Product Selection Differences for Diamond Knurled Press or Heat Fit Inserts, Thermoplastic Applications

When choosing between Diamond Knurled Press and Heat Fit Inserts for thermoplastic applications, there are several key differences to consider:

  1. Installation Method:

    • Diamond Knurled Press Inserts: These are typically installed by pressing them into the pre-drilled hole in the thermoplastic material. The knurls on the insert provide resistance to rotation and pull-out.
    • Heat Fit Inserts: These inserts are installed by heating them up and then pressing them into the thermoplastic material. As they cool and shrink, they create a secure interference fit.
  2. Strength and Pull-Out Resistance:

    • Diamond Knurled Press Inserts: These inserts rely on the knurled design to provide resistance to pull-out forces. They are suitable for applications with moderate to high torque loads.
    • Heat Fit Inserts: Heat fit inserts create a strong mechanical bond with the thermoplastic material due to the interference fit. They are ideal for applications where high pull-out resistance is required.
  3. Installation Equipment:

    • Diamond Knurled Press Inserts: These inserts can be installed using simple press-fit tools that do not require heating equipment.
    • Heat Fit Inserts: Installing heat fit inserts requires the use of a heating tool to heat the insert before insertion, which adds to the complexity of the installation process.
  4. Material Compatibility:

    • Diamond Knurled Press Inserts: These inserts are suitable for a wide range of thermoplastic materials, but may not be as effective in materials with high hardness or low thermal conductivity.
    • Heat Fit Inserts: Heat fit inserts can be used in a variety of thermoplastic materials, including those with high hardness or low thermal conductivity, as the heat helps to soften the material for insertion.
  5. Cost and Efficiency:

    • Diamond Knurled Press Inserts: These inserts are generally more cost-effective and easier to install compared to heat fit inserts, making them a popular choice for many applications.
    • Heat Fit Inserts: While heat fit inserts may be more costly and require additional equipment for installation, they offer a high level of pull-out resistance and reliability in demanding applications.

By considering these factors, you can determine the best option for your specific thermoplastic application based on the required strength, installation method, material compatibility, and budget constraints.
