IR Preheating Vibration Welding Machine
Cleaner Plastic Welding with Infrared Preheating and Precision Vibration Welding
Jfortune IR preheating vibration welding machines combine controlled infrared heating with vibration welding to reduce particles, improve weld appearance and achieve strong, repeatable joints for automotive lighting and other thermoplastic components.
What Is IR Preheating Vibration Welding?
Vibration welding, as it is known, is a linear friction welding method. Infrared preheat vibration welding, which involves adding infrared preheat at the beginning of the cycle to soften the welding ribs and reduce particulate matter generated during the vibration process, is a relatively new and “cleaner” method of welding plastics.
Compared to infrared welding, infrared preheating vibration friction avoids the problems of material degradation due to prolonged infrared heating and the risk of thermal damage to other components. Compared to traditional vibration welding, there is no particulate contamination, and a better appearance.This process is particularly suitable for automotive lighting and plastic components where cleanliness, weld strength and appearance are important.
Jfortune infrared pre-heating vibration welding machine has been widely used in automotive lighting recently.
Jfortune has many different standard IR cleaning vibration welding machines. These machines are from small to large machines, and per different welding areas. Jfortune also has a high capability of automation welding solutions, we can customize different automation equipment along with the vibration welding machines to meet customers’ different requirements.
- The addition of infrared preheating raises the temperature of the welding rib area, softening the material and thus avoiding particles caused by dry friction, while also reducing the amplitude required for vibration and reducing residual stresses in the weld of the part, ultimately achieving the desired weld performance and assembly appearance.
IR Preheating Vibration Welding vs. Conventional Vibration Welding
| Conventional Vibration Welding | IR Preheating Vibration Welding | |
|---|---|---|
| Initial Contact | Cold / dry friction | Preheated weld ribs |
| Particle Generation | Higher | Reduced |
| Weld Appearance | Standard | Cleaner |
| Vibration Requirement | Higher | Can be reduced |
| Visible Weld Area | Moderate | Better suited |
| Automotive Lighting | Applicable | Particularly suitable |
| Process Complexity | Lower | Higher process control |
- The figure below is a schematic of particle generation. The left diagram shows the upper and lower parts in the cold state with dry friction, generating a lot of particulate matter. The right diagram shows the upper and lower parts under the condition of softening in the hot state, and no particulate matter is generated.
Process Flow
01 IR Preheating
Welding ribs are heated without direct contact.
→
02 Part Transfer
The IR heating unit retracts and the parts move into welding position.
→
03 Vibration Welding
Controlled vibration and pressure complete the plastic joint.
→
04 Holding & Cooling
The welded components are held under pressure for dimensional stability.
