          Design Recommendations for Torlon Parts

          Here are some of the important design recommendations for Torlon machining:

          1. No Sharp internal Angles

          A Tops Precision, we recommend filleting all internal corners instead of using sharp angles, which tend to create internal stress concentrations. Rounded features not only enhance part durability but also minimize the risk of cracking during machining or end use—ensuring a più forte, more reliable component.

          2. Add Thread Radii

          When designing threaded features, incorporazione rounded roots or small radii improves resistenza alla fatica and machining efficiency. This approach allows our team to use more accessible tooling, con il risultato di cleaner threads and reduced tool wear—especially critical for high-strength or precision-threaded parts.

          3. Creep and Expansion

          Although Torlon has low creep and thermal expansion, these factors must be considered for high-temperature or long-term applications. A Tops Precision, we assist clients in specifying the correct tolerances during the design phase to ensure dimensional stability under thermal and mechanical stress.

          4. Consider shrinkage after machining.

          Torlon components often undergo post-machining treatments like annealing, which may cause minor dimensional changes. Our engineers work with clients to anticipate and compensate for shrinkage in tight-tolerance or interlocking parts—ensuring accuracy from design to final product.

          5. Minimize Wall Thickness

          Per risultati ottimali, avoid extremely thin or overly thick walls. A Tops Precision, we recommend maintaining uniform wall thicknesses to balance forza, Efficienza materiale, E lavorabilità. This helps reduce warping, improves thermal consistency, and minimizes material waste.
