subject: Direct Part Marking [print this page] Direct Part Marking (DPM) is a process to permanently mark parts with the help of a Laser Marking System. In today's date Laser marking is the most effective marking. Laser marking is fast marking technology which can be used on hardest materials such as carbides, metals, plastic and Titanium. Industrial part marking equipment enables to identify products for complete traceability.
The process of Direct Part Marking is used by manufacturers to ensure reliable traceability of their parts and products in the long run. Direct Part Marking helps for data logging for safety, conforming to various safety regulatory requirements and also in warranty issues.
Following are the types of the marking used:
1. Dot Marking
2. Laser Marking
3. Scribe Marking
4. Electrochemical Marking
5. Engraved Marking
Operation:
Direct part marking is a 2-dimensional barcode which offers lifetime traceability for item components. Usually these codes appear very tiny in the normal vision; however, they contain all the critical information about the items. Since the codes are machine readable, any possible human error is removed. Of many common direct part marking methods available in the industry, Inkjet Part Marking technique is the most popular for Metal Marking and is used mostly in the aerospace, electronics, automotive, lumber, home building products, food, medical and packaging industries. This type of marking produces the best quality marks possible on most building products.
Advantages:
Industrial manufacturing requirements for indelible direct part marking containing machine vision codes which are growing exponentially. The military requirements, manufacturers of commercial industrial products ranging from automotive, packaging, and pharmaceutical to electronic and consumer goods are aggressively adopting similar standards. Direct part marking enables unit level tracking of a product from the time of manufacturing until the end of its useful life. The powerful combination of laser technology and machine readable vision codes enables absolute product authentication to track, and trace. This is invaluable in the production process, distribution chain, and to end users and consumers.
Direct Part Marking can be applied on following Materials:
