Slot-die coating machines and heads

Sheet-based and roll-to-roll coaters for materials research, and the slot-die heads that fit them.

Choose your coating format

Which format fits depends on your substrate, the amount of material you have and how you plan to run your process.

Square icon

Sheet-based

Coat on rigid or flexible sheets, one sample at a time. Suited to formulation screening and small-area devices, with minimal material use.

Shell icon

Roll-to-roll

Coat continuously on flexible substrates, from a compact roll-based coater to modular pilot lines. Suited to longer runs, multilayer builds and process scaling.

Slot-die head icon

Slot-die heads

Interchangeable heads in stainless steel and PEEK, for coating widths from 1 mm to 500 mm. The head sets the coating width, and the machine sets the range.

Roll-based coating machine

The FOM nanoRC is a compact roll-based coater. The substrate is mounted on a rotating roll, so continuous coating conditions can be reproduced on small samples with minimal material use. Open the machine page for specifications and slot-die head compatibility.

Custom slot-die coating solutions

Some processes need a format, a combination of steps or an integration that the standard machines do not cover. FOM adapts existing designs or builds new systems around your process, such as the FOM pontemR2R coating station for existing lines.

Slot-die heads for your FOM coater

Slot-die heads are available to owners of FOM coating machines. Additional heads let you change coating width or material without changing the system.

Platform & tooling

  • The machine provides motion, stability and process control.
  • The slot-die head is the interchangeable part that defines how material is applied.
  • Changing the head changes the coating width or material, without replacing the system.

Compatibility logic

  • Each FOM machine supports a defined range of slot-die heads.
  • Compatibility depends on the machine type and its maximum coating width.
  • The machine sets the limits, and the head is selected within that range.

Key variables

  • Width sets the coating area, from 1 mm to 500 mm.
  • Material sets chemical compatibility: stainless steel, or PEEK for chemistries that attack stainless steel.
  • Shims and meniscus guides set the stripe pattern and stabilize the bead.

FOM’s Tensor coating software

Turns coating expertise into repeatable, scalable recipes. A clean, guided user interface takes you from setup to run with recipe-based control and storage to reuse coating protocols and test coating parameters in a structured way. The same intuitive workflow spans research tools and pilot lines, helping you scale by width and throughput without reworking your process. Advanced options—such as sequences, drying/profile management, web handling, and tension control.

Why it matters

  • Save time with easy setup and reusable recipes.
  • Get the same results every time with locked settings and history tracking.
  • Scale with ease by using familiar software and protocols as you move from the lab to the pilot line

Frequently asked questions

What is the difference between sheet-based and roll-to-roll slot-die coating?

A sheet-based coater coats one substrate at a time, held flat on a substrate holder. A roll-to-roll coater coats continuously on a flexible web that runs from unwind to rewind through the coating and drying sections. Neither is a step up from the other. The right choice depends on your substrate, the amount of material you have and how you plan to run your process.

Which FOM coater fits my research?

Start with your substrate, the coating width you need and your drying requirements. The sheet-based FOM scalarSC and vectorSC coat up to 200 mm wide and the alphaSC up to 500 mm. On the roll side, the FOM photonR2R coats up to 50 mm, the nanoRC up to 100 mm, the omicronR2R up to 200 mm, the omegaR2R and compact moduloR2R up to 300 mm, and the moduloR2R up to 500 mm. Our Science & Learning team can help you match a machine to your process.

Can I test my ink or slurry before choosing a machine?

Yes. Our Science & Learning team runs technology demonstrations and commissioned research with your own ink or slurry and substrates, online, at your site, at a FOM facility or at one of our partner labs.

Can FOM build a customized coating machine?

Yes. Custom dimensions, multiple coating stations and in-line processing or characterization can be added to a standard platform. Each FOM moduloR2R is configured to the customer's requirements on a standardized base.

Where do I find specifications and datasheets?

Each machine page has a specifications table and a datasheet download. The product brochure covers the full portfolio in one document.
