The core challenge in the can manufacturing industry lies in the varying demands across different can types—such as food cans, chemical drums, and aerosol cans—regarding welding precision, material compatibility, and production efficiency. Addressing this challenge, Changtai Intelligent's R&D team has undergone years of technological iteration to introduce the FH18 series of fully automatic variable-frequency seam welding machines for can bodies. Leveraging three key technological advantages, these machines overcome industry pain points:
1.Diameter Adaptability
This series of equipment precisely accommodates materials ranging from 0.2 to 1.2 mm in thickness, including tinplate and coated steel. It supports can diameters from 38 mm to 90 mm, with adjustable can heights ranging from 50mm to 600mm. This versatility enables precise welding for small aerosol cans and food containers while also handling thick-material welding for large containers like 20L-60L lubricant drums and fertilizer barrels. This overcomes the limitation of traditional equipment being “one machine for one purpose.”
2. Intelligent Temperature Control and Weld Seam Protection Technology
The equipment features a high-frequency electromagnetic induction heating system integrated with a front-end compressed air cooling unit, enabling real-time control of weld seam temperature to prevent powder caking and adhesive bubbling caused by excessive heat. Simultaneously, the seam welding overlap can be precisely adjusted between 0.8-1.5mm, with weld point spacing maintained within ±0.1mm tolerance. This ensures optimal weld seam sealing integrity and surface flatness, meeting stringent standards for food-grade and chemical-grade containers.
3. Enhancing Collaborative Efficiency Across the Entire Production Line
This series of equipment seamlessly integrates with the company's independently developed can body interior/exterior touch-up coating machine, high-frequency electromagnetic drying machine, and powder coating machine, forming a fully automated “welding - coating - drying” production line. Taking food can production as an example, the entire line achieves a production speed of 60-120 cans per minute—over three times more efficient than traditional semi-automated lines. Its PLC control system enables one-click parameter switching, reducing changeover time to under 15 minutes and significantly minimizing downtime.
Notably, this equipment series holds a national utility model patent (Patent No.: 202220968273.5). Core components utilize internationally renowned brands like Siemens and Schneider Electric. Coupled with a one-year full-machine warranty and 24-hour after-sales response, it ensures long-term stable operation.
