Manufacturing Capabilities

Cutting, surface treatment, coating, assembly and load testing under one roof — every set load tested and parallel tested before it is released.

Facility

One roof, one continuous flow

Our factory is organised as a single continuous flow: incoming inspection of engines and alternators, sub-assembly of base frames and fuel tanks, main assembly, electrical wiring, then load testing before the set enters the paint booth. Nothing is painted or packed until it has passed full-load testing.

Capacity is deliberately flexible rather than single-brand. Because we build around sixteen engine platforms, the same line can deliver a 10 kVA Kubota silent set on Monday and a 4,000 kVA containerised package the following week.

  • Main assembly line for open, silent and containerised packages
  • Load-bank test bays — four-point test at 25 / 50 / 75 / 100 %
  • Parallel testing for multi-set installations
  • In-house powder-coat and painting line
  • Acoustic lining cut and fitted in-house
  • Export packing with a complete documentation set

Four Core Processes

Cutting, surface treatment, coating, assembly and test

01

Laser cutting and bending

Every enclosure and base frame is cut and formed precisely, which improves weather sealing and the overall finish. Acoustic lining is machine-cut for a smooth surface and efficient noise reduction.

02

Pickling, phosphating and blasting

Enclosures are pickled and phosphated and base frames are blast-cleaned, leaving a smooth metal surface and strong powder-coat adhesion that resists flaking.

03

Powder coating and painting

High-quality powder coating and custom colour painting hold their colour. High-corrosion systems are available for coastal and other harsh environments.

04

Assembly and testing

Experienced assembly to Cunmi build standards. Every generator set is load tested and parallel tested before it is released for delivery.
