HongFox manufactures PDCPD (polydicyclopentadiene) UAV fuselages, robot covers, yacht hulls & EV enclosures via low-pressure RIM molding. Density 1.03 g/cm³, HDT up to 110°C, batch from 50 pcs.
Low-pressure reaction injection molding — the sweet spot between performance and cost
<1 MPa cavity pressure. Aluminum or steel molds. Wall thickness 2–12 mm. Parts up to 2 m+ in a single shot. Cure time 30–180 seconds.
Unnotched impact 80 kJ/m². Ductile fracture — absorbs crash energy. Radio-transparent for GPS, 5G and telemetry signals. No signal shadowing.
Density 1.03 g/cm³ — ~40% weight reduction vs steel equivalents, lighter than aluminum with superior crash deformation tolerance.
Tooling cost 60–80% lower than injection molding. Viable from 50 to 5,000 pcs. No steel-tooling barrier for prototyping and niche production.
Four core application verticals, one manufacturing process
Fuselage, arm covers, gimbal housings, VTOL bodies. Span 250mm to 1800mm. RF-transparent, crash-tolerant, paint-ready Class-A surface.
Quadruped shells, sensor pods, joint housings. Custom textures, integrated mount points, EMI-shielded variants available.
Console shells, hatch covers, corrosion-resistant trim. UV-stable, foam-cored sandwich options, gel-coat-free finish.
