Configured around your process

We start from the workpiece and the takt time, not from a catalogue. Every unit is sized, simulated and validated before shipment.

01

Process-first sizing

Machine width, lamp power and conveyor speed are derived from part geometry and required line rate.

02

Thermal simulation

Airflow and temperature fields are modelled before fabrication to avoid hot spots and uneven cure.

03

Line integration

Mechanical, electrical and signal interfaces are matched to your existing conveyor or robot cell.

04

Validation & handover

Factory acceptance runs with your samples, documented parameters and on-site commissioning.

05

Consumables & spares

Lamps, nozzles, belts and filters are kept in stock for the lifetime of the machine.

06

Documentation

Electrical drawings, spare-part lists and maintenance schedules delivered in your language.

Curing width 100 – 1600 mm
Temp. uniformity ± 1 °C
Line speed 0.5 – 20 m/min
