Slot-die Heads
From precision coating in laboratory settings to seamless industrial-scale production, our heads deliver unmatched performance
Standard and Customized Slot-die Heads
Our standard slot-die heads are meticulously crafted to meet industry demands, offering superior performance and reliability. However, we understand that your specific requirements may vary. That's why we also offer customizable options tailored to your unique needs.
Our standard and most sold slot-die head:
Stainless Steel (M315 Heavy): Budget friendly and will solve the task in 95% of all cases.
We also offer slot-die heads in three other materials:
PEEK (Ultra-Lightweight): Ideal for applications where weight is a critical factor.
Stainless Steels (316L Heavy): Known for their durability and resilience.
Titanium (Lightweight): Combining strength with lightweight properties for optimal performance.
In addition to these standard materials, we also provide various alloys such as aluminum-magnesium. Furthermore, we have the capability to manufacture heads in specialty materials like inconel and teflon upon request.

Fitting Kits and Shim Kits
All of our slot-die heads necessitate fitting kits and shim kits for optimal operation. Our range of small laboratory-scale heads is available in various materials and standard widths, including 40 mm, 65 mm, 115 mm, 165 mm, 195 mm, and 305 mm. These dimensions accommodate working widths ranging from a single 10 mm or 13 mm stripe to 50 mm, 100 mm, 150 mm, 180 mm, and 280 mm, respectively. We keep standard heads and shims in stock and offer custom shim fabrication for our clients. Plus, we can tailor slot-die heads and kits to your specific needs.
Fitting Kits
Our fitting kits come preassembled with hoses and fittings, simplifying the connection of your slot-die head to a syringe for ink feeding. Crafted from high-quality materials, the fitting kit ensures durability and can be reused multiple times
Shim Kits
By adjusting the thickness of the shim, you can finely tune the gap between the slot-die lips, influencing the amount of material deposited onto the substrate during the coating process. Shims play a crucial role in achieving precise and uniform coatings.
How to Select the Correct Slot-die Head
Selecting the right slot-die head involves considering various options and decisions. To guide you through this process, we’ve compiled a list of questions. Please review them and answer them as well as you can to ensure that you choose the most suitable product for your needs.
Are you coating at high speed (>2 m min¹) or low speed (< 2 m min⁻¹)?
Is your ink material high viscosity (>100 mPas) or low viscosity (0.6-100 mPas)?
Does your ink exhibit Newtonian, thixotropic or rheopexic behavior?
Do you need to pump ink at high pressure?
Is your ink homogenous or inhomogenous (i.e. it contains particles)?
If it contains particles, are they magnetic?
Is the chemistry of your ink mild (i.e. organic solvents) or extreme
(i.e. strongly corrosive or redox active)?
Is your ink very costly or is it available in volume?
Do you need to coat lines or do you need to apply an even coat over
the entire working width?
What coated width do you need (working width)?
Do you have geometrical constraints surrounding your coating platform
(i.e. inverted coating or narrow space)?
Do you need to heat or cool your ink during coating?
Do you need constant agitation of your ink to maintain homogeneity?
Do you have a requirement for very high precision?
Is the budget for you application limited?
Do you need a general-purpose multiple use slot-die head or will it be
dedicated to one process and only one ink?
By answering these questions, you’ll discover that decisions regarding materials, dead volume, feed ports, connections, lip design, precision, special functions, and more have already been addressed. Generally, our budget-friendly option will meet your requirements, but occasionally, there may be situations where low-cost solutions are not available.
