Corrugator line purchase is generally divided into the whole line purchase, self-selection and upgrade purchase of the original equipment.

The cardboard factory that purchases whole line often has relatively certain sales volume and long-term stable customer group.

Self-selection is generally considered by cardboard factory who do not want to invest more money, but also want to get the corrugator line with good quality, price, performance. In this case, the purchase generally stems from the original corrugator line which has been unable to meet the needs of production or in order to reduce the risk of investment in the new plant, the corrugator line supplier will configure each parts according to the demand.

Upgrade purchase of original equipment is generally the factory who do not want to buy new corrugator line.They may purchase two or three paper splicers to increase the average speed and production efficiency, or retrofit steam pipes to quickly replenish heat and reduce energy consumption, or acquire glue making equipment to improve the adhesion of cardboard.This way of purchasing has little impact on production, less capital investment and benefits can be seen in a short time.

Corrugatorpurchase is a project features long life of equipment, relatively large investment.Cardboard factory should consider a supplier with good faith, timely after-sales service, reliable equipment performance, reasonable equipment price, good reputation when purchasing corrugator.In addition to listen to the introduction by suppliers,potential buyers should also do a field trip.Before deciding to buy, cardboard factory must do a full investigation.

Investigate not only the product specifications and the main flute of the surrounding potential customers, providing the basis for the decision, but to understand the equipment status, management status and customer status of the peripheral compes.There are five main factors to consider when purchasing corrugator line: 1).Door width 2).The maximum speed 3). The product direction 4). The investment scale 5).The optimization direction.

1.Corrugator Width

 

Cardboard factory running corrugator line with the door width of 1800mm and below, the biggest advantage is that the base paper is easy to purchase, the second is the speed and cardboard production process is relatively easy to master.The price of all door width corrugator line is also relatively cheap, the price of standard configuration is about $850,000, it is suitable for all-scale development of cardboard factory, as well as food packaging as the leading products of cardboard factory.

Small door width corugator line also has production and operation limitations.For example, the home appliance kind of carton generally required cardboard door width are wide.More than 1800mm door width of cardboard, all door width corrugator line can not be produced.Therefore, if the cardboard factory has the order of home appliance carton, it needs to consider the purchase of 2000mm-2200mm door width corrugator line.

The door width of 2000mm-2200mm is the most conventional corrugator door width, the base paper of this door width is also relatively easy to purchase, the operation process is also relatively easy to master.2000mm-2200mm door width corrugator is the most mainstream one, it is suitable for the production of most cardboard production enterprises, the price of its standard configuration is between $110,000 to $1,400,000.

                  Table 1：The use range of corrugator with different door widths

 

When cardboard factory develop to a certain stage, the size of the enterprise expanded, and orders like large furniture, home appliances refrigerator are very much needed, this kind of carton requires larger door width, in this case it is necessary to consider the configuration of 2500mm door corrugator2500mm and above corrugator line is suitable for large-scale operation of the cardboard factory, the current standard configuration price of more than $1,700,000

At present, the development of wide, high-speed, automatic corrugator line, improve the operating rates are the corrugated board industry trend.The corrugator line is developing towards a wide width. On the one hand, the width of the paper machine is getting wider and wider. The paper mills are already running 6m wide paper machines or even 10m wide paper machines.On the other hand, the advantages of corugator line in the broad width are lowering trimming loss, increasing production.When purchasing corrugator, considering the factor of the door width, cardboard factory should purchase corrugator with wider door width in the case of adequate budget and superb equipment operation level.

2. The Maximum Speed

 

The selection principle for the high-speed corrugator line should take into account the degree of automation of each single machine, meanwhile, factories should pay more attention to the overall corrugated board production line matching and coordination. For instance, equipped with automatic paper splicer (according to the linear velocity, choose a suitable speed of paper splicer, equipped with quantity according to their own economic conditions), the positive pressure card cartridge single facer (roll change convenient, stable running, high speed), the production control system, internal rising collet (in order to meet the demands of safety, must choose more brakes), automatic thin knife slitter (in order to facilitate rapid change orders, equipped with 2 sets), slitter equipped with three kinds of scoring roll (convex to concave, convex, convex to the flat), spiral crossing cutter, automatic glue making system, gluer (use of touch pressure roll rather than roller pressure).The number of double facer hot plate to match the speed of the corrugator line (the drying part using a spring-type hot plate, of course, the advantages and disadvantages of condensate steam trap must be valued) and so on.

At present, most domestic suppliers can produce corrugator line with a maximum speed of 200m/min and below. The price of standard configuration is about $110,000.

If the speed of 200m/min-300m/min is needed, then domestic excellent suppliers and suppliers of Taiwan brand can produce. The standard configuration price is relatively high, generally between $1,400,000 and$ 2,500,000.

                Table 2：Corrugator Supply in the market under Different Speed

  

If 300m/min and above speed is required, the corrugator line produced by a few excellent suppliers in China and Taiwan can reach this speed. While the speed 300m/min and above produced by foreign suppliers has a wider range of models. In terms of production efficiency, the higher the speed corrugator line, the better.The higher speed means that the production of higher output, and the increase in unit output and efficiency will certainly reduce the paperboard production of coal, electricity and other unit consumption and other labor, financial and other costs.

However, high-speed corrugator line has two points to focus.First,corrugator line speed is too high, the variable cost of paperboard production such as raw paper purchase costs will rise, because the high-speed assembly line often put forward special requirements on paper, such as tensile strength, moisture content.Second, the high production speed of cardboard quality and scrap rate of effective control is also a challenge.Because corrugator line must be supplied with a higher steam temperature to maintain a relatively high running speed, if temperature too low cardboard will be soft.And in the production state of high temperature, once there is a speed fluctuation will inevitably lead to cardboard bending up and down warping, resulting in a waste of brittle. At the same time, at high speed, if there are breaking paper and other circumstances, it will cause loss multiplied.Therefore, before the purchase of high-speed corrugator, cardboard factory in the raw paper purchase, operator skills and other aspects to make full preparation.

3.Products Orientation

 

Cardboard industry has two main product models, one is based on cardboard production, one is based on carton production.

Those who mainly based on cardboard production, generally the volumes of order are relatively high, and more disorderly, short orders are taking too much, the production of each order is relatively all, but the total number of orders is very high.In this case, when purchasing corrugator line, we need to consider the automation of order change.Otherwise, the loss of each order will directly pull up the total loss.When purchasing corrugator, it is recommended to strengthen the configuration of rectifying deviation, automatic glue control, automatic paper splicing and production control system.

Under normal circumstances, the speed of 250m/min, door width of 2.2m or 2.5m corrugator line, the price of standard configuration is about $2,412,000.

Those who mainly based on carton production, in general, each order has large production, but the total number of orders is relatively all.This requirements for this mode of automatic control corrugator will be relatively low.The investment saved in the automatic control part of corrugator line is recommended to be used in the configuration of printing equipment.This production mode, corrugator standard configuration of the price will be relatively low, generally $1,714,000.

4.Investment Scale

 

The investment scale in the cardboard factory below $7,000,000, it is recommended to configure the corrugator line below $2,200,000.This price of corrugator line can be produced by the most domestic excellent suppliers .

Corrugator line with higher price will be much advanced in many aspects like al design, material, intelligence.Cardboard factory should be in accordance with the expected use of life to evaluate the cost of corrugator line.

The investment scale between $7,000,000 and $15 million, it is recommended to configure $2,200,000 to $3,500,000 of corrugator line, and consider the best choice of cost performance within 8 years.

Investment of more than $22.5 million cardboard factory, it is recommended to configure more than $4,300,000 corrugator line.This price of corrugator line though can be produced by the domestic excellent suppliers, it still mainly depends on imported corrugator brand.Whether it is domestic or foreign corrugator line, in the intelligent equipment, equipment life, etc., we should consider the best choice of cost performance within 15 years.

5.Optimization Orientation

Some suppliers in corrugator automation performance is flawed.It is understood that the production control system of some brands of corugator line is not compatible with the ERP system, which will have a bad impact on the future development of automation equipment.

When purchasing corrugator line, we should possibly choose standard spare parts. If corrugator malfunctions, emergency measures will be well implemented.Now a lot of corrugator suppliers are doing very well in this regard, the use of spare parts are universal.

When purchasing corrugator line, cardboard factory should also take into account enough space.Otherwise if to upgrade the corrugator line in the future, such as adding some additional s when upgrading five ply to seven ply, there is no enough space for single machine to put. So reserving enough space for the future equipment transformation of cardboard factory will be more convenient and easier to implement.
