1 Selection of high-quality cutting rule steel: the steel has a tight molecular structure, the blade is flexible, and there is not much rebound after being bent, and the molecular structure remains tightly coupled.

2 Surface decarburization treatment: Retreat the brittle carbon molecules from the surface of cutting rule, so that the blade will not be brittle when it is bent, which will cause cutting rule to break.

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

4 Extremely high precision: The higher the precision of cutting rule, the shorter the pressure regulation time of the die cutting machine, the lower the mechanical wearing, the faster the production speed, and the better the die cutting effect.
