What is an Automatic Can Sealing Machine

As automatic can seamer machines are mostly used in sealing tin-plated can lids, they are also known as automatic tin can sealing, sealer, or seamer machines. They are used to fully automate the hermetic sealing of various containers which can either be a jar, pot, glass, plastic, PET, aluminum, tin, paperboard, and others.

Automatic can seamers are common in big industries with large production requirements. They need these machines to streamline their packaging process for more efficient production and higher savings in operating expenses. Unlike a semi-automatic can sealing equipment that uses a footswitch or push-button for operation, fully automatic seaming machines do not need any human intervention.

Moreover, auto can seamer machines can be installed with other options like nozzles for product filling, smart weighing systems, nitrogen spraying, and others.

Major Components of an
Automatic Can Sealing Machine

An auto can seamer equipment has the following major components:

#1 Seaming Rollers

The seaming rollers interconnect the lid to the can body and tighten the seam. LPE’s Fully Auto Nitrogen Filling Vacuum Sealing Machine has two seaming rollers while our Servo Fixed Speed Sealing Machine and High Volume Fully Auto Round Can Sealing Machine each have four rollers.

#2 Seamer Head (Chuck)

This component tightly holds the lid and supports it from the pressure exerted by the rollers. The chuck’s dimensions can be customized based on the round can’s diameter.

#3 Seamer Turntable (Base Plate)

The seamer turn-table is a spring-loaded disc that gives support to the can body being sealed and it spins freely. LPE’s Servo Fixed Speed Sealing Machine and High Volume Fully Auto Round Can Sealing Machine use a turntable.

#4 Lifting Tray

Our Servo Fixed Speed Sealing Machine and High Volume Fully Auto Round Can Sealing Machine use lifting trays to lift the containers for sealing.

#5 Sealing Chamber

LPE’s Fully Auto Nitrogen Filling Vacuum Sealing Machine performs the whole sealing process inside a sealed chamber.

#6 Vacuum Room

Our Fully Auto Nitrogen Filling Vacuum Sealing Machine has a vacuum room which removes the oxygen from the containers under vacuum pressure.

#7 PLC Control Panel

This panel is where you set the settings of the sealing operation. LPE’s Servo Fixed Speed Sealing Machine contains control buttons while our High Volume Fully Auto Round Can Sealing Machine has an integrated man-machine interface.

How Automatic Can Sealing Machines Work

Automatic Can Sealing Machine Designs

There are two basic auto can sealing machine designs - rotary and non-rotary.

Rotary Machine Design

In a rotary auto can sealing equipment, the machine spins the container while it performs the sealing process. They are used mainly in big productions in the food industry. Our Fully Auto Nitrogen Filling Vacuum Sealing Machines and High Volume Fully Auto Round Can Sealing Machines have this kind of machine design.

Non-Rotary Machine Design

Contrastingly, a non-rotary auto can seaming equipment keeps the container stationary in the sealing process which avoids container damages and spilling of liquid products inside. These are ideal in beverage industries. LPE’s Servo Fixed Speed Sealing Machine has a non-rotary machine design.

The Can Seaming Process

Can bodies have flanges with a curl at its end which when processed in the can seamer machine, the curl is interlocked with a lid’s flange curls to create a double seam.

The can seaming process starts by feeding the containers to the can seamer via the conveyor and are indexed automatically to the sealing area. For our Fully Auto Nitrogen Filling Vacuum Sealing Machine, the containers go straight to the sealing area. Whereas in our Servo Fixed Speed Sealing Machine and High Volume Fully Auto Round Can Sealing Machine, the containers are delivered below the seamer chuck via a turntable.

Then the can is lifted up for lid attachment where a three-stage sealing process happens as discussed in the following sections.

Stage 1. Compression

In this stage, a force is exerted to hold the can against the seaming chuck and places the lid into it then feeds the lid-container combination to the first roller for the double seaming process. For the vacuum sealing machine, the oxygen inside the container is first vacuumed and nitrogen is flushed into it before the lid is placed.

Stage 2. First Roller Operation

This stage is the most critical one for ensuring the integrity of the double seam to avoid wrinkles and leaks. The first roller comes in and folds the lid’s curl into the can’s flange forming a hook which is monitored to guarantee the seam’s integrity in various conditions. The fold should not be too loose or too tight because you can’t correct this later. After this stage, the seal is not yet hermetic and needs a second roller operation.

Stage 3. Second Roller Operation

Since the initial seam is still a loose one, the second roller operation stage irons it out to make sure that the sealing is tight by compressing the interlocked hooks of the lid-container combination. Then the machine squeezes a sealing substance into the open spaces between the seam to complete the hermetic seal. This sealing substance makes sure that no leaks and contamination will happen by reinforcing the seam.

The shape of the seam depends on the shape of the first and second rollers and the following:

  • The relative position and distance of each roller
  • Lifter pressure
  • Lifter height
  • Advantages

    #1 Overload Protection System

    Our automatic can seamer equipment comes with an overload protection system to avoid damages caused by machine overload. It allows your seamer machines to have longer service lives and saves on maintenance costs.

    #2 Fast and Tight Seaming

    We have automatic can seaming machines with four rollers to ensure a consistent and leak-proof seam through very tight sealing. They can seal up to a maximum of fifty cans per minute.

    #3 Durability

    The machine components are made from #304 stainless steel for better mechanical rigidity and to prevent rusting for more durable seaming machine.
