Clay extruders for studio pottery don't carry a tonnage rating the way industrial pugmills and hydraulic dies do. The Scott Creek Pottery 4″ Wall Mount Clay Extruder wins for most studios on clay capacity and die-change speed, the handheld Super Duper Clay Gun Extruder wins for occasional handles and small runs, and pairing the wall mount with its Expansion Box wins for daily high-volume production.
Searches for "clay extruders ranked by tonnage" usually come from potters comparing spec sheets the way they'd compare a hydraulic press or a pugmill. Wall-mount and hand-held studio extruders don't work that way — they're lever and screw systems rated by clay capacity in pounds, not tons of ram force. If you run daily production pottery out of a home or shared studio, capacity per load and die-change speed matter more than a force figure no manufacturer publishes for this equipment class.
Prokilnsupply carries the Scott Creek Pottery extruder lineup as part of a kiln-only catalog, so the ranking below sticks to what's actually documented: clay capacity, barrel material, die compatibility, and whether a unit can scale up with an add-on. No invented PSI numbers, no guessed tonnage — just the specs that show up on the product pages.
“Tonnage is a pugmill and hydraulic-press spec. Studio wall-mount extruders are rated by clay capacity and leverage, not tons.”

| Extruder | Best for | Standout feature | Key limitation |
|---|---|---|---|
| Scott Creek Pottery 4″ Wall Mount Clay Extruder | Studio production | 8-9 lb clay capacity, removable barrel cap for fast die swaps | Fixed to a wall, not portable |
| Scott Creek Pottery Super Duper Clay Gun Extruder | Handles and small runs | Hand-held, zero installation | Small barrel limits batch size |
| Scott Creek Pottery 4″ Wall Mount + Expansion Box | High-volume production | Added barrel volume on the same die system | Requires the base unit first |
The 4″ Wall Mount Clay Extruder is Scott Creek Pottery's most popular model, built around an all-aluminum barrel and a clay capacity of 8-9 lbs per load. The barrel cap comes off without tools, so swapping between a hollow die and a handle die takes seconds instead of minutes mid-session. It's a fixed-mount unit, which means you're committing wall space to it, not a bench you can move around.

The Expansion Box bolts onto the base 4″ Wall Mount unit and adds barrel volume, letting a studio extrude larger forms without switching to a second machine. It keeps the same die-change mechanism as the base unit, so there's no new system to learn — you're scaling the tool you already own.

The ranking runs on clay capacity, die-change speed, barrel durability, and expansion path — not tonnage, because none of these lever-based units publish a force rating. The 4″ Wall Mount Clay Extruder scores highest on documented capacity (8-9 lbs) and die-change design. The Super Duper Clay Gun wins on portability alone. The Expansion Box combination wins on scale, since it's the only path to more volume without buying a second wall unit.
Pick the Scott Creek Pottery 4″ Wall Mount Clay Extruder if you're setting up a home or shared studio and want one machine that handles coils, handles, and tile stock without daily strain. Pick the Super Duper Clay Gun Extruder if you only need occasional handles and don't want to mount anything to a wall. Pick the 4″ Wall Mount with Expansion Box if you're already extruding daily and the base barrel is running out of volume mid-session.

What's the best clay extruder for a home studio in 2026?
The Scott Creek Pottery 4″ Wall Mount Clay Extruder is the best all-around pick for a home studio in 2026, with 8-9 lb clay capacity and fast die changes. It's the right size for coils, handles, and small tile runs without needing a second machine.
Is there a tonnage rating for pottery clay extruders?
No — studio wall-mount and hand-held clay extruders don't publish a tonnage or PSI rating. That spec applies to hydraulic presses and industrial pugmills, not lever-based studio extruders like the Scott Creek Pottery line.
How much clay capacity do I need in a wall-mount extruder?
For most studios, 8-9 lbs per load, the capacity of the Scott Creek Pottery 4″ Wall Mount Clay Extruder, covers handles, coils, and short tile runs without constant reloading. Production studios extruding daily may need the Expansion Box to add barrel volume.
What's the difference between a hand-held clay gun and a wall-mount extruder?
A hand-held clay gun like the Super Duper Clay Gun Extruder needs no installation and suits occasional small runs, while a wall-mount extruder is fixed in place but holds more clay per load and changes dies faster. Studios doing daily extrusion work benefit more from the wall-mount design.
Can I add more capacity to my Scott Creek Pottery extruder later?
Yes — the 4″ Clay Extruder Expansion Box bolts onto the base 4″ Wall Mount unit to add barrel volume without buying a second extruder. It keeps the same die-change mechanism as the base unit.
What dies fit a 4″ versus 5″ clay extruder?
4″ and 5″ Scott Creek Pottery extruders each use their own matched die family — a 4″ die won't fit a 5″ barrel and vice versa. Die kits come in 6-piece, 8-shape, and 24-piece sets depending on how many hollow and handle profiles you need.
Do I need an extruder if I already have a pug mill?
A pug mill recycles and de-airs clay; a clay extruder shapes it into coils, handles, or hollow forms. Most production studios run both — check the guide on pug mills for clay recycling studios if you're deciding which to buy first.
The blank aluminum die is the most overlooked item in the Scott Creek Pottery lineup. It's an unshaped piece of aluminum you cut a custom profile into yourself with a jeweler's saw, which turns one die slot into a shape library instead of a fixed round or handle profile. Most studios never touch it and stick to the stock round dies — that's the gap worth closing if you're extruding daily in 2026 and want a house shape nobody else's mugs have.
