Product Selection Differences for Plastic Mould Steel

When selecting Plastic Mould Steel, there are several key factors to consider that can impact the performance and longevity of the molds. Here are some key differences to consider:

1. Steel Grade: Different grades of steel have varying properties such as hardness, toughness, and corrosion resistance. Common grades for plastic mold applications include P20, H13, S136, and 420SS. Each grade is suitable for different types of molding applications.

2. Hardness: The hardness of the steel is an important factor to consider, as it affects the wear resistance and durability of the mold. Higher hardness is generally desirable for molds that will be used with abrasive materials or for high-volume production.

3. Toughness: Toughness is crucial for withstanding impact and preventing cracking or chipping during the molding process. It is particularly important for molds that will undergo high-stress conditions.

4. Corrosion Resistance: Corrosion resistance is key to preventing rust and maintaining the quality of the mold over time. This is especially important if the mold will be exposed to moisture or corrosive materials.

5. Machinability: The machinability of the steel can impact the ease of manufacturing and maintaining the mold. Better machinability can result in faster production and reduced costs.

6. Polishing Properties: Some molds require a high degree of polishing for the final product finish. The steel selected should have good polishing properties to achieve the desired surface quality.

7. Cost: The cost of the steel is an important consideration, as it can vary based on the grade and quality of the material. Balancing performance requirements with budget constraints is crucial.

It is recommended to consult with a materials engineer or a specialist in mold making to determine the most suitable Plastic Mould Steel for your specific application and requirements.
