1. P20 steel
P20 steel, also known as 3Cr2Mo steel, is a low-alloy heat-resistant steel and is widely used in mold manufacturing. It is characterized by good toughness, excellent processing performance, moderate hardness and long service life. P20 steel is suitable for making flat molds, complex molds and injection molds, etc.
2. NAK80 steel
NAK80 steel is a high-quality optimized steel produced in Japan. Its hardness and wear resistance are higher than P20 steel. NAK80 steel has excellent dimensional stability and corrosion resistance, and is suitable for making high-precision, high-quality molds, such as mobile phone casings, lenses and other small household appliance molds.
3. S136 steel
S136 steel, also known as 420 steel, is a high-quality stainless steel that is widely used in the field of mold manufacturing. S136 steel has excellent corrosion resistance and processing performance, high hardness, wear resistance, and impact resistance. It is suitable for making high-quality, high-precision, and durable small household appliance molds.
4. H13 steel
H13 steel is a commonly used type of hot tool steel. It is characterized by extremely high hardness and wear resistance, and is not easy to deform and crack. H13 steel is suitable for making high-temperature and high-pressure molds, hot stamping molds, die-casting molds, etc.
Among them, S136 steel and H13 steel are two widely used steel materials. Both steels have excellent corrosion resistance and high temperature performance, but they are relatively expensive to build. The following will introduce the characteristics of these two steel materials and their application in small household appliance mold manufacturing.
S136 steel is a kind of steel with high purity, high wear resistance and high hardenability. It has good processing performance and polishing performance, and is widely used in the manufacture of high-precision and high-demand molds such as medical devices, electronic parts, and optical instruments. In the manufacturing of small household appliance molds, S136 steel is often used to make molds with high appearance requirements, such as coffee machines, rice cookers, juicers, etc.
H13 steel is a steel with high toughness and high corrosion resistance. It has good thermal fatigue resistance and corrosion resistance, and is suitable for manufacturing high-strength, high-corrosion-resistant molds such as die-casting molds, extrusion molds, and plastic molds. In the manufacturing of small household appliance molds, H13 steel is often used to manufacture molds with complex structures and large stresses, such as air conditioner outdoor unit shell molds, washing machine shell molds, etc.
Due to the high cost of S136 steel and H13 steel, other economical steel materials are usually chosen for manufacturing some price-sensitive home appliances. For example, No. 45 steel is a relatively affordable steel. It has good processing performance and strength, and is suitable for manufacturing molds with simple structures and low stress. In addition, some economical plastic mold steels such as NAK80 2738H 718H are also widely used in small household appliance mold manufacturing.
Overall, choosing the right steel is crucial for small appliance mold manufacturing. It is necessary to comprehensively consider factors such as product appearance requirements, structural complexity, stress conditions, etc. to select the most appropriate steel for manufacturing. At the same time, the selection of some economical steel materials also needs to be weighed and made based on actual conditions.
