Choosing between these four plastics processing machines starts with a simple question: are you molding parts, drying resin, or extruding material? The group spans a used pneumatic press, a new hopper dryer, and a screw extruder, with prices from $810.28 to $2,097.15. None of these machines do exactly the same job, so the right pick depends on your workflow and the condition you are willing to accept.
Quick take
- The Tasco-Tesco Megatron 110A is a used semi-automatic pneumatic injection press with a 1 oz shot size.
- The intbuying hopper dryer is a new 50kg dryer for removing moisture from plastic pellets.
- The TECHTONGDA SJ25 is a new automatic screw extruder for small-scale filament and plastic extrusion.
- The Iasco Megatron 110a is a used pneumatic press with manual actuation and an included practice mold tool.

Decision matrix
| Product | Good for | Consider if |
|---|---|---|
| Megatron 110A Pneumatic (Tasco-Tesco) | Semi-automatic benchtop injection with a 1 oz shot | You want a used US-made press with pneumatic control |
| INTBUYING Hopper Dryer | Drying resin before molding | You already have a molding machine and need a 50kg dryer |
| TECHTONGDA SJ25 | Small-scale extrusion and filament production | You need a 110V automatic screw extruder |
| Megatron 110a (Iasco) | Press work with a practice mold tool | You want a used pneumatic press with a 2-ton mold clamp |
Product notes
Megatron 110A Pneumatic Injection Molding Machine (Tasco-Tesco)
This used press is a semi-automatic benchtop vertical machine with pneumatic control, listed at $899.99. The 1 oz shot size and vice-type mold clamp fit small part runs and prototyping. It carries a U.S. origin and shows only minor wear in its used condition, so you are buying a working used machine rather than new equipment. The main limitation is that it is used, so you are accepting pre-owned condition. If you need a ready-to-work pneumatic press without paying for a brand-new unit, this is the option to evaluate.
Injection Molding Machine Plastic Hopper Dryer (intbuying)
The intbuying option is a new 50kg hopper dryer with a 110lbs capacity, 220V input, and 4.5kW heating, listed at $810.28. Its job is to remove moisture from plastic raw materials before they go into an injection molding machine. Stainless steel contact parts and a temperature controller that keeps the warm air within a narrow ±3 degrees are the concrete features. The limitation is that this is a dryer, not a molding press or an extruder, so it only works as part of a larger setup. For anyone with an existing molding line that needs a fresh drying step, this is the one to consider.
Single Screw Extruder SJ25 (TECHTONGDA)
The TECHTONGDA SJ25 is listed at $2,097.15, making it the highest-priced option in this group. It is an automatic vertical single screw extruder that runs on 110V and processes roughly 0.1-2kg per hour. The material list covers PEEK, PCL, ABS, PLA, PETG, TPU, and TPE, which makes it a fit for 3D printing consumables and small extrusion work. The downside is that auxiliary equipment like cooling, hauling, and winding is needed to complete a production line, so this is a component machine rather than a complete standalone press.
Megatron 110a Plastic Injection Molding Machine (Iasco)
This used Megatron 110a appears at $1,399.00 and adds a practice mold tool to the package. It is a pneumatic injection press with a 2-ton mold clamp, 0-150 psi input, a 0-550°F temperature controller, and a 1 oz shot size. It operates on 110V and is marked as manual actuation, so the machine gives you direct control over the molding process. The tradeoff is that it is used and manual, so you trade some automation for a lower price than a comparable new automatic extruder and get a spare practice mold tool included.
Final recommendation by use case
If your priority is a US-made semi-automatic pneumatic press and you want the lowest listed price, the Tasco-Tesco Megatron 110A is the direct match. If you already have a press or extruder and only need to dry material before molding, the intbuying hopper dryer is the simplest add-on. If you are making filament or extruding small batches of common 3D printing materials, the TECHTONGDA SJ25 is the extruder to focus on. And if you want a used pneumatic press with a practice mold tool and a 2-ton clamp, the Iasco Megatron 110a is the one to evaluate.
