Every week, Team Protocase is bringing you a Proto Tech Tip video, where we’ll give an informative look at a particular aspect of sheet metal fabrication and CNC Machining.

This week, we’ve got Cody from our Engineering & Design Services team reviewing the different ways we can achieve permanent marking here at Protocase.

Watch the full video below – or, if you’d prefer to read his Proto Tech Tip, we’ve got the full transcription below the video.

Hey everyone, Cody here from Protocase with another Proto Tech Tip. Today we’re going to talk about part marking. We offer a number of different types of part marking here at Protocase. The processes we use are rubber stamping, dot peening, a simple avery label, or silkscreen ordigital printing.

Part marking is permanently labeling or marking your enclosures with numbers or letter combinations. It’s especially useful for serialization and traceability.

Dot peening is done by a machine that actually indents the metal to create letters or numbers that are easily recognizable. This process can be done before powdercoat or after powdercoat. Both allow for good visibility.

Rubber-stamping is done by creating letter and number combinations and then applied using permanent ink. These can be applied with either black or white ink, depending on the finish of your enclosure.

Avery labels can have any type of text that you want as they are printed out on these labels using a standard printer and then applied to your part or to the outer most packaging of your part.

As well, we do offer another form of parking via machined engraving using our CNC machines. All of these processes offer different ways for you to permanently mark your part or enclosure.

However keep in mind that we can also apply these part markings by way of silkscreen or digital print.

If you would like some part marking applied to your part or enclosure, please let us know and we can recommend a process to use. Feel free to check out our website for more information regarding part marking.

We’ve put some direct links in the description below. Be sure to also check out our blog, which outlines many other technical tips or just send us an email at info@protocase.com.

Thanks for watching this week’s Proto Tech Tip. I hope you found it helpful and be sure to check us out next week for another one.
