Before diving into the comparison, it’s essential to grasp what plastic mold steel entails. These steels are specifically designed to withstand the rigors of molding processes. They possess unique properties that enable them to endure heat, mechanical stress, and various corrosive elements produced during manufacturing.
P20 steel is a versatile and widely-used plastic mold steel. Renowned for its excellent machinability and uniform hardness, it is often the go-to choice for a variety of applications.
Due to its exceptional characteristics, P20 is widely used in applications like:
S7 steel, on the other hand, is a tool steel known for its outstanding impact resistance. While it is not as commonly used as P20 for plastic molds, it has its own unique benefits that may be advantageous in specific settings.
S7’s unique attributes make it suitable for:

The question of which steel is superior boils down to the specific requirements of your project. Here are some key aspects to consider:
If easy machining and intricate designs are your primary focus, P20 takes the lead. Its superior workability simplifies production processes, making it a favorite among mold makers.
For applications where molds are subjected to high levels of stress, S7 is the better choice due to its high impact resistance. This characteristic allows it to withstand sudden loads and extreme conditions.
P20 is generally more accessible and usually costs less compared to S7. If budget constraints are a consideration, P20 could be the more feasible option.
Ultimately, the choice between P20 and S7 will heavily rely on the intended application. For standard plastic injection molds, P20 is often preferred. However, if the design entails rugged usage or high impact, S7 becomes invaluable.
In summary, the selection between P20 and S7 steel for plastic molds depends primarily on your project’s specific needs. P20 offers exceptional machinability and uniform hardness, making it a go-to for typical applications. In contrast, S7 shines in scenarios where impact resistance is critical. Understanding their distinct characteristics will help you make an informed decision, ensuring the longevity and efficiency of your molds. Whatever your selection, both steels provide reliable options for the diverse world of plastic mold manufacturing.
