Infrared Welding

Infrared (IR) welding is a non-contact thermal welding technique that produces very strong air-tight & liquid-tight welds. Infrared radiation is most commonly known as the heat from sunlight and as with any form of light, the radiation is electromagnetic which is transmitted at very high power levels. Infrared radiation can be used as a deliberate heating source which is making it more popular in industrial & semiconductor manufacturing processes. When these wavelengths can be controlled (IR Welding) thermoplastic parts can be heated to molten temperatures very quickly and then joined together similar to hot plate welding (socket fusion, purebond).

Advantages of IR Welding

• Greater design flexibility in material choice (no contact applications)
• No replacement inserts/coating material for the platen (heater) to prevent adhesion with the parts (no contact apps)
• Up to 50% faster than conventional butt fusion
• Low risk of contamination (no contact applications)
• Minimal bead
• Low stress weld
• Entirely reproducible for consistent orders
