COLUMBIA MARKING TOOLS EXPANDS BOTTLE MARKING LINE TO INCLUDE BOTH ROLL AND PEEN MARKING TECHNOLOGIES

Peen marking adds new technology to accommodate thin walled and lighter weight type commercial bottles.

For over twenty years, Columbia Marking Tools has been designing and building special production roll marking machines for commercial metal bottles and cylinders that range from 14 to 81-inches in length and from 3 to 8-1/2-inches in diameter. These heavy-duty machines are able to mark up to 55 characters per line in either a 1/4 or 5/16-inch character size. Cycle times are typically from 7 to 20 seconds, depending on the number of characters to be marked.
The basic design of the roll marking machine features a horizontal wing base that mounts the hydraulic roller details that trap the bottle between a back-up and the hydraulic marking head. Proper positioning is determined by locating off the conical nose end of the bottle. When properly located, the roll marker contacts the bottle surface and begins the roll marking process to the predetermined length of the mark. Hydraulic marking pressure settings are determined by the character size and depth of mark. The key to achieving a uniform, legible mark on this type of a curved surface is the utilization of a roll marker that has two sets of the same mark in different holders in the marker roll. The marks are at different angles. When the roll completes the first pass, it rolls back at the second angle to finish the mark.
Now, Columbia Marking Tools  programmable peen marking technology to the same type of bottle marking machine design giving them more capability for bottles and cylinders with thinner walls and softer materials.

260 Roll Marking Machine

Project scope:  CMT to supply two model 260 Roll Marking Machines. Customer to supply part fixturing. Marking legend is typically 6-8 (1/8″) characters and the Customers Logo, estimated marking time is 3 seconds.  Parts are threading inserts that will be marked on the flat top side of the parts.

Note:  machine to have CUSTOM BASE with height of 38″ from floor to part fixture mounting surface. Also to have CUSTOM PALM BUTTON arrangement with horizontal mounting of buttons to column (not base), these buttons are to have special LOW PRESSURE push settings.

3 different part fixture drawings were provided to CMT:
–  EJ727 sheet #5 is a riser plate of some kind with a height of 3.125 inches
–  EJ727 sheet #4 is an adapter plate of some kind with a height of .750 inches
–  J23867 sheets #1-#6 are insert holder fixtures that range in height from 1.0 inches to 2.2 inches with a mean height of 1.6 inches.

Based on the provided drawings CMT will use the combined height of all three part fixture details of 5.4″ from our table mount surface to achieve the 38″ height from floor as stipulated in the above note. CMT will send approval drawing for customer signoff showing this height, signing the drawings means that you have approved this fixture stackup calculation as being correct or representative of the typical fixture height that you will use.
