Trimming Mould Tool Steel
Fushun are main manufacturer of tool steel for Trimming Mould.
What is Trimming Mould?
Trimming moulds are precision tools designed for removing excess material or flash from formed parts, particularly after forging, stamping, or casting operations. These moulds consist of carefully engineered cutting edges, support structures, and guiding systems that work together to achieve clean, precise cuts along predetermined trim lines. The design emphasizes accurate alignment and proper clearances to ensure consistent cutting quality.
The main function of trimming moulds is to achieve final part dimensions by removing unwanted material from workpieces. They are extensively used in automotive, aerospace, and general manufacturing industries to finish parts like forgings, castings, and pressed components. Trimming moulds can handle various material thicknesses and shapes, operating at high production rates while maintaining precise cut quality and dimensional accuracy. This process is crucial for preparing parts for subsequent operations or final assembly.
The materials used in trimming moulds require specific alloying elements to provide optimal performance under repeated impact and shearing forces. These tool steels typically contain high percentages of chromium (8-12%), tungsten (2-6%), and molybdenum (1-3%) to achieve the necessary hardness and wear resistance. The material composition enables hardness levels of 58-62 HRC while maintaining adequate toughness to prevent chipping. The microstructure features uniformly distributed carbides that provide excellent wear resistance and edge retention. Special heat treatments and surface modifications are often applied to enhance durability and reduce maintenance requirements.
