A can sealing machine is a device designed to seal plastic or glass bottles by securely affixing lids to their openings. Its working principle involves pressing the lid onto the mouth of the container, creating a tight seal between the two surfaces, and ensuring an effective closure.

Can sealing machines can be divided into many types according to the sealing method and function. Common ones include manual can sealing machines, semi-automatic can sealing machines, fully automatic can sealing machines, etc. 

Besides the common name method, that there are other types calling of can sealing machine. Let’s explore of together to find out how many types of can sealer and choose the most suitable machine for your business.

1. Manual Can Sealing Machine  

The manual can sealing machine is operated by hand, offering a simple, convenient, and cost-effective solution for sealing cans. It's ideal for small batches and low-speed production, making it popular in homes, schools, and similar environments. Depending on the sealing mechanism, there are two main types: desktop manual can sealing machines and foot-operated manual can sealing machines.

2. Semi-Automatic Can Sealing Machine

A semi-automatic can sealing machine combines automation with some manual adjustments. It automatically handles tasks like feeding, capping, and sealing, but still requires the operator to adjust certain settings. These machines are typically used by small businesses. Variants of the semi-automatic model include hydraulic and pneumatic types, which differ in their sealing mechanisms.

3. Fully Automatic Can Sealing Machine

The fully automatic can sealing machine is designed for high-volume, high-speed production lines. It automates the entire process—feeding, capping, sealing, and even printing and coding. This type is generally used by large-scale enterprises. There are different styles available based on the sealing method, such as rotary, push-type, and barrel-type fully automatic can sealing machines.

The naming rules of can sealing machines usually include the following aspects:

1. According to the sealing method: such as rotary can sealing machine, capping can sealing machine, etc.

The rotary capping machine is also called capping machine, capping machine or locking machine. It is a device used to tighten and loosen the bottle caps of plastic bottles and glass bottles (molded bottles or tube bottles) after packaging. The capping machine is generally used for aluminum caps or aluminum-plastic cap rolling and sealing equipment after the glass bottles (molded bottles or tube bottles) of antibiotic powder injections are packed.

The small capping machine is a desktop three-knife cyclone capping machine with a stainless steel appearance and safe and convenient operation. When working, the bottle being rolled does not rotate, and three cyclone knives are evenly distributed at 120° to rotate and roll the cap to seal. The knife handle is designed as a spring structure. The distance between the three knives can be fine-tuned, with strong adaptability and high capping yield. This machine is an ideal choice for troops, hospitals, laboratories, and small pharmaceutical factories.

2. According to the characteristics of the sealed bottle: such as round can sealing machine, flat can sealing machine, etc.

‌Round can sealer‌ is a machine specially used to seal round cans, mainly used to seal various round canned containers, such as cans, Sprite cans, etc. This machine is widely used in food, beverage, chemical and other industries. ‌

Working principle and structural characteristics ​The working principle of round can sealer mainly includes two methods: heating sealing and compressed air or vacuum sealing. ‌The heat sealer heats the sealing material to melt it and fit it to the can mouth to achieve the purpose of sealing; while the cold sealer uses compressed air or vacuum to make the sealing material form a seal at the can mouth. ‌

In addition, some round can sealers also combine the composite technology of heat sealing and cold sealing to provide a more solid sealing effect. ‌

Application scenarios and industry applications ​Round can sealers are widely used in food, beverage and chemical industries. In the food industry, it is used to seal various beverage cans and food cans; in the beverage industry, it is used to produce cans, carbonated beverage cans, etc.; in the chemical industry, it is used to seal various chemical containers.

Due to its high efficiency and stable performance, round can sealing machines play an important role in these industries.

3. According to the function of the sealing machine: such as inkjet can sealing machine, label can sealing machine, etc.

‌Inkjet can sealing machine‌ is a device that combines inkjet technology and can sealing function. It is mainly used to print production date, batch number and other information on metal containers such as cans, and complete the can sealing operation. This kind of equipment is usually installed on the production line and can work stably in a high-speed production environment to ensure that each product can be accurately printed and effectively sealed.

Functions and application scenarios of inkjet can sealing machine

The main functions of inkjet can sealing machine include:

Inkjet: Print production date, batch number, shelf life and other information on metal containers such as cans.

Can sealing: After completing the inkjet, the sealing operation is automatically performed to ensure that the container is sealed.

This equipment is widely used in production lines in the beverage and food industries, especially in high-speed production environments. It can ensure that the label of each product is clear and accurate, and the seal is firm to prevent the contents from leaking out.

4. According to the applicable industry of the sealing machine: such as food canning machine, chemical canning machine, etc. Food canning machine is a kind of equipment specially used in the food packaging industry. It is mainly used to seal metal cans, paper cans, plastic cans, etc. to ensure the sealing and shelf life of food.

Chemical canning machine is a mechanical equipment specially used to seal chemical product containers. Its main function is to achieve accurate sealing of various types of cans through the combination of heating, cooling and mechanical systems.

Chemical canning machine plays an important role in the chemical industry and can ensure the sealing and safety of chemical products.

In short, the naming of canning machine is based on comprehensive considerations of sealing methods, characteristics of sealed bottles, functions of sealing machines, and applicable industries. If you would like to know more information of can sealing machine, feel free to contact Tengzhuo packing, our sales would provide the professional suggestion to you.
