The precision specialist.

311 pieces: 50 numbers · 48 symbols · 135 lowercase · 78 uppercase
The professional all-rounder.
The 6mm set strikes the perfect balance between detail and visibility. Supporting both uppercase and lowercase letters, it covers the widest range of professional applications:
230 pieces: 30 numbers · 44 symbols · 78 lowercase · 78 uppercase
The bold statement maker.
The 8mm set is engineered for maximum visual impact. Uppercase-only typography commands attention and reads clearly at distance — perfect for:
114 pieces: 20 numbers · 42 symbols · 52 uppercase
Not all brass is equal. ZHENGFEI uses H62 high-grade brass — the industry benchmark for precision hot stamping dies.
| Property | H62 Brass Advantage |
|---|---|
| Heat conductivity | Transfers heat evenly across the entire stamp face for consistent impressions |
| Hardness | Resistant to deformation under repeated press pressure |
| Machinability | Allows 0.01mm CNC engraving without edge breakout |
| Corrosion resistance | Maintains precision and appearance through years of professional use |
| Surface finish | Smooth brass face releases cleanly from foil and material surfaces |
Every character in the No.19 series is CNC-engraved — not cast — ensuring sharp, consistent edges that last thousands of impressions.
The No.19 stamp set is designed to work with all standard hot stamping machines, including ZHENGFEI’s full range of manual and pneumatic models.
Compatible with any hot stamping machine accepting standard brass type. Stamp body dimensions (7×7×16mm / 10×10×16mm / 14×14×16mm) fit most universal holders.

Q: Can I mix and match pieces from different size sets? A: The 3mm, 6mm, and 8mm sets have different stamp body dimensions (7×7×16mm, 10×10×16mm, 14×14×16mm respectively), so they use different holders. Within each size, all characters are interchangeable freely.
Q: Do the stamps come with a holder/fixture? A: The No.19 sets include the individual brass character stamps. Compatible holders for hot stamping machines are available separately — contact us to confirm the right holder for your machine model.
Q: What machines are these compatible with? A: All standard hot stamping machines. ZHENGFEI stamps are compatible with our full machine range and most third-party machines. Contact us with your machine model if unsure.
Q: Can you make lowercase letters for the 8mm set? A: Yes — via our custom stamp service. The standard 8mm set is uppercase-only, but we can CNC-engrave any character at 8mm size. Contact us for a custom quote.
Q: What is the recommended temperature for leather stamping? A: Start at 130–150°C and adjust based on leather thickness and finish. Always test on scrap leather first.
Q: How durable are the stamps? A: H62 brass is extremely durable. With proper care (no abrasive cleaning, dry storage), professional-use stamps maintain precision for tens of thousands of impressions.
Q: Do you offer training for new users? A: Yes — we provide free technical guidance for new customers, including recommended settings for common materials. Contact us and our team will support your setup.
Q: What if I need a font that isn’t in the No.19 standard range? A: Our custom font service handles any typeface — send us your font file or brand guidelines and we’ll produce it. Free design, factory-direct pricing.
