How Buyers Describe and Specify This Blade
Industrial teams often use several names for the same blade family. We use those terms to identify the likely application, then confirm the final design from the drawing, sample and machine conditions.
Size and geometry. The terms “dish-shaped circular slitting blade”, “thin circular slitter blade” and “circular knife with custom bore” usually describe geometry or configuration. Requests using “custom thickness round slitting blade” or “precision-ground rotary slitter knife” should confirm critical dimensions and edge orientation.
Application and equipment. Buyers may search for “plastic film rotary cutting knife”, “flexible packaging slitter blade” or “film slitting machine replacement blade” when identifying an application. For requests described as “precision round knife for foil and paper” or “industrial film cutting machine blade”, include the processed material, machine interface and required cut quality.
Custom and replacement supply. Sourcing language can include “custom circular knife for film slitting”, “custom industrial slitter blade manufacturer” or “OEM circular knife from drawing”. Requests using “drawing-based round slitting blade” or “custom OD and bore circular blade” should include an approved drawing or sample details before production.
The approved drawing and application conditions always control the manufactured blade specification.
How to Specify a Custom Circular Knife for Film Slitting
- Confirm outside diameter, bore, thickness, dish depth and rotation direction.
- Describe the film or thin-sheet material, thickness range, line speed and required cut quality.
- Provide the holder drawing, existing blade sample or clear photos of both blade faces.
- Identify current issues such as burrs, dust, edge wear, runout or inconsistent slit width.
