Mold material is the cornerstone of the mold manufacturing industry, used to craft molds such as cold punching dies and hot forging dies. Its variety, specifications, and quality profoundly impact mold performance. Recently, this sector has seen rapid advancements in output, technology, equipment, and quality, supported by leading enterprises like Fushun Special Steel, Great Wall Special Steel, Xingcheng Special Steel, and Hangzhou Steel. This industry's evolution propels industrial products towards advanced, individualized, and high-value directions. Mold materials, particularly mold steel, are extensively utilized across diverse applications.
Performance Requirements
1. Annealing Processability
Featuring a broad spheroidizing annealing temperature range, it ensures low annealing hardness with minimal fluctuations and a high spheroidization rate.
2. Forgeability
Exhibits low hot forging deformation resistance, excellent plasticity, a wide forging temperature range, and a reduced propensity for forging cracks, cold cracks, and carbide precipitation.
3. Oxidation and Decarburization Sensitivity
Boasts robust oxidation resistance at high temperatures, slow decarburization rate, insensitivity to the heating medium, and a low tendency for pitting formation.
4. Cutting Processability
Enables large cutting amounts with minimal tool wear and produces low surface roughness during machining.
5. Hardenability
Achieves a deep, hardened layer post-quenching and can be effectively hardened using mild quenching media.
6. Grindability
Shows minimal grinding wheel wear, allows for substantial grinding without burning, is insensitive to grinding wheel quality and cooling conditions, and resists abrasion and grinding cracks.
7. Surface Hardness
Post-quenching, it achieves uniform and exceptionally high surface hardness.
8. Quenching Deformation and Cracking Tendency
During conventional quenching, it displays minimal volume change, slight warping and distortion, and a low tendency for abnormal deformation. It also has low cracking sensitivity and is unaffected by quenching temperatures and workpiece shapes.
Application
Mold steel plates are integral to various industries, including automotive, electronics, home appliances, plastics, and medical devices. These sectors demand molds with superior strength, hardness, wear resistance, and corrosion resistance.
1. In automobile manufacturing, mold steel plates are essential for producing stamping, injection, and die-casting molds, meeting the stringent mold requirements of the industry.
2. In electronics manufacturing, such as mobile phone shells and computer keyboards, mold steel plates must exhibit excellent processing performance and wear resistance to ensure product precision and stability.
3. In home appliance manufacturing, including refrigerator, washing machine, and air conditioner molds, these plates need to possess high hardness, wear resistance, and corrosion resistance.
In plastic product manufacturing, for items like plastic bottles, boxes, and pipes, mold steel plates are required to provide exceptional wear and corrosion resistance.
4. In the precision manufacturing of medical devices, such as surgical instrument molds, medical syringe molds, and artificial joint molds, the requirements for mold steel plates are exceptionally high. These applications demand steel sheets with superior hardness, outstanding wear resistance, and unparalleled corrosion resistance to ensure durability and reliability in critical medical functions.
Additionally, there are specialized mold steel plates such as the 1.2343 hot working mold material, a stainless steel renowned for its superb thermoplastic properties. This material is primarily utilized in the fabrication of various hot working molds, particularly in scenarios demanding high-temperature resistance and extended mold longevity. Its exceptional quality makes it a preferred choice for demanding industrial applications.
