Coating Dies

Coating production for hot-melt adhesive,pressure-sensitive glue,water-soluble solution,other solvent and solution.

Overview

High-precision narrow gap coating die,adopting world-advanced R&D technology to test polymers' characteristics to get the optimized flow channel design.Early at preliminary designing stage,our dedicated engineer team predicted all kinds of problems that may occur during the production as many as possible and meanwhile they provided related solutions.

Coating die series

Mainly including: narrow gap coating die,coating and scraping coating die,near-contact coating die,monolayer or multilayer coextrusion coating die.

Traditional coating die type:

Product Specification
