Mold material refers to the specialized steel used in creating various molds, including cold punching dies and hot forging dies. This material forms the backbone of the mold manufacturing industry, a traditional yet continually evolving sector. The diversity, specifications, and quality of mold materials significantly influence mold performance. Recently, the mold industry's output, production technology, and overall quality have seen rapid advancements, bolstered by national support for leading producers like Fushun Special Steel, Great Wall Special Steel, Xingcheng Special Steel, and Hangzhou Steel. The progress in mold manufacturing has driven the creation of more advanced, customized, and high-value industrial products. Mold material finds extensive applications and employs a wide variety of materials, with mold steel being the most prevalently utilized.
Performance Requirements
1. Annealing Processability
The material boasts a broad spheroidizing annealing temperature range, ensuring low and consistently stable annealing hardness, along with a high spheroidization rate.
2. Forgeability
The steel exhibits low resistance to hot forging deformation, excellent plasticity, a wide forging temperature range, minimal tendencies for forging and cold cracks, and reduced precipitation of network carbides.
3. Oxidation and Decarburization Sensitivity
It demonstrates superior oxidation resistance at high temperatures, a slow decarburization rate, and low sensitivity to heating mediums, thus reducing the likelihood of pitting.
4. Cutting Processability
The material allows for significant cutting volumes with minimal tool wear and achieves low surface roughness in machining processes.
5. Hardenability
Post-quenching, the steel can achieve a deep hardened layer and is capable of hardening with mild quenching mediums.
6. Grindability
The steel permits a high limit grinding amount without burning, has a low relative loss of the grinding wheel, and is not sensitive to grinding wheel quality or cooling conditions, thus minimizing the occurrence of grinding cracks and abrasion.
7. Hardenability
After quenching, the steel achieves uniform and high surface hardness.
8. Quenching Deformation Cracking Tendency
The material shows minimal volume change, slight warping, and distortion during conventional quenching, with low sensitivity to quenching temperature and workpiece shape, reducing the risk of abnormal deformation and cracking.
Application
Mold steel plates are crucial in diverse fields, including automotive manufacturing, electronics, home appliances, plastics, and medical devices, where high strength, hardness, wear resistance, and corrosion resistance are paramount.
1. In automotive manufacturing, mold steel plates are indispensable for creating stamping molds, injection molds, and die-casting molds, meeting the rigorous standards of the automotive industry.
2. In electronics, mold steel plates are utilized in molds for mobile phone shells, computer keyboards, and more, requiring excellent processing performance and wear resistance for high precision and stability.
3. In home appliance manufacturing, for molds like those used in refrigerators, washing machines, and air conditioners, mold steel plates must exhibit high hardness, wear resistance, and corrosion resistance.
In plastic products, such as plastic bottle molds, box molds, and pipe molds, the steel plates need outstanding wear and corrosion resistance.
4. In medical device manufacturing, such as molds for surgical instruments, syringes, and artificial joints, the steel plates demand high hardness, wear resistance, and corrosion resistance to meet stringent medical standards.
