Custom Shims and Plates for Slot-Die Coating
Design your own shims an plates. Laser-cut shims and plates made of stainless steel – manufactured according to your design, for slot-dies of any manufacturer and for self-developed slot-dies. Send us your DXF file or a dimensioned drawing, choose thickness and quantity, and receive your custom shims typically within two weeks.
Why custom shims?
In a slot-die, the shim defines the slot gap and the coating width; plates can define the protrusion. Standard shims do not always fit your process. Custom shims are the solution when
- the shim thickness (slot gap) shall be changed
- the coating width shall be adapted,
- the protrusion shall be adapted
- shims for your slot-die are no longer available, or you use a self-developed slot-die
Key facts
- Laser cut stainless steel
- Thickness: 75 / 100 / 150 / 200 µm
- Precision of the manufacturing process: ± 10 µm
- Outer size: min. 20 × 20 mm, max. 200 × 200 mm
- Smallest radius (inner and outer corners): 0.1 mm
- Your input: DXF file (scale 1:1, mm) or dimensioned drawing – hand drawings are accepted
- Delivery time: typically 2 weeks after all technical questions are clarified
How it works
- Send your request with the form below: your DXF file(s) or drawing(s), thickness and quantity for each design, and your desired delivery time.
- Design check: we check your files for manufacturability. If problems are to be expected, we make small adjustments in agreement with you – or you send us a revised file. If you only have a dimensioned drawing, we create the digital drawing for you.
- We send you a quotation.
- Manufacturing and shipping: after your order, the shims are manufactured and shipped – typically within 2 weeks after all technical questions are clarified.
You can combine several designs and thicknesses in one request, e.g. Design 1: 5 × 100 µm; Design 2: 2 × 150 µm.
Design recommendations
We recommend the following design rules. They make your shims manufacturable and easy to handle:
- Avoid loose tabs and no parts that fall out after laser cutting.
- Round all corners with R ≥ 0.1 mm. Sharp corners cause problems in manufacturing, and lint tends to collect in them during cleaning.
- Dowel pin 1: round hole with oversize – pin Ø + 0.1 mm (+50 µm on the radius).
- Dowel pin 2: slotted hole along the axis between both pins, same width as the round hole, straight section ≥ 0.3 mm. The pin is expected in the middle of the straight section.
- Screw holes: clearance hole approx. 0.5–1 mm larger than the screw, e.g. M6 → Ø 6.5 mm, if the shim is positioned by dowel pins.
- Outer size between 20 × 20 mm and 200 × 200 mm.
All details, figures and a checklist are given in our data sheet. A DXF template with an example shim helps you get started (see downloads below).
Prices
Prices on request. Unit prices depend on quantity, size, thickness and complexity of the geometry; quantity discounts apply to the total number of shims in an order. Design check, digital drawing (if required) and shipping are listed in the quotation.
