Jewellery Laser Hallmarking Machines

Laser marking is an etching process; therefore it does not cause any bruising or distortion of the metal. It is possible to mark both flat and curved surfaces. Laser hallmarking does not require any physical contact with the item. A very precise fiber laser-engraving machine applies it.Laser marking can mark a variety of materials such as steel, aluminum, stainless steel, polymers, and rubber. It is often used to identify parts and products with 2D barcodes (data matrix codes or QR codes), alphanumerical serial numbers, VIN numbers, and logos.Hallmarking is the accurate determination and official recording of the proportionate content of precious metal in precious metal articles. Hallmarks are thus official marks used in many countries as a guarantee of purity or fineness of precious metal articles.
