Choosing the Right Mold Steel Material for Custom Silicone Products: 55# vs P20 vs 718 vs S136
When it comes to custom silicone products, choosing the right steel material for molds is crucial. For low production quantities with less strict requirements, 55# high-carbon steel can be used. However, for high production quantities with long lead times and strict surface finish requirements, P20, 718, and S136 steel materials are recommended.
When to choose 55# steel for custom silicone products?
- When the structure of the custom silicone product is relatively simple, and the product quantity is low.
- When the sample mold is used to test product assembly structures.
- When cost control is essential, 55# steel can be chosen in either of the above situations as it is affordable and easy to process.
When to choose P20, 718, and S136 steel for custom silicone products?
- When the silicone product has strict size requirements.
- When the silicone surface requires special finishes, such as high transparency or a mirror finish, or when the mold surface requires polishing or electroplating processes.
- When the product requires high-quality molds for large-scale production with strict product alignment requirements.
- In general, if the number of customized products is small, 55# steel is recommended as it has low material and processing costs, allowing for minimal development expenses.
If you are considering mass-producing silicone products, P20 mold steel is a good choice. It has a moderate price and good wear resistance, making it suitable for manufacturing high-precision silicone parts. At the same time, it has good cutting performance, making it suitable for precision machining. This steel material is suitable for large-scale production and can maintain stable product quality.
TOGOHK has the ability to produce silicone products with high precision and strict mold line requirements. Choosing 718 mold steel would be an excellent option for this. This type of steel has high hardness and strength, which can be used to manufacture high-quality molds and ensure product accuracy and consistency. Additionally, 718 mold steel has high wear and corrosion resistance, which allows it to maintain mold accuracy under high-temperature and high-pressure conditions. This type of steel can also be processed through methods such as machining and EDM to ensure high precision and surface quality of the mold.
If you need to produce large quantities of stable and highly precise silicone products, choosing S316 mold steel is a great option. This type of steel has high corrosion resistance and heat resistance, which helps maintain the precision and stability of the mold in high-temperature and high-pressure situations. If you need to engage in 24-hour large-scale production, S316 mold steel can help you control product size and quality, ensuring high efficiency and productivity.
