"How To. . ." FAQ's
There is a huge variety of different plastics, some being harder to mark and some being easier (harder and glass reinforced plastics are generally easier to mark). Therefore, we recommend that you send us some samples for testing to enable us to deduce the best marking method for your requirements.
To get a deeper mark in hard materials we manufacture pneumatically powered dot peenÃ‚Â and deepÃ‚Â scribeÃ‚Â marking machines.
Chemical etch and laser markingÃ‚Â machines are capable of marking much harder materials as they do not indent the surface.
Many of Pryor's hand toolsÃ‚Â and engraved diesÃ‚Â will mark materials with a hardness of up to around 37 - 40 Rockwell C. However, engraved dies can be specially manufactured from High Speed Tool Steel upon request, which makes these capable of marking materials with a hardness of up to around 50 Rockwell C.

For critical applications our standard dot peenÃ‚Â and scribeÃ‚Â marking machines can be set to make very light marks. Pryor's expertise in these critical applications is unrivalled and we will help you set up the machine for your application.
Our hand toolsÃ‚Â can be supplied as dot stress or mini stress versions which cause lower stress impact on the marked surface.
Pryor's stand-alone machine controllers and windows based softwareÃ‚Â both feature automatic serial numbering as standard.
Serial numbers can be set for a specific mark layout, or globally across all marks made. The user can completely customise the length and format of the serial number, the increment and the frequency of the increment. For example, if the same serial number is to be marked on same part in 2 different places, the frequency of the increment would be every 2 marks.
Via the auto save feature, the serialisation will continue where it left off when the machine is turned off and on again.
Serialisation can also be completed manually, using a Pryor number marking head, where the serial number is completely selectable by rotating the wheels. The automatic number marking head increments automatically each time the actuating lever is pressed.Ã‚Â
If you want to mark along the same point on the circumference (i.e. along a straight line) then a PortaDot with a V MaskÃ‚Â will be ideal for larger, heavier or immobile parts. Either a Cabinet LaserÃ‚Â or a bench mounted dot peen marking machine, such as a BenchDotÃ‚Â or a Markmate, will be ideal for marking for smaller, lighter and mobile parts.
If you want to mark around the circumference of the component and the diameter of the part is less than 200mm, the circumferential fixtureÃ‚Â can be used with either a Cabinet Laser or a bench mounted dot marker. However, this may not be as suitable as other options when marking very heavy parts due to the strain on the motor.
For heavier and larger parts, a multi-axis marking station or robotic marking solutionsÃ‚Â are likely to be the best solution. However, if you are marking many parts of the same type (or very similar), we may be able to develop a more suitable custom marking solutionÃ‚Â for you.
Alternatively, if you already have suitable machinery and are making repeat marks, Pryor also manufactures custom designed roller dies. These can be mounted onto your rotating shaft to mark around the circumference of the part.
You can also mark anodised aluminium with a scribe markerÃ‚Â or a dot marker. The scribe marker scratches the surface, allowing the metal beneath to show through. However, sometimes the edges are not as clean as with a laser marker.
Dot marking is never as clear as laser marking or scribe marking because the anodised layer remains intact which results in less contrast. The mark can sometimes be more difficult to see.
Roller diesÃ‚Â are also able to mark on hot surfaces because they only require a brief contact with the hot material. Most marking devices that mark at speed prevent annealing of the marking tool. For this reason, marking tools that require pressure to build up are not suitableÃ‚Â for marking on hot surfaces.
We regularly manufacture custom built marking machinesÃ‚Â for unique marking applications. If you would like to discuss your requirement regarding hot materials in more detail, please contact usÃ‚Â and we will provide expert advice on your specific application.
