visible until the tyre is in service and fails prematurely under load. By delivering a uniform starting temperature throughout the tyre's cross-section, microwave preheating reduces this gradient-driven cure inconsistency, which directly lowers the rate of tyres rejected during quality inspection or returned due to in-service failure. Manufacturers typically track this improvement through reduced scrap percentage and warranty claim rates after switching from conventional to microwave preheating.
Cycle time depends heavily on tyre mass, cross-sectional thickness, and target preheat temperature, but microwave preheating consistently achieves shorter cycle times than convection ovens for equivalent thick-section tyres because energy is delivered directly into the rubber mass rather than relying on slow conduction from a heated air environment. Convection ovens preheating large OTR tyres can require extended dwell times measured in hours to achieve adequate core temperature, while microwave systems typically reduce this substantially due to volumetric heating. Exact cycle time figures should be established through supplier trials using the specific tyre size and compound in question, since published general figures can vary widely based on tyre geometry and target temperature.
The evaluation should start with quantifying current scrap rates, press cycle times, and energy costs associated with existing preheating methods, then comparing these against the typical improvements microwave preheating delivers, including reduced press cycle time, improved temperature uniformity, and lower energy consumption per tyre processed. Facilities running high volumes of thick-section solid or OTR tyres, where temperature gradient problems are most pronounced, typically see the fastest return on investment. Smaller operations or those producing thinner-walled tyres where conventional preheating already performs adequately may see a longer payback period. Requesting a trial run with the manufacturer's actual tyre sizes and compounds provides the most reliable basis for this investment decision rather than relying on generic industry figures.
Capacity can be scaled by adding parallel preheating units to handle increased throughput, by specifying a larger cavity and higher-power generator configuration from the outset to accommodate anticipated growth, or by upgrading conveyor and turntable mechanisms to increase cycle frequency. Manufacturers expecting volume growth within a few years of initial installation should discuss modular expansion options with their supplier during the specification phase, including electrical infrastructure capacity for additional generators, since retrofitting power capacity after installation is typically more expensive and disruptive than planning for it during the initial facility design and electrical layout.
