Product Overview
Suitable for molding surfboards, small leisure boat hulls, water sports equipment and other products.
This RIM composite PU machine is purpose‑built for molding surfboards, small leisure boat hulls, and water sports equipment. The system supports carbon fiber and corrosion‑resistant fiber materials, significantly enhancing the waterproof, impact‑resistant, and seawater corrosion‑resistant properties of finished products. The 1A1B two‑component system with independent temperature control and circulation stirring ensures consistent material quality. High‑pressure homogeneous mixing at 150–200 bar minimizes material delamination while strengthening overall structural integrity. The stable and adjustable flow rate (50–500 g/s) enables integral molding of small and medium‑sized boat hulls with uniform quality. Flexible process parameter settings support small‑batch customization and multi‑specification production, meeting the dual requirements of lightweight construction and structural strength for water sports equipment. The machine holds CE and ISO9001 certifications.
Operation Workflow
Carbon/Fiberglass Reinforced Material Preparation
Prepare polyether polyol and isocyanate according to the target mix ratio (100:90–110). Select carbon fiber or corrosion‑resistant fiber materials for the specific product requirements.
Tank Loading & Temperature Setting
Load polyol into Tank A and isocyanate into Tank B. The 1A1B independent temperature control system maintains 25–45°C with circulation stirring for optimal material consistency.
High‑Pressure Homogeneous Mixing & Pouring
The PLC‑controlled dosing system (accuracy ≤±0.3% full dynamic range) dispenses materials precisely. High‑pressure mixing at 150–200 bar ensures uniform fiber dispersion. The pouring rate is adjustable within 50–500 g/s for different hull sizes.
Mold Filling, Negative Pressure Venting & Curing
Inject the composite material into the mold. The mold negative pressure venting system removes trapped air. High‑pressure homogenization ensures complete fiber wet‑out. The finished hull features waterproof, impact‑resistant, and seawater corrosion‑resistant properties.
