Application :	mainly used in paper making machinery and paper roll industry
Blade manufacturing process:	The shape of the blade is round, and the blade needs to go through the processes of cutting, forging, shaping, turning shape, heat treatment, grinding outer circle, inner hole, fine grinding, turning knife edge, storage, packaging, storage, etc.

Jiangsu Leizhan Group is a development, production, technical consulting, engineering design, business and sales into one company.

First of all, the advanced manufacturing process can ensure a longer service life of the blade, a lower wear rate of the roller surface, and can produce high-quality paper products. Secondly, a complete logistics system can enable us to ship to all parts of the world in the fastest time. On the basis of high quality, we are committed to developing new products with high technology content. Enhance market competitiveness and expand market.
