“I am continually surprised at how much longer the Alpha coating delays basic sharpening. The attached photos are M4 parts with Alpha coating and they have been in use for over 15 months. My guess is that 15 million parts have been made. They punch thru .057” galvanized steel with a good lubricant. I used to sharpen my uncoated D2 punches every 3 weeks. I have been switching over all die parts from D2 to M4 and then sending for the Alpha coating. When it finally does wear off the M4 immediately shows wear compared to the places the Alpha did not wear off. Those parts are removed – sharpened and sent back to Tincoat and spare coated parts are installed and the die is back in service.
I did have one pair of each (one alpha and one TIN) coated round punches running and the Alpha does have almost no galvanized build-up and the TIN has much more. The machine runs one stroke per second for 8 or 16 hours a day with time down for loading coils and breaks.
To do maintenance, the die has to be removed: 1 hour, I have to separate the die and sharpen punches and re-assemble – the best case would be 2 hrs if only minimum sharpening needed. Die needs about an hour to install and run again. Also, see the reduced chipping of punches. And longer life on the die because the punch stays sharp and therefore less load/wear on the die.
Thanks, Tincoat for reducing my workload and increasing productivity as the dies all run longer without any basic maintenance.”Anonymous Customer
“We ran a full order of 60,000 parts and still don’t need to sharpen. Normally we have to resharpen after 10,000. 6 x more parts than before. The coating far exceeded my expectations.”
It takes 8 hours to remove tools from the press and resharpen them. Saving 6 sharpening saves 48 hours of labor!
