Industrial cutting machine parts rotary metal slitting blade
Material and hardness are very important to the work life of metal shearing blades. Production, including heat treatment, therefore is completely entirely in-house, which guarantees a consistent supply of high-quality shear blades with optimum microstructure and optimum mechanical properties. Meanwhile, our team of engineers can provide you with professional advice based on more than 30 years of experience, and recommend the most suitable material and hardness for you at a competitive price according to the application of the blades. In addition, we produce highly precise knives and shear blades with the length of up to 5500 mm, diameter up to 1500 mm.
Application of the circular slitter knives for aluminum foil cutting:
