2. Exquisite surface carbon removal treatment for cutting rule: the brittle carbon molecules are removed from the surface of cutting rule (for laser die), so that cutting rule will not be brittle when it is bent.

3. Excellent heat treatment for cutting rule: The cutting rule can be adjusted to different hardness according to different requirements of customers, cutting rule body is softened to facilitate bending and cutting rule peak is hardened to make it durable.

4. Extremely high precision: The higher the precision of the cutting rule, the shorter regulating time of the die cutting machine, the lower the mechanical wearing, the faster the production speed, and the better the die cutting effect. In particular, the die-cutting of the self-adhesive trademark, the precision-free die-cutting rule is not qualified at all.
