Hot box core making machine
- Faster Production than CO₂/Silicate: Significantly faster curing (seconds/minutes vs. minutes/hours for drying-based processes) enables higher throughput compared to CO₂ or air-set processes.
- Good Core Strength & Hardness: Produces cores with substantially higher green strength than CO₂ silicate cores, reducing breakage during handling and molding. Suitable for cores needing moderate structural integrity.
- Good Surface Finish: Generally produces better casting surface finishes than CO₂ silicate cores.

Applications
A Hot Box Core Making Machine is an automated foundry machine designed to produce sand cores by thermally curing a sand-resin mixture inside a heated core box. It’s a core production method falling between the simpler CO₂/silicate process and the more advanced (but faster/cooler) Cold Box process in terms of complexity, speed, and performance.
Hot Box machines are suited for medium-to-high volume production of cores requiring good strength, reasonable detail, and faster production than CO₂, but where the investment or complexity of Cold Box isn’t justified. Common applications include:
- Automotive: Brake drums, suspension components, simpler engine parts (like oil pans, covers), differential carriers, pump housings.
- Industrial Valves & Fittings: Valve bodies, pipe fittings, flanges.
- General Machinery: Gear blanks, housings, brackets, pulleys.
- Agricultural Equipment: Transmission cases, housing components.
- HVAC: Compressor housings.
- Electric Motors: End shields, frames.
Main Benefits
- Faster Production than CO₂/Silicate: Significantly faster curing (seconds/minutes vs. minutes/hours for drying-based processes) enables higher throughput compared to CO₂ or air-set processes.
- Good Core Strength & Hardness: Produces cores with substantially higher green strength than CO₂ silicate cores, reducing breakage during handling and molding. Suitable for cores needing moderate structural integrity.
- Good Surface Finish: Generally produces better casting surface finishes than CO₂ silicate cores.
- Good Dimensional Accuracy: Capable of producing reasonably complex cores with adequate dimensional accuracy for many applications.
- Improved Shakeout vs. CO₂: While not as easy-shake as modern Cold Box binders, Hot Box cores generally collapse better than hardened CO₂ silicate cores after casting.
- Lower Initial Investment than Cold Box: Equipment (machine and core boxes) is generally less expensive than equivalent Cold Box systems, as it doesn’t require complex gas handling, scrubbing, or sealed systems.
- Simpler Chemistry than Cold Box: Uses liquid resins only (no separate gas catalyst system required). Easier binder supply logistics.
- Lower Binder Cost than Cold Box: UF/PF resins are generally less expensive per unit than the two-part binders plus amine gases used in Cold Box.
- Established Technology: Well-understood process with readily available materials and expertise.
- Energy Efficient Heating: Modern machines use efficient electric cartridge heaters or thermal oil systems within the core boxes, minimizing wasted heat.
