Car Bottom Furnace Technology Reaches New Heights, Powering Smart and Precision Manufacturing in Heat Treatment

2025-11-28 09:37:06

With increasing demands on heat treatment quality across industries such as mechanical manufacturing, automotive parts, mold processing, and aerospace, Car Bottom Furnaces are undergoing a technical upgrade centered on high-precision control, structural optimization, and intelligent operation.

Structural Optimization for Enhanced Stability

The new generation of Car Bottom Furnaces features a modular furnace body combined with an integral welded and sealed structure, enhancing rigidity and sealing performance.
The car bottom section adopts a dual-rail drive system for smooth and reliable entry and exit, suitable for heavy-duty continuous operation.
The use of a compression-sealed furnace door minimizes heat loss and significantly improves temperature uniformity.

Intelligent Control for Easier Operation

Modern Car Bottom Furnaces commonly use a PLC + touchscreen system, enabling automatic temperature increase, soaking (holding), cooling, and alarm interlocks.
Some high-end equipment can be integrated into a Manufacturing Execution System (MES), allowing for the digital and informational management of the heat treatment workshop.

Wide Application Across Various Processes

Car Bottom Furnaces can be used for processes such as annealing, normalizing, quenching and tempering (Q&T), and stress relief for materials including carbon steel, alloy steel, cast steel, aluminum alloys, and copper alloys.

Industry Trend: Large-Scale and Intelligent Development

Currently, the Car Bottom Furnace is developing toward large-scale production, intelligence, and integrated solutions.

With their high-temperature precision control, automated operation, and reliable performance, Car Bottom Furnaces will continue to provide strong support for precision machining and high-quality production in the manufacturing industry.
