Stamping Die Punch

Name: Sheet Metal Die Punch for Fabricators – Frigate
Price: 249.00 USD
Availability: InStock

Stamping Die Punch failures due to fatigue and edge degradation often originate from suboptimal material microstructures and improper heat treatment. Each Stamping Die Punch is manufactured using high-speed tool steels or powder metallurgy variants with uniform carbide dispersion to resist thermal softening and mechanical fatigue during high-load stamping cycles. Secondary cryogenic processing and PVD surface coatings such as AlCrN or TiCN are applied to minimize notch sensitivity and delay microcrack propagation under cyclic impact loading.

Material Specification

D2, A2, M2, SKD11, DC53, Tungsten Carbide (for high-wear applications)

Hardness (HRC)

58-62 HRC (D2, SKD11), 60-64 HRC (Carbide), 52-56 HRC (DC53 for toughness)

Surface Finish (Ra/RMS)

Cutting Edge – 0.2–0.4 µm, Body – 0.8–1.6 µm, Mounting Surfaces – 0.4–0.8 µm

Dimensional Tolerances

±0.005 mm (Cutting Edge), ±0.02 mm (Critical Features), ±0.05 mm (Non-Critical)

Punch Profile Geometry

As per 2D/3D CAD model (DXF/DWG/STEP) with ±0.01 mm profile tolerance

Product Description

Deviation in punch geometry during repeated strokes leads to off-spec components and accelerated die wear. Stamping Die Punch tolerances are controlled to ±2 microns using 5-axis CNC grinding and orbital lapping systems. The tool’s core hardness and face flatness are balanced through multi-stage tempering cycles to maintain dimensional integrity during thermal expansion and high-velocity contact with strip material in progressive and transfer dies.

Cutting Edge Sharpness/Radius

Sharp Edge (≤0.02 mm radius) for blanking, 0.05–0.1 mm radius for forming

Mounting Features

Shank Diameter – h6 tolerance, Bolt Holes – ±0.02 mm, Alignment Pins – H7/g6 fit

Stripper Plate Compatibility

Clearance – 0.05–0.1 mm per side, Guiding Post Holes – ±0.01 mm concentricity

Coating/Surface Treatment

TiN, TiCN, or DLC coating (2–4 µm); Nitriding (for wear resistance)

Certification Standard

ISO 9001, IATF 16949 (Automotive), JIS (Japanese Industrial Standards), ASTM A681 (Tool Steel)

Technical Advantages

Standard punch geometries are inadequate in applications involving asymmetric features or variable material thickness. Each Stamping Die Punch can be custom-formed through wire EDM and plunge grinding to support shearing paths with radius transitions, internal sharp corners, and compound angles. This allows seamless integration into multi-functional dies requiring punching, coining, and forming in a single stroke.

Advanced High Strength Steels (AHSS), electrical steels, and nickel alloys introduce unique wear and galling challenges. Stamping Die Punch edges are engineered with nano-layer coatings and carbide-rich matrixes to maintain compressive strength at temperatures exceeding 400°C. These punches exhibit reduced coefficient of friction and minimal adhesive wear, enabling continuous operation in laminated stack punching and hardened strip applications.

Industry Applications

Automotive Structural Components

Used for high-speed shearing of AHSS and aluminum sheets in body-in-white panel and chassis bracket production lines.

Electrical Motor Laminations

Performs precise punching of stacked silicon steel sheets, maintaining interlaminar insulation and minimal burr for efficient magnetic core assembly.

Aerospace Fastener Holes

Creates high-accuracy holes in titanium or Inconel sheets for fastener alignment in wing ribs and fuselage substructures.

Consumer Electronics Casings

Punches micro-features in stainless steel and aluminum alloys used in precision enclosures for smartphones, laptops, and wearable devices.

Battery Enclosure and Busbar Manufacturing

Processes thin-gauge copper and aluminum foils with minimal edge deformation for high-voltage battery packs and EV busbar assemblies.

Medical Device Stampings

Used for tight-tolerance punching of biocompatible metals like 316L stainless in surgical tools, implant components, and housings.

Thermal Shock and Impact Absorption

Thermal cycling in fast-press operations results in microstructural instability in conventional tools. Stamping Die Punch configurations are designed with controlled thermal conductivity and core resilience, achieved via differential tempering and shot peening techniques. This structure absorbs impact stress and dissipates thermal gradients rapidly, preventing edge microfractures and maintaining cutting edge integrity.

Improper punch clearance leads to excessive burr height and die erosion. Each Stamping Die Punch is manufactured with concentricity maintained below 0.005 mm and shank tolerances restricted to H6. Controlled press-fit geometries ensure minimal lateral movement, preserving optimal clearance between punch and die throughout the tool life cycle.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure dimensional accuracy in Stamping Die Punches for micro-feature punching?

Frigate uses high-precision CNC grinding and in-house lapping processes to hold tolerances within ±2 microns. Each Stamping Die Punch is measured with optical comparators and roundness testers. Punch concentricity and parallelism are verified under SPC protocols. This ensures accurate micro-feature replication in small components like electronics and medical parts.

What edge preparation methods does Frigate use to reduce galling in Stamping Die Punches for aluminum stamping?

Frigate applies micro-polishing and controlled radius formation to the punch edge to reduce material adhesion. Low-friction PVD coatings like AlTiN or CrN are added for thermal stability. Punches are tested in dry and lubricated runs to assess galling behavior. These steps improve tool life and surface finish in aluminum stamping lines.

How does Frigate handle punch customization for non-standard hole geometries in EV components?

Frigate designs Stamping Die Punches with custom profiles using 5-axis wire EDM and 3D contour grinding. Each punch shape is simulated using FEA for stress analysis. Custom punches are validated through sample runs in client tooling conditions. This ensures shape consistency even in non-circular or asymmetric hole patterns.

What treatments does Frigate offer to enhance Stamping Die Punch life in hot stamping operations?

Frigate offers cryogenic treatment followed by high-temperature PVD coatings like AlCrN for heat resistance. Punch cores are tempered for thermal shock absorption and surface hardness stability. The punches are also tested in thermal cycling simulations. This allows reliable punching performance in hot-formed boron steel and press-hardened parts.

How does Frigate address punch-die clearance issues in high-speed progressive tools?

Frigate manufactures Stamping Die Punches with controlled shank tolerances and precise axial alignment features. Clearance zones are optimized using die simulation feedback. All punches undergo test fitting in gauge blocks to verify concentricity. This prevents premature die wear and ensures consistent part shearing in progressive dies.
