The production line is suitable for the automatic production of 10-20 liters’square can. total power: approx.90KW,total floor space: 250㎡ .total length:approx.33 meters. total manpower: 4-5 people. Production capacity: 20-23cpm. Square can’s height range: 170-450mm. Square can’s diagonal range：300-320mm

Technical flow: cutting the tin sheet to blank—rounding—welding—inner and outer coating (inner powder coating and outer coating)-drying-cooling conveying-square expanding-panel,corner embossing-upper flanging-lower flanging-bottom lid feeding-seaming-turning over-top lid feeding-seaming-leak testing-packaging

It is made of three pieces of metal sheet (mostly tinplate), the can body, the bottom and the lid. The can is square shaped. The body of the can has embossing on all sides, and on four corners. The big square can range: capacity 10-20L, diagonal 300-320mm, height 170-450mm.

First place the cut can body materials into the automatic resistance welding machine’s feeding table, Suck by the vacuum suckers,send the tin blanks to the feeding roller one by one.through the feeding roller, the single tin blank is fed to the rounding roller to conduct rounding process, then it will be fed to the rounding forming mechanism to make rounding.The body is fed into the resistance welding machine and make welding after the accurate positioning. After welding, the can body is automatically fed into the rotary magnetic conveyor of the coating machine for outer coating, inner coating or inner powder coating, Which depends on customer’s various need.It is mainly used to prevent the side welding seam line from being exposed in air and rusting.The can body should be placed in induction drying oven to dry if it’s inner coating or inner powder coating.Afer drying, It will be fed to cooling device to make natural cooling.The cooled can body is then fed to the big square can combination machine, and the can body is in an upright state going through the uprighting conveyor. It is fed to the first automatic side welding seam indexing station by the clamps.The second station is square expanding.When the can body is in position, on the can body lifting tray which is controlled by a servo motor, and the can body is sent by this lifting tray to the square expanding mold to make square expanding.The third station is to make panel and corner embossing. When the can body is in position, on the can body lifting tray which is controlled by a servo motor, and the can body is sent by this lifting tray to the make panle and corner embossing at a time.The fourth station is top flanging, the fifth station is bottom flanging.The bottom flanging: the can will be sent to the bottom flanging mold lying on the upper part of the machine by lifting tray to make it. The top flanging:the upper cylinder will press the can body to the position of top flanging mold to make it. Both the top and bottom can body flanging are each driven by four cylinders. The sixth station is automatic lid detecting and feeding and seaming.After the above six procedures, the can will be reversed up and down by reversing device,and then make top seaming,this process is the same as the bottom seaming process.Lastly,the finished can is fed by conveyor to automatic leak tester station.After accurate air source inspection, unqualified products are detected and pushed to a fixed area, and qualified products will come to the packaging workbench for the final packaging process.

I Factory workshop preparation:

Area: At least 40 meters long by 10 meters wide, totaling 400 square meters

Flow rate: 2400 liters per minute.

Pressure requirement: 0.4-0.8 Mpa

Number of workers:4-5 people

II Preparation of production materials

1、Top lid, bottom lid, earpiece

① You can directly purchase top lids, bottom lids, and earpieces. In China, there are many specialized lid manufacturing factories that offer various specifications to choose from. If you have specific size requirements, you can request the lid factory to create custom molds for production. Once the production quantity reaches a certain threshold, the cost of mold fabrication is often waived or included for free.

② You can purchase equipment to produce top lids, bottom lids, and earpieces on your own. For more information about the relevant equipment, please click on the following link to learn more.

2、Can body material of printed tinplate

① You can directly purchase can body materials. In China, there are many professional printing tinplate factories that can customize can body materials according to your requirements.

② You can purchase tin printing equipment to conduct the printing on tinplate on your own. For more information about the relevant equipment, please click on the following link to learn more.

③ You can purchase the Double-side Glue Adhesive Film Laminating Line and process the tinplate yourself. If you would like to learn more about the relevant equipment, please click the link for more information.

3. Copper wire, adhesive, powder, iron wire, plastic glue plug.

These materials can be directly purchased worldwide.

Advantages: the whole production line adopts automatic computer programming control system, fully realizing the full automatic assembly line work.Only 1-2 workers are needed to complete the operation of the entire production line.The whole production line has fast production speed, high production efficiency, automatic fault detection system and low rejection rate.

Disadvantages: compared to semi-automatic production line, the initial investment capital is larger. For the start-up enterprises,It is recommended to use semi-automatic production line with less capital in.

ISHIN machines: all stations of the whole production line are processed with high hardness and imported wear-resistant materials. The imported guide rail and profile are combined with precise coordination of servo motor to ensure a fast conveying system. Eight-wheel can sealing machine head, The sealing quality is stable and fast .At the same time, the sealing machine head adopts special design, which has the characteristics of low noise and high efficiency.

Counterparts machines: most of the production line is made of domestic materials, common profile and domestic guide rail, combined with stepping motor,Which will be in some lack of stability and accuracy.Can sealing machine head only has four rollers, quality and speed will have a certain impact .At the same time the machine head adopts the old design, the production noise is bigger.

This production line is suitable for the production of square metal cans used in food, medicine, chemical, paint, edible oil and other industries.It can also be used in food can, paint can, edible oil can, paint can, lubricating oil can, etc.

Applicable to countries or regions where labor is difficult, unstable, or highly paid. Examples: Malaysia, Indonesia, Philippines, Vietnam, Thailand, India, dubai, Brazil, venezuela, etc.

Applicable to countries or regions with high output and high product quality.For example: Saudi Arabia, dubai, Russia, Canada, South Korea, Turkey, Europe, the United States and so on.
