EXPERT IN TUNGSTEN CARBIDE CUTTING AND SLITTING TOOLS

Expert in tungsten carbide cutting and slitting tools

The tungsten carbide cutting and slitting blades made by powder metallurgic method are widely used for

the cutting of non-ferrous metals, cardboard/paper, chemical fibers, graphite and plastic. Due to its high

hardness, wear resistance and corrosion resistance tungsten carbide is the ideal material for any cutting

device.

The components of our tungsten carbide are WC (hard phase) and cobalt (binder phase). The physical

properties and the alloys depend on the grain size of WC and the percentage of hard phase and binder

phase, resulting in different material grades for different applications.

APLLICATION

APLLICATION

Sichuan Shen Gong Carbide Knives Co. Ltd. is located in Sichuan Province, Chengdu City, in the southwest airport development zone Shuangliu. It developed from its predecessor Chengdu Siruite Carbide Knives Co. Ltd. to its current form and now covers 29000 (building area is about 25000 ) and employs 300 people in total. The company boasts an integral production line ranging from WC powder preparation to finished carbide knives/blades. Our machine park features more than 500 machines.

With more than 20 years of experience in the production of tungsten carbide cutting and slitting knives/blades, we specialize in corrugated board cutting blades and other circular blades which are all made from virgin material. More than half of our products are used in the overseas markets. Our corrugated board cutting blades of our brand ”Jingrui” won the “technologies innovation awards” of Sichuan Province. Our ”SRT” (Shen Gong Royal T) blades used for cutting lithium battery poles as well as our industrial blades are leading in the domestic and global market. Shen Gong (meaning: “heavenly tools”) qualities meet highest standards and requirements.

Our Goal: We want to prove that as a Chinese manufacturer we are a quality maker of the 21st century with excellent products, just-in-time deliveries and great customer service. We believe in product development, sustainabil i ty, eco-fr iendly production and long-term customer relationships.

ANALYSIS OF TYPICAL PROBLEMS OF CORRUGATED BOARD SLITTING BLADE

Expert in tungsten carbide cutting and slitting tools

Problem 1: The short lifespan of corrugated board blades.

A. Is the grain size of the grinding wheel adequate?

Too coarse a grain size of grinding wheel shortens the lifespan/performance time of blades.

B. Excessive grinding: the grinding interval is too short or the grinding pressure is too high.

Problem 2: The edges of corrugated boards cut by blades show burrs and dents.

A. Please check the cutting edge of your blade. Is the cutting-edge sharp enough?

B. The corrugated board is too wet.

Problem 3: Breakage of blades.

A. incorrect assembly e.g. deformed flange plate; wrong screwing will cause the breakage of

blades.

B. Unstable swing grinding wheels break the blades; please check the bearing of the grinding

wheels.

C. The problem may be caused by collision with other hard objects.

Problem 4: Chips on the cutting edge after the grinding.

A. Unstable swing grinding wheels may cause this problem, even break the blades.

B. A collision with hard objects may cause the chips on the cutting edge.

Problem 5: The edge of corrugated board is not straight.

A. The hardness of the blade and corrugated board might not match.
