Welding plastics is done by bringing them up to the specific weld temperature (viscous flow), joining them under pressure and allowing them to cool down slowly.
There are many types of welders on the market today. From hand-held "stick" welders, injection welders and high output extrusion welders to sheet and pipe fusion systems, selecting the right welding equipment can be a challenge. Knowing the application is the first step in determining your equipment needs. There is a suitable solution for virtually all plastic welding requirements.
There are also numerous plastic materials and blends on the market today. It is essential to know what material you are joining to achieve a strong weld. A testing lab can easily identify most common plastic materials. There are also several tests you can perform on your own, the most accurate being the burn test.
Every plastic material reacts differently when it burns. For this test, you must know the different behaviors and smells of plastic. If possible, keep samples of plastic materials that you already know. You can compare these samples with unknown plastics.
