Metal hardness testing standards are one of the most common sources of supplier disputes in CNC machining and die casting. A drawing says HRC 55, a purchase order says HB 200 max, and the incoming report does not match. Then the same questions repeat: which hardness scale was used, which ASTM standard or ISO standard […]

Vapor smoothing can make CNC machined plastics and 3D printed plastics look clearer and more premium. But many teams treat vapor smoothing and vapor polishing like a magic polish. They run parts, see haze or distortion, and then burn weeks on rework. They also lose tolerance control when edges round or surfaces reflow unevenly. In

Machining TPU parts looks simple until the material starts moving during CNC machining. TPU is flexible, elastic, and heat sensitive, so it behaves less like a rigid plastic and more like a springy system in thermoplastic polyurethane cutting. Clamp it like aluminum and it distorts. Cut it like ABS and it smears, especially in CNC
