In the plastic crushing process, tools withstand huge impact and friction. With the continuous improvement of the strength of engineering plastics (such as the widespread application of glass fiber reinforced materials), higher requirements are placed on the performance of crusher tools. In 2025, tool technology has made breakthrough progress in material science and structural design.
Breakthroughs in Material Science: Beyond SKD11
For a long time, SKD11 (cold work die steel) has been the mainstream material for crusher tools due to its good wear resistance and toughness. However, facing high-strength plastics with more than 30% glass fiber, the wear rate of SKD11 is still relatively fast. In 2025, Powder Metallurgy High-Speed Steel (PM-HSS) and hard alloy inlay technology began to be widely used on high-end crushers.
Powder metallurgy steel has an extremely fine grain structure and uniform carbide distribution, making its wear resistance and toughness significantly improved, with a service life 3-5 times that of SKD11. For extreme working conditions, composite tools with tungsten carbide hard alloy inlaid on the cutting edge, although more expensive, bring extremely high cost-effectiveness to continuous production enterprises due to their ultra-long maintenance-free cycle and ultimate wear resistance.
Innovation in Structural Design: Targeted Cutting
In addition to materials, the structural design of tools is also more refined. For different material characteristics, crushers in 2025 provide diversified rotor structures.
Heat Treatment and Surface Modification
Advanced heat treatment processes, such as Cryogenic Treatment, are widely used to eliminate residual stress inside tools and further improve hardness and dimensional stability. In addition, PVD coating technology (such as Titanium Nitride coating) has also begun to be applied to crusher tools, providing a super-hard protective film for the cutting edge, reducing the friction coefficient, and reducing material sticking.
