Product Overview
The HF‑RIM‑PU‑2A2B is a high‑capacity RIM system delivering precise two‑component metering and high‑pressure mixing for carbon, glass, and fiber‑reinforced polyurethane parts.
This advanced RIM‑PU molding machine is engineered for reaction injection molding of fiber‑reinforced composites, covering a wide range of industries including automotive (interior/exterior trims), agricultural machinery components, water sports equipment, and large‑scale building structures. It features independent temperature‑controlled tanks (200L/300L optional) with circulation stirring, a high‑pressure mixing head that ensures homogeneous material blending, and a PLC‑based control system with multi‑formula storage for quick changeover. The pouring rate is adjustable from 100 to 2000 g/s, enabling both delicate precision parts and large‑sized integral components to be produced on the same platform. Mold negative pressure venting combined with high‑pressure homogenization guarantees bubble‑free, high‑strength parts. The cleaning system uses high‑pressure circulation and air purging to minimize maintenance.
Production Workflow
Material Preparation
Load polyether and isocyanate into separate tanks (200L/300L), set temperature (25‑45℃) and start circulation stirring.
Recipe Selection & Ratio Setting
Choose stored recipe on touch screen; adjust mix ratio (100:90‑110) and flow rate (100‑2000 g/s) per part requirement.
High‑Pressure Mixing & Injection
Pump components to mixing head at 150‑200 bar; impact mixing creates homogeneous resin; inject into mold with negative pressure venting for void‑free fill.
Demolding & Cleaning
After curing, demold part; run high‑pressure circulation cleaning and air purge to prepare head for next batch.

Key Advantages
Six core benefits that make this machine ideal for flexible, high‑quality production of fiber‑reinforced polyurethane components across multiple industries.
High‑Pressure Homogeneous Mixing
Ensures compact and stable composite structure, delivering consistent mechanical properties for both thin‑walled trims and thick‑section structural parts.
Extremely Wide Adjustable Output
Flow rate from 100 to 2000 g/s covers small precision components (e.g., automotive interior details) and large‑scale integral moldings (e.g., building panels, boat hulls).
Accurate Metering & Proportioning
Closed‑loop ratio control keeps deviation ≤±0.3%, ensuring high finished‑product yield even with varying fiber‑reinforced formulations.
Multi‑Formula Storage & Quick Changeover
PLC stores multiple recipes; fast switching enables flexible production of different parts without lengthy setup, maximizing equipment utilization.
Robust Tank & Temperature Management
Optional 200L/300L tanks with independent temperature control and circulation stirring maintain stable material viscosity for consistent dosing.
Efficient Cleaning & Low Maintenance
High‑pressure circulation cleaning combined with air purging reduces downtime and extends service life of the mixing head and seals.
