Custom Rotomolding Molds — Engineered In-House

A mold is where rotomolding success is won or lost. BENFAN runs its own mold-processing workshop: we design, cast, fabricate, repair and maintain molds, and keep a growing mold library so similar products can be quoted and tooled fast.

What we deliver

From a new mold built around your 3D file to repair of an existing one — full lifecycle support.

📐

New mold design

Optimize wall-thickness uniformity, demolding angle, parting line, insert fixation and venting to cut scrap and cycle time.

🥉

Cast aluminium

Cast-aluminium molds for fine surface and complex shapes — the workhorse for most rotomolded parts.

⚙️

Fabricated steel

Fabricated steel molds for large, heavy or high-volume tools with strict dimensional needs.

🔧

Repair & maintenance

Fast repair of worn or damaged molds and precision upkeep to keep them production-ready.

🗄️

Mold library

Years of molds covering common products — quick response for similar orders and lower re-tooling cost.

🔄

Mold management

Efficient storage, retrieval, pre-heating and maintenance flow to cut changeover time and lift utilization.

Mold capability for hard parts

We routinely handle the tough ones: large molds with complex internal structure, many inserts, multiple curved surfaces, ultra-high precision, double-layer / embedded / foaming processes. These are exactly the molds behind our UAV cases, water-rescue devices and floor-scrubber programs.
