Membrane Press Pin Replacement
We renew worn membrane press pins to original dimensions, and can upgrade you to a magnetic pin system.
When Should a Pin Be Replaced? (Wear Signs)
Membrane press pins wear over time, reducing press quality and pin positioning accuracy. The signs below indicate a pin replacement is needed. We manufacture pins compatible with Bürkle (Multi-Pin / Multifoiler BTF) and Wemhöner (Variopin / Variopress) presses to original dimensions and tolerances.
Dimensions, Tolerance and Material
4 part families we produce on the Goodway SW-20 CNC Swiss-type lathe — 40 standard types in total, across ⌀4–20 mm.
| Part family | Diameter | Length | Tolerance | Material | Types |
|---|---|---|---|---|---|
| Press PinHardened flat-ended press pin for membrane press ejection stroke.Code & size table → | ⌀4–18 mm | 21–81 mm | h6 | Steel | 10 |
| Guide PinGuide pin with conical lead-in tip and flat shoulder for plate alignment.Code & size table → | ⌀6–20 mm | 23–75 mm | h7 | Steel | 10 |
| Pin Plate PinStepped cylindrical locating pin with seating shoulder for plate mounting.Code & size table → | ⌀6–20 mm | 16–58 mm | m6 | Steel | 10 |
| Guide BushingStraight-bored guide bushing directing precise axial travel of the press piston.Code & size table → | ⌀5–20 mm | 12–31 mm | h6 | Stainless Steel | 10 |
Tolerance classes: h6, h7, m6. Materials: Steel, Stainless Steel. These ranges show our production scope; the final dimensions and tolerance of your part are set from a technical drawing or a sample, according to the brand and model of your press. Price and lead time are given with the quotation.
- Marks, shadows or a distorted pattern in the press
- Position drift / non-repeatable placement
- Loose hold, pin play in the seat
- Visible wear, burrs or deformation
How Is a Pin Replaced? (Step by Step)
- 1Wear diagnosis: check press defects and the pin seat.
- 2Removal: extract pins with a pin puller without damaging the plate.
- 3Seat cleaning: remove chips/burrs and inspect the seat.
- 4Fitting: install a new pin (or a magnetic pin body) to original dimensions.
- 5Tolerance check: verify position and flatness, run a test press.

Upgrade from Classic Pin to Magnetic Pin
During replacement you can convert your classic pin plate to a magnetic pin system (retrofit): pattern changes in seconds and wear-free operation. Let's determine the right solution for your press brand and model.
Frequently Asked Questions
How is a membrane press pin replaced?
Wear diagnosis → removal with a pin puller → seat cleaning → fitting a new pin to original dimensions → tolerance check, without damaging the plate.
When should a pin be replaced and how long does it last?
Replace when you see marks, position drift, loose hold or visible wear; lifespan depends on press intensity and material.
Can a broken pin damage the plate?
A worn/broken pin left unreplaced can damage the seat and press quality; early replacement protects the plate.
Can I switch to a magnetic pin during replacement?
Yes, we upgrade the classic pin plate to a magnetic pin system (retrofit), manufactured to match your brand and model exactly.
