If you’ve ever walked through a packaging shop, a fabric prototype studio, or a custom gaskets workshop, you’ve probably stood beside a feeder die cutter with partial stripping in action. That machine whirs smoothly, feeds raw material in a continuous strip, cuts out precise shapes, and then strips away the scrap around the finished part—all in one go. For years, I’ve talked to operators and production managers who ask the same question: How thick of a material can this type of cutter actually handle? The answer isn’t a single number, and as a supplier who’s built and tested these machines for 12 years, I’m here to break down what really determines that maximum thickness, what our own equipment is capable of, and what you need to know before you invest in one for your shop. Feeder Die Cutter with Partial Stripping
Let’s start with the basics, because partial stripping is the feature that makes this cutter different from a standard die cutter. A standard flatbed die cutter just cuts through material; a feeder die cutter with partial stripping adds a second step: it cuts through the top layer of material, leaves the bottom intact, and then pulls away the waste around the final part—without touching the back side. That partial cut is critical for thin materials like paper, vinyl, and even some thin foam, but it also puts unique pressure on the machine’s components when you start working with thicker stock. The biggest mistake I see buyers make is assuming “thicker = better” or that all partial stripping die cutters are equal. The truth is, maximum thickness is a balance between die design, stripping mechanism, feeder tension, and even the type of material you’re working with.
First, let’s talk about the core components that limit how thick a feeder die cutter with partial stripping can cut. The main part is the die itself. These dies are usually made of steel rule, bent into the shape you need, with a sharp cutting edge. The height of that rule is non-negotiable for thickness: standard steel rule comes in heights from 18 points (about 0.018 inches, or 0.457 mm) up to 24 points (0.024 inches, 0.61 mm) for most standard dies. But if you’re working with thicker materials, you can get custom rule up to 36 points (0.036 inches, 0.914 mm), and even 42 points (0.042 inches, 1.067 mm) for heavy-duty dies. But here’s the catch for partial stripping: the rule’s height isn’t just for cutting. It has to stick high enough to cut through the top of your material, but leave enough of a “land” at the bottom of the rule to grab the waste strip without cutting through the backing layer. If the material is too thick, that land is gone—so the cutter either cuts all the way through, or can’t grip the waste to strip it. That’s a showstopper. You could have a die that cuts thick material, but if it can’t strip the scrap without damaging the finished part, it’s useless.
Next, the stripping mechanism. Partial stripping relies on two parts: a stripper plate, which is a flat metal plate that sits just above the material after the die cuts, and a vacuum or pressure system that pulls the waste away from the finished part. For thin materials, the stripper plate can be set very close to the die without interfering. But as material thickness increases, the gap between the die cutting edge and the stripper plate has to get bigger—otherwise, the stripper will bend the material or knock the finished part out of alignment. That gap, called the “stripper clearance,” is a key specification. Most budget feeder die cutters with partial stripping have a maximum stripper clearance of around 0.05 inches (1.27 mm). That means they can handle a maximum material thickness of roughly 0.04 inches (1.016 mm), leaving 0.01 inches of clearance for the stripper. But our premium line of partial stripping feeder dies uses an adjustable stripper plate, so we can get a clearance of up to 0.08 inches (2.03 mm) without sacrificing grip, which bumps that maximum material thickness up to 0.07 inches (1.778 mm). But again, this isn’t a one-size-fits-all number. If your material is foam that compresses easily, you can go a little thicker because the compression reduces the actual distance the die has to cut. If it’s rigid, like cardboard or thin plastic sheet, you have to stay closer to the stripper clearance limit.
Feeder tension is another often-overlooked factor. A feeder die cutter works by pulling the material strip through the machine in continuous motion, usually at speeds between 10 and 100 feet per minute, depending on the model. For thin, flexible materials, low tension works fine. But when you’re feeding thick, rigid material, you need higher tension to keep the strip straight so the die cuts evenly every time. If the tension is too low, the strip can shift during cutting, leading to misaligned cuts that make partial stripping impossible. But too much tension can warp the material, especially thin rigid stock, or cause it to tear before it even reaches the die. For our heavy-duty partial stripping machines, we’ve calibrated the feeder system to handle up to 0.06 inch thick rigid stock at 60 feet per minute, without warping or tearing. I’ve had customers tell me they bought a cheap machine that claimed to cut 0.1 inch thick material, but their problem wasn’t the die—it was the feeder, which couldn’t pull the thick stock straight without bending it. That’s a common pitfall.
Now, let’s get to the numbers, because that’s what most of you are here for. Over 12 years of building and testing feeder die cutters with partial stripping, we’ve done hundreds of material tests, and we’ve compiled a clear range of maximum thickness based on our different machine lines. Our entry-level model, designed for small jobs and thin materials like tissue paper, thin vinyl, and 12pt cardboard, has a maximum recommended material thickness of 0.025 inches (0.635 mm). This is perfect for startups or small shops that only work with light packaging or craft materials. Our mid-range model, the workhorse for most printing shops, gaskets producers, and prototype makers, has a maximum thickness of 0.05 inches (1.27 mm). We tested this with materials like 20pt cardboard, thin EVA foam, 0.04 inch PET film, and even 0.05 inch neoprene, and all had clean partial cuts and consistent stripping. Our heavy-duty line, which we launched in 2021, is built for high-volume production and thicker industrial materials. That model can handle up to 0.08 inches (2.03 mm) of material. We tested it with 30pt corrugated board, 0.07 inch cross-linked polyethylene foam, 0.08 inch rigid PVC sheet, and even thin rubber gasketing, and every test run produced parts with clean edges and no torn backing layers.
But here’s the thing: those numbers are for “typical” materials. Every material has different properties, and that changes the maximum thickness. For example, foam is compressible, so a 0.08 inch thick EVA foam compresses by about 10% when the die hits it, so the actual cut depth needed is less, meaning you can go a tiny bit thicker—up to 0.09 inches (2.286 mm) for soft, compressible foams. But rigid materials, like acrylic or hard cardboard, don’t compress at all, so you have to stick closer to the 0.08 inch limit. Even within the same material category, there’s variation. A 20pt cardboard from one manufacturer might be thicker and stiffer than another, so you’d need to adjust your die rule height and stripper clearance accordingly. We always tell customers to test their specific material with a sample machine before committing to a purchase, because generic numbers don’t account for material variability.
I also want to address a common myth I hear a lot: “If I want to cut thicker material, I can just use a heavier die or upgrade the blade.” That’s only partially true. A heavier die can apply more force, which is good for cutting thick rigid materials, but it also increases the chance that the die will damage the stripper plate or bend the material during stripping. We’ve had customers try to use a 50 point die (which is 0.05 inches tall) on a material that was only 0.04 inches thick, and it cut all the way through the backing layer, so stripping was impossible. The extra blade height was too much for partial stripping, even though the die could cut through the full material. So blade height is just as important as blade thickness for partial stripping, not just the cutting force.
Another factor that affects maximum thickness is the cut shape. If you’re cutting simple, straight shapes like circles or squares, you can go thicker than if you’re cutting complex shapes with lots of tight curves and internal cuts. For example, a simple 4 inch diameter circle can be cut from 0.08 inch thick material on our heavy-duty machine, but a shape with a 0.5 inch internal circle and multiple small tabs might max out at 0.05 inches (1.27 mm) thick. The tight curves mean the waste strip is narrower and more fragile, so it’s easier to tear during stripping if the material is too thick. That’s why we always advise customers to share their cut design when asking about maximum thickness—we can adjust the die and stripper setup to work for that specific shape.
I’ve seen this play out with a recent customer, a medical device parts manufacturer who needed to cut custom gaskets from 0.06 inch thick silicone rubber. They initially went with an entry-level feeder die cutter that claimed to cut 0.07 inch thick material, but when they tested the silicone, they found it couldn’t strip the waste without tearing the gasket’s sealing surface. They came to us, and we adjusted the stripper clearance on their mid-range machine, used a custom 38 point die (0.038 inch rule height) instead of the standard 24 point, and recalibrated the feeder tension. The result? They now run 500 parts a minute, no torn gaskets, and consistent partial cuts every time. That’s a perfect example of how maximum thickness isn’t just a machine number—it’s a combination of machine specs, die design, and material properties.
If you’re in the market for a feeder die cutter with partial stripping, the worst thing you can do is buy a machine based solely on the maximum thickness number it advertises. A lot of low-cost manufacturers overstate their thickness ratings, often using tests with very simple shapes and soft, compressible materials that aren’t what you’ll be cutting. Our heavy-duty line’s 0.08 inch rating is for rigid, 2 inch square parts with straight edges. If you’re cutting thin foam, you can go thicker, but if you’re cutting complex shapes in rigid plastic, you might need to stay under that number.
At the end of the day, the maximum thickness of a feeder die cutter with partial stripping is a balance of four key factors: your die’s rule height, the stripper mechanism’s clearance, feeder tension, and the properties of your specific material and cut design. For small craft or light packaging, you’ll be fine with a machine that handles up to 0.03 inches (0.762 mm). For high-volume gaskets or corrugated parts, our mid-range 0.05 inch (1.27 mm) model is ideal. For heavy industrial materials and large, simple shapes, our heavy-duty line’s 0.08 inch (2.03 mm) maximum will work for most applications.
