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).

Technical Specifications

Typical Applications
Wig industry (lace mesh skin-color coating, ultra-thin invisible coating) · Coatings & inks (water-based paints, printing inks, conductive inks) · Adhesives (pressure-sensitive, water-based, laminating adhesives) · Papermaking (specialty paper, surface sizing, functional coated paper) · Advanced electronic materials (PET films, optical films, Li-ion battery substrates, nano coatings) · Textiles & nonwovens (water-repellent coating, functional finishing) · Medical & cosmetics (gels, medical dressings, facial masks) · Research & education (teaching labs, new material R&D, third-party testing)

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.
