Top & Bottom Knives for a Cardboard Processing Company in the Netherlands

Market Background

In the European packaging and paper products industry, cutting equipment is widely used for corrugated board processing, packaging material production, and automated slitting operations.

As packaging manufacturers increase production efficiency, the demand for cutting tools with stable dimensions, consistent cutting edges, and reliable performance has also increased.

In paperboard cutting systems, bottom knives work together with top knives to perform continuous slitting of cardboard materials. If blade dimensions are inconsistent or edges wear quickly, problems such as rough edges, fiber tearing, or machine downtime may occur.

Therefore, selecting cutting knives that match the equipment specifications is essential for maintaining stable production.

Customer and Application Scenario

The customer in this project is a cardboard processing company located in the Netherlands. Their production line is used for corrugated cardboard and packaging board cutting.

The company required bottom knives installed in automated cutting equipment to maintain stable cardboard slitting operations.

The knives are mounted on the machine shaft and operate together with top knives to perform continuous cutting.

Order specifications include:

These knives must precisely match the machine specifications for stable production.

Our Solution

To meet the customer’s production requirements, we supplied customized bottom knives designed for cardboard cutting equipment.

Accurate Dimensional Control

The knives were manufactured according to the Ø105 × Ø90H7 × 10/8 mm specification. The H7 bore tolerance ensures stable fitting with the machine shaft.

Industrial Tool Steel Material

The knives are made from DIN 1.2067 / O1 tool steel, providing reliable hardness stability and wear resistance for continuous cutting applications.

Controlled Hardness Range

After heat treatment, the hardness is controlled within 58–60 HRC, maintaining blade sharpness while ensuring structural stability during long production cycles.
