Yasui K2 NEXT 5 kW: Precision Vacuum Pressure Casting Excellence
The Yasui K2 NEXT 5 kW is a professional-grade vacuum pressure casting system engineered for jewelry production environments that demand absolute metallurgical perfection. Manufactured in Japan, this robust system provides a complete vacuum atmosphere to ensure flawless, oxide-free castings. By utilizing a 5 kW oscillation power source, the K2 NEXT 5 kW offers an ideal balance of energy efficiency and high-speed induction heating for medium-scale manufacturing.
Advanced Thermal & Metal Management
This system features a high-speed induction heating unit that provides extra mixing during the melt to ensure perfect segregation and a homogeneous gold alloy. To protect your investment, the K2 NEXT utilizes proprietary Variable Heat Control to minimize alloy evaporation and gold loss.
- Precision Temperature: The microprocessor-controlled P.I.D. auto-tuning system maintains temperature accuracy within +/- 2 degrees.
- Thermal Range: Capable of reaching temperatures up to 1200°C with the standard K-Type thermocouple, with optional configurations available for higher thermal requirements.
- Oxidation Protection: A specialized "OXY-Free" after-mode cooling system eliminates surface oxidation, keeping precious metals bright and reducing finishing time.
- Metal De-Gassing: Integrated de-gas cycles ensure the removal of trapped gases, resulting in compact, high-density castings with excellent mold filling.
Operational Throughput & Control
The 5 kW model is built for consistent, back-to-back casting cycles, featuring a highly efficient crucible volume designed to handle up to 600 g of 18 kt gold.
- Smart Memory: The E-Touch control panel stores 100 full-parameter programs in its memory, allowing for the immediate recall of optimal settings for different alloys.
- Airtight Sealing: A gas-cylinder elevation system secures the flask to ensure a tight gas seal during the 0.3 MPa pressure cycle.
- Consistent Flask Sizing: Accommodates standard 125 x 230 mm (5 x 9 in) flasks for a wide range of jewelry and small industrial components.
- Advanced Monitoring: Features a precise double-needle gauge with improved pressure sensing and accurate timing for consistent results.
Technical Footprint & System Stability
Designed for ease of maintenance and high process stability, the K2 NEXT 5 kW includes a self-diagnosis feature to monitor machine health and minimize downtime. The unit is engineered for reliable 3-phase power operation and utilizes a dedicated vacuum pump to maintain its professional casting atmosphere. With its space-saving industrial design, this system provides the precision and footprint necessary for modern, high-quality manufacturing environments.
Professional Support: All Yasui units are backed by Romanoff International’s technical remote training and after-sales support. For facilities operating on 220V, a dedicated Step Up Transformer (79-300-K3UPX) is available to ensure peak performance.
