What an induction sealing machine is?
An induction sealing machine is one type of electronic equipment that seals the caps of non-metallic such as glass, plastic, etc., containers using heating technology. It basically presses down the cap using heat and seals the mouth of the container. It works on Polyvinyl Chloride; Polyester, Polythene, Glass etc., made containers.
What benefits an induction cap sealer provides
Though induction foil sealers are affordable, is it solely the reason why these machines are so widely used in several manufacturing companies? Obviously, no. The followings are a few reasons these machines are more famous than most high-tech machines and why you should prefer induction sealing machines over other similar ones:
Superior leak prevention quality
The induction sealing machine has one of the best leak-preventing sealing procedures. The even layout of the machine ensures this quality.
Tamper-resistance
The sealed caps using induction sealing machines are proven to have the most durability and tamper-resistance property.
Preservation quality
The leakage-free seals guarantee the preservation quality of the seals using these machines. This quality is very useful for preserving medicines and other such products.
High production rate
The machine has a very fast production rate due to the usage of high-quality electromagnetic induction.
Types of induction sealing machines
You must know all the types of induction sealing machines to know what type will be the most beneficial to you.
Manual induction sealing machine
This type of machine is operated by hands and can not work for continuous hours. It also has a relatively slower rate of sealing speed. These machines are more suitable for home use and small personal businesses. These machines are smaller in sizes and weigh less. So it is portable.
Fully automatic induction sealing machines
The automatic ones use the electromagnetic field for operating. The machines seals, caps and then organize the containers on their own. These machines can also work for hours continuously. This type of machine is the best for large-scale production where the machine has to work for hours without any break. These machines have a very high rate of sealing and capping. It mainly operates automatically by an electromagnetic field.
Semi-automatic induction sealing machines
Here the sealing and capping are done on their own, but the container needs to be put in place and be removed after sealing by the worker. Though the machines do well in making airtight seals, it works very slowly for large-scale production.
Component of sealing machines and how it works
Though the induction sealing machines have various designs and parts for different types, the main two components, the power supply and the sealing head, are the same. Without these two parts, the machine can never work.The sealing head has a plastic-covered coiled conductor inside that emits an electromagnetic current once the main power supply heats up the inductive coil. When a container fitted with an induction lined cap passes through this current, the inner-seal foil gets heated, melting down the foil’s outer polymer coating, resulting in bonds with the container’s mouth. You must check them very closely to understand the work efficiency and quality of the machine.
- Main power supply
The power rating of a sealer is very important as it indicates the machine’s work efficiency and suitability for your use. It also determines the production rate of the machine. The small or manual ones do not need a very high-power supply. 1KW is enough for them. But for the continuous or automatic ones need nearly 6KW or more power rating to work properly.
- Sealing head
Check the type and size of the sealing head. It may be small or large. Check what type of sealing the machine can perform too. Also, check the coil’s material and quality in the sealing head as it ensures the quality of sealing. A two-piece liner has an extra layer of wax and pulpboard that melts down during the sealing process and remains within the pulpboard to make resealing better once the foil liner is pulled out. Plastic containers containing plastic thread caps are the easiest to perform sealing on, while glass and metal are the toughest.
What to look for in induction sealing machines
Follow and check these guides to know the product better and find out its compatibility with your choices and requirements.
The durability of the machines
Check for how long the machine can work continuously. Also, check if there is any heating issue with the working hours. Ask the average lifetime of the machine.
Tamper-evidence quality
Check if the seal from the machine gives away its tamper evidence. Tamper evident seals mean the marks on the seal that implies the seal has been opened or tampered with. It will help your customer know the seal’s condition. Buy a machine that has tamper-evident seals.
Work efficiency
Check how many seals the machine can seal within an hour. Check the power supply and determine the speed of sealing. Check the voltage capacity too.
Trends to follow
The following qualities in sealing machines are highly preferred by consumers these days. You may buy one with them:
Small but efficient machines
Induction sealers are no longer a huge sized machine these days. The size has gotten smaller, with an increase in work efficiency. The small size of the machine has made it portable and more desirable.
Anti-counterfeiting property
A lot of seals can be duplicated now, so machines with anti-counterfeiting quality are very high in demand now. It is mainly desired by large scale manufacturing companies that have their original products.
Tamper-evident seals
Seals can be easily removed these days. A lot of fake products are sold by tampering with the seals, which lowers the quality standard. The tamper-evident seals can reduce these events by showing the evidence of tampers.
User-friendly seals
These seals are very famous as it takes less effort to remove them thanks to an extra tab. Though these are high prices now, it is expected to come down in the near future.
Conclusion
Read the article carefully and understand what qualities need to be checked before buying an induction sealing machine. Be wise and choose only the best machines for yourself to get the best results.
