Bunting introduces new flexible die coating

October 5, 2010

The coating repels adhesives and keeps unwanted material from getting stuck in the die cavities.

Bunting Magnetics Co. has developed a new coating for its flexible die product line called Repel. The coating provides a clear, non-stick finish that repels the most aggressive adhesives, according to the company.

“The Repel coating keeps the die very flexible and prevents adhesive or label material from embedding in the cavities of a die,” says Mike Wilks, Bunting’s general manager for the flexible die division. “It won’t flake off like other coatings do, giving our customers less downtime and better die cuts.”

Wilks says that Repel offers a strong silicone-based layer of protection for many different applications. “Many tag and label manufacturers will use different types of foam in the production line to keep material from sticking in the cavity of the flexible dies they are using,” he says. “The Repel coating reduces the need to use foam in some applications and helps manufacturers create a cleaner production environment and reduce their total cost. This coating is also suitable for cold foil applications. It reduces the likelihood that thin foil material will stick in the base of a die. The silicone base of the coating enhances foil release, from the tight fit typical of these applications.”

Bunting also offers Diamond and Black Diamond coatings, which increase the hardness of flexible dies. “These coatings allow our flexible dies to run four times longer than ordinary dies,” notes Wilks. “The Diamond and Black Diamond coating process makes our dies highly resistant to cracking and chipping which helps quadruple the life of the die.”
