Multi-talented slot die increases productivity

摘要

This multi-manifold die for proximity coating of fluids onto web substrates enables processors to use a single die to apply two or more coatings simultaneously.This helps achieve higher productivity than with multi-stage processes and avoids oxidation and contamination that coatings undergo between stages.The manufacturer says that one processor who is employing the die to process high-performance electronic films has already successfully used both dual-and triple-manifold versions of the Ultracoat slot die coating head to apply various layers of ceramic slurry to polyester film substrates.
