Custom Rotomolded Parts
Rotational molding is inherently suited to custom, low-to-medium volume production. Tooling costs are a fraction of injection molding, the process accommodates complex hollow geometries, and wall thickness adjustments can be made without building a new mold. Luban provides a complete OEM service: design consultation, CAD modeling support, in-house mold manufacturing, sampling, production, secondary operations, and export packaging.

- Agriculture — water tanks, chemical storage vessels, livestock feeders
- Marine — kayaks, buoys, dock floats, fuel tanks, pontoons
- Construction — traffic barriers, road cones, safety equipment
- Industrial — bulk containers, chemical drums, machine housings
- Medical — patient transport cases, sterile equipment containers
What the Tooling Decision Looks Like at Low Volume
Rotational molding earns its place when volumes are too low to justify injection tooling but the part is too large or too hollow to fabricate. Tooling costs a fraction of injection tooling, and because wall thickness is adjustable without building a new mold, a 3 mm part and an 18 mm part can come off the same tool — which is what makes an order of 50 units viable. Luban covers the whole chain from Dongguan: design consultation and CAD support, the mold itself, sampling, production, secondary operations, and export packing. So an agricultural tank, a marine buoy, a traffic barrier, a machine housing or a medical transport case is quoted as one job rather than as a tool quote plus a separate parts quote.
