Fierte, a trusted leader in sheet metal processing solutions, introduces our industry-defining Deep Insert Dies – the ultimate bending tool for professionals seeking uncompromised precision and durability. Engineered to integrate seamlessly with all types of press brake machines, these Deep Insert Dies are crafted from top-tier steels and optimized through advanced manufacturing processes, making them a cornerstone for heavy-duty industrial projects and precision fabrication alike.
Our Deep Insert Dies stand out for their versatility, compatibility with renowned press brake brands such as Amada/Promecam, Trumpf/Wila, and Bystronic/Beyeler, and commitment to quality that minimizes downtime and maximizes productivity. Every unit undergoes rigorous precision grinding and quality inspections, ensuring consistent bend angles, smooth workpiece finishes, and long-term reliability. Whether you operate a small workshop or a large-scale manufacturing facility, our high-quality Deep Insert Dies deliver cost-effectiveness without sacrificing performance – a true asset for competitive sheet metal processing.
At the core of our Deep Insert Dies lies a choice of premium-grade steels: 42CrMo4, 42CrMo, and C45. These materials are globally recognized for their exceptional tensile strength, wear resistance, and toughness, enabling the dies to withstand repeated high-pressure bending cycles without deformation or premature wear. Unlike low-grade alternatives that require frequent replacements, our high-performance steel construction guarantees extended service life and reduced maintenance costs.
Each Deep Insert Die undergoes whole body heat treatment calibrated to a hardness rating of HRC48-50. This critical process ensures uniform hardness across the entire tool – from surface to core – enhancing structural integrity and stability during operation. Whether bending thick steel plates or thin aluminum sheets, the heat-treated design maintains precision, delivering consistent results that minimize material waste and rework.
We offer three specialized surface treatments to suit diverse operational needs: Blackening, Sandblasting, and Sandblasting + Blackening. Blackening provides a sleek, corrosion-resistant finish ideal for indoor workshops; Sandblasting creates a textured surface that improves grip and reduces slippage; and the combined treatment offers the best of both worlds – enhanced durability and visual appeal. Each application is executed with precision to protect against rust, wear, and environmental damage.
Our Deep Insert Dies are engineered to fit an extensive range of press brake types, including LVD type, American standard type, Gasparini type, Colgar type, and Ajial-Axial type machines. This broad compatibility eliminates the need for custom adapters, saving time and resources while ensuring seamless integration with your existing equipment.
Advanced precision grinding technology ensures tight tolerances and smooth surfaces on every Deep Insert Die, guaranteeing accurate, consistent bends. Our manufacturing process adheres to international quality standards, and each unit undergoes 100% inspection before shipment. The result is a bending tool that delivers reliable performance in even the most demanding applications, helping you meet tight deadlines and maintain high production standards.

We understand that no two sheet metal projects are the same – which is why we offer comprehensive Custom Deep Insert Dies services. Our in-house R&D team of experienced engineers collaborates closely with you to design tools aligned with your press brake model, workpiece specifications, and production goals. Whether you need dies of specific lengths, widths, hardness levels, or bending angles, we adapt our designs to meet your exact requirements.
For less common or custom-built press brake models (such as Colly type machines), our team engineers Deep Insert Dies that fit seamlessly without modifications. Simply share your equipment’s specifications, and we’ll ensure perfect integration with your workflow.
Our technical department provides end-to-end support throughout the customization process – from initial design consultations to post-delivery troubleshooting. We also welcome on-site inspections, allowing you to witness our manufacturing process and quality control measures firsthand, ensuring complete confidence in your custom tools.


Our Deep Insert Dies are crafted from premium 42CrMo4, 42CrMo, and C45 steels, paired with whole body heat treatment (HRC48-50) and precision grinding. This combination ensures exceptional wear resistance and structural integrity, enabling the dies to withstand thousands of bending cycles without deformation.
Yes! Our dies are compatible with Trumpf/Wila, Amada/Promecam, Bystronic/Beyeler, and most major press brake brands. Share your machine’s model details, and we’ll confirm compatibility or offer customization if needed.
For outdoor storage, we recommend Sandblasting + Blackening, as it provides superior corrosion resistance against moisture and environmental elements. Indoor users may opt for Blackening or Sandblasting for cost-effectiveness.
Yes! We provide sample Deep Insert Dies for quality testing. The sample lead time is 15-18 days, and the sample cost can be deducted from your bulk order if you proceed with production.
