A major client from Guangdong placed an order for 75 pieces of high-toughness\u00a0LG mold steel<\/a> <\/strong>with me, and I\u2019m very pleased.<\/p>\n\n\n\n

 Seeing the 75 pieces of high-toughness LG mold steel<\/strong> ready for shipment in the workshop\u201440 pieces of LG premium material for mold cores and 35 pieces of round bar for insert cores\u2014really put me in a great mood.<\/p>\n\n\n\n

\u00a0He\u2019s a client who makes glass-fiber-reinforced molds, and this time he needs to produce a total of 8\u20139 sets of molds. Previously, the customer didn\u2019t have such high requirements; they typically used H13<\/strong>\u00a0and\u00a0S136<\/a><\/strong>\u00a0for hard molds, quenched and tempered to 50 HRC. However, this time the customer made a special request: the mold must achieve a service life of 3 million cycles. Additionally, the molds feature narrow flanges and small bosses, so the mold design places high demands on the steel\u2019s wear resistance and resistance to chipping.<\/p>\n\n\n\n

 He realized that the materials he had been using were inadequate, so he contacted me a month ago. After several discussions, we ultimately decided to use high-toughness LG <\/strong>mold<\/strong> steel<\/strong>.<\/p>\n\n\n\n

 Originally, he had planned to use high-hardness DC53 to ensure high wear resistance. However, I noticed that the product\u2019s bosses were only 1\u20132 mm wide and relatively tall. Using DC53 for such narrow-edged bosses would likely result in chipping, so I recommended the high-toughness LG mold steel instead.<\/p>\n\n\n\n

 Since LG has 8\u20139 times the toughness of DC53 and a hardness of 54\u201358 HRC, it\u2019s so tough that it won\u2019t break even if you bend it with a hammer. LG excels at molds that require both toughness and wear resistance, especially those with high glass fiber content.<\/p>\n\n\n\n

 I remember when their CEO visited my factory last month; it was pouring rain that day. As the people of Guangdong say, \u201cRain means water, and water means wealth.\u201d I never expected that just half a month later, he would place an order for 75 pieces of high-toughness LG mold steel<\/strong> with me. I\u2019m going to record a video to document this.<\/p>\n\n\n\n

 If your high-glass-fiber-content mold features narrow flanges, has exceptionally high toughness requirements, and needs a service life exceeding 1 million cycles, then I recommend using high-toughness LG mold steel<\/strong>. Its toughness is 8\u20139 times that of DC53, with a hardness of 54\u201358 HRC\u2014it\u2019s so tough that you can bend it with a hammer without it breaking. The high hardness ensures wear resistance, preventing the mold from being worn down and eliminating flash on the product, while the high toughness ensures that even under harsh conditions with narrow flanges, the mold won\u2019t chip or crack. LG mold steel offers both high hardness and high strength, making it a highly suitable choice.<\/p>\n\n\n\n

 I\u2019m Wu Dejian, the \u201cKing of Mold Steel,\u201d from Dongguan Yuhui Mold Steel. Yuhui Mold Steel is used by three Fortune 500 companies, and Kyocera has been sourcing from us for seven consecutive years. If you\u2019re unsure about which mold steel to choose, or if the mold steel you\u2019re currently using results in short mold lifespans and you don\u2019t know which grade to switch to, come talk to me. I\u2019ve helped over 4,000 companies solve complex challenges related to mold material selection, manufacturing, and usage. I\u2019m confident that when it comes to selecting and applying mold steel, I can serve as your chief advisor and help you avoid costly trial-and-error.<\/p>\n\n\n\n
