Roller dies are a simple and easy solution for marking repetitive information on moving products. They use less force than other indenting methods because only a fraction of the message is being indented at one time as the die rolls along the material. They are suitable for marking of a wide variety of products such as:
- bar, tube, conduit, and hose
- wire and cable
- extruded building materials
- soft materials such as plastic, rubber, clay, and leather
Roller dies can be mounted on a shaft for continuous marking of moving materials or mounted in a roll marking machine, lathe, or screw machine for marking individual parts.
Options
- flat characters for marking flat materials
- concave characters for marking tubing and other round materials
- made of tool steel for marking materials up to 30 HRC hardness
- optional high speed tool steel for marking materials up to 34 HRC
- made with or without a keyway for mounting on a keyed shaft
For applications where the message does not change, an engraved roller die can be made with text or logos engraved in any character size or depth so you can achieve your desired mark. Dies are manufactured with high quality tool steel and heat treated for excellent performance and longevity.
Sandwich Style Holders
Interchangeable characters and segments are held by a removable clamping plate. Good for marking applications where messages change, such as date coding and lot coding.
Mortised Style
Fitted with interchangeable wedge-shaped dies that are held in place by set screws. Extra legend inserts can be ordered to fit in each mortice.
Choosing a Die Size
To determine the size of roll marking die for your needs, the following questions must be considered:
- What is the desired height of the characters in the message?
- How long is the complete message that needs to be marked (how many characters)?
- How often should the message repeat? Every 6″, every 18″, etc?
In this illustration, two different size dies are engraved with an identical message in the same character size.
The smaller die has a circumference of 6″, which means the message will be marked on the product every 6″, while the larger 18″ circumference die will place a mark every 18″.
If the product being marked is not on a conveyor and has no support at the point where it will be marked, a backup roll will be required to support and apply pressure to the opposite side of the product.
The roll can be a flat roll to support flat products or a concave roll to support round products such as pipe or wire to prevent deformation. Pannier can manufacture concave backup rolls to the same specifications as the roll marking dies to make installation easy.
Roll marking dies are mounted on a shaft above the product being marked. The friction of the product moving underneath the die causes it to turn at the same speed as the product. Dies are usually supplied with a keyway for mounting on a keyed shaft.
All roll dies and holders are designed and manufactured to your exact specifications.
Information Required for Quotation
- Desired message or artwork
- Character size and style
- The number and spacing of message repeats, if applicable
- Desired size of bore (mounting hole)
- Whether a keyway is desired and size (3/8″ wide standard) to keep the roller die in place on a keyed shaft
- Details on the material being marked: type of material, dimensions, hardness, temperature, line speed, etc.
- Desired depth of mark in your material
- Mounting information: top or bottom of line, whether or not a back-up roll is required
