New Technolody Added to M&P Services: Laser Welding of Plastics!
Laser Welding Concept
The laser beam penetrates the upper "transparent" component and is converted into heat by the absorbing lower component. Since both components need to be pressed together (as in other methods), heat is conducted from the absorbing lower component allowing both parts to melt and create a bond only where the laser beam is directed. Clamping of the plastic components that are to be assembled is still essential so that intimate contact is made to allow the laser beam to melt exactly where the parts need to be bonded together.
Advantages of laser welding

• No particulate is generated
• Vibration-free process
• Hermetic seals are achievable
• No wear on the tooling
• Optically perfect weld joint area
• High-precision
• Simple joint geometry
