Key Capabilities
- TPU with tungsten powder and other modified materials can be processed for specialized applications such as coating nitinol guidewires and over-extrusion of inner and outer catheter layers.
- A dedicated coating die works with core-wire preheating to create a secure bond between the polymer coating and metal core that prevents loosening and delamination.
- The screw and barrel are made of 38CrMoAlA nitrided steel, whereas the extrusion head and die use S136 corrosion-resistant mirror-finished tool steel.
- Multi-zone independent closed-loop temperature control maintains an accuracy of ±0.5 °C for stable plasticization of highly filled modified materials.
- Coating thickness is controlled to ±0.01 mm, with smooth transitions across variable-diameter sections and no abrupt changes in coating thickness.
