Overview
OSP-30 L2000φ 16 formed wire coating bar is a professional Spreader tool produced by OSP brand in Japan. It is manufactured by extrusion process, made of 304 stainless steel, and has a chrome-plated surface. This product is specially designed to replace traditional steel wire coating bar. It can precisely control the wet film thickness to 1.5μm and realize ultra-thin Spreader. It is widely used in liquid Spreader adjustment in film, Glass, paper and other industries.
Features
1. Made by extrusion process, the bottom of the groove is wider than the traditional steel wire coating bar, and the Coating Weight is larger
2. Accurate control of wet film thickness to 1.5μm for ultra-thin Spreader
3. Effectively solve the problem of loose wire and broken wire of traditional steel wire coating bar
4. Easy to clean, not easy to clog
5. The surface shape can be freely changed
6. Specifications and lengths can be customized to meet different production needs
Principle
Spreader liquid on the surface of the substrate, using D-Bar formed wire coating bar to adjust and scrape off the excess liquid amount. Through its specially designed groove structure, the thickness of the Spreader can be precisely controlled to achieve a uniform liquid Spreader effect.
Applications
Film, Glass, Paper, Encasement Material, Tape, Magnetic Card
Steps
1. Spreader liquid on substrate surface
2. Use D-Bar formed wire coating bar to adjust the amount of liquid
3. Spreader thickness control by scraping off excess liquid
