When it comes to die stamping, friction generates heat. Heat can be a big cause in slowing production and decreasing tool life.
A reel manufacturer was seeing the effects of the heat in their process. They had a stamping machine that was creating sprocket holes in the outer edge of a 35mm film. These holes are used for advancing the reel strip through printers, projectors, and processing machines. They had to be particularly careful, as film materials warp easily with heat. Some of us remember the film reels that would bubble and burn out when the film stopped in the projector. (I am giving away my age a bit). So, speed was critical as they did not want to create any quality issues.
They were intrigued with the EXAIR Vortex Tubes as it can generate cold air by only using compressed air. Vortex Tubes do not use refrigerants or have any moving parts. They are very compact and can fit into tight places. If they could reduce the temperature in the stamping process, then they could speed up production.
With the Vortex Tubes, EXAIR adds accessories to help with installations for different applications. For this customer, the Cold Gun Aircoolant System was the best product to deliver the cold air. I recommended the model 5315 Cold Gun System. This product generates 1000 BTU/hr of cooling power, and it has a Dual Point Hose Kit to target both sides of the film reel. It includes a magnetic base to securely position it on the stamping machine, and two 1” flat nozzle ends to attach at the end of the Dual Point Hose Kit. These flat nozzles would help to direct the cold air in between the two stamping plates. They were able to keep the film reel and the die stamp cool as they sped up their operation. Even with the additional speed, they also noticed that the die stayed sharper 20% longer before they had to rework.
If you believe that heat is slowing down your system, EXAIR may have a product to keep it cool. With the customer above, heat was a “reel” problem. With the Cold Gun System, we were able to increase their productivity and decrease their downtime. You can contact an Application Engineer to discuss your application if you believe that temperature is affecting your process.
