Industrial Knives

Granulator Knives

Granulator knives are industrial cutting tools used to reduce materials like plastics, rubber, and cables into smaller, uniform pieces for recycling and reprocessing. Their specifications are primarily defined by their material composition, dimensions, and the required precision for the application. Key Specifications Specification Feature Details Sources Material D2 tool steel (1.2379), H13, 440C Stainless Steel, HSS (High Speed Steel), Tungsten Carbide (TC) Inlay, Powder Metal (ASP Inlay), 9CrSi, SKD-11 Hardness (HRC) Typically between 50 and 62 HRC, depending on the material and intended use. Higher hardness increases wear resistance Dimensions Highly variable and customized to OEM machine specifications. Typical ranges for width and height are 30-100 mm (W) and 20-50 mm (H). Lengths can vary from a few inches up to several feet Tolerance Manufactured to exacting standards to ensure precision cutting, typically with a tolerance of 0.02 mm (or 10 microns for critical bearing surfaces) Geometry Straight blades for general purpose and high throughput; Hooked/Curved for tougher, fibrous materials like film or fiber; Toothed for fine grinding and consistent chip size Finish Mirror-polished finishes (Ra ‰0.4 µm) are common to reduce friction, minimize material adhesion, and improve cut quality and ease of cleaning

Guillotine Knives

Guillotine knives are industrial-grade, precision-engineered blades primarily used for cutting large volumes of materials like paper, cardboard, and sheet metal. Their specifications focus on durability, material composition, and exacting dimensions to ensure clean, straight cuts. Key Specifications Specification Feature Details Sources Material High-carbon tool steel, High-speed steel (HSS), Tungsten Carbide (TC) inlay, or Stainless steel. Specific grades include D2 (HCHC), H13, 9CrSi, and SKD-11. Hardness (HRC) Ranges from 58-68 HRC for steel blades; Tungsten Carbide inlay blades are significantly harder, often around 87-90 HRA. Dimensions Highly specific to the machine manufacturer (e.g., Polar, Wohlenberg, Schneider). Typical lengths range from 500mm to over 1785mm. An example is 1095 x 115 x 11.7 mm. Tolerance Manufactured to high precision, with typical tolerances of ±0.02 mm (width and thickness) to ensure a precise fit and reliable performance. Edge Geometry Feature a thin, sharp, straight edge with common bevel angles ranging from 19 to 25 to produce fiber-free cuts. Some specialized applications may use toothed or scalloped edges. Finish Often highly polished and super-honed to ensure precision cutting and to

Cross Cutter Knives

Cross cutter knives are precision tools with specifications that vary widely based on their intended application, which can range from industrial paper cutting to testing coating adhesion. Key specifications include material, dimensions, number of cutting edges/teeth, and adherence to specific industry standards (e.g., ISO, ASTM). Adhesion Tester Cross Cutter Specifications Cross cutter knives used for adhesion testing (also known as cross-hatch cutters) are highly specialized instruments designed to evaluate the adhesion of coatings to a substrate by cutting a grid pattern. Standards Compliance: Designed to conform to international standards such as ISO 2409, ASTM D3359, and BS 3900. Blade Material: Typically made of hardened steel or carbide-tipped steel to ensure sharpness and durability. Number of Cutting Edges/Teeth: Commonly available with 6 or 11 cutting teeth. Cutter Spacing (Pitch): Blade spacing is crucial and varies with the coating thickness and substrate type: 1 mm spacing: For hard substrates (like metal) with film thickness less than 60 µm. 1.5 mm spacing: For film thickness between 61-120 µm on hard or soft substrates. 2 mm spacing: For film thickness between 61-120 µm on hard substrates or thickness < 120 µm on soft substrates (wood, plastic). 3 mm spacing: For hard or soft substrates with film thickness between 121-250 µm.
