    Flatbed Coating Tester

    The AT-TB-1100 series flatbed coating tester is a precision laboratory coating device developed by Shandong Annimet, designed for applying coatings, adhesives, hot melts, and conductive/nano materials onto substrates such as paper, nonwovens, glass, and metal foils. The coating speed is adjustable from 1-2000 mm/min, with an effective area of 300×400 mm. It supports multiple coating methods including doctor blade and wire bar, and offers options for a vacuum adsorption table and heated base plate (RT-200°C). Touchscreen control makes it an ideal replacement for manual drawdown.

Product Introduction
The AT-TB-1100 series flatbed coating tester is a precision laboratory instrument built for material R&D and process validation. With a core design philosophy of "reliable, flexible, and easy to operate," it is widely used in new energy, electronic materials, biomedical, packaging, and printing fields. It provides efficient solutions for small-batch lab trials, formulation optimization, and quality inspection. The machine features touchscreen intelligent control with storable parameters, precision guide-rail lead-screw transmission for smooth, quiet operation.


Key Features
High-Precision Uniform Coating: Precision guide-rail and lead-screw drive with adjustable speed of 1-2000 mm/min, delivering uniform, repeatable coatings that replace manual drawdown with traceable data.
Multi-Coating Mode Compatibility: Supports wire bar, four-sided doctor blade, adjustable blade, and slot die coating methods (optional), covering ultra-thin to conventional thick film applications for wig mesh, paints, inks, adhesives, etc.
Optional Vacuum Table: Secures thin and flexible substrates, preventing wrinkling, stretching, or skewing during coating.
Optional Heated Base Plate: RT-200°C precision temperature control, enabling integrated coating, preheating, and low-temperature curing processes.
Touchscreen Intelligent Control: Touchscreen operation with storable recipes for one-touch recall; simple to use, easy to change materials and clean.
Robust Corrosion-Resistant Body: All 304 stainless steel housing; die steel platform quenched, mirror-polished, and chemically plated for ±2.5 μm flatness (within 300 mm).

FAQ
1. Uneven thickness or streaks
Debris or deformation on doctor blade, air bubbles/high viscosity in coating, or unclean table. Clean/replace blade; stir, defoam, and filter coating; clean table and flatten substrate.
2. Irregular edges, overflow
Blade not level, substrate not firmly fixed, or excessive coating amount. Level the blade; fix substrate with clamp/vacuum; control appropriate coating volume.
3. Jerky motion, shaking, abnormal noise
Dust/lack of oil on guide rails and lead screw, loose drive screws, or too sudden start/stop. Clean and lubricate rails; tighten fasteners; smooth acceleration.
4. Pinholes, craters, pits in film
Air bubbles/impurities in coating, oil/dust on substrate, or high humidity. Filter and degas coating; pre-clean substrate; keep lab dry and dust-free.
5. Heated model slow to heat, inaccurate temperature
Scale/build-up on heating plate, temperature controller uncalibrated, or air draft from vents. Clean plate after cooling; recalibrate controller; move away from air vents.
6. Poor repeatability, inconsistent thickness between runs
Inconsistent blade gap, speed, or coating amount each time; platform precision drift. Fix process parameters and store recipe; standardize procedure; periodically verify platform and blade accuracy.
7. Weak vacuum, substrate not held
Clogged vacuum holes, line leaks, or insufficient pump vacuum. Clear adsorption holes; check line seals; adjust pump pressure.

Flatbed Coating Tester



The flatbed coater is one of the most versatile laboratory coating preparation devices. Its basic principle involves applying a coating onto one end of a substrate that is fixed on a flat platen. A doctor blade or wire-wound rod is then moved at a constant speed and pressure across the substrate, spreading the coating into a uniform wet film. The resulting film thickness is determined by the gap between the blade and the substrate, the coating viscosity, and the coating speed. Modern flatbed coaters have evolved from manual spreading to motor-driven automated systems, enabling precise control of speed, pressure, and heating temperature, while also incorporating vacuum suction to hold thin or soft substrates in place. This equipment is an essential tool for formulation development and quality control in fields such as paints and coatings, inks, adhesives, and new energy materials.
