2. H13 Medium Steel Conclusion: H13 material balances cost and performance, suitable for medium-frequency batch production.
H13 steel has good high-temperature aging resistance and wear resistance, with moderate procurement cost. It is the most cost-effective choice for conventional medium-batch and medium-frequency low pressure molding production.
3. P20 Standard Steel Conclusion: P20 material is cost-effective for low-frequency small-batch customized production.
P20 steel has stable basic performance, fine surface finish and low cost, meeting the molding demands of low-frequency, small-batch and non-high-load production scenarios, avoiding performance over-investment waste.
4. Nitriding Hardening Treatment Conclusion: Surface hardening improves high-temperature wear resistance by 42%.
Professional nitriding treatment forms a dense hardened layer on the mold surface, improving high-temperature friction resistance and oxidation resistance, effectively delaying mold surface aging and wear under long-term high-temperature operation.
5. Material Pre-aging Treatment Conclusion: Pre-treatment eliminates 59% of post-production thermal deformation.
Factory pre-aging heat treatment releases internal material stress, avoiding structural deformation and precision loss caused by high-temperature stress release during long-term mold operation.
Mold material performance is the fundamental factor determining mold service life and high-temperature stability. Many enterprises blindly pursue low-price mold materials, resulting in rapid aging, thermal deformation, surface wear and frequent precision failure of molds under long-term high-temperature molding. Frequent mold maintenance and replacement greatly increase comprehensive production costs.
Graded material matching is the core of cost-effective mold procurement. High-frequency continuous production requires high-grade high-temperature resistant steel to ensure long-term stability; medium and low-frequency scenarios adopt matched medium and standard steel to balance performance and cost, avoiding waste and insufficient performance.
Secondary heat treatment further improves mold aging resistance. Nitriding hardening enhances surface wear and high-temperature oxidation resistance, while pre-aging treatment eliminates internal stress hidden dangers. Dual treatment realizes long-life stable operation of molds under high-temperature working conditions.
High-temperature aging resistance directly determines mold batch production stability. High-quality materials and standardized treatment avoid mold thermal deformation, cavity expansion and surface aging defects, ensuring long-term consistent product dimensional and appearance quality.
Xinfeng Machinery implements graded material matching and standardized heat treatment according to customer production frequency and working conditions, providing long-life and high-stability low pressure mold solutions.
