Sintered Stone Hot-Bending Integrated Basin Kiln

The Sintered Stone Hot-Bending Integrated Basin Kiln is a specialized industrial furnace designed for the production of seamless integrated sintered stone sinks and countertops. It enables high-temperature softening and precision thermoforming of sintered stone slabs at up to 1280°C–1350°C, allowing the material to be hot-bent into curved basin structures and monolithic countertop-sink integrations.

Through controlled thermal deformation and mold shaping technology, the system eliminates the need for traditional 45° miter joints, adhesives, or seam bonding. The result is a fully integrated, joint-free surface, significantly improving structural integrity, durability, and long-term performance.

Compared with conventional fabrication methods, this hot-bending process eliminates grout lines and bonding interfaces, effectively reducing the risk of dirt accumulation, mold growth, discoloration, and long-term surface degradation. In addition to its functional advantages, it delivers a sleek, continuous aesthetic ideal for high-end residential bathrooms, luxury kitchens, and custom architectural stone applications.

Equipped with a multi-zone precision temperature control system, the kiln ensures uniform heating, stable bending performance, and controlled cooling—preventing cracking, deformation, or internal stress damage during forming. The result is high-strength, dimensionally stable finished products with excellent repeatability.

Available Models

1. Standard 6-Station Hot Bending Kiln

The standard model is designed for efficient medium-scale production of integrated basin products.

• Internal chamber size: 2800 × 1450 × 700 mm
• Capacity: 6 pieces (800–900 mm basins per cycle)
• Production cycle: ~7.5 hours per batch
  • Heating & forming: 3.5 hours
  • Insulation & cooling: 4 hours
• Daily output: up to 3 cycles / 18 basins per day (24-hour operation)
• Maximum temperature: 1350°C
• Heating method: electric resistance heating (heating elements)
• Control system: touchscreen PLC with segmented temperature programming
• Total power: 90 kW
• Energy consumption: approx. 240 kWh per cycle
• Average energy per basin: ~40 kWh
• Footprint: 5500 × 5000 × 2000 mm

This model offers a balanced solution between cost efficiency and production capacity, ideal for small-to-medium manufacturers.

The kiln is capable of simultaneously firing six sintered stone thermoformed integrated basins of different shapes and colors. It can also produce connected double basins formed in a single piece.

In one firing cycle, the kiln can accommodate either six basins sized 800–900 mm, or four basins sized 1000–1300 mm. It is also suitable for manufacturing customized thermoformed basins.

The system supports continuous 24-hour operation, achieving up to three firing cycles per day, with a maximum daily output of 18 basins.

2. Dual-Chamber 6-Station High-Efficiency Kiln

The dual-chamber model is engineered for high-output, continuous production with minimized downtime.

This system features a dual furnace chamber alternating workflow, allowing simultaneous loading and heating operations. While one chamber is in the heating/forming phase, the other is used for unloading and preparation. This alternating cycle significantly improves efficiency and reduces heat loss.

• Internal structure: dual independent 6-station chambers
• Capacity: 6 basins per chamber per cycle
• Daily output: up to 6 cycles / 36 basins per day
• Maximum temperature: 1350°C
• Heating method: electric resistance heating
• Control system: PLC intelligent segmented temperature control
• Total power: 120 kW
• Energy consumption: approx. 180 kWh per cycle
• Average energy per basin: ~30 kWh
• Footprint: 5500 × 6000 × 2000 mm

This model is optimized for high-volume manufacturing, offering improved energy efficiency, reduced cycle time, and higher throughput compared to single-chamber systems.

This kiln is capable of simultaneously firing sintered stone thermoformed integrated basins of different shapes and colors. In a single firing cycle, it can accommodate either six basins measuring 800–900 mm, or four basins measuring 1000–1300 mm. The system features a dual-chamber design, where heating/forming and heat preservation/cooling processes are carried out alternately. This significantly reduces processing time by approximately 50%. With continuous 24-hour operation, the kiln can complete up to six firing cycles per day, achieving a daily production capacity of up to 36 basins.

3. Compact 3-Station Hot Bending Kiln

The compact model is designed for customized production and smaller workshops requiring flexibility in design variation.

• Internal chamber size: 2700 × 700 × 600 mm
• Capacity: 3 basins per cycle (up to 800 mm size)
• Production cycle: ~7.5 hours
  • Heating & forming: 3.5 hours
  • Cooling: 4 hours
• Daily output: up to 9 basins per day
• Maximum temperature: 1350°C
• Heating method: electric resistance heating
• Control system: touchscreen PLC segmented temperature control
• Total power: 50 kW
• Energy consumption: approx. 150 kWh per cycle
• Average energy per basin: ~50 kWh
• Footprint: 3500 × 3300 × 2500 mm

This model is ideal for custom fabrication shops, boutique stone manufacturers, and multi-design production environments.

Capable of firing sintered stone thermoformed integrated basins of different shapes and colors simultaneously, as well as integrated double basins. One kiln load can accommodate either three 800 mm basins or two 1200 mm basins. With continuous 24-hour operation, the kiln can complete three firing cycles per day, achieving a daily output of up to nine basins.
