Customized sizes are available, according to your drawing or sample.
YISHI Machinery supplies stator blades (fixed knives) for single shaft shredders used in plastic, wood, metal, and tyre recycling — customers frequently pair these with our plastic crusher blades for complete granulator and shredder blade assemblies. Our stator blades are machined from high-alloy tool steels—D2 (1.2379), SKD11, Cr12MoV, and HSS—with vacuum heat treatment to HRC 58–62 for maximum wear resistance. Blades are surface-ground to Ra 0.4–0.8 µm and held to a tolerance of ±0.01 mm across critical dimensions. Whether you require standard sizes for machines such as Vecoplan, Weima, Lindner, or SSI, or fully custom profiles, our engineering team works directly from your drawings or OEM part numbers. We serve procurement engineers and plant maintenance teams seeking consistent cut quality and reduced blade change-over frequency.
Hardened to HRC 58–62 for D2/SKD11/Cr12MoV grades; HSS options available for elevated temperatures and abrasive materials.
Surface finish Ra 0.4–0.8 µm achieved through precision grinding, reducing friction and material adhesion.
Critical dimensions held to ±0.01 mm, ensuring accurate fit and consistent shredding gap.
Blades manufactured to match or exceed OEM specifications for machines like Vecoplan VAZ, Weima WLK, Lindner Micromat, SSI, and others.
Mounting holes, counterbores, and slots machined to your exact specifications from drawing or CAD file.
TiN, TiCN, or DLC coatings available for extended service life in high-wear applications such as glass-filled polymers or metal scrap.
o make sure your customized blades is simple. Just send us the drawing or essential information of the blades. Our proficient engineers will take care of the rest.
We are more than happy to provide prompt offer as per your needs.

YISHI Machinery has over 15 years of experience in industrial blade manufacturing, with a dedicated tool steel heat treatment facility ensuring consistent hardness across every batch. Our in-house CNC grinding and wire EDM capabilities allow us to hold tolerances others cannot. We maintain an inventory of D2, SKD11, and HSS blanks to shorten lead times for urgent orders. Every stator blade is inspected with a CMM and hardness tester before shipment, with full material certification provided. We support low-volume prototyping and high-volume production, and our engineering team provides application-specific material recommendations to maximize blade life in your process.
We primarily use D2 (1.2379), SKD11, and Cr12MoV for standard applications. For high-temperature or abrasive conditions, we offer HSS (M2) or tungsten carbide options. Material selection depends on the shredded material and desired blade life.
Yes. We produce stator blades compatible with all major single shaft shredder brands, including Vecoplan, Weima, Lindner, SSI, and others. Provide the OEM part number or a drawing, and we will match the dimensions and mounting configuration.
We hold ±0.01 mm on cutting edges and critical mounting holes, with positional tolerances of ±0.02 mm. This ensures proper alignment and consistent shredding gap.
You can email PDF, DWG, or STEP files to our engineering team. Include dimensions, material preference, and hardness specification. We will provide a quotation within 24 hours.
Standard lead time is 30 days after deposit. For urgent orders, we can expedite to 15–20 days using in-stock tool steel blanks, depending on complexity.
Yes, we offer TiN, TiCN, and DLC coatings to enhance wear resistance and reduce friction. Coatings are applied after heat treatment and grinding, and are recommended for abrasive materials like glass-filled plastics or metal scrap.
