The main differences between a tunnel furnace and a batch furnace are structure, working principle, and application.
Structure
A tunnel furnace consists of a conveyor system, preheating section, high-temperature section, cooling section, and other parts. Its structure is relatively complex. A batch furnace uses a box-type structure. It mainly consists of a chamber, electric heaters, and a working space. Its structure is relatively simple.
Hansheng Automation can machine custom conveyor components, fixtures, and heat-resistant parts for tunnel furnaces from customer drawings, in single pieces or small batches.
Working principle
A tunnel furnace uses a conveyor system to feed workpieces into the furnace. It completes heating, holding, and cooling in sequence. Automation level is high. A batch furnace places workpieces into the working chamber for heating, holding, and cooling. Temperature and time control are more precise.
Applications
A tunnel furnace suits continuous heating on a production line. It offers high thermal efficiency and high automatic control accuracy. A batch furnace suits high-precision heat treatment of workpieces, such as quenching and annealing.
Beyond the parts discussed above, our precision component customization covers more than one industry. We machine filling machinery parts, medical device components, yacht precision components, RC car precision components, tobacco packaging machinery parts, food machinery parts, and printing machinery parts. Hansheng Automation works from customer drawings and delivers one-off or batch parts to the required material, tolerance, and surface finish. Our scope is precision components, not complete machines.
