View Product Description

High-precision tungsten carbide corrugated paper roll

The wear-resistant tungsten coated roller is highly efficient because it symbolizes the most advanced technological development in the corrugated packaging industry. The combination of high-precision grinding and cobalt-tungsten coating can extend the service life of the rollers and is economically feasible at the forefront of production. Meijia provides flute and product quality certification. Such rolls are perfectly synchronized with single-face machines and automatic corrugated paper mills to maximize the return on investment. The following are some technical knowledge and product advantages:

technical knowledge:

1. Drum material

Tailored. However, the most commonly used 50CrMo alloy steel forgings.

2. Range of coating thickness

0.06 to 0.08 tungsten coating thickness

3. Tailor-made rollers for economically feasible production processes

4. Hardness: Roller hardness> 59-62 HRC

5. Highly advanced heating and tempering unit

6. High precision grinding

7. Hot groove/CCS

Excellent heat transfer performance improves production quality and avoids scaling of the insulating film on the surface of the roller.

8. Laser profiler

Precise contour testing to produce the best results.

Product advantages:

1. Anti-friction performance:

2. Cost saving:

3. Reduce the cost of linear corrugated rollers per meter by more than 70%, 5-10%, reduce paper consumption by 2-5%, reduce waste (waste)

4. Longevity:

The life span is increased by more than 150-200%.

5. Excellent demoulding performance:

Improve quality and increase productivity:

6. Strength:

The strength of corrugated board increased by more than 20%
