Design Recommendations for Torlon Parts
Here are some of the important design recommendations for Torlon machining:
1. No Sharp internal Angles
で TOPSプレシジョン, 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 より強い, more reliable component.
2. Add Thread Radii
When designing threaded features, 組み込む rounded roots or small radii improves 疲労耐性 and machining efficiency. This approach allows our team to use more accessible tooling, その結果 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. で TOPSプレシジョン, 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
For optimal results, avoid extremely thin or overly thick walls. で TOPSプレシジョン, we recommend maintaining uniform wall thicknesses to balance 強さ, material efficiency, そして 被削性. This helps reduce warping, improves thermal consistency, and minimizes material waste.
