Levapack Screw Capping Machines
In any packaging system may it be in the food or non-food industry, especially lines that are handling liquid products, having a reliable capping machine is essential. A capping machine ensures that after the containers pass through the filling station, they will be securely sealed and ready for the next step of the manufacturing chain - delivery.
Screw capping machines are one of the most popular types of capping machines when it comes to packaging liquid products and other harmful substances aside from solid ones. To avoid leakage on the packaged liquid containers, you will not only need a reliable screw capper equipment. But also one that meets your packaging line’s actual needs and requirements which is made possible through customization of your very own screw capper machine.

What is a Screw Capping Machine?
A screw capping machine is used to tightly seal containers with different dimensions having screw-on type closures in an ergonomic design. Compared to manually placing the screw caps on the containers by hand, using a screw capper machine eliminates injuries and strains to the workers. The operator only needs to load the lids and containers into the machine and it will do the rest of the job.
Types of Screw-on Closures
Screw-on lid closures are among the commonly used closure types in various packaging industries. They are generally caps that are threaded which require torque before they can be tightened onto different container types. The screw-on type bottle containers that you are probably most familiar with are the ones used in soft drinks and bottled water.
However, there are other screw cap variations - from the standard flat cap to trigger sprayers. Below are the most common types of screw-on closures you will find in groceries.
#1 Flat Screw-on Closures
These screw-on cap closures have flat tops and you can usually find these on soft drinks and bottled water.
#2 Sports Closures
Sports closures are similar to flat tops but without the flat tops. They have extended tops instead. To open these types of caps, you have to pull up or twist the sports lid, often requiring you to squeeze it, which allows a controlled flow of the product from the container. Sports caps are used in a few bottled water and energy drinks like Gatorade.
#3 Press Top Closures
Press top closures are screw caps having one pressable side which when pressed will pop the lid on the other side. They are common in shampoos and body washes.
#4 Trigger Sprayers
This is the most unique type of screw-on closures found in various household products such as glass cleaners. They include a sprayer and a straw which allows it to shoot a product mist from the cap. Spindle cappers are usually used to cap these types of screw-on closures.
#5 Anti-Theft Closures
Anti-theft closures are tamper-evident screw caps that possess tear-off rings located at either the cap’s bottom or on its sidewall. The rings separate when you open the container for the first time.
Types of a Screw Capper Equipment Based on the
Capping Device Used
Basically, there are two common types of screw capping machines: chuck and spindle screw capping machines.
Screw Chuck Capping Machines
A screw chuck capping equipment uses a chuck or a capping head and is sometimes installed with a rubber insert used to lower the closures and apply torque on it to produce a tight seal. These machines are mostly in semi-automatic designs.
Our LPE-RVS040 Rotary Screw Capping Machine for Glass Bottle and LPE-RVS040 Rotary Vacuum Screw Capping Machine for Glass Can are screw chuck capping machines but ours are fully automatic ones.
Screw Spindle Capping Machines
Instead of using a chuck head, a screw spindle capping equipment uses a spinning disk or wheel for tightening the caps and are usually designed as automatic machines. When integrated with a conveyor system, automatic spindle capping machines allow auto-feeding of lids for a continuous capping process. Our LPE-SCM008 Screw Capping Machine is of this type of screw capper machine.
Types of Screw Capper Machines Based on Mode
Whatever production speed your packaging lines are designed for, they will all require assistance to properly cap the containers. In fact, the goal of incorporating a capping machine in your packaging lines is not only for increasing the production speed. Bottle capping machines allow for reliable and consistent seals to prevent loose caps, overly tightened caps, crooked caps, and product waste caused by spills.
Fully Automatic Screw Capping Machines
Fully automatic screw capping machines are designed for the provision of continuous container capping in your packaging line. These types of machines come with conveyor and delivery systems for the lids. For instance, a cap elevator or a vibratory bowl. Automatic screw capping machines are controlled using a touch screen control panel and various levers and/or finger knobs that are necessary for the machine.
Furthermore, the packaging line operator is responsible for the provision of bulk cap quantities to the machine’s cap delivery system. Once the screw can capper machine is completely set up with the caps provided, the operator’s remaining job is to:
- Keep watch of the machine while it does its job.
- Always ensure the availability of caps in the cap delivery system.
Semi-Automatic Screw Capping Machines
Semi-automatic screw capping machines come in various designs. They can be handheld, tabletop machines, or semi-automatic screw cappers built on portable frames. They can handle various cap sizes and containers like the fully-automatic screw can cappers. The major difference is that semi-automatic screw cappers require manual placement of the lids onto the bottles before the machine applies the necessary torque to tighten the lids.
Furthermore, semi-automatic screw cappers built on portable frames can be moved from one place to another easily and thus are ideal for low production requirements. For tabletop semi-automatic screw cappers, they are built with small sizes but placed in a permanent location, unlike the movable portable frames.
Why Use a Screw Capping Machine?
Aside from increasing the speed of your packaging lines, screw can capping machines ensure that proper hygiene is maintained on the caps. This avoids product contamination which is not prevented when the capping process is manually handled. Furthermore, screw cappers save your operators the hassle of manually screwing the lids into the bottles themselves.
How Can Screw Capper Machines Benefit Your
Screw capper machines save time and streamline your packaging lines for faster bulk productions. For example, you can rely on the machine to do all of your manual work while producing more uniform and consistent results compared to capping by hand. Aside from this, you can prevent costly spills caused by manual capping. So not only can you save time but also money because automated packaging lines decrease your operating costs and the possibility of defective capped containers.

LPE-SCM008 Screw Capping Machine
Our LPE-SCM008 screw capping machine model is installed with four heads (total of eight spindle disks) to tightly torque threaded closures at high speeds for more efficient capping process. It has a touch screen interface for adjusting the capping operation parameters and effectively prevents damages to anti-theft closures when capping. Furthermore, this machine has an adjustable spindle wheel to accommodate various bottle sizes.
LPE-RVS040 Rotary Vacuum Screw Capping Machine for Glass Can
Similar to our LPE-RVS040 rotary screw capping equipment, our LPE-RVS040 rotary vacuum screw capper machine is equipped with a rotary clincher and a rotary cap feeder but the clincher has six stations for accurate capping. You can adjust the vacuum and cap torque settings to your desired standards. Moreover, it can handle various cap dimensions and bottle types.
Components of a Can Screw Capper Machine
Since LPE’s screw can capper machines have fully automatic designs, the components listed below are of a fully automatic screw capping equipment.
#1 Chuck Head
In screw chuck capper machines, a specialized clamp called a chuck head is used to hold the container being capped. The chuck head applies torque on the lid to create a seal.
#2 Spindle Disks
For screw spindle capper machines, they use sets of spindle disks (usually 3-4 sets) that spin the caps down onto the container as the container moves to the capping station. Our LPE-SCM008 Screw Capping Machine has 4 spindle wheel sets.
#3 Cap/Lid Sorter and Feeder
The lid sorter sorts the right caps to be fed into the machine and its design will depend on the cap geometry the machine handles. On the other hand, the lid feeder of the screw capper equipment can either be a cap elevator or a vibratory bowl.
#4 Cap Chute
The screw capper equipment requires the cap chute to hold the lids in place. It is responsible for placing the lids on the top of each bottle that passes through the spindles or chuck.
#5 Conveyor Belts
The screw capper’s conveyor belts are vital parts of an automatic screw capper equipment. The machine will depend on these for the transportation of the containers towards the capping zone and to other parts of the machine. They are continuously moving and can either be made from metal or rubber materials. Moreover, they are essential in firmly guarding the containers during the capping process to prevent them from going off the capping line.
#6 Drives, Gear Boxes, and Motors
These parts are also called the driving engine of your screw capper equipment. By working together, they help drive the other components of the machine for a smooth capping operation. You can set the speed of their movement on your capper equipment’s control panel.
The pulleys also play a vital role in the transport process in an automatic screw capper machine. They are connected to the belts and gears and assist in moving different parts of the machine. Their sizes are varied depending on your screw capping equipment’s design.
#8 Shafts and Sprockets
These two work together in assisting the machine during the transmission of a rotary force to the shafts. Just like pulleys, motors, gearboxes, and drives, the shafts and sprockets are important components of the machine that are used to drive the capping process.
How Screw Can Capping Machines Work
Whether a chuck or a spindle capping machine in semi-automatic or fully automatic operation modes, the working principle is similar for both machines except for the device used by each to tighten the lids onto the containers. The basic idea is to apply torque on the screw-on closures to create a seal. Below is a step-by-step guide on the screw capping process.
Step 1. Lid Feeding and Sorting
Automatic lid feeding and sorting only takes place on fully-automatic chuck and spindle screw capping machines. The operator feeds the machine with bulk quantities of screw-on closures through the cap-feeding system. The caps are led into the cap sorter which removes the disoriented caps from the line and directs the properly oriented ones to the cap chute.
Step 2. Placement of Lids Onto the Containers
Fully Automatic Screw Capping Machine
The oriented closures fall down the cap chute by gravity. When a container is detected, the chute releases a cap placing it exactly on top of the current container. The container will continuously move via the conveyor belt before it proceeds to the capping station.
SemiAutomatic Screw Capping Machine
In this machine operation mode, the operator needs to place the lids onto the containers manually before feeding the cap-container combination into the screw capping machine.
Step 3. Screw-Cap Tightening
Fully Automatic Screw Capping Machine
Fully Automatic Spindle Screw Capping Machine
For inline fully automatic screw capper machines such as spindle screw cappers, the cap-container combination proceeds to the capping station in a linear path. As the combination passes through the sets of spindle wheels/disks, the spindles apply the required torque on the lids to create a seal. Our LPE-SCM008 Screw Capping Machine uses four sets of spindles to tighten the lids.
Moreover, to make the capping reliable and consistent, the machine uses cap stabilizers and side gripper belts to hold the combination in place as it moves through the spindle wheels. In fully automatic screw cappers, the capping process runs continuously without the containers stopping for cap placement, indexing, or any other reason.
Fully Automatic Chuck Screw Capping Machine
Fully automatic chuck screw cappers are popular in rotary layouts. They use a rotary or a star wheel for the capping process which means that the process will not run continuously like in the spindle capper machine. Each cap-container combination is directed by the conveyor belt into one of the star wheel’s pockets. The wheel rotates and puts the combination below the chuck head for tightening.
The chuck head will then descend onto the cap-container combination and applies torque on it to create a reliable seal. After the lid is tightened, the star wheel rotates again and directs the sealed product to the release point.
Semi-Automatic Screw Capping Machine
The tightening process for semi-automatic screw cappers is similar to the fully automatic ones except that instead of the process starting automatically, the operator needs to manually place the cap-container combination into the screw capper. Depending on the design of the semi-automatic screw cappers, either a footswitch or a hand switch is used to activate the capping process.
Step 4. End of the Process
Fully Automatic Screw Capping Machine
The capped containers automatically proceed to the end of the capping line and are now ready for the next steps of the packaging line.
Semi-Automatic Screw Capping Machine
Since the capping process is not fully automatic, each capping cycle is only done in a few containers. For semi-automatic chuck cappers, the process is usually done per cap-container combination so the operator needs to repeat the process for each container. While for semi-automatic spindle cappers, the only thing the operator needs to do is feed the machine with capped containers manually and it will do the rest.
