The study of product design, design and function of the owner wanted My inbox (1 new) China mold Forum - Mechanical Technology Center - industrial design - browse: hot plastic welding Seminar You are the 236th reader of this post. Post topic: * post topic: thermoplastic welding lecture cbtamoi Level: technician article: 148 points: 177 Charm: 1 cash: 451 sects: plastic mold registration: 2003-412 flowers, eggs (0) Thermoplastic plastic welding seminar thermoplastic thermoplastic welding is usually considered irreversible. A few processes such as induction welding can produce reversible assembly. As for the choice of what kind of method should be used in the design to make early parts, because of the welding requirement for product design may be important, and different welding methods with noticeable difference. 1. 2. 3. 4. 5. 6. ultrasonic welding 7. vibration welding rotary welding hot plate welding welding welding welding heat contact (resistance) (0) 8. hot extrusion welding welding technology is commonly used in plastic pipe welding, sheet or semi-finished products instead of injection molding parts. But many thermoplastic molding parts, especially thermoplastic automobile plate is used heat welding technology to repair, also sometimes used for the preparation of hot gas welding plastic mouldings. Ultrasonic welding method is the most common the thermoplastic parts is ultrasonic welding. This method is the use of low amplitude, high frequency vibration energy (ultrasound) and molecular surface friction welding pad plastic parts connected the required heat (sinusoidal ultrasonic vibration). Ultrasonic welding occurred in the frequency range of 20-50kHz, the amplitude range of 15-60um. in low 15kHz (high amplitude) audio is s
