  Recently, our company has completed a comprehensive technical optimization of the HEPA Mini Filter Full-Auto Non-Partition Pleating Production Line, achieving breakthrough improvements in four core areas: roller structure, gluing system, conveyor system, and overall machine design. The upgraded model delivers higher stability, precision, and operational convenience, providing reliable, high-performance solutions for HEPA filter manufacturers.   Four Core Technical Upgrades Dual Roller Structure Replaces Single Roller for Improved Pleating Flatness The new line adopts a dual-roller design instead of the traditional single-roller structure, ensuring smoother operation and more uniform stress distribution. Pleating is flatter and more consistent, with a fold height range of 10–120mm precisely adjustable via the touchscreen. Vertical Glue Nozzle for Smoother, More Uniform Glue Lines The glue nozzle is upgraded to a vertical gluing mode, enhancing glue application accuracy and stability. The improved system produces cleaner, flatter glue lines and stronger bonding for higher filter quality. Extended Conveyor Belt to 2.3 Meters for Larger Buffer Storage The conveyor belt is lengthened to 2.3 meters, significantly increasing buffer and storage capacity. This supports continuous high-speed production, reduces downtime, and improves overall line efficiency. Machine Frame Raised by 100mm for Easier Feeding & Better Appearance The main frame height is increased by 100mm, making paper feeding and positioning more convenient and ergonomic. The revised structure also improves the machine’s aesthetic and modern industrial appearance.   The upgraded Mini HEPA Filter Pleating Production Line integrates high precision, stability, and ease of use, ideal for automated manufacturing of high-efficiency air filters. Our company will continue to focus on technological innovation and product upgrading in filter equipment, striving to provide customers with more efficient, intelligent, and reliable production solutions to support the high-quality development of the global filtration industry.

A newly introduced Aluminum Foil Corrugating Machine is bringing improved efficiency and forming accuracy to the industrial production of aluminum foil and paper separators. Designed for stable, continuous operation, the 350mm corrugating system addresses the growing demand for consistent separator quality in filtration and related manufacturing sectors. As a specialized Paper Aluminum Filter Making Machine, the equipment integrates a fully automated workflow that covers material feeding, tension control, flanging, corrugation pressing, sizing, cutting, and automatic discharge. This streamlined process reduces manual handling and ensures uniform corrugation results, even during long production runs. By maintaining constant tension throughout the process, the machine helps prevent deformation of thin aluminum foil and paper materials. The system also functions effectively as a Separated Aluminium Foil paper Machine, featuring a magnetic powder brake and independent motor in the unwinding section. This configuration allows precise tension adjustment regardless of roll diameter changes, keeping materials straight and stable during forming. An adjustable inlet tension section further improves material control, reducing the risk of uneven corrugation or dimensional deviation. As 350mm Aluminum Foil Paper Corrugating Equipment, the machine offers flexible customization options to meet different production requirements. Corrugation height can be adjusted between 3 and 6 mm through replaceable roller sets, while sizing length remains freely adjustable. With a maximum output of up to 30 sheets per minute, the system balances productivity with forming precision. Pneumatic cutting knives with induction sizing ensure clean and accurate cutting of corrugated sheets. The equipment is also available as a fully automated 350mm Aluminum Foil Paper Auto Corrugator, combining forming, cutting, and discharge into a compact unit. Finished products are automatically discharged via a pneumatic platform, simplifying collection and stacking. Serving as a complete 350mm Aluminum Foil Paper Corrugating Forming Machine, the solution supports both aluminum foil and paper materials, making it suitable for manufacturers seeking reliable, scalable, and consistent separator production solutions.
