Value Delivery:
These on demand heated food trays were originally designed for ultrasonic welding but failed to meet critical specifications for leakproof performance, strength, and NSF dishwasher compliance. The PA6 material posed additional challenges due to its welding difficulty, and the ultrasonic horn left unwanted markings on the parts. To overcome these issues, Emabond implemented a Tongue and Groove joint design on the exterior of the plate, ensuring a secure and seamless bond. This solution resulted in NSF approval, a low scrap rate, and a distortion-free weld, delivering both reliability and production efficiency.
