Product Overview
Specially designed for RRIM (Reinforced Reaction Injection Moulding) process, widely used in automotive structural parts, agricultural machinery heavy-duty parts, large engineering structural parts, high-end marine accessories and other fields.
This RRIM PU molding machine is purpose-built for the reinforced reaction injection molding process, delivering superior strength and toughness for demanding applications. The system supports carbon fiber, glass fiber and various high-strength fiber reinforced polyurethane materials, meeting the core requirements of high strength, high toughness, impact resistance and wear resistance. The professional RRIM process features high-pressure homogeneous mixing with uniform fiber dispersion, producing products with strength and toughness far exceeding ordinary RIM products, suitable for heavy-duty and impact-resistant scenarios. Accurate two-component metering and proportioning with error ≤±0.3% ensures no delamination or defects in finished products, with strong molding stability that greatly improves yield rate. The adjustable large-flow output supports both integral molding of large structural parts and pouring of small precision reinforced parts. The intelligent multi-formula storage and switching system adapts to different fiber reinforced raw material ratios with simple operation, meeting the needs of multi-category flexible production. The machine is suitable for mass production and customized processing across various industries.
Operation Workflow
Fiber-Reinforced Raw Material Preparation
Prepare polyether polyol and isocyanate according to the target mix ratio (100:90~110). Select appropriate reinforcing fibers (carbon fiber, fiberglass, or other high-strength fibers) and ensure proper pre-conditioning for optimal dispersion.
Tank Loading & Temperature/Pressure Setting
Load polyol into Tank A and isocyanate into Tank B. The 1A1B independent temperature control system maintains 25–45°C with circulation stirring. Set mixing pressure to 150–200 bar for high-pressure homogenization.
High-Pressure Homogeneous Mixing & Fiber Dispersion
The PLC-controlled dosing system (accuracy ≤±0.3% full dynamic range) dispenses materials precisely. High-pressure mixing ensures uniform fiber dispersion throughout the composite, delivering product strength and toughness far exceeding ordinary RIM products.
Mold Filling & Negative Pressure Venting
Inject the reinforced composite material into the mold. The mold negative pressure venting system removes trapped air, while high-pressure enhanced homogenization ensures complete fiber wet-out and void-free molding. The pouring rate is adjustable within 100–2000 g/s for different part sizes.
