To improve the service life of Manhart CNC bending machine molds, attention needs to be paid to the following aspects:

1. Material selection: Choose mold materials with high strength and wear resistance, such as high-quality steel or hard alloy, to improve the durability and stability of the mold.
2. Structural design: Reasonable mold structure design can improve its stiffness and strength, reduce stress concentration and deformation phenomena. In addition, adopting a combination or splicing structure can facilitate maintenance and replacement of vulnerable parts.
3. Manufacturing process: Advanced processing equipment and technology are adopted to ensure the accuracy and surface quality of the mold. At the same time, heat treatment and surface strengthening treatment are carried out on the mold to improve its hardness and corrosion resistance.
4. Use and maintenance: Proper use and regular maintenance are important measures to improve the lifespan of molds. During use, operating procedures should be followed to avoid adverse conditions such as overloading and overspeed. Regular maintenance such as cleaning, lubrication, and tightening, as well as inspection and repair of vulnerable parts, can maintain the good condition of the mold.
5. Storage and transportation: During the storage and transportation process, the mold should be avoided from impact and vibration to avoid damage. Meanwhile, maintain an appropriate storage environment to avoid adverse factors such as moisture and corrosion that may affect the lifespan of the mold.
6. Control of machining allowance: During the bending process, the machining allowance should be reasonably controlled to avoid excessive bending force causing damage to the mold. By selecting appropriate lower mold shape and bending process parameters, the machining allowance can be evenly distributed, which can reduce the load and wear of the mold.
7. Preventive maintenance: Regular preventive maintenance of molds, such as inspection, adjustment, and replacement of vulnerable parts, can detect and repair potential problems in a timely manner, avoiding the expansion of faults and affecting the lifespan of molds.
8. Information management: Using information management methods to record and analyze the use and maintenance of molds, providing a basis for developing maintenance plans and optimizing usage methods. Through information management, work efficiency can be improved and the service life of molds can be extended.

In summary, improving the service life of Manhart CNC bending machine molds requires comprehensive consideration of multiple factors such as materials, design, technology, and maintenance. In practical operation, corresponding measures should be taken according to the specific situation, and management and maintenance work should be strengthened.
