6 top-level parts · 18 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Plasticizing Barrel 3 parts | 1× | Nitrided steel cylinder that contains the screw and holds the melt under pressure. |
| 2 | Reciprocating Screw 3 parts | 1× | Single-flight screw with feed, compression, and metering zones plus a non-return valve. |
| 3 | Injection Nozzle 3 parts | 1× | Heated tip that seals against the mold sprue bushing and gates the melt. |
| 4 | Injection Cylinder | 2× | |
| 5 | Screw Rotation Drive 3 parts | 1× | Hydraulic motor that turns the screw to plasticize the next shot. |
| 6 | Injection Carriage 2 parts | 1× | Sled that advances the whole unit so the nozzle seats on the mold. |
