HP-CRTM Resin Injection System | Composite Panels
High-pressure resin metering and surface injection coordinated with compression-RTM tooling and press movement.
Fast-Cycle High-Pressure Compression RTM for Large Structural Panels
High-pressure resin metering and surface injection coordinated with compression-RTM tooling and press movement.
High-pressure resin metering and surface injection coordinated with compression-RTM tooling and press movement.
Resin preparation, metering/mixing skid, tool injection interfaces and coordinated controls. Press, preform handling, mold and material validation are agreed external scope.
The stated 12–20 MPa is the metering/impingement circuit, distinct from cavity pressure. Press approach, pressing stroke, resin wet-out and the complete molding cycle are specified separately for the chosen resin, preform and tool.

Material Flow and Working Principle
Continuous Preform Positioning & Deep Cavity Evacuation
The multi-axial carbon fiber preform is loaded onto the heated bottom mold; the press closes to a calibrated 1.0 mm micro-gap while vacuum skids draw cavity pressure down to 0.05 kPa.
Micro-Gap Low-Resistance Resin Injection
The high-pressure impingement mixing head dispenses fast-curing epoxy at 18.0 MPa, spreading liquid resin rapidly across the open surface of the carbon fabric without fiber distortion.
High-Speed Vertical Compaction (HP-CRTM)
As injection terminates, the press executes rapid downward clamping at 300 mm/s under 3,000 tons of force, driving the resin through the thickness direction across the 3.5 m² surface.
Isothermal High-Pressure Curing
The part cures in-mold at 130°C under continuous 15 MPa hydraulic pressure for 90 seconds, with integrated dielectric sensors monitoring resin conversion in real time.
Robotic Demolding & Shuttle Transfer
Hydraulic cylinders crack the mold; automated end-effectors lift the hot composite tray, transferring it to edge-trimming fixtures every 120 seconds.

Key Equipment Features
Resin preparation, metering/mixing skid, tool injection interfaces and coordinated controls. Press, preform handling, mold and material validation are agreed external scope.
Through-Thickness Penetration
Micro-gap surface distribution and through-thickness compaction are coordinated for the selected preform and tool. Fiber displacement is inspected on the part; zero fiber wash is not guaranteed.
300 mm/s Fast Press Compaction
The supplied 300 mm/s press-compaction reference is an agreed press interface. A sub-120-second complete cycle additionally depends on resin cure, handling and line balance.
3.5 m² Large-Area Scalability
Supplied configuration reference: Capable of producing oversized battery trays (2.2 m× 1.6 m) with uniform thickness within ±0.1 mm. Actual capability requires material and tooling validation.
35% Weight Reduction vs Aluminum
Supplied configuration reference: Consolidates continuous carbon fabrics into structural shells replacing heavy aluminum die-castings. Actual capability requires material and tooling validation.
