Recently, a customer from the packaging industry visited our factory to test the cutting performance of 2A and 3A corrugated boards.
In this article, we will share the challenges they faced and how our ZCRB2516 dual-tool oscillating knife cutting machine helped solve the problem.
Customer Background & Material Requirements
This customer mainly produces heavy-duty packaging boxes for large equipment and e-commerce logistics, so they require very high structural strength for their packaging materials. To improve compression resistance, they widely use double-wall (2A) and triple-wall (3A) corrugated boards in their production.
Core Challenges in Traditional Cutting Process
However, as their order volume increased, they began to encounter several challenges in the cutting process.
The first issue was the thickness of the material. 2A and 3A corrugated boards are typically 8–15 mm thick, with a strong and rigid structure. When using traditional die-cutting or conventional cutting equipment, problems such as incomplete cutting, crushed edges, or the need for secondary trimming often occurred. This not only reduced production efficiency but also affected the final product quality.
The second challenge was more complex packaging structures.
As customer requirements evolved, their packaging designs were no longer limited to simple rectangular boxes. Instead, they included locking structures, cushioning designs, and irregular folding lines. Traditional die-cutting methods require new dies for each design, which leads to high tooling costs and long development cycles. Every new sample could take several days to prepare.
The third issue involved material stability.
Because 3A corrugated board has multiple layers and a complex internal structure, unstable pressure or improper blade control during cutting may lead to surface tearing or collapse of the flute structure.
For reference:
2A Corrugated Board (professional term: Double Wall AA Flute Corrugated Board)
This structure has greater thickness and excellent cushioning performance, and is commonly used for heavy-duty transportation packaging.3A Corrugated Board (professional term: Triple Wall AAA Flute Corrugated Board)
It provides higher compression strength and is suitable for large equipment and heavy product packaging.
Solution: ZCRB2516 Dual-Tool Oscillating Knife Cutting Machine
After understanding the customer's requirements, we arranged for our engineers to conduct on-site tests and recommended the ZCRB2516 dual-tool holder oscillating knife cutting machine.
The biggest advantage of this machine is its dual-tool holder design, which allows different tools to be installed for different materials. For example, one side can be equipped with an oscillating knife for efficiently cutting thick corrugated boards, while the other side can be equipped with a creasing wheel or drag knife for creating folding lines. This combination offers great flexibility when processing packaging materials.
On-Site Test Results & Performance Verification
During the on-site test, we first performed cutting tests on 2A corrugated board. The oscillating knife moves up and down at high speed, allowing the blade to smoothly penetrate the multi-layer board structure. The cutting process was very smooth, and the edges were clean and neat without crushing or burrs.
Next, we tested 3A corrugated board. Since the material is thicker, our engineer adjusted the oscillation frequency and cutting pressure accordingly. After optimization, the machine was still able to cut the thick board stably while maintaining excellent cutting precision.
After completing the material tests, the customer also tried cutting several irregular packaging design files. By simply importing the design file, the machine could automatically follow the cutting path. No die-making was required, which greatly shortened the sample development time.
Customer Feedback & Value Summary
At the end of the testing session, the customer was very satisfied with the machine's performance. They mentioned that this digital cutting solution could significantly improve sampling efficiency, production flexibility, and material utilization, while also reducing the cost of making cutting dies.
