Product Selection Differences for Plastic Moulding Tool Steel

When selecting Plastic Moulding Tool Steel, there are several key factors to consider, including:

1. Hardness: The hardness of the steel will affect its wear resistance and ability to maintain its shape during high-pressure molding processes.

2. Wear Resistance: Look for steel grades with high wear resistance to prolong tool life and reduce the frequency of tool maintenance or replacement.

3. Toughness: Toughness is essential to prevent tool failure due to cracking or chipping, especially in high-impact applications.

4. Corrosion Resistance: Some plastic materials may be corrosive to certain steel types. Choosing a steel with good corrosion resistance can help prolong the tool's lifespan.

5. Polishability: For injection molding applications that require smooth surface finishes, selecting a steel that is easily polishable is essential.

6. Thermal Conductivity: Higher thermal conductivity can help in achieving faster cooling times and more consistent molding results.

7. Cost: Consider the overall cost, including the initial material cost, machining costs, and potential savings in tool maintenance and replacement.

Some popular types of tool steel used in plastic molding applications include P20, H13, S7, and 420 stainless steel. Each steel type offers a unique combination of properties suited for different molding processes and materials. It's essential to consult with material suppliers, tooling experts, and consider the specific requirements of your molding project before making a selection.
