Custom Rotomolding — OEM / ODM

Turn your design into a manufacturable hollow part. We handle integrated tooling, material selection and production, with engineering review at every step.

Start a project

From drawing to delivery

1

Define requirements

Function, size, quantity, exposure, destination and acceptance criteria.

2

Review design & material

We assess manufacturability, wall map, material grade and tolerances.

3

Develop tooling & sample

In-house mold making, sample run and validation tests.

4

Approve acceptance

Agree critical dimensions, minimum walls, sealing and reports.

5

Produce, inspect & ship

Batch production with records, inspection and export packaging.

Why custom rotomolding

Large, hollow, seamless parts at low tooling cost — ideal for housings, tanks and protective cases.

Rotomolding excels at complex, large hollow forms with uniform wall thickness and minimal seams. It suits low-to-mid volume production where injection or blow molding would be costly or impractical.
