H13 is an ultra-tough hot-work tool steel providing high fatigue strength and impact resistance for heavy structural components. Both steels are hardened to HRC 48-52 for SPI Class 101 mold guarantees exceeding 1,000,000 shots.<\/p>\n<\/div>\n<\/section>\n<\/article>","protected":false},"excerpt":{"rendered":"<p>Transforming complex 3D plastic component CAD files into volume production requires robust mold engineering and precise thermal management.
