Inside the KMF-20 Fiber Laser Marking Machine — Marking System Engineering Highlights
The blocks below take you inside the KMF-20 Fiber Laser Marking Machine — each illustrates one specific optical, laser-source, or control-system choice that defines marking depth, contrast, and throughput. Topic-by-topic below: Permanent Identification Marker, Wide Range Of Applications, and High Precision.
Permanent Identification Marker
Laser engraving or marking lasts a lifetime. These permanent markings or engravings are resistant to light, water or chemicals. Laser markings remain legible for the life of the product. Lifetime markings of serial numbers or model numbers make them useful for a lifetime.
Wide Range Of Applications
Kasu laser markers are controlled by advanced software for seamless graphic design and marking. Its wide range of applications, covering a variety of industries such as electronics, apparel, furniture, leather, packaging, etc., ensures efficient and accurate marking solutions.
High Precision
The KMF-20 can transmit complex designs, graphics, and even tiny symbols or numbers. Since the laser beam is controlled by computer software, it moves and focuses small dots that can follow complex patterns and designs. The accuracy of the material surface design and transfer improves product quality and performance.

Frequently Asked Questions About the KMF-20 Fiber Laser Marking Machine
What does the KMF-20 fiber laser marker do that a CO2 laser can't?
Fiber lasers operate at ~1064 nm wavelength â absorbed efficiently by metals (stainless steel, brass, aluminum, copper, titanium) but not by most organic materials. CO2 lasers (10,600 nm) are absorbed by organics but reflected by metals. The KMF-20 marks deeply and permanently into bare metal â for serial numbers, barcodes, logos, traceability codes â where a CO2 laser would do nothing. Used in industries that require permanent ID on metal parts.
Which industries need fiber laser marking, and what regulatory requirements push it?
Top 2025 demand:
- Medical devices: FDA UDI (Unique Device Identification) requires permanent marking on surgical instruments and implants
- Automotive parts: VDA 6.3 supplier requirements for traceable serial numbers on safety-critical components
- Tool & die shops: customer-required serial numbers on production tools
- Aerospace: FAA traceability requirements for serialized components
- Electronics: barcode marking on metal enclosures and PCBs
KASU ships KMF-20 to medical-device OEMs in Germany / Italy and automotive tier suppliers in Mexico / India.
What marking depth and contrast does the KMF-20 produce on different metals?
| Metal | Marking type | Typical depth | Contrast |
|---|---|---|---|
| Stainless steel 304/316 | Annealed (dark oxide) | Surface only | Dark gray / black |
| Stainless steel | Deep engrave | 0.05-0.3 mm | Dark indented |
| Anodized aluminum | Color strip | ~5 µm | White on color |
| Brass / copper | Engrave | 0.05-0.2 mm | Polished bright |
| Titanium | Heat-tint color | Surface | Rainbow / oxide |
| Painted / coated metal | Burn-off | Coating only | Base metal bright |
What's the laser source lifespan and total cost of ownership for the KMF-20?
The fiber laser source has a rated lifespan of 100,000 working hours (~11 years of 24/7 operation). Compared to CO2 tubes (~8,000-10,000 hrs requiring periodic replacement at $300-500 each), fiber is essentially zero-maintenance for the laser source over a typical equipment lifetime. Add ~$0 in laser consumables vs ~$1,500-2,000 over 5 years for CO2. Power consumption: ~250 W during marking â about one-fifth of an equivalent CO2 + chiller setup.
What software handles barcode / QR / serialization on the KMF-20?
KASU’s bundled EzCAD-compatible marking software handles all standard 1D barcodes (Code 128, Code 39, EAN, UPC), 2D codes (QR, DataMatrix, PDF417), serial-number auto-increment, date/time auto-insert, and database lookup for variable data marking. Import CSV for batch marking (e.g., 10,000 unique serial numbers in one production run). Supports common formats: AI / DXF / PLT / BMP / JPG.
