Our Product Lines
Four core categories manufactured entirely in-house by a China-based rotomold mold manufacturer.
As a rotomold mold manufacturer in China, Luban ships across the full product range below to buyers in the USA, UK, Spain, Italy, and 30+ other markets — sea, air, or express courier from Dongguan. Tooling, PU foam work, and finished parts all come off the same floor, so an OEM mold for rotomolding and the parts it produces ship from one supplier.
Manufacturing Capability
Every OEM mold for rotomolding we cut runs inside one envelope: one tool room, one production floor, one quality system — the figures below hold across all four product lines. Category pages carry the detail; this is the envelope we work inside.
Size, tolerance, and lead time all move with geometry. Send a drawing, a sample, or just a description and we will confirm against your actual part.
How a Part Gets Made
Four stages, all under one roof in Dongguan — no third-party toolmakers between your drawing and your shipment.
Design & CAD
We work from your drawing, a physical sample, or a description. Our engineers model the part, flag draft angles and wall-thickness risks before any metal is cut, and return a CAD file for your approval.
Mold Manufacturing
Molds are machined on our own 3-axis and 5-axis CNC equipment. Machined parting lines mean far less flash than hand-finished tooling, which keeps post-processing cost down and batch-to-batch consistency up.
Sampling & Approval
First articles are run on our production line and dimensionally inspected. You approve a physical sample — not a render — before we open a production run.
Production & Finishing
Trimming, drilling, welding, foam filling, insert installation, and assembly happen in-house, so parts leave finished rather than needing a second supplier.
Tooling and Parts From the Same Floor
Buyers looking for an OEM mold for rotomolding usually have to split the job in two — one supplier cuts the tool, another runs the parts. At Luban both stages sit in the same building in Dongguan. The CAD model, the CNC-machined mold, the first sample and the production run all move through one tool room and one production line, which is why wall thickness can be moved anywhere in the 3–18 mm range without cutting a new tool.
That is the practical meaning of working with a rotomold mold manufacturer in China rather than with a tooling shop alone: cast aluminum, machined billet aluminum and mild steel tools cut on 3-axis and 5-axis CNC; LLDPE, HDPE, cross-linked PE, PVC and nylon on the production side; parts up to 3,000 mm in any single dimension and from 0.5 kg to 250 kg. The four product lines above are variations inside that one envelope, not four separate supply chains.
Finishing work stays in-house for the same reason. Double-wall cooler shells are foamed with injected polyurethane on our own line, and trimming, drilling, welding, insert installation and assembly happen before parts are packed for export. Every mold and every production batch leaves with a dimensional inspection report under our ISO 9001 system, so the tool you approve is the tool your parts are measured against.
