        To ensure temperature control and dimensional consistency, we integrate advanced Systèmes de liquide de refroidissement throughout the machining cycle. Dans de nombreux cas, we also perform post-machining annealing to relieve internal stresses and stabilize the final component. With our specialized tooling and process control, Précision HAUTS can achieve Tolérances extrêmement serrées, making us a trusted partner for aérospatial, électronique, and high-load mechanical applications that demand exceptional accuracy and reliability.

        Why Choose Torlon?

        Torlon excels under extreme mechanical stress, températures élevées, and harsh chemical exposure. Unlike most thermoplastics, it maintains its structural integrity at continuous operating temperatures above 250 °C. À Précision HAUTS, we leverage these exceptional properties to machine high-performance Torlon components for critical applications in the aérospatial, semiconductor, et machines industrielles sectors—where long-term durability and thermal stability are essential.

        Properties of Torlon

        Here are some of the properties of Torlon:

        Properties of Torlon

        1. Service Temperature: Maximum 275°C (527°F)

        Torlon offers one of the highest continuous-use temperatures among thermoplastics, maintaining mechanical strength in environments up to 275°C. À Précision HAUTS, we machine Torlon components for aérospatial, automobile, and industrial systems, ensuring reliable performance in extreme heat conditions where standard plastics would degrade.

        2. Superb Wear Resistance

        Torlon’s outstanding abrasion and friction resistance makes it ideal for dynamic and load-bearing parts such as bagues, roulements, and wear pads. Our precision machining ensures long-lasting dry or low-lubrication performance, even in high-cycle, high-load applications.

        3. High-Grade Creep Strength

        Torlon’s low creep behavior allows it to maintain dimensional accuracy under prolonged mechanical stress and elevated temperatures. Précision HAUTS machines Torlon for long-term structural parts dans aerospace and high-stress mechanical assemblies, where deformation cannot be tolerated.

        4. Résistance chimique

        With resistance to aggressive chemicals, acides, carburants, hydraulic fluids, et solvants, Torlon is perfect for fluid-handling systems, équipement de traitement chimique, et automotive underhood parts. We ensure each machined part at Précision HAUTS meets the chemical exposure demands of your application.

        5. Low Thermal Expansion

        Torlon’s very low coefficient of thermal expansion allows us to machine parts with tight tolerances that remain consistent across a wide temperature range. This thermal stability is essential for precision gears, logements, and other parts where précision dimensionnelle is critical.

        6. Strengths due to High Tension and Flexure

        Torlon delivers mechanical strength comparable to some metals, offering excellent resistance to stress, choc, and vibration. À Précision HAUTS, we produce structural components that can withstand impact and high-load conditions without cracking, making it an ideal material for demanding mechanical environments.

          Design Recommendations for Torlon Parts

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

          1. No Sharp internal Angles

          À Précision HAUTS, 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 plus fort, more reliable component.

          2. Add Thread Radii

          When designing threaded features, incorporation rounded roots or small radii improves Resistance à la fatigue and machining efficiency. This approach allows our team to use more accessible tooling, résultant en 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. À Précision HAUTS, 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

          Pour des résultats optimaux, avoid extremely thin or overly thick walls. À Précision HAUTS, we recommend maintaining uniform wall thicknesses to balance force, material efficiency, et usinabilité. This helps reduce warping, improves thermal consistency, and minimizes material waste.
