The Standard Lower Die is a core bending die engineered for professional sheet metal processing, developed by Fierte—an industry specialist in bending tools and crowning tables. This high-performance press brake die is crafted from top-grade steels including 42CrMo4 and C45, undergoing strict whole body heat treatment to achieve a hardness of HRC48-50. Combined with precision grinding technology, it delivers consistent accuracy and reliability, meeting the rigorous demands of modern sheet metal fabrication. Whether for small-batch customization or large-scale production, this die stands out as a versatile and durable solution for bending operations.
The Standard Lower Die features meticulously calibrated dimensions to ensure optimal bending performance: key parameters include 1.5mm, 8mm, 13mm, 20mm, and 37mm, with critical tolerances such as 15+0.02mm for precise alignment with press brake systems. The die integrates an 86° angle and R1 radius design, which minimizes material springback and ensures uniform bend formation. Every dimension is verified through rigorous quality control to guarantee seamless integration with existing production lines.
To cater to diverse working environments, the Standard Lower Die offers three high-quality surface treatment options:
Blackening surface treatment: Enhances corrosion resistance and provides a sleek, professional appearance, suitable for general indoor applications.
Sandblasting surface treatment: Improves wear resistance and grip, ideal for high-friction or dusty production settings.
Sandblasting + blackening combination: Delivers maximum protection against corrosion and wear, perfect for harsh industrial environments or outdoor-facing components.
Each finish undergoes uniform processing to ensure consistency and longevity.
The Standard Lower Die adopts a one-piece structural design, reinforced by whole body heat treatment to enhance overall strength and impact resistance. This integrated structure eliminates weak points, ensuring stable performance even during high-volume, continuous production runs. The die’s base (37mm thickness) provides robust support, distributing pressure evenly across the working surface to prevent deformation and extend service life.
Engineered with precision grinding technology, the die’s working surface boasts exceptional flatness and smoothness, guaranteeing tight bending tolerances. The 86° angle and R1 radius are precision-machined to minimize material springback, a common challenge in sheet metal bending. This optimization ensures that each bent component meets exact design specifications, reducing rework and improving production efficiency. The mechanism also reduces friction between the die and sheet metal, enhancing both precision and material integrity.
At the heart of the Standard Lower Die is its premium material selection: 42CrMo4 and C45 steels are chosen for their superior mechanical properties, including high tensile strength, toughness, and wear resistance. These steels undergo strict quality inspection (including chemical composition and mechanical performance tests) before manufacturing, ensuring compliance with international industry standards.
Critical components of the Standard Lower Die are precision-machined to tight tolerances:
The working surface: Polished to a smooth finish via precision grinding, ensuring consistent contact with sheet metal.
Guiding structures: Calibrated to 15+0.02mm for perfect alignment with press brake punches, eliminating misalignment issues.
Base plate: 37mm thick for stable support, with reinforced edges to resist warping under high pressure.
All standard parts are designed for easy maintenance and replacement, reducing downtime and operational costs.
Thanks to whole body heat treatment (HRC48-50) and premium 42CrMo4/C45 materials, the Standard Lower Die withstands thousands of bending cycles without wear or deformation. Its robust construction ensures long service life, reducing replacement frequency and lowering total cost of ownership.
Precision grinding and strict dimensional control deliver consistent, accurate bends with tight tolerances (±0.02mm for key dimensions). The optimized 86° angle and R1 radius design minimizes springback, ensuring that finished components meet design requirements without rework.
Compatible with multiple press brake brands and sheet metal materials (carbon steel, stainless steel, aluminum, etc.), the Standard Lower Die adapts to diverse production needs. It is suitable for bending thin sheets (0.5mm) to thick plates (10mm), making it a versatile tool for any sheet metal shop.
Combining reliability, durability, and low maintenance requirements, the Standard Lower Die offers excellent cost-effectiveness. Its long service life reduces replacement costs, while precision performance minimizes material waste. Additionally, the 18-20 day lead time ensures timely delivery to meet production schedules.
