Choosing plastics rubber processing machinery is difficult when closely related single-screw extruders cover very different setup needs. The key decision is not simply the listed price: decide whether you need a machine with stated drive and output figures, an extrusion assembly intended for a separately selected motor, or a 3D-filament-oriented component with particular dimensions.
Quick take
The Single Screw Extruder Plastic Heating Extrusion Machine 110V 0.1-2kg/h Dia 1 is the machine-focused choice, with its own stated motor power and output capacity. The 3D Filament Single Screw Extruder 110V 3 Heating Coil Plastic Extrusion Machine and the USD 161.31 3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine are more assembly-oriented, as both descriptions specify that the motor is not included. The USD 149.99 version of the latter title is the lowest listed-price option and identifies a Three Heating Coil selection.
Listed price comparison
| Extruder option | Listed price | Relative listed-price position |
|---|---|---|
| Single Screw Extruder Plastic Heating Extrusion Machine 110V 0.1-2kg/h Dia 1 | USD 1,943.70 | |

| 3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine - Three Heating Coil version | USD 149.99 |
The listed-price range is wide, from USD 149.99 to USD 1,943.70, so match the equipment role to the scale and structure of your intended extrusion setup.
Decision matrix
- Need stated output capacity for a single-screw machine: Choose the Single Screw Extruder Plastic Heating Extrusion Machine 110V 0.1-2kg/h Dia 1.
- Planning around named polymers and a selected drive requirement: Choose the 3D Filament Single Screw Extruder 110V 3 Heating Coil Plastic Extrusion Machine.
- Prioritizing stated screw and nozzle geometry: Choose the USD 161.31 3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine.
- Starting with the lowest listed price: Choose the USD 149.99 3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine.
Product notes
Single Screw Extruder Plastic Heating Extrusion Machine 110V 0.1-2kg/h Dia 1
This TECHTONGDA single-screw machine is the choice for a project centered on its stated 25mm screw, 16:1 LD ratio, 0-25 r/min speed range, 250W motor power, and 400W heating power. Those parameters make it a more defined starting point for plastic extrusion processing than the accessory-style alternatives here. It also names compatible consumables including PEEK, PCL, ABS, PLA, PETG, TPU, and TPE. Its important limitation is that completing plastic-product processing calls for auxiliary equipment such as moulds, cooling equipment, a hauling machine, or winding or cutting equipment.
3D Filament Single Screw Extruder 110V 3 Heating Coil Plastic Extrusion Machine
Choose this extruder when small-batch testing, experimental research, or 3D filament extrusion molding is the goal. It names a broad material set that includes PE, PP, PS, PVC, POM, PA, PC, ABS, and PET, and its 45# steel screw is described for temperatures up to 300°C/572°F. The assembly also includes three 200W, 110V ceramic heating coils and a hopper. The tradeoff is that the motor is not included: the stated requirement is a 50 RPM, 200W motor with 15Nm torque, with coupling alignment part of the assembly process.
3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine - 20mm Screw Version
This USD 161.31 version suits shoppers who need clearly stated component geometry for an extrusion build. It specifies a 20mm screw diameter, 330mm screw length, 30mm screw-sleeve outer diameter, 28mm inlet diameter, and a 2.5mm nozzle aperture. Heating is described as three 200W coils, giving it a defined heating layout for a 3D-filament-focused assembly. Its limitation is straightforward: the motor part is not included. This option is therefore better aligned with a setup where the drive component is selected separately rather than one requiring a motor-equipped extruder body.
3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine - Three Heating Coil Version
This is the lowest listed-price choice in the comparison and may fit a shopper whose project aligns with its Three Heating Coil selection. Its attributes identify compatible brand and compatible model as Universal, which can be useful when those designations are central to how you are organizing an extrusion setup. It is also marked as new and identifies China as its country of origin. The concrete constraint is its stated 2.5mm filament diameter: use this option when that listed diameter matches the intended filament-focused application, rather than treating it as a general-purpose dimensional specification.
Final recommendation by use case
Choose the TECHTONGDA machine when your priority is a single-screw extruder with stated machine-level drive and capacity parameters. For assembly-oriented 3D-filament projects, select the USD 169.00 model when material and drive requirements are the main focus, or the USD 161.31 version when screw and nozzle dimensions guide the decision. Pick the USD 149.99 version when its listed 2.5mm filament diameter and Universal compatibility designations suit the planned setup.
