A 3-piece can production line combines several processes to turn tinplate sheets into finished metal cans. Stable material handling and automatic conveying are important because every process needs to work together continuously.
Baoli specializes in auxiliary equipment and automation systems for 3-piece can production lines. Instead of manufacturing every main can-making machine, we focus on the equipment that connects different processes and helps cans move smoothly through the production line.
Our equipment covers sheet feeding, can body handling, drying and cooling, can conveying, lid feeding, palletizing and end-of-line packaging.
Depending on the factory layout and production requirements, Baoli equipment can be supplied as individual machines or integrated into an automated can-handling system.

A typical 3-piece can production process starts with tinplate sheets. The sheets are processed into can bodies, welded and formed before moving through subsequent handling and packaging processes.
A simplified production flow is:
Tinplate Sheet → Sheet Feeding → Printing / Coating → Drying → Can Body Forming → Welding → Can Handling → Conveying → Inspection → Palletizing → Strapping → Stretch Wrapping
The exact process and equipment configuration depend on the type of can, production capacity and customer's existing machinery.
For this reason, auxiliary automation equipment plays an important role in connecting different sections of the production line.

Automatic sheet feeding equipment transfers tinplate sheets from the upstream process to the next production stage.
Baoli provides sheet handling and transfer solutions for applications where sheets need to be collected, aligned and transferred automatically.
Depending on the application, the system can use mechanical transfer or robotic handling.
Typical equipment includes:
Automatic sheet feeding systems
Sheet collecting equipment
Sheet transfer systems
Robotic sheet handling systems
Can body blank sheet feeding equipment
The feeding system can be customized according to sheet dimensions, production speed and the layout of the existing line.
Drying and curing are important processes in many tinplate can manufacturing applications.
Baoli supplies drying and curing equipment designed to work with automatic can production and handling systems.
The equipment can be integrated with upstream and downstream conveyors so that can bodies can move continuously through the production process.
Typical applications include:
Can drying
Coating curing
Can body heating
Tinplate can production line drying
Can conveying is one of the key areas of Baoli's automation solutions.
After can bodies are formed or welded, they need to be transferred between different machines at a stable speed and in the correct direction.
Baoli provides different types of can conveyors and can handling equipment according to the production line requirements.
Available solutions include:
Straight conveyors
Turning conveyors
Inclined conveyors
Vertical conveyors
Magnetic conveyors
Chain conveyors
Mesh conveyors
Belt conveyors
S-type and Z-type elevators
Differential conveyors
Cooling conveyors
The conveyor system can be designed according to can diameter, can height, production speed and factory layout.
For existing factories, the conveyor can also be customized to connect with current production equipment.
Can orientation and accumulation may be required at different stages of the production process.
Baoli provides equipment such as can upenders, standers and rotary machines to change can orientation or adjust the flow of empty cans.
These machines help maintain a stable flow of cans between different processes and reduce manual handling.
For production lines that require automatic lid handling, Baoli provides automatic can lid feeding systems.
The system can automatically separate and feed lids into the required position, helping reduce manual feeding and improve the continuity of the production process.
Applications can include food cans, beverage cans and other metal container production lines.
Depending on the lid specification and production requirements, the system can be configured with different feeding and separation methods.
After the production and conveying processes, finished empty cans need to be collected and stacked for storage or transfer to the next process.
Baoli provides different automatic can palletizing solutions for empty tinplate cans.
Our palletizer range includes:
High-level can palletizer
Low-level can palletizer
Robotic can palletizer
Rotary can palletizer
Push-type can palletizer
The suitable palletizing system depends on production speed, can dimensions, pallet size, stacking pattern and available factory space.
For flexible applications, a robotic palletizercan be integrated with suitable industrial robot systems according to the project requirements.
For higher-output lines, high-level or other automatic palletizing configurations can be selected according to the required production capacity.
Palletizing is normally not the final step of an automated can-handling system.
After cans are stacked, the finished pallet can be transferred automatically to downstream packaging equipment.
A typical end-of-line process is:
Can Palletizer → Pallet Conveyor → Strapping Machine → Stretch Wrapping Machine
Baoli can provide equipment for different stages of this process, including:
Pallet conveyors transfer empty pallets to the palletizing position and move finished pallets to downstream equipment.
They can be designed as part of an integrated pallet handling system.
After palletizing, automatic strapping equipment can secure the palletized cans before wrapping or transportation.
The stretch wrapping machine automatically wraps the completed pallet with stretch film to provide additional stability and protection during storage and transportation.
Depending on the customer's packaging requirements, other end-of-line equipment can also be integrated into the system.
Baoli equipment can be used individually or combined into a complete material-handling and end-of-line automation system.
A typical solution may include:
Sheet Feeding → Can Handling → Drying → Conveying → Cooling → Can Orientation → Palletizing → Pallet Conveying → Strapping → Stretch Wrapping
This allows different production processes to be connected through automatic material handling instead of relying on manual transfer between machines.
For factories upgrading an existing line, Baoli can also design individual equipment around the customer's current machinery and available space.
Baoli auxiliary equipment can be used in different tinplate can manufacturing and handling applications, including:
3-piece food cans
Beverage cans
Tin cans
Tinplate containers
Metal cans
Industrial cans
Food packaging cans
Other suitable empty metal cans
The equipment configuration is selected according to the actual can dimensions and production requirements.
For example, the conveyor design for a small food can may be different from the handling system required for a larger industrial tinplate container.
Every can factory has a different production layout.
Baoli can customize equipment and automation solutions according to:
Can diameter
Can height
Tinplate sheet dimensions
Production speed
Existing machines
Factory layout
Conveyor direction
Pallet dimensions
Palletizing pattern
Available installation space
Automation requirements
The objective is not simply to supply individual machines, but to make sure that the equipment works smoothly with the customer's existing production process.
Baoli has focused on can-making automation and auxiliary equipment since its establishment in 2011, while the company's founder entered the can-making industry in 2003.
With experience in material handling and production-line automation, Baoli understands the practical challenges involved in connecting different sections of a can production line.
Our service can cover:
Solution Design → Equipment Manufacturing → Installation → Commissioning → Production Guidance → After-Sales Support
For overseas projects, remote technical support is also available, with on-site installation and commissioning arranged according to project requirements.
A 3-piece can production line may include sheet handling, printing or coating equipment, drying or curing equipment, can body forming and welding machines, conveying systems, inspection equipment, palletizers and end-of-line packaging equipment. The exact configuration depends on the can type and production process.
