Graphite isn’t magnetic like iron; it’s diamagnetic and weakly repulsive in practice. That sounds simple, yet many people “prove” graphite is magnetic by testing pencil lead. The problem is contamination and setup: iron dust on a bench, steel debris on a magnet, or clay/binders in pencil cores can create a misleading pull and a lot […]

Laser marking vs laser engraving sounds like a small wording choice. In production, it can decide whether your metal part passes inspection or comes back for rework—especially when you’re working with a manufacturing partner like HM CNC machining and die casting supplier to keep traceability consistent from first article to full production. A mark that

Snap fits look simple, but production failures are predictable: root cracking or whitening, assembly force variation, and retention loss from creep. Many teams also learn the hard way that the “same” snap geometry can work in a CNC prototype yet fail after switching to injection molding. Draft, shrink and warp, knit lines, and surface finish
