PRODUCT FEATURES
Flat die cutting blades are essential tools used in the die-making process for precision cutting across industries like packaging (e.g. corrugated board cutting via steel‑rule dies), printing, and electronics. These blades are typically made of high-carbon steel or alloy steel and undergo quenching and surface decarburization treatments to enhance their hardness—making them suitable for cutting materials of various thicknesses and densities under high pressure.

Non-standard adhesive blades: 7 mm, 8 mm, 9.5 mm, 12 mm
Standard blades (e.g. mirror-finished, ground edge, perforation): 23.6 mm, 23.8 mm
Tall blades: 30 mm, 35 mm, 40 mm, 50 mm
Common heights for rule lines: 22.9 mm, 23.3 mm
0.45 mm (1.27 PT) – for adhesive label cutting
0.53 mm (1.5 PT), 0.71 mm (2 PT), 1.07 mm (3 PT), 1.42 mm (4 PT)
Thickness is selected based on material properties—whether thick or thin—and the complexity of bending, as well as machine pressure.
Tip hardness: HS50, HS52, HS55, HS72, HS76, HS78, HS80
Body hardness: HS48, HS50, HS51, HS52, HS55
Blades are designed with a harder tip than the body to enhance cutting edge formation and extend service life.
30°: Very sharp, ideal for fine cutting but lower pressure resistance
42°: Most common; balances sharpness and durability
52°: Higher pressure resistance and longevity, but reduced sharpness
The smallest recommended bending angle is 20°
Lower angles require slightly softer blades (e.g. HS47 body, HS74 tip) to prevent cracking and ensure smooth bending

Three main types of blade bevels in die making:
Central Bevel (CB) – Also known as Single Bevel or Low Peak
Long Central Bevel (LCB) – Double Bevel or High Peak
Side Bevels (SB / LSB) – For one-sided cutting; includes Short Side Bevel and Long Side Bevel
Side bevels are often preferred for high-volume jobs using thinner paperboard. They feature higher tip hardness, better pressure resistance, and offer stable and durable performance—especially for straight-edge, thick-material cutting and closed-form die designs.
Mirror Finish Blades – Smooth, polished edges for clean cuts
Ground Edge Blades – Sharpened for increased precision
Adhesive Blades – For label and sticker material cutting
Perforation Blades – Used for tear lines
Toothed Blades – With serrated edges for special cutting needs
Wavy Blades – For decorative or special cuts
Creasing Blades – For creating fold lines on materials
Flat die cutting blades are indispensable in industries such as:
Packaging – For die-cutting corrugated boards, cartons, labels
Printing – Precision die cutting in post-press processing
Electronics – For cutting insulating materials and components
Other Light Industries – General non‑metallic material processing
Choosing the right blade type, thickness, bevel, and hardness ensures:
Cleaner cuts
Longer blade life
Fewer reworks
Reduced downtime
Safer, more reliable performance
For precision and reliability in die-making, selecting the right flat die blade is as critical as the machine itself. With a full range of customizable options, Yitai provides blades tailored to the exacting needs of die makers across the globe.
