• Applications: This process is commonly used in producing stents, where precise and intricate cuts are necessary for flexibility and structural integrity.

3. Annealing

Annealing is a heat treatment process used to improve the ductility and flexibility of the hypotube material. After tube drawing, the metal may become work-hardened and brittle. Annealing involves heating the hypotube to a specific temperature and then gradually cooling it to relieve internal stresses and improve its ability to bend without breaking.

• Improved Flexibility: Annealing is particularly important for superelastic materials like Nitinol, which are used in devices that need to conform to complex anatomical pathways.
• Enhanced Strength: For stainless steel and other alloys, annealing helps improve mechanical properties while retaining the tube’s strength.

4. Coating and Surface Treatments

Coating and surface treatments are applied to improve the hypotube’s performance and durability. Common coatings include PTFE (polytetrafluoroethylene) and silicone, which reduce surface friction and improve biocompatibility, making it easier to insert the tube in medical devices.

• Friction Reduction: Coatings help reduce friction, improving the performance of devices such as catheters that need to be inserted into the body smoothly.
• Corrosion Resistance: Coatings can also improve the hypotube’s resistance to corrosion and chemical exposure, which is especially important in industrial environments.

5. Electrochemical Grinding (ECG)

Electrochemical grinding is used to achieve fine finishes and ensure the tube’s dimensions are precise. This process combines electrochemical and abrasive grinding techniques to remove material with minimal mechanical force. ECG is particularly useful for sharpening or polishing the ends of hypotubes or adding specific geometric features.

• Minimal Thermal Damage: Unlike traditional grinding, ECG minimizes the risk of thermal damage, which can be critical for maintaining the tube’s properties.
• Smooth Finishing: This process ensures that the hypotube has a smooth surface, which is essential for applications where friction needs to be minimized.

6. Micro-Forming

Micro-forming techniques are used to bend, crimp, or shape hypotubes into specific configurations. These processes are highly controlled to ensure that the small, delicate hypotubes maintain their structural integrity even after being shaped.
