Some of the best customers I work with are the ones who are tired of depending on someone else. That was exactly the situation when Mikhail, who runs a floor-cleaning equipment company in Ukraine, contacted me. His machines rely on natural-rubber sealing gaskets, and for years he bought those seals from an outside supplier. The price was high, delivery was late, and quality was inconsistent. So his company made a smart decision: buy a rubber gasket cutting machine and produce the gaskets themselves. This case study walks through how we proved the machine on his own material first, then configured it around his production line.
Mikhail's company builds floor-cleaning equipment, and one of the components in those machines is a natural-rubber sealing gasket. He runs many different gasket styles — the sort of varied, small-batch mix that gives outside suppliers every excuse to charge a premium and miss deadlines. High prices, slow delivery, and unstable quality had become a real drag on his production. Bringing gasket cutting in-house was the way out.
Mikhail didn't want promises — he wanted proof. Before discussing price, specs, or anything else, he asked to run a real sample cut using his own material and his own cutting graphics. If the results met his requirements, then we would talk terms. I respect that approach completely; a real test cut tells a buyer more than any brochure.
So we set it up. Mikhail had his rubber-sheet supplier in Thailand ship the rubber board directly to us, and he sent over his cutting files. We cut the samples exactly to his drawings on our CNC oscillating knife cutting machine, and we recorded both a full cutting video and close-up detail photos so he could inspect everything remotely. He was very satisfied with the results overall. Three things stood out:
Simple operation. You import the design file and the machine cuts the finished part directly. That workflow is especially well suited to Mikhail's need for many styles in small batches — no dies, no tooling changeover, just load the next file.
Excellent cut quality. The cut faces came out flat, smooth, and perpendicular — clean edges with no dragging or fuzzing.
High precision. We measured the finished gaskets against his design dimensions, and the deviation was very small.
The sample test is the single most persuasive step in a purchase like this, which is why I recommend every serious buyer ask for it. If you want to send your own rubber and drawings, our gasket cutting machine line is set up to run test cuts exactly the way we did for Mikhail.
With Mikhail satisfied by the samples, we moved on to the machine details.
Based on his material dimensions, we set the machine at a 1.6m × 2.5m working area. Because his rubber comes as roll material, Mikhail chose the automatic feeding option so the machine pulls the material forward on its own. Rubber roll is heavy, and dragging it forward by hand is hard, tiring work — the auto-feed system removes that strain and keeps the feed even, which protects cut accuracy on longer runs.
Mikhail asked which design software and file formats our gasket cutting machine accepts. The answer: it supports most mainstream CAD design software. That includes 2D design tools like AutoCAD, CorelDRAW, and Adobe Illustrator, as well as 3D design software like SolidWorks and Pro/E. In practice that means whatever your engineers already draw in, you can bring straight to the machine without redrawing.
He also asked how we fix the material during cutting. Our gasket cutting machine uses vacuum suction to hold the material. The worktable is an aluminum bellows structure connected by piping to a vacuum pump; when the pump runs, it evacuates the air inside the aluminum bellows to create negative pressure, which grips the material firmly. Just as important, our vacuum table has zoned suction — it can concentrate suction into a designated area so that even small pieces stay locked down solidly. For Mikhail's varied gasket styles, where some parts are small, that zoned hold-down is what guarantees clean, accurate cuts across every size.
Mikhail's parts are natural rubber, but the same machine handles the full range of elastomer sealing materials — which matters if your product line uses more than one compound. Here is how the CNC gasket cutting machine performs across the materials buyers ask me about most.
Natural rubber (NR) gaskets. Mikhail's material — soft, resilient, and easy to hold flat under vacuum. The oscillating knife shears cleanly through NR sheet without dragging, leaving the flat, perpendicular edge his cleaning-equipment seals need.
Nitrile rubber (NBR) gaskets. NBR is the workhorse of oil- and fuel-resistant sealing — pump seals, hydraulic components, automotive and machinery gaskets. Because NBR sheet can be firm, the oscillating knife's high-frequency cut is ideal: it slices through without heat and leaves a smooth, burr-free face, which is exactly what you want on a sealing surface.
Silicone rubber gaskets. Silicone is soft and tacky, which makes die-cutting messy and hand-cutting inconsistent. On our machine, the multi-zone vacuum table holds the stretchy sheet flat while the blade cuts precise contours — perfect for food-grade, high-temperature, and electronics sealing gaskets.
EPDM gaskets. Common in weather, water, and steam sealing. EPDM cuts cleanly with the same die-less workflow, so you can switch from NBR to EPDM to silicone just by loading a different file — no new tooling.
Other sealing sheet. The same machine also handles silicone foam, sponge rubber, cork-rubber, and fiber gasket sheet by adjusting the tool and cut settings, giving one line the flexibility to cover a varied seal catalog.
Because the process is die-less, every one of these materials runs from the same imported CAD file — so a many-style, small-batch operation like Mikhail's can switch compounds and shapes in minutes. That die-less flexibility is the core reason rubber gasket cutting machines are replacing traditional die cutting.
Mikhail's need — many styles, small batches — is exactly the scenario where the buy-vs-make math tips decisively. Here is the honest comparison I gave him.
Pros: Light-asset operation. No one-time capital outlay for a machine, and no need to staff an operator.
Cons: The premium on small-batch processing is severe, and overseas processing fees are expensive to begin with — so the long-term total cost is very high. Custom parts can't be pre-stocked by the supplier, so every order runs on a slow lead time. On top of that, the drawing-confirmation and back-and-forth communication steps eat up a lot of additional time. This is precisely the price/delivery/quality trap Mikhail was already stuck in.
Pros:
Extremely responsive. Whatever spec the production line is short on, you can deliver it on-site within half an hour — production schedule never slips.
Lower long-term cost. Our gasket cutting machine is not expensive; the premium you pay on ordered finished gaskets in a single year is enough to buy the machine outright. Over the long run, that saves a large amount of money.
Confidentiality. New products you develop stay in-house, with no risk of your drawings leaking to an outside supplier.
Cons: A one-time capital investment to buy the machine, plus one operator to run it and organize finished parts.
For a maker like Mikhail — high style variety, small runs, and a real cost of downtime — the machine pays for itself and then keeps paying.

I did for Mikhail exactly what I offer every serious buyer: cut his material, to his drawings, on video, and let the samples decide. If you make natural-rubber, silicone, or other sealing gaskets and you're tired of high prices, slow delivery, and unstable quality from outside suppliers, send my team your rubber-sheet specs and cutting files — we'll run a sample cut and configure a rubber gasket cutting machine around your material size and production line.
