Integrating infrared drying, airflow, and environmental control to shorten inter-layer shell mold drying time while maintaining quality stability.
Under applicable conditions, drying can be completed in as fast as approximately 6 hours, supporting 7-14 day rapid prototyping and sample delivery for precision castings.
The core of infrared fast drying technology is not only in reducing drying time, but more importantly in accelerating precision casting process development while maintaining shell mold quality and dimensional stability.
Through precise control of temperature, humidity, and airflow conditions, surface hardening, internal stress, and crack problems caused by rapid drying can be effectively avoided, ensuring shell mold structure and dimensional consistency.
The system can reduce drying time for multi-layer shell molds to approximately 6 hours, enabling engineering teams to quickly complete tree design, process parameter adjustments, and defect analysis, significantly reducing product development cycles and supporting 7-day rapid prototype sampling and delivery.

Shell mold drying quality and drying speed are mainly affected by four key factors: humidity, temperature, airflow speed, and slurry characteristics.
Traditional precision casting processes typically perform drying at approximately 24°C, 45–60% humidity, and low airflow conditions, with overall drying times typically requiring 50 hours to 6 days.
DS Technology has successfully reduced shell mold drying time to approximately 6 hours by optimizing temperature control, humidity management, airflow speed, and slurry formulations while maintaining stable shell mold quality and dimensional precision.
This technology has operated stably in mass production environments for over 15 years and has been successfully applied to multiple high-end precision casting products.
Additionally, we provide process optimization and technical consulting services to help customers establish stable and efficient shell molding and drying processes.
