Fully Automated Scrape Coating Machine – Customizable System for Roll-to-Roll & Sheet Substrates

Fully Automated Scrape Coating Production Line – Customizable System for Roll-to-Roll & Sheet Substrates

Product Overview

Our Scrape Coating Machine is a versatile and high-performance system designed for applying precise, uniform coatings onto a wide range of substrates.

Substrate Category	Specific Materials
Synthetic Leather	PU leather, PVC leather for automotive, furniture, footwear
Rubber Flooring	Rolled rubber sheets, rubber tiles, gym matting
PVC Flooring	LVT (Luxury Vinyl Tile), WPC, SPC flooring planks
PET Sheets	Transparent PET films and sheets for packaging and graphics
Slate / Stone Veneer	Engineered stone sheets, decorative slate panels
Decorative Laminates	High-pressure laminates, HPL, CPL sheets

The scraping process uses a rigid doctor blade positioned over a backing roller or flatbed to spread coating materials evenly across the substrate surface.

Coating uniformity (±2% thickness tolerance)
High material efficiency (≥95% transfer rate)
Smooth, pinhole-free finish
Wide viscosity tolerance (50 - 8000 cps)

Supported coatings include water-based acrylics, PU dispersions, solvent-based lacquers, UV-curable resins, wear-resistant layers, and anti-slip topcoats. The system is fully customizable to meet specific production requirements, from pilot-scale R&D to high-speed mass production.

Frequently Asked Questions

Q1: Can this machine handle both roll materials (like PET/PVC) and rigid sheets (like slate or flooring planks)?

A: Yes. The system is designed with a dual-feed option - an unwinding unit for rolls and a vacuum conveyor table for sheets. This is a customizable feature based on your production mix.

Q2: What coating materials are compatible?

A: The machine supports water-based acrylics, PU dispersions, solvent-based lacquers, UV-curable resins, and hot-melt adhesives. We can recommend blade materials and drying configurations customized to your coating formulation.

Q3: How accurate is the coating thickness on textured substrates like slate or embossed flooring?

A: The doctor blade system follows the substrate contour, ensuring consistent film thickness even on textured surfaces. The blade gap is customizable and adjustable online via the HMI to accommodate surface irregularities.

Q4: What is the typical line speed for flooring applications?

A: For PVC flooring with UV coatings, line speeds typically range from 5 - 30 m/min. For PET films, speeds can reach 100 - 120 m/min. Speed is customizable through servo drive parameters and drying capacity.
