OverviewThe Injection Molding Compounder from IMC Technology integrates continuous compounding based on extrusion with discontinuous injection molding. The system enables inline compounding inside the injection molding cycle for a wide range of compounds, reducing material handling and offering significant material-cost savings. A material accumulator decouples the continuous extrusion flow from the injection/holding phases, while a transfer valve and the ShotPot concept manage transfer and shot formation.
Key features- Inline compounding combined with injection molding (continuous extrusion + discontinuous injection)
- Modular twin‑screw extruder design configurable to specific applications
- Material accumulator to temporarily store melt during injection and holding phases
- Transfer valve separating low‑pressure extruder side and high‑pressure shot pot during injection
- ShotPot injection unit enabling combined transfer of fresh and stored melt for consistent shot formation
- Suitable for almost all compounds, including filled and fiber‑reinforced materials
Benefits- Reduced material procurement and handling costs
- On‑demand formulation and inline customization of material properties
- Sustainable, material‑friendly production by replacing multi‑stage workflows
- Protection of formulation know‑how through integrated processing
Process components and technologies- Twin‑screw extruder for compounding: co‑ or counter‑rotating options, modular process units, high melting and compounding performance
- Gravimetric single‑component dosing (loss‑in‑weight): precise feed for matrix, fillers and reinforcements; dosing unit matched to raw material types
- Material accumulator: interface between continuous extrusion and discontinuous injection; optimized flow channels; can be integrated into machine control or run independently
- ShotPot injection unit: piston‑based injection (instead of screw) with wide shot weight range, consistent shot control and high stroke utilisation
- Fully integrated control system synchronising dosing, extrusion, accumulator and injection with injection moulding process control
Applications / Use cases- Inline compounding where integration reduces material handling and costs in injection moulding production
- Processing filled and reinforced compounds including fibre‑reinforced and lightweight materials
- Rapid change of formulations or on‑demand customization of part material properties
