Cost performance options expand for EDI cast film dies

Nordson Corporation has adapted an extrusion die technology that has been in global use for 15 years and now offers it under the new name Uniflow as an alternative for cast film applications that do not call for the unique capabilities of the widely used EDI Contour die.

The Contour die is the most technologically advanced cast film die on the market, with a distinctive “sculpted” shape that is the key to enhanced product quality, raw material conservation, and maximum uptime, noted Scott Smith, business unit director for polymer dies.

The Uniflow die, now available under the well-known EDI brand, was first developed by the Belgian firm Verbruggen, which Nordson acquired in 2011. “While the Uniflow die represents a lower-cost alternative to the Contour die, it provides real advantages in important application areas,” said Mr. Smith. “It is a versatile die whose effectiveness has been proven in both monolayer and multilayer production.”
