Extruder PW3


Product Image

It is used for welding of polypropylene and polyethylene plastics with the help of an additional material. The device consists of the following parts: drive unit, melting chamber with screw and welding wire feed, hot air blower, control electronics. The welding principle is similar to a hot-air gun welding, the material we first weld is preheated by a hot air blower, and then a certain amount of melt is applied to the desired shape by a Teflon welding shoe. The device is fully electronically controlled by two P.I.D. high-level regulators. One controls the temperature of the melting chamber and the other the temperature of the preheating air. The welding device has the following advantages: Reduced workload, human factor is minimized so that 100% welding does not require multiple brazing of larger products, the drive can not be started when the unit is heated up, there is no need for additional equipment, external air supply and some other blower, as it is already part of the device. Only single-phase mains voltage 230V with 16A fuse is required for operation. As an additional welding material, welding wire of the same material as welded plastic is used. The wire has a diameter of 4mm and the power of the welder using a wire of this diameter is 3 Kg / h, which is also sufficient for large-scale products. This wire is fully melted and receives a new shape using a teflon shoe, which is a part of the delivery and can be customized according to customer requirements.
