Impact Markers handle marking pressures to 12 tons.
Press Release Summary:
Double-acting, air-operated Slide-A-Mark models 651 and 851 utilize same cylinder body and bolt-mounting pattern and are offered with various keyed air-powered rod and stamp holder styles. Model 651 produces force range of ¼-6 tons, while Model 851 produces force range of 1½-12 tons. Markers utilize 2-stage impact marking sequence and fixed internal air passages that control speed. Strokes range from 2½-12 in., and marking pressure remains same anywhere within stroke.
Original Press Release:
Columbia Marking Tools Introduces Two New Slide-A-Mark Double Acting Impact Markers to Expand their Range of Marking Capability
651 & 851 Slide-A-Mark models now handle marking pressures to 6 tons and 12 tons respectively
Columbia Marking Tools, Inc. pioneered the development of the double-acting air-operated impact marker and for many years the model 751 Slide-A-Mark eight-ton unit has been the preferred choice for applying impact marks in a wide variety of materials. This includes such things a date & shift codes, QC marks, part numbers, traceability marks, company logos, lot numbers, trademarks and even some staking operations.
As industry continues to increase traceability and the number of marked characters while utilizing new types of alloys, steels and different formulations of casting materials, more versatility in the range of marking pressure capability has been needed. For these reasons, Columbia Marking Tools has added two additional standard Slide-A-Mark impact marker models to provide the user with added capability.
The new units, Model 651 and 851, are similar in design and function. Each model utilizes the same cylinder body and bolt-mounting pattern to enhance interchangeability. A variety of different keyed air-powered rod and stamp holder styles are available. The Model 651 can produce a force range of 1/4 to 6 tons, the Model 851 a force range of 1-1/2 to 12 tons. In operation, the markers utilize a two-stage impact marking sequence where the marker telescopes out to pre load the stamp or staking tool against the work piece and then the cylinder fires an internal hammer generating a consistent impact force which is varied by controlling the actuation air pressure. Fixed internal air passages control the marker's speed. (Typically a 2-1/2-inch unit cycle is less than one second).
Each model is offered with optional retracted or dual position sensors for return and advanced position of the cylinder stroke to augment their application with automation. By simply loosening a mini dovetail clamp, the advance position sensor can be adjusted to one inch. Strokes can range from 2-1/2 to 12-inches while the marking pressure remains the same anywhere within the stroke.
Slide-A-Marks are powered by factory air and controlled by a standard 4-way air valve with a regulator to vary the marking force. It is recommended the mail shop supply to be a ½-inch air line with a maximum pressure of 100 psi.
Columbia Marking Tools is a leading designer and manufacturer of metal and plastic marking equipment including stamps, roll marking dies, roll marking and impact marking machines, fully-programmable peen marking machines, numbering heads and special marking machines.
