Lab Precision Vacuum Slot Die Coating Machine w/Heating Vacuum Chuck and Syringe Pump Used in Glove Box

Power

· 110V - 240V AC 50/60Hz for worldwide use

· 280W 

· UL /CSA certified power supply (110~ 240VAC - 24VDC) is separated from the coating unit

· The coating unit has 24VDC input and is driven by a 24VDC motor, which can be used under the Ar atmosphere glovebox to avoid arcing and short circuit.

Slot Die Head

· 100 mm width slot die head with 6 pecs shims with thickness 0.08, 0.1, 0.2, 0.3, 0.4, and 0.5 mm included

o different width <100mm) shim may be available upon request at the extra cost

· Different-width shims are available upon request. ( 12- 50 mm width

· Minimum coating thickness: 5 microns (depending on slurry viscosity)

· Tube connection: M6 connector with 3mm OD tube from the middle of the head.

· Slot Die Heads are included with the "Slot Die Coating" and "Combination" Options.

Syringe Pump

· Built-in syringe pump with a variable speed in the range from 0.05 to 5.0 mm/s

· Touch screen panel for setting up the parameters

· One 20mL stainless steel syringe with a plastic plunger is included. 

· A O.D. 3.2 mm PTFE tubing and its connection accessories are included. 

· The syringe is included with the "Slot Die Coating" and "Combination" Options.

· We have changed the syringe fixture part since May, 2024, so regular plastic syringes are included instead of stainless steel ones.  

Gap Control

· Two micrometer heads are built in the travel rod of the coater to adjust the gap between the slot die and the substrate

· Two digital drop indicators are provided to move with the slot die.

· The Micrometers are included in the "Slot Die Coating" and "Combination" Options.

· The flatness resolution of the vacuum chunk plate is around 5-10 um.

Travel Speed & Length

· Travel Speed: 0.05 - 30 mm/s adjustable via touch screen control panel

· Maximum coating area: 100 mm W x 100 mm L

Heated Vacuum Chuck

· Vacuum chuck made of aluminum alloy with small holes

· The small vacuum pump is built inside the coater and driven by a 24VDC motor

· Vacuum chuck Area: 150mm (W) x 130mm (L)

o Surface roughness ≤ 5 μm

o Surface flatness ≤ 15 μm

o Linear Motion Levelness ≤ 20 μm

· Heating elements are installed inside the chuck which can reach 120 ºC 

· Precision digital temperature controller with ± 1ºC accuracy

Control Panel

· 4" color touchscreen panel to set coating speed, heating temperature, and syringe pump speed

Application Note

· Coating thickness is not dependent on or equal to the gap between the slot die head and substrate. 

· Usually, the gap shall be larger than the coating thickness. Coated thickness is strongly dependent on slurry viscosity, coating speed, and flow speed. ( Lower viscosity, low flow rate, and low speed will result in a thinner film. Please practice finding the best parameters which suitable for you

· Example 5% carbon+ polymer, viscosity: 500mPa·s, substrate: Al foil of 16 um,

o Gap: 200 um, Slurry feeding rate:: 0.1 ml/minute , Coating speed: 12mm/s

o Dry-coated film thickness: 5 um +/- 1 um
