What's DPM?

Direct Part Marking (DPM) is a process used to permanently mark a product or component with a unique identifier, typically in the form of a code or symbol. The marking is made directly onto the surface of the material using techniques such as laser etching, dot peening, or chemical etching.

DPM is often used in industries such as aerospace, automotive, and electronics, where traceability and identification of parts is critical for quality control, supply chain management, and product recalls.

Some advantages of DPM over other marking methods such as labels or tags include its durability, resistance to wear and tear, and ability to withstand harsh environments. Additionally, DPM codes can be smaller in size than other marking methods, making them ideal for parts with limited surface area.

DPM codes can be read using various methods such as handheld scanners, machine vision systems, or RFID (Radio Frequency Identification) technology. The data contained in the code can be used for various purposes, including inventory management, production tracking, and quality control.
