When joining plastics it is best to opt for plastic welding as this allows for a strong and reliable joints to be made. There are well designed hot air tools and machines that have been developed to make plastic welding an easy task no matter what the application is.
There are a few ways in which plastics can be joined together, including chemical bonding through the use of solvents, and mechanical joining which uses screws and snap fits to make a joint. Although both of these methods will create joints between structures, they do not offer the strength achieved through plastic welding that creates a molecular bond that results in a strong, reliable joint that will not deteriorate in quality over time. Plastic welding is also relatively straight forward to complete once you have the right tools or machines; and it can be used on a huge range of plastics too.
Seeing as plastic is one of the most heavily used materials around the world, plastic welding serves an enormous range of functions. It can be used to join PVC-coated fabrics to make banners, tarpaulin, waterproof covers, shower curtains and similar structures. Plastic welding can also be used for consumer products such as bowls and cups, electrical items, toys, juice boxes and a huge amount of other items that are used every single day. Another common application for welding plastics is to create medical supplies and testing equipment, such as surgical instruments and tubing. All of these applications use hot air to join the structures together, and this involves pressing, heating and cooling stages that can be straightforward to carry out.
Plastic welding requires hot air tools to complete the job, and there are a number of tools that are available to use. Hot air guns are ideal for thinner plastics and these are an easy to use hand tool, whereas thicker plastics will require an extrusion gun to create a strong enough joint. There are then specialist machines for certain applications, a vinyl floor welding automatic machine being an example of one. It is important that tools and machines of the highest quality are used when plastic welding, which means using trusted companies, such as Leister. When top quality tools and machines are used it will allow for precision and the tools will not let you down. The top companies will also carry a wide range of tools and machines, so you can find everything you need for plastic welding.
Hot air tools are the best and most reliable way to join plastic structures together, and thanks to well designed tools and machines, it can also be easy to complete tasks. Other methods such as chemical and mechanical bonds can work, but they do not offer the strength that you get through plastic welding. This could be for manufacturing toys, welding roof membranes, and creating a banner, among a huge number of other applications.
