Since 2009 we have designed, built and commissioned rotational moulding machines, CNC aluminium moulds and complete auxiliary lines for plastic tank, cooler box, kayak, playground and automotive part producers in more than 40 countries.
Our engineering team of 40+ specialists — 80% degree-qualified, each with over ten years of hands-on rotomoulding experience — works from a 20-acre manufacturing base. Every machine is built around measured process data: oven air balance, arm rotation ratio, internal air temperature (IAT) curve and demoulding ergonomics, so your cycle time and scrap rate are predictable before the first production run.
From single-arm rock & roll units for kayak builders to four-arm carousel lines for high-volume tank plants — every configuration is matched to your part size, wall thickness and daily output target.
Independent-arm turret design where loading, heating and cooling run in parallel — the standard choice for continuous tank and bin production.
Straight-line shuttle with one oven and two working stations — a compact, lower-investment entry into stable industrial rotomoulding.
Multiple shuttle arms share one high-efficiency oven, giving carousel-level throughput with the flexibility of independent recipes.
Square-frame carriage built for tall or heavy moulds where mould weight distribution and even air circulation are critical.
Enclosed hot-air oven with rocking main axis — the accurate route for long tanks, kayaks and slender agricultural parts.
Direct-flame heating for the fastest start-up and the lowest capital cost per litre of tank capacity, popular with workshop-scale producers.
A documented eight-stage workflow keeps engineering, tooling and commissioning aligned — so the machine that arrives at your plant matches the drawing you approved.
Part drawing, resin type, wall thickness, target output and plant utilities are reviewed to define the machine class.
We issue a 2D plant layout, cycle-time estimate and gas/electricity consumption forecast for your approval.
3D mould design with shrinkage compensation, venting, inserts, parting line and texture confirmed in writing.
Frame welding, stress relief, CNC machining, burner and PLC assembly under in-process inspection records.
Machines run with your mould in our plant; temperature curves and first-article parts are recorded on video.
Anti-rust treatment, sea-worthy crating, full packing list and HS documentation for smooth customs clearance.
On-site erection, gas/electrical connection, commissioning and operator plus maintenance training.
Remote diagnosis, PLC parameter backup, two-year recommended spare list and mould refurbishment service.
