If you are a corrugated box factory owner ready to purchase a 5-ply corrugated board production line, you may find that different suppliers offer different quotations for 5-ply automatic corrugation plants. Why do different corrugated machinery manufacturers offer different prices for what seems to be the same 5-ply corrugator line? When comparing prices, which configurations should you focus on, and how can you choose the right solution for your production needs? With these questions in mind, let's explore the price of a 5-ply automatic corrugation plant.
How Much Does a 5 Ply Automatic Corrugation Plant Cost?
Simply put, the reference price range for a 5-ply automatic corrugation plant is approximately $190,000 to $280,000. Even for 5-ply automatic corrugation plants, differences in working width, production speed, and equipment configuration influence the final quotation.
The table below shows an example of a 5-ply automatic corrugation plant configuration.
| Item | Specification |
|---|---|
| Maximum Working Width | 1800 mm |
| Design Speed | 100 m/min |
| Economic Speed | 0-75 m/min |
Please note that this price range is for reference only. The table does not represent a fixed configuration for the price range above. The actual price depends on the production line configuration and procurement requirements.
Next, let's look at what equipment a complete 5-ply automatic corrugation line usually includes, and then analyze how different configurations influence the price.
What Equipment Is Included in a 5-Ply Automatic Corrugation Plant?
Before comparing quotations for 5-ply automatic corrugated board production lines from different suppliers, you need to understand what equipment a complete production line usually includes. You also need to know what each part does.
Double-wall corrugated board consists of 3 linerboard layers and 2 corrugated medium layers. During production, the paper rolls pass through several stages. These include preheating, corrugating, gluing, cutting, and stacking.
A complete production line includes not only the main processing equipment, but also the corresponding conveying system and auxiliary equipment.
-
Mill Roll Stand, Reel Loading Car and Preheater
The mill roll stand is used to hold paper rolls for the top, middle, and bottom liners, as well as the corrugating medium. It prepares paper rolls for continuous feeding in the corrugated board production line. The reel loading car assists with loading and replacing base paper rolls.
The preheater heats the paper through heating rollers. This prepares the paper for corrugating and gluing. Depending on the production configuration, a triple preheater can also be used.
-
Single Facer and Corrugating
The single facer presses the corrugating medium into a wavy shape with the corrugating rollers. It then bonds the corrugated medium with the liner paper through the gluing system to form single-face corrugated board. 5-ply corrugated board has two corrugated layers. Therefore, a 5-ply automatic corrugation plant uses two single facers to form the two corrugated medium layers.
Different corrugating roll configurations can produce different flute types. Which corrugating roll to choose depends on the type of corrugated board you want to produce.
-
Overhead Bridge and Board Conveying System
The corrugated bridge system connects the single facer and double facer. It is used to convey and temporarily store single-face corrugated board.
-
Gluing System and Double Facer
After the single-face corrugated board is formed, it still needs to be bonded with other paper layers to form a complete five-ply structure.
The gluing machine is responsible for applying glue to the corrugated flutes.
The double facer uses heat and pressure to bond the two single-face corrugated webs with an additional linerboard layer, forming continuous five-ply corrugated board.
-
Slitter Scorer and Cut-Off Machine
The slitter scorer cuts corrugated board to the required width and presses the creasing lines. The NC cut-off machine cuts corrugated board continuously to the set length. Different equipment control methods and adjustment options are available to meet the requirements of different order sizes.
-
Automatic Stacker and Auxiliary Systems
The automatic stacker is responsible for organizing and stacking the cut corrugated board, facilitating subsequent handling and processing.
In addition, the 5-ply automatic corrugation plant also needs auxiliary equipment such as a glue-making system and an electrical control system. Check whether the steam system, boiler, and air compressor are included in the quotation. After understanding the main equipment in a 5-ply corrugated board production line, we can look at which configurations affect the price of the complete line.
Which Configurations Affect the Price of a 5-Ply Automatic Corrugation Plant?
Different suppliers may offer different quotations. Besides production speed, working width, and automation level, it is necessary to understand the specific equipment configurations of each production line. You also need to check whether the quotation includes related auxiliary equipment and systems. Let's first analyze the following aspects.
-
Working Width and Production Speed
Working width and production speed are important factors to consider when comparing 5-ply automatic corrugation plants. Production lines with different specifications may vary in equipment configuration and production capacity.
When comparing prices, besides considering the design speed, it is also necessary to understand the equipment's economic speed and the speed it can achieve under actual production conditions.
-
Single Facer Configuration
The 5-ply corrugated board production line is usually equipped with two single facers. When comparing prices, you need to first check the machine models, working width, design speed, and corrugating roll diameter.
Different models and configurations result in different quotations. Therefore, don't just look at the quotation sheet stating "5-ply corrugation line." You also need to understand the specific configuration. Only by checking these main specifications can you determine whether the equipment offered by different suppliers is comparable.
-
Slitting, Cutting and Stacking Equipment
The slitter scorer, cut-off machine, and automatic stacker also need to be checked for their specific models and specifications. If you produce cardboard in many sizes and orders change frequently, the equipment may need greater adjustment flexibility.
When making a purchase, you can check whether the equipment meets your needs based on commonly used cardboard sizes, order change frequency, and production arrangements. You do not always need to choose higher-specification equipment.
You also need to check the automation features of these machines, such as automatic size adjustment and stacking functions. Different automation configurations may also affect the quotation.
-
Auxiliary Equipment Configuration and Supply Scope
Whether the quotation includes the glue-making system, electrical control system, and steam system needs to be confirmed item by item. Steam boilers, air compressors, and some piping may also need to be provided by the customer. You also need to ask whether installation, commissioning, and training are included.
Is the Quote for Your 5-Ply Corrugator Line Reasonable?
When consulting suppliers about quotations for a 5-ply automatic corrugation plant, the following three situations may arise.
-
Higher Price, Different Configuration
If one supplier's quotation is much higher than those from other suppliers, do not assume the price is too high and give up on this supplier. You need to check the working width and design speed of the automatic corrugation plant in the quotation. Make sure both suppliers are offering 5-ply corrugated board production lines with similar specifications.
Then, check which machines are included in the production line. Check whether the models, quantities, and configurations are similar. This helps you avoid cases where one quotation includes some equipment or functions, but the other does not. You need to check the equipment configurations and what is included in both quotations. This will help you judge whether the price difference is reasonable.
-
Lower Price, Incomplete Configuration
If one supplier's quotation is much lower than those from other suppliers, but the configuration list does not provide complete equipment information, you need to first check which machines are included in the quotation. Check whether all the main machines in the 5-ply corrugated board production line are listed. These may include the mill roll stand, single facer, double facer, slitter scorer, cut-off machine, and stacker. You also need to check whether these machines are included in the current quotation or need to be purchased separately. If some machines are not listed, or the supplier does not clearly state whether they are included in the quotation, you need to ask the supplier for confirmation. Otherwise, you may find that even if the initial quotation is low, you still need to buy other equipment later. The actual purchase cost will be higher.
-
Similar Configuration, Different Prices
If two suppliers offer 5-ply corrugated board production lines with similar working widths, design speeds, machine configurations, and scopes of supply, but their quotations are still very different, you need to check the equipment specifications and configurations in more detail. For example, check the models of the main machines, the material and heat treatment of the corrugating rolls, the drive structure, and the electrical components.
Even if two suppliers offer machines with the same names, their configurations may be different. These differences may affect the equipment price. You also need to check whether both suppliers include the same installation and commissioning services, operator training, spare parts, and after-sales support.
If these are also similar, you can learn more about the suppliers' manufacturing experience, equipment performance, and after-sales service. Then, you can judge whether the price difference is reasonable.
Note: Do not choose a supplier just because its quotation is lower. A higher price does not always mean better equipment. You need to find out why the prices are different and make your decision based on your production needs and budget.
