In the field of precision sheet metal fabrication worldwide, Amada press brake dies—also known as Amada press brake tooling, including matched Amada punch and die sets—follow the Promecam/European standard and have established themselves as an industry benchmark. After decades of market validation, this system has become one of the mainstream standards for CNC press brakes globally. Whether it is original Amada press brakes (HG, HFE, HRB series, etc.) or domestically manufactured CNC press brakes designed to European standards, all are seamlessly compatible with this standardized tooling.
Distinct from American-style non-standard tooling that relies on side clamping, the Amada European standard system offers three core advantages: standardized tang design, modular segmentation, and high-precision interchangeability, breaking down brand barriers. From large sheet metal factories in Japan, South Korea, Europe, and the United States to small and medium-sized fabrication shops in China, the Amada system has become the preferred tooling system for high-mix, low-volume flexible sheet metal production, occupying the mainstream share of the mid-to-high-end precision press brake tooling market.
Core Design Features of the Amada Tooling System
Standardized Tang Design: 13mm Promecam Standard
The Amada system uses the European Promecam-exclusive 13mm tang design, with its core being the shoulder-load bearing design—the tool load is transferred to the clamp through the tool body’s shoulder, rather than relying on the tang. This distinguishes it from the American-style 12.7mm straight tang, which depends on side clamping.
Key advantages include: safety groove preventing the tool from falling even if the clamp loses pressure; broad compatibility with Amada one-touch holders, SGRIP quick clamps, and hydraulic CS clamping systems; and fixed height design (AFH series) with a uniform industry-standard 120mm height across all punches per Promecam specs, eliminating Z-axis adjustment after setup—truly plug-and-bend operation.
High Interchangeability and Strong Versatility
Punches and dies of the same specification but different profiles can be freely interchanged in the same holder—no shimming required. Standard tooling can be split into segmented modules and combined as needed, with no steps or marks at the joints. Compatible with both original Amada press brakes and domestic European-standard CNC equipment, new or old machines can use them interchangeably.
Modular Segmented Design for Reduced Changeover Time
Segmented modules allow flexible workstation configuration. A single clamping beam can fit multiple bending stations at once, enabling “one setup, multi-step continuous bending.” This effectively reduces tool changeover time and is particularly suitable for small-batch, high-mix order production.
Common Tooling Types in the Amada System
Punches – Full Range
88°/90° standard straight punches are used for general bending, covering most conventional applications. Gooseneck punches are the workhorse tool, ideal for U-channels and regular return flanges, offering high strength. Sash punches (window punches) are designed for deep boxes, narrow flanges, and Z-bends, effectively avoiding interference. Acute angle punches (26° or 30°) are used for hemming or high-springback stainless steel. Flattening punches complete secondary operations such as edge flattening and closed hems. Radius forming punches are used for large arc or specific radius curved profiles.
Dies – Mainstream Categories
Single-V dies cover the full range from V6 to V40, suitable for material thicknesses from 0.5mm to 6.0mm. Multi-V dies integrate multiple specifications into one body, reducing changeover frequency. Quick-change rail dies achieve second-level tool changes when used with quick-change systems. Mark-free bending dies adopt polyurethane inserts or wiping die structures to avoid indentations on stainless steel and polished aluminum sheets.
Segmented Tooling and Custom Non-Standard Dies
Standard segmented tooling sets support box bending production. Common segment sizes include 10mm, 15mm, 20mm, 50mm, 100mm, 200mm, 300mm and 835mm. Additionally, non-standard products such as Z-bend forming dies and special-angle profile dies are available to meet diverse forming requirements.
Precision, Material and Heat Treatment: Industry High-Standard Manufacturing Specification
The true value of Amada-compatible tooling is reflected in the comprehensive benchmarking of material, hardness, and precision.
Raw Material: Made of 42CrMo (42CrMo4) high-strength alloy steel, consistent with the material used in Amada’s original AFH series tooling. This material offers excellent fatigue resistance and wear resistance, meeting the demanding requirements of high-load, high-volume production.
Machining Precision: The full range of tooling undergoes precision grinding, with critical dimensional tolerances controlled to ±0.02mm. When segmented tooling is joined together, different batches maintain good straightness without requiring shim calibration.
Hardness Treatment:
- Standard Series: Full-body hardening treatment achieves a hardness of HRC 47±2, with consistent hardness from surface to core
- 30° Acute Punches: Working edges are surface hardened to HRC 60±2 for anti-wear, with base body kept at HRC 47±2
- Premium Long-Life Dies: Surface hardness reaches HRC 55, with significantly enhanced wear resistance through special treatment processes
AFH Fixed Height Series: Punches are unified at a 120mm standard height—whether straight punches, gooseneck punches, sash punches or acute punches, all heights are perfectly consistent, eliminating Z-axis origin adjustment after setup.
Durability: All finished tooling goes through stress-relief treatment, resisting deformation during long-term mass production. The full-body hardening process ensures that worn tooling can be “regenerated” through regrinding, offering a service life far exceeding that of cheaper induction-hardened tooling.
Multi-Industry Application Scenarios
Amada press brake tooling adapts to sheet metal fabrication needs across multiple industries.
- Precision Instruments and Medical Equipment: Meets high-precision bending requirements with stringent tolerance control.
- Electrical Enclosures and Server Cabinets: High-volume box forming emphasizes efficiency and consistency.
- Construction Machinery: Involves bending of 3–6mm thick plates and high-strength steel housings, requiring larger V-die openings (e.g., V40 or above) to match high tonnage demands.
- Home Appliances and Kitchenware: Primarily processes stainless steel and decorative aluminum materials, paired with polyurethane or wiping mark-free dies to effectively protect surfaces.
- New Energy Storage and Rail Transit: Supports sheet metal fabrication for ancillary components, balancing precision with batch stability.
Summary
In summary, Amada press brake tooling relies on its standardized tang design, excellent interchangeability, and stringent precision manufacturing processes.
