Fine Blanking’s Growing Impact on Key Sectors
In recent years, fine blanking technology has experienced significant growth across various industries, especially in the automotive, motorcycle, and precision electronics sectors. The automotive industry, in particular, accounts for roughly 50-60% of the total volume of fine blanking components. This advanced manufacturing technique, which evolved from traditional blanking methods, has gained popularity in the automotive sector due to its numerous advantages. These include reduced production costs, minimized energy consumption, improved quality and appearance of structural components, increased efficiency, and a focus on safety and environmental sustainability.

The Global Dominance of Swiss-based Feintool
Over 5,000 fine blanking machines operate worldwide, with Swiss-based Feintool producing more than 60% of the total. As a pioneer in the fine blanking industry, Feintool has played a significant role in promoting the widespread adoption of this technology. To cater to the Asian market, lower production costs, and champion fine blanking methodologies, Feintool launched the HFT series – a range of cost-effective, locally-manufactured fine blanking machines. The company has also partnered with local high-quality fine blanking production line equipment manufacturers to further reduce user investment costs.
Henli’s Breakthrough in Fine Blanking Production Lines
A major publicly-traded automotive parts manufacturer recently awarded a contract for a new 700T fine blanking production line project to Henli. This notable achievement saw Henli triumph over strong competitors from China, Taiwan, Japan, South Korea, and Europe. With a 20-year history of developing, designing, producing, and promoting early domestic stamping automation equipment, Henli has emerged as one of the first domestic suppliers of stamping automation equipment. Collaborating with renowned enterprises such as Magna, Haier, Bosch, Midea, Gree, Fuyao, and BYD, Henli’s forward-thinking and inventive team aims to create a comprehensive stamping equipment supply chain and propel China’s stamping automation industry to global leadership.
JC Series: Tailored Automation Solutions for Fine Blanking
Henli’s JC series of automated production lines, specifically designed for the fine blanking industry, are primarily compatible with Swiss Feintool, Heinrich, Schmid, Japanese Kawasaki and Mori Ironworks, and German SMG-Feintool fine blanking equipment brands. The production line’s primary functions include uncoiling, leveling (deburring), active transition table, feeding, lubricating, blanking, scrap cutting, part sorting (online monitoring), assembly, and transportation.
Key Features of the JC Series
- Loading trolley: Boasts hydraulic control for lifting, powered roller wheels for auxiliary feeding, automatic center positioning for material rolls, and automatic loading capabilities. Optionally, vision positioning and end-of-material detection functions are available for automatic material replacement or automatic removal of remaining material at specified locations.
- Heavy-duty uncoiler: Features precision multi-point positioning and limiting to maintain tight material rolls and stable material band curvature, with automatic scrap rewinding.
- Multi-group auxiliary feeding mechanisms: Rubber-coated roller wheels protect material surfaces while assisting the smooth entry of material head into leveling equipment.
- Precision leveling machine: Specially designed for high-strength plates and thick plates required for fine blanking component production, featuring a multi-row staggered roll frame structure, four-axis servo automatic micro-adjustment of leveling quantity, and meeting the fine blanking production requirements for 1-15mm thick materials. A typical 100mm length product can achieve a flatness of ±0.05mm. The innovative and stylish exterior design symbolizes the company’s rapid development.
- Transition table: Hydraulic control assists material entry into feeding equipment and provides guidance for both sides of the material strip.
- HFT7000 fine blanking machine: This machine incorporates the fine blanking process with extrusion, bending, and drawing forming processes, enabling the fine blanking press to work with multi-stage progressive fine blanking dies to directly manufacture intricate, high-precision workpieces. Generally, time-consuming and costly subsequent machining processes are not required. Even complex three-dimensional components can be produced through a single forming process by combining fine blanking and forming techniques. Typically, fine blanked parts can be directly assembled and used.
The Future of Fine Blanking Technology
The growing adoption of fine blanking technology in the automotive, motorcycle, and precision electronics industries highlights its potential to revolutionize manufacturing processes. Companies like Feintool and Henli continue to innovate and expand the capabilities of fine blanking machines, ensuring that they remain a cornerstone of advanced manufacturing techniques.
As technology advances and industries seek more efficient, cost-effective, and environmentally friendly manufacturing solutions, fine blanking is poised to play an even more significant role in shaping the future of production. By harnessing the benefits of fine blanking technology, companies can streamline their operations, reduce waste, and create higher-quality products, ultimately contributing to a more sustainable and efficient global manufacturing landscape.
