Cold-extruded T2 red copper (8566) not only solved the problem of punch breakage but also increased punch lifespan by more than 10 times\u2014this was the most valuable comment in the 295th live stream.<\/p>\n\n\n\n

\u00a0A long-time customer commented in the livestream that 8566 cold-stamped red copper works very well. They\u2019ve made one punch so far, and it hasn\u2019t broken yet\u2014though the heat treatment is a bit of a hassle. A 16-gauge punch is stamping to a depth of 20, and they\u2019ve stamped over 10,000 pieces so far using T2 copper on a standard press. We\u2019ve tested many materials for stamping red copper; previously, we used DC53<\/a><\/strong>, which would break easily after just a few hundred stamps, and we\u2019ve also tried Cr12MoV.<\/p>\n\n\n\n

 Based on feedback, the service life of 8566 punches used to break after just a few hundred strokes, but it has now been extended to over 10,000 strokes without breaking\u2014a more than 10-fold increase in service life.<\/p>\n\n\n\n

 When you look at it this way, the difference between the old and new situations is like night and day.<\/p>\n\n\n\n

 The service life of 8566 punches is more than 10 times that of DC53\u2014a 10-fold increase\u2014but the price of 8566 is not 10 times that of DC53, which highlights its price advantage.<\/p>\n\n\n\n

With a 10-fold increase in service life, one 8566 punch is equivalent to 10 DC53 punches. This saves the machining costs of 10 punches, effectively making the 8566 punch free to use, while the reduced need to replace 10 punches further boosts efficiency.<\/p>\n\n\n\n

 Receiving the 8566 also helped the customer resolve the punch breakage issue, while extending service life by more than 10 times. It enabled the customer to achieve high efficiency, long service life, and low costs\u2014which makes me very happy.<\/p>\n\n\n\n

\u00a0Using 8566 die steel<\/a><\/strong>\u00a0to address punch breakage\u2014it\u2019s like night and day compared to the old solution\u2014and this has once again been perfectly demonstrated.<\/p>\n\n\n\n

 It feels great to be live-streaming while enjoying praise from customers!<\/p>\n\n\n\n
