What Do Our Terms Mean?
The alternative to DPM is to apply a mark to a label or sticker which is then attached to the component.
Pryor's standard machines use an electrically driven solenoid to actuate the stylus, but pneumatic actuation is also available for deepÃ‚Â markingÃ‚Â or fast marking.
Dot peen marking provides fast, accurate, low-stress marking and can mark through coatings or film on the material surface.
RRES 90003 stands for Rolls-Royce Engineering Specification. It is a global part marking specification reflecting international standards to support quality requirements for permanent part identification in line with Spec 2000.
Both of these specifications control marking methods used, specify parameters for marking permanent part identification and prevent the use of unsuitable markings in line with machine-readable 1D and 2D codes.
This standard is a comprehensive specification that introduced the requirement to identify each part withÃ‚Â a unique serial numberÃ‚Â thatÃ‚Â enables any part anywhere in the world to beÃ‚Â identified as individual and distinct from anyÃ‚Â other part, however similar that other part mayÃ‚Â be. The identification method specified is a permanentlyÃ‚Â marked barcode or 2D data matrix code thatÃ‚Â should remain on the part throughout its entireÃ‚Â life.
The standard implements a method to storeÃ‚Â information that can be read in an automatedÃ‚Â manner Ã¢â‚¬" Automatic Identification and DataÃ‚Â Capture (AIDC), improving the reliability andÃ‚Â accuracy of information shared. Pryor's software and vision systemsÃ‚Â fully support the reading and management of barcoded data.
Spec 2000 specifies full lifecycle tracking and traceabilityÃ‚Â of serialised parts, allowing for the use of automated processes in parts handling. The code simply points to a database or tracked information thatÃ‚Â is used for many daily processes, including:
Ã‚Â - provisioning
Ã‚Â - processing warrantyÃ‚Â claims
Ã‚Â - tracking part installation and removalÃ‚Â time
Ã‚Â - tracking maintenance and repairÃ‚Â history
From September 2016, all medical class III devices and instruments that require direct part marking (DPM) must also carry a UDI. Class II and Class I devices will require UDI from September 2018 and September 2020 respectively.
This system will allow greater accuracy in reporting and traceability as well as reducing medical errors by allowing health care workers to quickly identify instruments.

A Data Matrix code is the name given to a particular type of 2D barcode as defined by the ISO/IEC 16022 international standard. Each Data Matrix has 2 solid adjacent borders that form an 'L' shape. This 'L' is called a "finder pattern" and ensures that the code can be read regardless of its orientation.
Data Matrix codes are formed by a series of equally sized squares and so are ideal for marking withÃ‚Â dot-peenÃ‚Â machines.
Each Data Matrix can store up to 3116 numbers orÃ‚Â 2335 alphanumericÃ‚Â characters from the full ASCII range, and this data can even be encrypted for security purposes.
Another key advantage of a Data Matrix is error proofing. Codes can be designed to ensure that even when partially damaged or obscured a majority of data can be recovered from them.
A QR code (Quick Response Code) is another type of 2D barcode, first developed in the Japanese automotive industry, but has since become widely used in advertising applications. The amount of data that can be stored in a QR code depends on the data type and the error correction level. There are four correction levels, the higher the level, the less storage capacity. A QR code is recognisable by three distinctive squares at the corners.
Pryor supplies aÃ‚Â range of productsÃ‚Â for marking, reading and managing 2D barcodes.Ã‚Â Data Matrix codes are believed to be the more secure (less hackable) codes and areÃ‚Â favoured where high security is deemed important.Ã‚Â Pryor'sÃ‚Â dot-peen,Ã‚Â laser,Ã‚Â chemical etchingÃ‚Â andÃ‚Â inkjetÃ‚Â machines are all suitable for Data Matrix marking applications.Ã‚Â Laser,Ã‚Â InkjetÃ‚Â andÃ‚Â chemical etchingÃ‚Â are suitable for marking QR codes.
The IAQG have implemented standards regarding the direct part marking of aerospace components, such as the type of styli to be used in dot-peen marking machines.
It is an entry level, benchtop dot peen marking machine.Ã‚Â
