This slot die coater for sheet substrates is developed for high-temperature coating research, capable of fabricating ceramic, crystal, battery and special nano films. It consists of four core systems: extrusion die head, coating platform, feeding unit and control system.

Key Features

Large-area uniform heating guarantees precise substrate temperature control.
Flat coating with motor-driven die for stable, adjustable coating speed.
Adjustable coating speed; aluminum vacuum chuck enables fast substrate loading.
Connected to an external vacuum source to hold substrates without deformation.
High-performance stainless steel die head with strong corrosion resistance and wide compatibility.
Shim sets of various thicknesses optional for fluids of different viscosities.
Integrated automatic feeding system with interlinked functions.
High-precision syringe pump supports low-flow feeding to meet low-rate dispensing demands.
PLC & large touchscreen control for convenient parameter configuration.
