I\u2019m pretty happy to hear the good news that the 8566 has increased mold life by 10 times.<\/p>\n\n\n\n
Mr. Li said, \u201cThe last time I bought a piece of your 8566, it worked really well.\u201d<\/p>\n\n\n\n
I asked him, \u201cHow many products can the current 8566 stamp in one go?\u201d<\/p>\n\n\n\n
He replied, \u201cThe service life has increased 10-fold.\u201d<\/p>\n\n\n\n
Mr. Li\u2019s mold is made of 4.0 hot-rolled steel plate, formed into blocks. Currently, he uses fourth-grade 8566 at 109 yuan per kilogram, and after 10,000 stamping cycles, the cutting edge chips and cracks.<\/p>\n\n\n\n
Based on the 10-fold increase in service life Mr. Li mentioned, the current Yuhui 8566 should be able to withstand 100,000 stamping cycles.<\/p>\n\n\n\n
It isn\u2019t 10 times more expensive than the 109 yuan\/kg \u201cfour-recycled\u201d 8566, yet the die life is 10 times longer. When compared this way, the cheaper \u201cfour-recycled\u201d 8566 actually ends up being the more expensive option.<\/p>\n\n\n\n
Although we often receive positive feedback from customers, every time I hear it, I feel an inexplicable sense of joy and an urge to say a few words.<\/p>\n\n\n\n
\u00a0When it comes to punch chipping, using 8566 die steel<\/a><\/strong>\u00a0makes all the difference\u2014it\u2019s like night and day\u2014but the fourth-grade 8566 doesn\u2019t deliver the same results.<\/p>\n\n\n\n *************<\/p>\n\n\n\n<\/figure>\n\n\n\n
