Product Overview
Suitable for molding surfboards, small leisure boat hulls, water sports equipment and other products.
The RIM composite PU foaming machine is purpose-built for molding surfboards, small leisure boat hulls, and water sports equipment. It supports carbon fiber and corrosion-resistant fiber materials, enhancing waterproof, impact-resistant, and seawater corrosion-resistant properties. 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 and strengthens structural integrity. The stable, adjustable flow rate (30–300 g/s) enables integral molding of small and medium boat hulls with uniform quality. Flexible process settings support small-batch customization and multi-specification production, meeting the dual requirements of lightweight and structural strength. Applicable conformity documents are reviewed for the quoted equipment configuration.

Operation Workflow
Carbon/Fiberglass Reinforced Material Preparation
Prepare polyol and isocyanate at the target ratio (100:90-110); select carbon fiber or corrosion-resistant fiber materials per product requirements.
Tank Loading & Temperature Setting
Load polyol into Tank A and isocyanate into Tank B; the 1A1B system maintains 25-45°C with circulation stirring for consistent material quality.
High‑Pressure Homogeneous Mixing & Pouring
The PLC-controlled dosing system dispenses precisely; high-pressure mixing at 150-200 bar ensures uniform fiber dispersion, with pouring rate adjustable within 30-300 g/s for different hull sizes.
Mold Filling, Negative Pressure Venting & Curing
Inject composite into the mold; negative pressure venting removes trapped air, while high-pressure homogenization ensures complete fiber wet-out and a waterproof, corrosion-resistant hull.
