The core and cutting edge of Bescomt stamping dies are made of SKD11 or DC53 tool steel. SKD11 offers high wear resistance and good hardenability, ideal for long‑run mass production. DC53 provides approximately twice the toughness of SKD11 while maintaining high hardness, making it especially suitable for stamping operations with impact loads. The die set is made of 45# steel to ensure overall rigidity and stability.
 | Every die is fully ground to achieve a smooth surface free of rough spots, which reduces friction and prevents scratching of the strip during stamping. In addition, chamfering is applied to the edges of the die to eliminate sharp corners – protecting operators and preventing surface damage to the sheet metal, thus improving finished part quality. |
Bescomt applies a rigorous heat treatment cycle to the core: first annealing to relieve internal stress and improve machinability, then quenching to achieve high hardness, and finally tempering to adjust toughness, prevent brittle fracture, and stabilize dimensional accuracy. This heat treatment ensures that the die has sufficient hardness to resist wear while avoiding chipping under impact.
Based on the customer‘s specific part geometry, material thickness, and precision requirements, Bescomt provides fully custom die designs. Notably, we can incorporate angled surfaces on the die to help scrap fall away smoothly, preventing scrap from sticking or clogging the die – which significantly improves the reliability of progressive stamping. This feature is especially effective for materials prone to galling, such as high‑strength steel and stainless steel.
Bescomt dies are equipped with both internal guide posts (for precise alignment of punch and die) and external guide posts (to increase the overall rigidity of the die set and resist lateral forces). The combination significantly improves guiding accuracy, reduces uneven wear, extends die life, and ensures consistency and stability of stamped parts.
A standard stamping die consists of several key components, each playing a critical role in ensuring accuracy and stability:
Punch: The upper part of the die that provides the force to shape the material.
Die Block: The lower part of the die that holds the material and defines its final shape.
Stripper Plate: Used to remove the metal from the punch after the operation, preventing sticking.
Guide Posts / Pins: Ensure exact alignment between the upper and lower halves, avoiding misalignment and die damage.
Bescomt stamping dies are built on premium tool steels, fine grinding, chamfering, and scientific heat treatment to achieve high precision and long service life. Custom design – including scrap‑drop angles and internal/external guide posts – addresses the most common stamping die issues: wear, scratching, scrap sticking, and misalignment. Whether you need a simple punching die or a complex progressive stamping die, Bescomt offers professional and reliable solutions.
