The production method of perforated mandrels from molybdenum alloys (such as TZM) typically involves several key stages:

Material selection: First choose high-quality molybdenum alloy materials, such as TZM, which is a composite material of molybdenum, titanium, zirconium and carbon.  TZM has excellent high-temperature strength, good thermal conductivity, wear resistance and deformation resistance, making it an ideal material for punching mandrels. Mechanical processing and forming: Using advanced machining technology and equipment, the molybdenum alloy material is formed into the required shape of the punching mandrel. This may involve turning, milling, grinding or other precision machining processes to obtain the required dimensions and surface finish. Heat Treatment: TZM can undergo a heat treatment process to improve its mechanical properties, dimensional stability and overall performance at high temperatures. This may involve controlled heating and cooling cycles to achieve the desired material properties. Surface Treatment: Apply a surface treatment or coating to enhance the wear resistance, surface hardness and overall durability of the pierced mandrel. This may include processes such as chemical vapor deposition (CVD) or physical vapor deposition (PVD) to form a protective coating. Quality Control: Strict quality control measures are implemented throughout the production process to ensure that the molybdenum alloy punched mandrels meet precise tolerances, dimensional accuracy and performance requirements. Final Inspection and Testing: A thorough inspection and testing program is conducted to verify the integrity and performance of the finished piercing mandrel. This may include dimensional measurements, surface analysis and performance testing under simulated operating conditions. The production of molybdenum alloy piercing mandrels requires careful attention to material selection, precision machining, heat treatment and quality assurance to ensure the final tool meets the demanding requirements of metal piercing and forming applications.
