Conclusion: Forging forming improves mold steel structural density. Data: Steel compactness increases by 18% compared with rolled steel. Explanation: Multi-directional forging eliminates internal loose structures and tiny voids.

Conclusion: Graded forging specs match different mold types. Data: 8T forging fits large wheel hub mold blanks 100%. Explanation: Matching forging tonnage avoids uneven material fiber distribution.

Conclusion: ESR process enhances steel high-temperature resistance. Data: Thermal deformation resistance improves by 29% at 650℃. Explanation: Purified structure maintains stable hardness under continuous high temperature.

Conclusion: Qualified forging reduces mold later failure rate. Data: Material-induced mold failure drops from 12% to 3.5%. Explanation: Uniform forging texture avoids local stress concentration damage.

Mold steel forging process is the source core of casting mold quality, and the purity and structural uniformity of raw steel directly determine the service life, precision stability and defect resistance of finished molds. Most low-quality casting mold failures in the industry are caused by unqualified raw steel forging, including excessive impurities, loose internal structure and uneven hardness distribution. Yongfeng Mold Group supports Zhejiang Xinfeng Machinery with complete independent forging production lines, covering 8T, 5T, 4T, 3T and 1T forging equipment and ESR electroslag remelting technology, realizing full self-production of mold raw materials and ensuring stable mold quality.

ESR electroslag remelting is the key process to improve mold steel purity. Ordinary industrial mold steel has a non-metallic impurity content of more than 0.08%, which will form tiny defect points inside the steel. Under long-term high-temperature and high-pressure casting working conditions, these defect points will expand gradually, causing mold cracking and wear. After ESR remelting purification, the impurity content of H13 and 35CrMo mold steel drops by 41%, eliminating microscopic defect sources from the raw material end and greatly improving the structural stability of the mold.

Multi-stage forging forming optimizes the internal structure of mold steel. Compared with ordinary rolled steel, forged steel has 18% higher compactness, and the internal metal fiber structure is continuous and uniform, without loose voids. Different tonnage forging equipment is matched according to mold blank specifications: 8T large forging equipment is fully applicable to large integral wheel hub mold blanks, avoiding uneven fiber distribution and local hardness difference caused by mismatched forging force. This targeted forging matching process ensures 100% structural uniformity of mold blanks.

Purified and forged mold steel has excellent high-temperature performance, which is the core demand of casting mold working conditions. At a high temperature of 650℃ for long-term casting, ESR forged steel has 29% higher thermal deformation resistance than ordinary steel, maintaining stable 48-52HRC hardness without softening or deformation. Industry data shows that molds made of non-ESR forged steel have a 12% material-induced failure rate, while qualified ESR forged molds reduce this index to 3.5%, greatly reducing later maintenance and replacement costs for casting enterprises.
