Quick Take
If you're shopping for plastics and rubber processing machinery, the first decision is whether you need a bench tool or a full extrusion setup. The Square Pad Plate Gasket with Rubber Feet Jewelry Gold Tool Processing Equipment is a small iron anvil with a rubber pad for jewelry and metalwork, not a plastic extruder. The two 3D Filament Single Screw Extruder listings are compact single-screw extruders for melting plastic pellets into filament. The Single Screw Extruder Plastic Extrusion Processing Machine 110V Speed Adjustable is the largest and most expensive listing here, designed to be the center of a small extrusion line. Listed prices run from $25.23 up to $1,999.50.

Product Notes
Square Pad Plate Gasket with Rubber Feet Jewelry Gold Tool Processing Equipment
At $25.23, this is the lowest listed price in this collection. The listing describes a solid iron surface with a rubber pad, about 6.3 x 6.3 x 1.2 cm, designed for jewelry and gold tool processing, engraving, grinding, and forging. Choose it if your work is small, detailed metal shaping rather than polymer extrusion. The practical limitation is that it is not a plastics or rubber processing machine, so it can't melt pellets or produce filament. It is best treated as a bench accessory for crafters, jewelers, and artisans.
3D Filament Single Screw Extruder (Heating Coil)
This version of the 3D Filament Single Screw Extruder is priced at $158.86, making it the lower-priced option among the two filament extruders here. Its listed specs include a 20mm screw diameter, 330mm screw length, 28mm inlet diameter, 2.5mm nozzle aperture, and 200W*3 heating coils. Choose it for experimental filament work when you already have a motor and drive arrangement, because the listing notes that the motor part is not included. The default 2.5mm nozzle is another spec to plan around.
3D Filament Single Screw Extruder (Three Heating Coil)
This version of the 3D Filament Single Screw Extruder is listed at $227.99 and adds an aluminum alloy heat sink, 200W ceramic heating coils, and a 45-gauge steel screw to the single-screw design. The attributes also show a three-heating-coil configuration. It is described as compact enough for experimental research and small-batch testing. The same caveat applies: the motor part is not included, and the default nozzle is 2.5mm, with a 1.75mm nozzle offered as a separate purchase. This is the more feature-rich bench-top option if you want ceramic coil heating in a small package.
Single Screw Extruder Plastic Extrusion Processing Machine 110V Speed Adjustable
At $1,999.50, this is the highest-priced listing and the one with the most complete set of extrusion parameters. It has a 25mm screw diameter, 16:1 L/D ratio, 0-25 r/min speed range, 250W motor, and 400W heating power. The description says it is suitable for extrusion of PEEK, PCL, ABS, PLA, PETG, TPU, TPE, and other common 3D printing consumables. The trade-off is that it is described as the mother machine of a plastic extrusion processing line, meaning you will still need auxiliary equipment such as moulds, cooling, hauling, winding, or cutting machines to finish products.
Final Recommendation by Use Case
Match the machine to the job. For jewelry crafting and fine metalwork, the Square Pad Plate Gasket with Rubber Feet Jewelry Gold Tool Processing Equipment at $25.23 is a simple, low-cost bench addition. For a compact filament extruder at the lower listed price among the two extruder listings, the 3D Filament Single Screw Extruder (Heating Coil) at $158.86 is the direct choice. If you want ceramic heating coils and a heat sink in a bench-top frame, the three-heating-coil version at $227.99 is the better fit. For a production-minded single-screw extruder that can process common 3D printing materials and accepts surrounding auxiliary equipment, the Single Screw Extruder Plastic Extrusion Processing Machine 110V Speed Adjustable at $1,999.50 is the serious choice.
