Achieving Higher Burst Pressures and Reliability with Emabond Welding Technology for Food Service Water Filters
The Plastic Welding Challenge
Emabond is the go-to solution for major food service water filter OEMs needing a plastic welding solution capable of withstanding extreme performance demands to protect the integrity of drinking water and their brand’s reputation. Traditional spin welding presented significant challenges. Excess flash created risks of contamination, and the process often struggled to consistently achieve the required burst pressure and hermetic sealing performance. Production teams battled with high scrap rates, slowing efficiency and raising costs.
The Food Service Water Filters Required:
- High burst pressure exceeding 500 psi.
- Numerous model variations across sizes and designs
- Weld line diameters from 2” to 4”
- Clean, flash-free joints with no particulate contamination.
- NSF 61 Compliance for potable water applications.
