Product Description
Plastic crusher blades are key components installed in plastic pulverizers. They are used to cut and crush various plastic products such as plastic bottles, films, pipes, plates, etc. into small particles or fragments for easy recycling or reprocessing. Plastic crusher blades refer to industrial knives used in plastic pulverizing equipment to break plastic products into small pieces through the shearing action between the rotating and fixed knives.
Granulator blades are typically made of high-quality materials such as tool steel, stainless steel, or hardened carbon steel to ensure durability and performance. Granulator blade is a key component used in granulators to cut, crush, or grind materials into granules.

Advantages of plastic crusher blades and granulator blades:
1. High Cutting Efficiency
Sharp, durable blades shear plastic quickly, reducing processing time and increasing output.
2. Uniform Particle Size
Properly designed blades produce consistent, evenly sized granules, ideal for downstream reuse or extrusion.
3. Versatility
Suitable for a wide range of plastic materials (e.g., PP, PE, PET, PVC, ABS, PC), including hard and soft plastics.
4. Long Service Life
Made from wear-resistant steel (like SKD-11 or D2), the blades can withstand heavy-duty use and maintain sharpness over time.
5. Energy Efficiency
Efficient cutting reduces machine load and power consumption, minimizing operational costs.
6. Easy Maintenance and Sharpening
Most blades are removable and can be resharpened multiple times, reducing replacement costs.
7.Wear resistance
By using materials such as tool steel (such as D-2 steel), high-speed steel (such as M2 steel), or hard alloy, it can effectively resist frictional losses during material cutting, extend blade replacement cycles, and reduce equipment maintenance costs. For example, when processing high hardness plastics, the service life of hard alloy blades can be increased by 3-5 times compared to ordinary steel blades.
8.Good hardness and toughness
Tool steel and high-speed steel have both high hardness (up to 60HRC or above) and a certain degree of toughness, which can ensure the sharpness of the blade and avoid easy breakage under impact loads. High speed steel blades can reduce blade damage caused by repeated impacts when handling elastic materials such as rubber.
9.Corrosion resistance and high temperature resistance
Some special materials, such as stainless steel coated blades, can resist the erosion of corrosive materials, such as plastic waste containing acid and alkali, and are suitable for complex working conditions such as waste recycling; The thermal hardening of hard alloys enables them to maintain cutting performance even in high-temperature environments, such as the molten state during plastic granulation.
We stick to the principle of "quality first, service first, continuous improvement and innovation to meet the customers" for the management and "zero defect, zero complaints" as the quality objective.
