The use of TZM alloy rods for hot runner nozzles processing may face the following disadvantages:
High hardness and high melting point: TZM alloy has high hardness and melting point, which makes the machining process more difficult. Cutting and forming TZM alloy rods requires higher cutting force and working temperature, and may require the use of more wear-resistant cutting tools and advanced processing equipment.
Processing cost: Due to the special properties and difficult processing of TZM alloy, processing TZM alloy rod may require longer processing time and more complicated processing. This increases processing costs, including equipment and labor costs.
Processing limitations: The special properties of TZM alloy rods may impose certain limitations on processing. For example, due to its high hardness, it may not be suitable for some complex shape machining or fine machining. This may limit flexibility in design and manufacturing.
Welding Difficulty: TZM alloys have poor weldability and may require special welding processes and materials. This adds to the complexity of manufacturing and servicing of hot runner nozzles.
Potential material damage: During processing, due to high hardness and special properties, TZM alloy rods may be susceptible to damage such as scratches, cracks or deformation. This may reduce the quality and performance of the final product.
