SKH51 misumi punch TiCN coating stamping die punches for metal stamping mold

1. Core TiCN Coating Advantages: Redefining Punch Durability & Stability

• Ultra-High Hardness & Wear Resistance: The TiCN coating achieves a Vickers hardness (HV) of 2800–3200, forming a dense, rigid protective layer on the punch surface. This reduces abrasive wear caused by repeated contact with metal workpieces (e.g., steel, aluminum) by up to 70% compared to standard punches, extending the tool’s service life by 2.5–3 times in continuous stamping operations. For high-volume production lines, this translates to fewer tool changes, lower maintenance costs, and reduced downtime.
• Excellent Thermal Stability & Oxidation Resistance: TiCN coating maintains stable performance at temperatures up to 450°C, avoiding softening, peeling, or oxidation caused by frictional heat during high-speed stamping. This stability ensures consistent punch precision even in long-running production cycles, preventing dimensional deviations that could compromise the quality of stamped parts.
• Low Friction & Anti-Adhesion Properties: The coating’s smooth surface (surface roughness Ra ≤ 0.03 μm) minimizes friction between the punch and workpiece materials, reducing the risk of material adhesion— a common issue with sticky metals like aluminum or copper. This not only ensures clean, burr-free stamped edges but also reduces the need for frequent lubrication, simplifying maintenance and improving production efficiency.

2. Precision Engineering: Aligned with Misumi Stamping Dies & Strict Tolerance Standards

• Dimensional Accuracy for Seamless Die-Punch Matching: The punch’s shank, head, and working surface are machined using CNC grinding technology with a dimensional tolerance of ±0.005 mm. This ensures a perfect fit with Misumi stamping dies, eliminating gaps that could cause workpiece deformation or uneven stamping force distribution. Whether used for blanking, piercing, or forming, the punch-die combination delivers consistent part quality batch after batch.
• Optimized Head Design for Versatile Stamping Needs: The punch head is available in multiple standard geometries (e.g., round, square, rectangular) to match common stamping die configurations, covering diverse application scenarios from small electronic component piercing to large hardware blanking. For custom stamping requirements, Misumi also offers tailored head designs—all coated with TiCN to maintain the same high performance across non-standard shapes.
• High-Strength Base Material for Structural Integrity: The punch’s core is made of premium alloy steel (e.g., SKH-51 high-speed steel or SKS-3 tool steel) with a heat-treated hardness of HRC 60–63. This base material provides exceptional tensile strength and impact resistance, complementing the TiCN coating’s wear protection to prevent punch bending or chipping during high-impact stamping—critical for processing thick or high-strength metals.

Certifications

• Automotive Manufacturing: Ideal for stamping high-volume automotive components (e.g., sheet metal brackets, electrical connector terminals) using Misumi stamping dies. The TiCN coating’s wear resistance handles the repeated stamping of steel or aluminum sheets, while the punch’s precision ensures consistent part dimensions—meeting automotive industry quality standards (e.g., IATF 16949).
• Electronic & Electrical Industry: Used in stamping small, precise parts like circuit board contacts, terminal blocks, and sensor housings. The punch’s tight tolerance (±0.005 mm) and anti-adhesion coating prevent damage to delicate electronic materials, while its compatibility with Misumi’s micro-stamping dies supports the miniaturization of electronic components.
• Hardware & Precision Engineering: Suitable for manufacturing hardware parts (e.g., washers, fasteners, springs) via Misumi stamping dies. The TiCN coating’s durability reduces tool replacement frequency in high-volume hardware production, while the punch’s stable performance ensures uniform part quality—critical for hardware that requires consistent fit and function.
• Aerospace & Medical Devices: For low-volume, high-precision stamping of aerospace components (e.g., lightweight alloy brackets) or medical parts (e.g., stainless steel instrument components), the punch’s combination of TiCN coating protection and Misumi’s precision engineering meets the stringent quality and reliability requirements of these industries.
