Heated Slot-die Head - 65 mm (50 mm Coating Width)

Precision-Engineered Slot-die Heads for High-Quality Thin-Film Coating

infinityPV's precision-engineered slot-die heads are designed for accurate, uniform, and repeatable thin-film coating across a wide range of materials, substrates, and applications. Available in PEEK, stainless steel (316/316L), and titanium, they combine optimized internal geometry and low dead volumes to support precise material delivery and consistent coating performance. With standard head widths ranging from 40 mm to 305 mm, they are suitable for laboratory research, process development, and pilot-scale coating applications.

Designed for applications including battery electrodes, fuel cells, printed solar cells (OPV, perovskite, DSSC, and tandem), OLEDs, sensors, adhesives, sealants, and other functional thin-film technologies, our slot-die heads offer flexibility across different coating formulations and process requirements.

Material Selection and Coating Performance

Choosing the right slot-die head material is important for chemical compatibility, handling, and coating process requirements. infinityPV offers three material options:

• PEEK: Lightweight construction, convenient handling, and excellent chemical resistance. Particularly suitable for laboratory coating applications.

• Stainless Steel (316/316L): Robust construction and mechanical stability for demanding coating processes.

• Titanium: An alternative for applications requiring specific material and chemical compatibility properties.

All versions feature optimized internal geometry and low dead volumes, helping minimize material retention and waste. This is particularly beneficial when working with expensive functional inks, limited material quantities, or frequent formulation changes.

Practical Two-Part Design and Heated Options

Our slot-die heads feature a streamlined two-part construction that simplifies assembly, disassembly, and cleaning, helping reduce maintenance time and downtime between coating experiments. Lightweight PEEK heads offer convenient positioning on automated coating platforms, particularly for low-pressure and low-viscosity applications. We also offer heated slot-die heads for coating processes requiring temperature control, providing additional flexibility when working with temperature-sensitive materials and formulations.

Standard Products and Custom Solutions

We maintain stock of standard slot-die heads, shim kits, and fitting kits for convenient ordering and availability. Interchangeable and customized shims allow different coating configurations, while our low- and high-viscosity fitting kits provide connection options for different coating formulations and setups. For applications with specific requirements, we also manufacture custom slot-die heads and custom shims.
