nouvelles de l'entreprise Corrugated cardboard production line: selecting the correct equipment is the most important

As a manufacturer of corrugated cardboard equipment, what kind of machine should you choose? In fact, the key is to calmly evaluate one's actual needs. Focus on the essential modules and main configurations of the production line, as these directly determine the production capacity of the machine and the core competitiveness of the factory.

1.Before buying a machine, there are several main issues you need considering carefully:
Market and Product Positioning: Who are your target customers? Do you mainly make regular cardboard boxes or high-quality packaging boxes?
Capacity and speed: How much daily and monthly output do you expect to reach?
Investment and return: How much budget do you plan to invest for the equipment and How long do you hope to receive the cost?
Venue and conditions: Is the factory space enough? Whether the supply of electricity and steam can keep up?

2.Let's get to know the core modules of the production line.
A complete corrugated cardboard production line is mainly divided into three parts: wet part, dry part, and intelligent control system. You need to know the function for each part.
Wet part: single-facer machine and paper feeder
Single-facer machine: responsible to bonding face paper and core paper into a single-layer corrugated cardboard, it is the heart of the whole line. The most popular is the cassette type single-sided machine, which has a fast edge changing speed (for example, it takes a few minutes to change rollers compared to BHS module machines), it's very suitable for production that frequently changes orders. When selecting, yoo need pay attention to the length of the corrugated roller (the diameter of the high-speed line is preferably above 375 millimeters), and the heating should be evenly.
Automatic paper feeder: It can ensure continue production without stopping and greatly reducing the waste of raw paper. When selecting, you need consider the success rate of paper splicing, stability in tension control, and adaptability to lightweight base paper. Of course, its speed needs to match the whold line, and the installation space also need enough large.
Dry part: Vertical and Horizontal Cutting Machines
Vertical cutting and creasing machine: it responsible for cutting and pressing creases on cardboard. Now we recommended to use a fully automatic thin blade longitudinal cutting machine, which is fast in changing orders (can be completed within one second) and it has high accuracy (error ± 0.5 millimeters), especially suitable for production with large orders and frequent changes.
Cross cutting machine: responsible for cutting cardboard according to length. For high-speed production lines (speed ≥ 150 meters/minute), spiral knife cross cutting machines are almost standard, cutting more smoothly, with long blade life, and the accuracy controlled within ± 1 millimeter. For low-speed lines, you can choose a low-cost straight knife cross cutting machine.
Efficiency multiplier: intelligent control system
Nowadays, high-end production lines are install with intelligent management systems. It can achieve automatic cruising, data monitoring, automatic scheduling, and optimized production of the whole line. This will not only improve efficiency, but also is the key to moving towards intelligent factories and achieving refined management.

3. Some supporting facilities and details cannot be ignored.
In addition to the core devices mentioned above, the following are also important:
Glue application system: It is best to use an adjustable pressure contact rod type glue application instead of heavy pressure rollers, which can avoid flattening the corrugated surface, make the glue more uniform, and improve the strength of the cardboard.
Drying system: The number of heating plates for the double-sided machine should match the production line speed (usually not less than 18 for high-speed lines). Consider using structures such as vacuum adsorption traction to make the cardboard stick more firmly.
Raw paper holder: It is recommended to use an internal expansion clamp to avoid bursting the paper tube and reduce waste of raw paper.

4. Brand and equipment supplier reference
International big brands, such as BHS from Germany and Fosber from Italy, provide high-speed and intelligent overall solutions with leading technology.
Domestic large enterprises such as Hubei Jingshan Light Machinery and Guangdong Dongfang Precision Machinery have good equipment in terms of performance, intelligence, and energy saving, with more competitive prices and fast service response.
Featured advantage brands: Some manufacturers specialize in specific areas, such as Qingdao Kaida CNC's fully automatic longitudinal and transverse cutting machines, and Shanghai Baumer hhs' spray coating and quality inspection equipment.

5. Suggestions for your purchase:
Internal clarification: Use the list of issues mentioned earlier to clarify your market demand, product planning, and investment budget.
Conduct extensive research: participate in industry exhibitions such as the "China International Corrugated Exhibition" to personally see and compare equipment from different manufacturers. Visit several factories that have already installed equipment and listen to real feedback from actual users.
Focus on in-depth discussions: Based on the research results, select 3-5 qualified suppliers for key discussions. Make sure they provide a detailed configuration plan and quotation tailored to your specific needs.
The contract needs to be carefully reviewed: In the contract, it is necessary to clearly state the performance indicators of the equipment (such as speed, energy consumption, qualification rate), acceptance standards, payment methods, delivery time, after-sales service terms, and spare parts supply.

Remember, selection is a comprehensive decision-making process. There is no "best" device, only a configuration that is'"most suitable "for your current and future development needs. Hope you can find a "right" euqipment for your factory.
