The principle of infrared pre heating welding:
Infrared pre heating welding is a non-contact heating method used to radiate and heat plastic workpieces. It is based on a shortwave infrared generator and is characterized by fast start-up and closure. The surfaces of two parts to be welded can be quickly heated under infrared radiation, and then fused together after vibration and friction, achieving high welding strength.
Regarding the aesthetic issues of waste residue and overflow generated by vibration welding of car lights:
The waste generated during vibration is treated by pre heating the welding lines of the face shield and bottom shell using infrared technology.
1. The infrared heating wire can instantly reach a temperature of 550-650 degrees Celsius when heating the welding surface of the product.
2. The heating distance of the welding surface is 3-6mm, which can be adjusted according to the actual product material and welding effect.
3. Infrared heating wire: Due to the process of insulation (300 degrees Celsius) to rapid heating (600 degrees Celsius) during the pre heating cycle, the temperature uniformity and service life requirements of the heating wire are very high.
Heating voltage: 0-25V, insulation: 300 degrees Celsius
Welding temperature: 700 degrees Celsius Heating time (300-700 degrees Celsius): 1 second
4. Infrared fixed mold: The main function of the infrared fixed thermal mold is to locate the infrared heating wire and block the thermal conduction of the infrared wire.
