Hello Everyone,

I’m working on a project that involves designing molds for high-temperature applications, specifically for thermoplastics that require processing temperatures above 300°C. I’ve been researching materials for the molds themselves and have come across options like tool steels, ceramics, and even some advanced composite materials. However, I’m struggling to determine the best choice based on my specific requirements.

Here are a few details about the project:

• Operating Conditions: The molds need to withstand continuous cycles at high temperatures without significant wear or deformation.

• Precision Requirements: The application requires tight tolerances, so dimensional stability over time is critical.

• Budget Constraints: Cost is always a consideration, but I’m open to more expensive solutions if they provide clear long-term benefits.

• Production Scale: Medium-scale production, so durability is a factor but not at the scale of mass production.

  
  

I’m curious to hear from the community about your experiences with different mold materials in similar scenarios. What has worked well for you, and what challenges have you encountered?

Additionally, I’d appreciate any insights into surface treatments or coatings that could enhance the performance of molds in these conditions. Are there any particular methods that help reduce wear or improve heat resistance without compromising precision?

If anyone has recommendations for suppliers or manufacturers who specialize in such materials, I’d love to hear about those too.

Thanks in advance for your help and support.
