1. Market Background

In major industrial hubs like Querétaro, Mexico, the investment casting industry is transitioning from high-energy-consumption legacy systems to automated, precision-controlled processes. As the critical first step in casting, dewaxing temperature consistency directly determines shell mold integrity. Traditional single-door furnaces, with low loading efficiency and significant heat loss, can no longer meet local demands for high-efficiency, green production.

2. Customer and Application Scenarios

The client is a Mexican precision foundry serving the aerospace and automotive sectors. Their operational requirements demand that the equipment maintain exceptional thermal field uniformity at a rated temperature of 900°C to prevent mold cracking. Furthermore, due to a flow-through production line layout, the client required a "front-loading, rear-unloading" heating solution with electrical components from international brands to ensure ease of local maintenance.

3. Our Solution: RX-100-10 Technical Analysis

To address the core needs of "stability, reliability, and maintainability," we provided the customized RX-100-10 Double-Door Box-Type Dewaxing Furnace:

• Double-Door Flow-Through Structure: Featuring vertical lifting front and rear doors equipped with a 1-ton electric hoist. The doors utilize a self-weight compression mechanism and full-fiber sealing, ensuring zero deformation and no heat leakage even at a peak temperature of 1000°C, significantly improving material turnover.

• 5-Side Heating Uniformity: Unlike standard furnaces, we distributed the heating elements (Shougang 0Cr21Al6Nb high-resistance alloy) across five sides (both side walls, bottom, back wall, and doors). This ensures that temperature uniformity within the 1000×1250×1100 mm workspace is better than ±10°C.

• Energy-Saving All-Fiber Lining: The lining utilizes high-purity aluminum silicate fiber from Shandong Luyang, with a total thickness of $ge$ 325mm. The compressed module design (density $ge$ 23.5 kg/m³) results in extremely low thermal conductivity, keeping the outer shell temperature rise $le$ 40°C, which greatly improves the workshop environment during Mexico's hot summers.

• Intelligent Control Architecture: The core system uses Shimaden (Japan) intelligent controllers combined with PID+SCR (Silicon Controlled Rectifier) power regulation, achieving a control accuracy of ±1°C.

5. Customer Feedback & Conclusion

After three months of operation, the Mexican client reported that the integration of the 10.1-inch HMI (Kunlun Tongtai) and Shimaden 485 communication allows their quality department to export historical temperature curves easily, perfectly meeting the traceability audit requirements for aerospace components. Additionally, thanks to the structural strength of the 30mm Ni7N steel bottom plate, no deformation has occurred during frequent loading/unloading. This solution provides high reliability and production consistency through parameterized performance.
