DATAMAKER High-Precision Slot-Die Coater Specification Sheet
Brand: DATAMAKER Model: DT-2030
I. Process & Application
The coating system consists of a feeding unit and coating unit. The coating unit comprises precision-machined upper/lower dies and thin shims installed between them. The feeding unit includes material storage, syringe pumps for delivery, and filtration devices.
By controlling the relative motion between the coating die and substrate (glass, stainless steel, plastic, etc.), the system extrudes liquid chemical materials through the die gap to form thin films. Film thickness is determined by flow rate and substrate speed, offering:
High uniformity
Wide viscosity range (1–2,000 cps)
High-speed coating
Large-area film capability
Applications:
Organic (OPV) & perovskite (PVK) solar cells
Discontinuous substrates (e.g., LCD glass photoresist)
Optical films (brightening, hardcoat, polarizing, diffusion)
OLED coatings
Customizable Options:
Heated stages
Gas purging systems
Multi-size coating heads & shims
II. Design Scheme
Machine Design
Leveling System:
Dual-stage adjustment for large-area platform flatness.
Base: High-precision granite platform (low thermal expansion).
Heated stages use stainless steel; non-heated stages use granite with micro-adjustment.
Coating Head:
SUS630 martensitic precipitation-hardening stainless steel (patented design).
Organic solvent-resistant, anti-deformation.
Gap adjusted via stainless steel shims (0.05/0.08/0.1 mm options).
Motion Control:
Servo motors + encoder + linear scale (dual closed-loop).
Linear servo motors for platform stability.
Integrated Features:
Syringe pump with auto-filling, degassing, and cleaning (requires disassembly).
Multi-zone vacuum adsorption for substrate fixation.
Multi-segment coating for edge thickness control.
Air knife system (adjustable height/angle).
Waste Management:
Built-in recovery for spent fluids.
Software Functions
Real-time monitoring: Displays platform position, head height, gap thickness, coating/injection speed, and volume.
Recipe storage: Saves 8+ parameter sets for repeatability.
Safety protection: Auto-stops in hazardous zones via sensor feedback.
