Driven by increasingly stringent environmental regulations and the increasing demand for air and water purification solutions, the global filtration equipment industry is growing steadily. [According to GEP Research’s Global Environmental Protection Filter Equipment Industry Prospect Assessment Report in 2025-https://m.gepresearch.com/104/view-929483-1.html], the global market scale has exceeded 95 billion US dollars, and it is estimated that the compound annual growth rate from 2026 to 2030 is about 7.5%. In this booming market, the efficiency and precision of Pleating Machines have become crucial factors affecting the quality and competitiveness of filter equipment. Among various pleating solutions, the Pre-Slitting Marking Knife Pleating Machine stands out with its integrated design and advanced performance, providing strong support for the mass production of high-quality filter elements.
A Pre-Slitting Marking Knife Pleating Machine is a specialized integrated production line designed for filter equipment manufacturing. It is mainly composed of three core modules: pre-cutting machine, creasing machine and folding machine, which work together to complete the whole process from raw material processing to pleated filter element forming. Different from the single-function equipment, this integrated production line realizes the seamless connection of pre-cutting, marking and pleating, which greatly improves the production efficiency while ensuring the product quality consistency. It is specially developed for the production characteristics of filter elements, and the filter elements require high accuracy in pleat height, spacing and smoothness, which makes it an indispensable key equipment in the filter equipment manufacturing industry.
Compared with traditional Pleating Machines and separate production equipment, the Pre-Slitting Marking Knife Pleating Machine has four prominent advantages, which effectively solve the pain points of low efficiency, poor consistency, and complex operation in the traditional filter equipment production process.
Both the pre-cutting and folding modules of the production line are equipped with frequency converters, which can flexibly adjust the speed according to the specifications of different filter elements. Whether adjusting the paper feeding speed of the pre-cutting machine (0.5-12m/min) or the pleating speed of the folding machine (20-120 pleats/min), it can be done by simple operation. This not only simplifies the operation process, but also ensures the smoothness of the cutting and pleating results, avoids the waste of materials caused by speed mismatch, and improving the product qualification rate.
The creasing machine module can press straight-line or convex embossed creases according to production needs, and the crease spacing is precisely controlled by a computer system. This precise control ensures the consistency of each crease, thus making the filter element easier to shape in the subsequent assembly process. At the same time, the standardized creases also improve the aesthetic appearance of the filter element, enhancing the market competitiveness of the filter equipment.
The folding machine adopts an alternating mechanism of upper and lower blade to complete the folding action. This advanced mechanism can meet the pleating height requirements of 8-55 mm, and can process 1-5 layers of filter materials. The pleated filter elements is accurate in size and uniform in flatness, which effectively ensures the filtration area and efficiency of the filter element. For filtration equipment, especially for high-precision filtration products such as automobile filters and hydraulic oil filters, this high-precision pleating effect is very important to ensuring product performance.
The whole production line adopts a modular design, and each of the three core modules (pre-cutting, line pressing and folding) can run independently with an independent control switch. This design allows manufacturers to combine production processes flexibly according to their actual production needs. For example, when only pre-slitting or pleating processing is required, the corresponding module can be started separately, which improves the utilization rate of the equipment and reduces production costs. At the same time, the modular design is also convenient for equipment maintenance and repair, reducing downtime.
The Pre-Slitting Marking Knife Pleating Machine realizes the integrated production of filter elements through four consecutive steps, which are scientific and efficient, and easy to operate.
Raw Material Feeding: Put the roll filter material (with a thickness of 0.5-3 mm) into the pre-slitting machine. According to the preset width requirement (35-1100 mm), the pre-cutting machine adjusts the paper feeding speed through the frequency converter to ensure stable and uniform feeding of the material.
Pre-slitting processing: the pre-slitting machine cuts the rolled filter material into strips of the required width. The cutting process is smooth and accurate, which avoids the burrs and uneven edges of the material and lays a foundation for subsequent pleating processing.
Marking embossing: the cut filter material enters the marking machine, and the marking machine presses the required creases (straight lines or raised lines) on the material according to the production parameters. The crease height can be adjusted between 8 and 8-60 mm, and the spacing is controlled by a computer to ensure consistency. This step helps the filter material form regular folds during folding process.
Folding and forming: send the marked filter material to the folding machine. The folding machines use alternating upper and lower blade mechanism to fold the material into folds. Adjust the speed and height of pleating according to the product specifications, and finally form a pleated filter element with accurate size and consistent flatness.
