FAQ for tungsten carbide punches:<\/strong><\/h5>\n
<\/h6>\n
Q1: What are tungsten carbide punches:<\/strong><\/h6>\n

A: Tungsten carbide punches (carbide punches) are precision stamping and piercing tools manufactured from cemented tungsten carbide (WC-Co alloy). They replace high-speed steel (HSS) punches for high-volume processing of hard workpieces, featuring outstanding hardness, wear resistance, and compressive strength.<\/p>\n

 <\/p>\n

Q2: What dimensional tolerances can tungsten carbide punches achieve?<\/strong><\/h6>\n

A: Diameter tolerance: \u00b10.001 mm ~ \u00b10.003 mm for precision electronic micro punches; \u00b10.005 mm ~ \u00b10.01 mm for general stamping punches.
\nLength tolerance: \u00b10.005 mm ~ \u00b10.02 mm.
\nSurface roughness: Ra 0.02\u20130.1 \u03bcm after ultra-fine grinding and mirror polishing.
\nConcentricity: \u22640.002 mm for micro tiny punches (0.1\u20131.0 mm diameter); \u22640.003\u20130.005 mm for standard stepped punches; perpendicularity \u22640.003 mm.<\/p>\n

 <\/p>\n

Q3: What surface treatments are available for tungsten carbide punches?<\/strong><\/h6>\n

A: Super mirror polishing: Reduce friction and prevent material adhesion, ideal for aluminum and copper stamping.
\nPVD coating (TiN \/ TiCN \/ TiAlN): Improve surface hardness, anti-wear and anti-sticking performance, extending service life by 2\u20134 times.
\nDLC diamond coating: For non-ferrous metal, plastic and ultra-thin foil; ultra-low friction coefficient.
\nCryogenic treatment (-196\u2103): Release residual internal grinding stress to boost toughness and lower edge chipping risk.<\/p>\n

 <\/p>\n

Q4: Can custom special-shaped punches be manufactured?<\/strong><\/h6>\n

A: Yes. We produce standard straight punches, stepped shoulder punches, ejector punches, oval\/rectangular\/profile forming punches, micro tiny punches (minimum diameter 1mm), slender long punches and cold forging punches. Customers need to provide 2D\/3D drawings or physical samples for customization.<\/p>\n

 <\/p>\n

Q5: What carbide grades are commonly used for carbide punches?<\/strong><\/h6>\n

A: Low Cobalt (3%\u20136% Co): High hardness (HRA > 91) and excellent wear resistance; suitable for fine blanking of ultra-thin stainless steel, silicon steel sheets, and electronic lead frames; however, the material is relatively brittle and unsuitable for heavy-impact applications.
\nMedium Cobalt (8%\u201310% Co): A general-purpose grade offering the best balance of hardness and toughness; suitable for copper, brass, cold-rolled steel, and standard stamping dies.
\nMedium-High Cobalt (10%\u201312% Co): High toughness; suitable for applications involving moderate impact, such as stamping dies.
\nHigh Cobalt (15%\u201320% Co): Excellent impact resistance; specifically designed for high-impact applications such as blanking thick plates, heavy-duty punching, and cold forging punches.<\/p>\n

 <\/p>\n

Q6: What workpieces are carbide punches suitable for?<\/strong><\/h5>\n

A: Thin metal sheets: Cold rolled steel, stainless steel, copper, brass, aluminum alloy, silicon steel sheet.
\nElectronic components: Lead frames, terminals, connectors, IC pins, battery tab piercing.
\nHardware stamping: Rivets, screw blanks, spring plates, precision gaskets.
\nOther applications: PCB punching, ceramic sheet, graphite and plastic film piercing.<\/p>\n

 <\/p>\n

Q7: What\u2019s your MOQ for standard \/ custom tungsten carbide punches?<\/strong><\/h6>\n

A: Standard stock sizes: small MOQ, sample order acceptable (1\u20132 pcs for testing). Non-standard customized shapes require higher MOQ to cover mold & sintering cost. Please send us inquiries for further information.<\/p>\n

 <\/p>\n

Q8: What\u2019s your production lead time?<\/strong><\/h6>\n

A: Stock ground tungsten carbide punches: 2\u20133 working days.
\nStandard custom carbide punches: 10\u201325 days.<\/p>\n
