For sheet metal fabricators seeking flawless flattening and hemming results, Fierte’s spring loaded helping dies—also known as press brake hemming dies with spring for flatten—are the ultimate solution. These specialized sheet metal hemming tools integrate a innovative spring-assisted mechanism that delivers consistent pressure, ensuring smooth, wrinkle-free flattening of sheet metal edges and seams. Designed for use with a wide range of press brakes, our spring-assisted flattening dies are crafted from premium 42CrMo4, 42CrMo, and C45 alloy steels, undergoing rigorous heat treatment and precision engineering to meet the demands of high-volume production and precision-focused projects. Whether you’re working on automotive components, HVAC systems, or consumer electronics enclosures, these press brake hemming dies combine durability, efficiency, and ease of use to elevate your sheet metal processing capabilities. Fierte’s commitment to cutting-edge technology and quality craftsmanship ensures that every spring loaded helping die delivers reliable performance, reducing rework and boosting productivity.
The core of our spring loaded helping dies is a high-performance spring mechanism that provides uniform, adjustable pressure during the flattening and hemming process. This design eliminates uneven force distribution, a common cause of wrinkles, warping, or incomplete flattening in sheet metal workpieces. The spring’s flexibility adapts to varying material thicknesses, ensuring consistent results across different projects—from thin gauge sheets to thicker plates.
Like all Fierte press brake dies, our spring loaded helping dies are manufactured from 42CrMo4, 42CrMo, and C45 high-quality alloy steels. These materials are selected for their exceptional strength, impact resistance, and wear resistance, ensuring the dies withstand the repeated stress of hemming and flattening operations. The robust construction minimizes tool deformation, extending service life and reducing maintenance costs.
To enhance hardness and durability, each press brake hemming die undergoes whole body heat treatment, achieving a Rockwell hardness of HRC48-50. This process ensures that the die’s working surface remains sharp and resilient, even after thousands of cycles. The uniform hardness also prevents chipping or cracking, a critical advantage for tools used in high-pressure press brake applications.
We offer three surface treatment choices to optimize performance in different environments: blackening, sandblasting, and sandblasting + blackening. Blackening provides a protective layer against corrosion, sandblasting reduces friction for smoother workpiece release, and the combined treatment offers maximum durability and functionality. Each treatment is applied with precision to ensure long-lasting performance in industrial settings.
Our spring assisted flattening dies feature meticulously calibrated dimensions—including 13mm, 23mm, 15mm, 10R, 12R, 20.285mm, 21.233mm, and 20.304mm—to ensure a perfect fit with most press brake models. The precise tolerances guarantee alignment accuracy, which is essential for achieving consistent hemming and flattening results. Every die is inspected for dimensional accuracy before leaving our facility.
These sheet metal hemming tools are compatible with leading press brake brands and types, such as Amada/Promecam, Trumpf/Wila, Bystronic/Beyeler, LVD type, American standard type, and Gasparini type. This versatility makes them a valuable addition to any workshop, eliminating the need for multiple specialized dies for different machines.
The spring-loaded mechanism simplifies operation by automating pressure adjustment, reducing operator effort and minimizing human error. The dies’ smooth working surface ensures easy workpiece insertion and removal, speeding up production cycles. Whether you’re a small shop or a large manufacturing facility, these dies enhance efficiency without compromising quality.
Fierte’s spring loaded helping dies are built to last, reducing the frequency of tool replacements. Their cost-effective pricing, combined with their ability to minimize rework (thanks to consistent results), makes them a smart investment for businesses looking to improve profitability and productivity.
