Sintered Stone Thermal Bending Furnace
sintered stone hot bending furnace is a specialized industrial kiln designed specifically for heating sintered stone slabs to approximately 1100–1250°C. At this temperature, the sintered stone softens and can be formed under high heat, allowing it to naturally conform to molds through gravity and material flow, enabling precise curved shaping.
Its core function is to transform rigid, brittle sintered stone panels into curved or three-dimensional components, such as arched feature walls, column cladding, curved island countertops, spiral staircase treads, cylindrical or square column wraps, curved corner transitions, and curved cabinet doors.
- Furnace body: Refractory insulation structure with high-temperature sealing for heat retention and stability.
- Heating system: Electric resistance heating elements with five-sided uniform heat distribution.
- Temperature control: Intelligent PLC control with touchscreen interface, allowing preset heating, holding, and annealing curves.
- Mold / kiln car: Supports stone slabs and molds; available in single or dual-station configurations.
- Cooling system: Air cooling or controlled slow-cooling channel for precise temperature regulation.
Sintered Stone Heat Bending Furnace Description
The sintered stone heat bending furnace is a specialized industrial solution designed for forming high-end sintered stone and rock slabs into complex curved and three-dimensional shapes. By precisely heating materials to their controlled softening range (up to approximately 1200°C depending on slab composition), the system enables controlled plastic deformation without compromising structural integrity. This makes it ideal for producing curved countertops, cylindrical cladding, column wraps, wave panels, and custom architectural surfaces widely used in residential interiors, commercial spaces, hotels, and luxury design projects.
Engineered for high efficiency and precision, the furnace features a multi-sided uniform heating system using high-performance HRE resistance heating elements to ensure consistent temperature distribution throughout the chamber. An advanced PID intelligent temperature control system, combined with high-accuracy thermocouples, maintains thermal stability within ±5°C. The system supports programmable multi-stage firing curves, including controlled heating, soaking, and annealing/cooling cycles, allowing operators to fine-tune bending results for different slab thicknesses (5–20 mm) and material compositions. A touchscreen interface with recipe storage, remote monitoring capability, automatic shutdown, and fault alarm functions ensures reliable and user-friendly operation.
To meet industrial production demands, the furnace is available in both single-chamber and dual-chamber configurations. The dual-chamber design significantly increases throughput by enabling simultaneous operations—while one chamber is heating and forming, the other can be loaded, unloaded, or prepared for the next cycle. This alternating workflow minimizes downtime and maximizes productivity. An integrated cooling system with directed airflow channels accelerates controlled cooling and improves dimensional stability after forming. With a finished product yield rate of up to 99%, this equipment provides a highly efficient and scalable solution for modern sintered stone fabrication and advanced surface design manufacturing.
