Eliminate Degradation in PVC Flat Die
What was the problem?
Material degradation in a PVC sheet die!
The customer observed degradation and corrosion near the end of the manifold section of their PVC sheet die, requiring frequent cleaning and repair. Materials would collect in that region and degrade over time. When PVC degrades, it releases corrosive by-products, which break through the chrome layer and corrode the base metal. The following image shows a photo of a die that has experienced this problem and was sent back to the manufacturer for repair.
