Thermoplastics are being used more and more for storing a huge range of liquids or for manufacturing what can be complex process equipment, such as fans or pumps. Plastic's resistance to corrosion and material strength are usually the reasons why it is used. In addition, the price of a part made from plastic is lower than that of one made from metallic materials. Leister offers a full range of hand extruders, hand welding tools with integrated blowers, hand tools operated with an external fan (together with matching blowers), and a variety of nozzles for this application area.
