Compact Double Roller Coater with Manual Gap Adjustment and Quick Roller Change for Precision Coating

This compact, space‑saving system includes:

• Manual or Motorized Infeed Table – for small panels and sheets
• Compact Double Roller Coating Head – integrated into a single module
• Manual Gap Adjustment with Digital Readout – ±0.01 mm accuracy
• Hand Crank or Servo Roller Gap (options available)
• Small‑Capacity Coating Circulation – 5‑10 liter tank, manual pump or syringe
• Integrated Drip Tray & Solvent Wash Basin
• PLC or Manual Control (basic or advanced option)
• Curing Unit – optional UV LED lamp (benchtop) or small IR oven
• Outfeed Table – with drying rack

All contact parts are stainless steel, and the machine can be placed on a lab bench or mobile stand.

This Compact Double Roller Coater is designed for small‑batch production, R&D laboratories, prototyping, and pilot lines where flexibility and ease of use are paramount. Unlike large industrial coaters, this machine occupies minimal floor space (approx. 1.5 m × 0.8 m) yet delivers the same double‑roller precision coating technology. It is ideal for coating small metal sheets, wood samples, composite coupons, and decorative panels up to 600 mm wide.

The machine features a manual gap adjustment system with a digital micrometer readout, allowing operators to quickly set the metering and application gaps from 0 to 5 mm with 0.01 mm resolution. The application roller is available in multiple hardness options, and the entire roller set can be swapped out in minutes for different coating materials. The coating supply system is simple – a manual pump or syringe dispenses coating onto the rollers, and excess is collected in a removable tray.

Despite its compact size, this machine can achieve coating thicknesses from 5 µm to 300 µm, with accuracy comparable to industrial models (±2 µm). It is perfect for developing new coating formulations, testing different substrates, or producing small commercial batches of custom‑coated panels.

• R&D and laboratory – developing new coatings for metal, wood, plastic
• Prototyping – producing small quantities of coated samples for customer approval
• Small‑batch production – custom furniture pieces, architectural samples, art panels
• Educational institutions – teaching coating technology
• Repair and touch‑up lines – recoating small areas or batches
• Test panel production – for quality control and adhesion testing

The compact coater is highly customizable for diverse R&D needs:

• Customizable working width – from 100 mm (lab scale) to 600 mm (pilot scale)
• Customizable roller material and hardness – quick‑change roller sets available
• Customizable gap adjustment – manual (standard) or servo‑controlled (precision R&D)
• Customizable coating supply – syringe pump, peristaltic pump, or gravity feed
• Customizable conveyor type – belt, roller, or manual slide
• Optional benchtop UV LED curing module – 365/395 nm, adjustable power
• Optional data logging – USB export of coating parameters
• Customizable voltage – 110V for North America, 220V for others
• Customizable color and branding – for OEM or lab integration

• Compact footprint – fits on a lab bench or small production area
