Heat sealing machines are very valuable today. Instead of using tapes, glues, sewing or other intricate methods of bonding, many industries are now using the heat sealing cutting edge technology. When manufacturing products using polyester or nylon fabrics with thermoplastic coating such as tents, awnings, tarpaulins and many others, these machines are used to provide airtight and water tight seals on the seams. With plastic pouches or bags, you use heat and pressure to bind these sheets to have an insure seal.
Automated micro-processor band sealing machines are designed to seal various thermoplastic materials such as polyvinylchloride, polyurethane, polyethylene and polypropylene and other materials like ribbon, foil and nylon. The automated sealer can be adjusted as needed to different angles. The speed of the conveyor belt is adjustable to various types of thickness. The machine has a variety of features including a speed regulator fan, temperature control system, power switch, printing wheel, etc. They come in vertical or horizontal models which incorporate color printing, sealing, continuous transmission of products with clean and bright patterns, color selector and different technical specifications.
You can avail of them in manually operated models. For sealing of polypropylene or polyurethane bags from 20-200 microns, there is a range of heat sealing equipment which is available in table top to foot operated machines. There are simple hand or foot pedal sealers for home and small scale operations. They have sealing capabilities from 100mm to 700 mm. This is the most simple, affordable and proficient method.
For industrial and commercial applications, there is full range of automated line of sealing machines for sealing plastic bags, fabric coated fabrics and boxes, etc. depending on your needs and requirements.
For carton packaging of various types of products such as appliances, textile, general merchandise, pharmaceutical products and many more, there are a wide range of high speed and precision sealing machines which can accommodate different sizes, specifications and shapes. You can opt for the pneumatically operated L-sealers for higher production output. These easy to install machines are very much in demand because of its ease in operation, superior performance and durability.
There are two basic types of sealing machine. You have the rotary heat sealer or the dialectric or radio frequency sealer. The dialectric or radio frequency sealing technique has been around for many years. In this process, a timed pulse of radio frequency energy heats the fabric between the die and base plate to create the fusion and bonding.
The rotary heat sealing is the more popular and widely used sealing technology today by many industries. It does not need any die or tooling aside from the need for appropriate nozzle and drive wheel widths. It is much faster to seal for many products than the dialectric sealing. Its speed can produce up to 6 meters or 20 feet per minute for a variety of seam types and patterns. To realize the full potentials of this technique, you have to allow sufficient time for the operator to develop the skills needed to operate this system. You can allow your operator to undergo in-depth training when it comes to the rotary wedge and hot air welding techniques.
In choosing your top of the line automatic heat sealing machines, you have to look for a supplier who has an enviable track record of durable and reliable machines. They have to render excellent training to your operators. You have to be sure that they provide sufficient warranty, adequate technical support and sufficient parts when you need them. Heat sealing machines can improve your business operations if you invest and install the right ones!
