Fully Automatic Filter Cartridge End Cap Welding Machine (Smart)
This equipment is used for welding filter element end caps.
Equipped with a servo drive, it can weld end caps 10-20 inches in diameter.
Introduction
Features
As a smart automatic filter cap welding machine for mass production, this fully automatic servo model offers distinct advantages for filter factories seeking high output and low labor input:
✔ Full Servo-Driven System with Intelligent Parameter Tuning: The full servo drive system embeds a parameter self-tuning algorithm that automatically calculates most welding parameters, avoiding errors caused by manual debugging. This servo filter cartridge end cap welder ensures highly precise and consistent welding results batch by batch, stabilizing finished product quality and lowering reject rates.
✔ Intelligent Operation & Significant Labor Savings: Designed with user-friendly one-click start and one-click shutdown functions, plus a built-in fault self-inspection system that pops up warning prompts when abnormalities occur. This smart filter welder lets one single operator manage 2 to 4 units simultaneously, greatly reducing labor input and cutting overall production costs for filter manufacturers.
✔ Excellent Production Capacity & High Efficiency: Stable continuous operation enables an hourly output of 340 to 360 filter cartridges. High throughput meets the mass production demands of medium and large filter factories and shortens order delivery cycles.
✔ Wide & Customizable Welding Range: Standard applicable size is cartridge length 10 to 20 inches and diameter 68 to 80mm. Customized production is available for special non-standard lengths to satisfy diversified product layout requirements of different customers.
✔ Dual Optional Welding Heating Modes: This hot plate filter cap welding machine supports infrared non-contact heating and hot plate contact heating. The hot plate is treated with professional anti-adhesion coating to prevent material sticking, reduce cleaning frequency and guarantee clean and neat welding seams.
✔ Independent Intellectual Property Protection: Developed with proprietary technology, this equipment owns 2 invention patents and 2 computer software copyrights. Reliable technical strength provides long-term technical support for customers.
For a complete filter production line, pair this automatic filter cap welding machine with our filter cartridge cutting machine to prepare clean, burr-free cartridge ends and our filter cartridge extension machine to join cartridges into longer lengths.
