HOW TO SELECT THE RIGHT MARKING MACHINE TECHNOLOGY
For many metals and some plastics, pin marking offers the potential for cost-effectiveness and deep, indelible impressions.“There’s more to your decision than simply laser marking vs. pin marking,” says Conaway. “For one thing, there are several types/wavelengths of lasers, and different materials respond best to one or the other: Pulsed fiber lasers are suitable for most metals and some plastics. Short-pulse, diode-pumped solid state lasers are ideal for metals and plastics when you need fine detail. CO2 laser marking machines yield superior results on glass, or on organic materials like plastics, wood, rubber, paper, and cardboard.”Jessica
Information content defined clearly, early in the game, could head off expensive course corrections later on. Do give that content some extra thought: You might realize that adding a little more information could boost productivity and enhance ROI. For example, will the barcode or part number you had in mind make full use of a new device’s capacity? Or could a supplementary tracking number or logo contribute value further down the line?Jamarion
Readability means a mark’s effectiveness in communicating with a vision system or a human eye. It’s mostly determined by contrast and resolution.Contrast is the difference in reflectivity or texture between the mark and the background. High contrast is essential for accurate, consistent readability. Surface finishes, marking tools, and available lighting all contribute to contrast.Marisa
Resolution, or image quality — usually expressed in dots per inch — is especially critical for detailed images like 2D barcodes; for branding elements like logos; and for small marks of all kinds. Higher is usually better, but the sweet spot for your application will depend on a variety of factors.ropingvacation
The laser head is a pencil-like light emitting gun that projects a beam at the engraving surface, guided with the aid of a computer-aided controller that imprints patterns on the surface.Gun laser machines can engrave surfaces consisting of metals, plastics, lined metals or glass depending on their design and laser beam wavelengths.
