Selecting a high-speed corrugated cardboard production line is a critical investment for packaging manufacturers, as it directly impacts production efficiency, product quality, and long-term profitability. This guide outlines core considerations to help businesses make informed decisions tailored to their operational needs.
(1) Clarify Core Production Requirements
The first step is to align the production line's capabilities with your actual business needs, avoiding over-investment or under-capacity issues.
Define Capacity & Speed Targets
Determine your daily/annual output target (e.g., tons of corrugated board per day) and verify the line's speed (typically 200–400 m/min for high-speed models). Note that actual operating speed is often limited by raw material quality and downstream processes, so prioritize stable speed performance over nominal maximum speed.
Evaluate the line's speed adjustment flexibility to adapt to small-batch, multi-specification production needs.
Confirm Board Specification Ranges
Flute types: Clarify if you need to produce single flutes (A/B/C/E/F) or composite flutes (AB/BC). Ensure the production line is equipped with interchangeable corrugating rolls for quick flute switching.
Paper grammage & width: Define the applicable base paper grammage (liner paper: 120–250 g/m²; corrugating medium: 100–180 g/m²) and maximum/minimum board width (common range: 1600–2800 mm) to match your customer orders.
End-product application: For high-end packaging (e.g., electronics, food), prioritize lines with precise thickness control and surface quality; For bulk industrial packaging, focus on cost-effective, high-throughput designs.
(2)Evaluate Key Components & Technical Performance
The reliability and stability of a high-speed production line depend on the quality of its core components. Focus on the following critical parts:
New Type Rotary Shear and Trimming Integrated Machine
This machine is required to realize high efficiency and high yield for the corrugated cardboard.Its main function are:1.Cutoff waste boards and papers prior to order change,which can provide guarantee for non-stop order changing;2.It can realize the non-cutoff order change for double layer production;3It will cut the wastes and stop when there is machine malfunction.
High Speed Spiral Blade Cutoff Machine (Single Layer,Double Layer,Drum Type)
With high or mid-speed corrugated board production line,it could realize full computer control , auto order changing,and high speed slitting of different lengths of boards.By combing with advanced control mode and high quality machine designing,the needs of customs are fully met and the JUSTU innovation is fully embodied.
NC Servo Thin Blade Slitter Scorer(Gear Rack Type)
As an important piece of equipment in corrugated board line dry end, the equipment can accurately score and precisely slit boards and with use of computerized control and auto order changing functions , wastes caused by shutdown are reduced and the production efficiency is improved.
Stacker series
NC servo double layer up&down stacker
The machine is used for board arrangement,overlapping conveying,stacking and transverse discharge completed at late segment of production lines.It could be able to match with high and mid-speed corrugated paper production lines,realize automatic counting with computer and automatically separate stacks based on preset number of each stack and precisely change the order automatically.
Gantry Type NC Servo Up&Down Dislocation Stacker
It could be able to finish cycling process of automatic board stacking,batching,alternating stacking and transverse discharge.Its end conveying platform and suspension basket transverse discharge form counterweight to each other which greatly reduces cycling time of batches in combination with unique designing of lifting and improves production efficiency and lowers energy consumption and also could be used for corrugated board lines.
Full Automatic Double Layer Down Stacker
Automatic double layer down stacker could be able to complete board stacking ,counting,batching,stacking and automatic transverse discharge etc.The basket is provided with balance weight to improve mechanical efficiency and reduce energy consumption.With high efficiency servo control,the running speed of basket could be improved ,and the circulating period of stack changing is shortened.Thereby it can benefit high speed production and small orders.
Fan Fold series
Auto Touch Line Machine
The production of continuous corrugated board can be realized on the corrugated board production line,that is,a line touching machine and a continuous board stacker are installed on the corrugated board production line.The production process of the touching machine is:install the touching cutter on a pair of touching knife rollers,which are driven by the servo motor to rotate ,and hit the folded transverse mark on the running corrugated board. The production process of continuous cardboard stacker is as follows:in the first step,the climbing conveying department will transport the continuous cardboard with folder marks upward,and then transport it downward to the swing faucet after turning slowly at the high point;The second step is to swing the faucet back and forth and fold the continuous cardboard forward and backward;In the third step,the continuous cardboard folded forward and backward is stacked on the hanging basket platform of the hanging basket stacker.
Control System
The "brain" of the production line, which affects operational efficiency and fault diagnosis efficiency.
Prioritize PLC control systems from well-known brands (e.g., Siemens, Mitsubishi) with a user-friendly HMI (Human-Machine Interface).
Ensure the system supports real-time production data tracking (speed, output, defect rate) and automatic fault alarm & diagnosis to reduce maintenance time.
Consider Raw Material Adaptability High-speed production lines have strict requirements for raw materials, but strong adaptability can reduce production costs and expand product range.
Verify if the line can efficiently process recycled base paper without sacrificing speed or board quality, which helps cut raw material costs.
Check compatibility with special papers (e.g., moisture-resistant liner, white top liner) to meet diverse customer demands.
Analyze Energy Efficiency & Operational Costs
High-speed lines consume large amounts of electricity and require regular maintenance, so long-term operational costs are as important as initial investment.
(3)Energy Efficiency
Select production lines equipped with IE3 or higher efficiency motors and heat recovery systems (reusing waste heat from drying processes for preheating raw materials) to reduce energy consumption by 10%–15%.
(4)Maintenance & Spare Parts
Choose suppliers who can provide timely spare parts supply (especially for core components like corrugating rolls) and on-site maintenance services to minimize downtime.
Inquire about the average maintenance interval and cost per maintenance to calculate long-term operational expenses.
(5) Assess Supplier Strength & After-Sales Service
Supplier Qualifications
Check the supplier's industry experience, R&D capabilities, and customer cases (especially references from enterprises of similar scale and output).
Verify if the supplier has passed international certifications (e.g., ISO 9001, CE) to ensure product quality meets global standards.
After-Sales Service
Confirm the warranty period (≥ 12 months is recommended) and the scope of after-sales services (including installation, commissioning, operator training, and on-site troubleshooting).
Ensure the supplier has a local service team or a designated after-sales contact to provide timely support when equipment malfunctions.
(6)On-Site Inspection & Trial Run
Before finalizing the purchase, an on-site inspection and trial run are essential to verify the equipment's actual performance.
Visit the supplier's factory to inspect the production process of the equipment and check the quality of component processing.
Conduct a full-load trial run with your own raw materials to test the line's speed stability, product quality, and fault tolerance under actual working conditions.
Communicate with existing customers of the supplier to learn about their actual usage experience and feedback on after-sales service.
Final Tips
Do not pursue maximum speed blindly; prioritize the balance between speed, stability, and cost.
Choose a production line with scalable configuration to accommodate future capacity expansion or product upgrades.
