Gemstar manufactures custom rotationally molded plastic parts for OEM programs spanning UAS/UAV, agriculture, heavy machinery, construction, and material handling. Components can range from fuel tanks to dashboards, with each part developed around the required geometry, durability, and production demands. For UAS/UAV manufacturers, Gemstar develops custom lightweight, durable fuel tanks designed to meet the specific space, weight, and operational requirements of drone platforms. Gemstar combines engineering support with in-house tooling and ongoing tool maintenance, helping manufacturers move efficiently from part development into repeatable production while maintaining consistency across successive orders.
Rotational molding uses powdered resin inside a closed tool that is heated while rotating across multiple axes, allowing molten material to distribute around the mold interior before cooling. The process supports hollow, intricate forms without internal forming pressure, helping produce impact-resistant parts without pressure-related stresses, welded seams, or separate joints. For suitable OEM components, this single-piece approach can reduce assembly requirements, lower weight compared with fabricated metal designs, and provide lower tooling investment than injection molding at mid-volume quantities.
