Types of Plastic Welding
Infrared Plastic Welding
Infrared plastic welding is a relatively new technique ideal for large part assemblies with high hermetic and strength requirements. This process uses a controlled infrared light emitter to melt the joining surfaces, making it especially useful for blow-molded assemblies.
Benefits
- No tooling or part contamination
- Reduces the amount of flash
- Rapid changeover
Ultrasonic Plastic Welding
Ultrasonic plastic welding creates frictional heat in a focused area by converting high-frequency energy into a mechanical motion (vibrations). This method is used to weld plastic to plastic, plastic to metal, and plastic to vinyl, forming a molecular fusion.
Benefits
- Versatile and flexible with little fixture modifications or tooling changeover
- Rapid weld confined to the joint of bonding areas
- Consistent and repeatable
- Replaceable fasteners and adhesives
Hot Plate Plastic Welding
Hot plate plastic welding is ideal for large part assemblies. It involves applying heat to the parts’ joint areas for a predetermined duration, then withdrawing from the heat source and bonding the parts as they solidify under pressure.
Benefits
- Strong sealing method
- Compatible with nearly all thermoplastics
- Able to weld complex shapes and large parts
