Colour Coating Line Enters Production in Vietnam
The blue continuous colour coating line in Vietnam entered production in August 2019. Its maximum line speed is 120 m/min; actual operating speed depends on the product and process conditions.
At a glance
- The blue continuous colour coating line in Vietnam entered production in August 2019. Its maximum line speed is 120 m/min; actual operating speed depends on the product and process conditions.
- The line is a continuous colour coating line (CCL): decoiling, pre-treatment, coating, curing, cooling and continuous coiling.
- Delivered by PRC Technology as general contractor, with a single point of responsibility for the owner.
Stable coordination between production sections
The critical point of a coating line is the stable hand-over between pre-treatment, coating, curing and coiling, not the performance of a single coater. The line was configured to the product programme: the coating section assigns heads for primer, topcoat and backcoat; the curing and cooling sections are matched to the coating system in temperature, air volume and line speed; the entry and exit accumulators and the coiling tension determine whether the strip surface is disturbed during strip joining and coil changes.
Commissioning and operating conditions
Commissioning coordinates strip handling, pretreatment, coating, curing, cooling and coiling. The operating recipe is selected for the substrate and coating system; 120 m/min is the maximum line speed, not a constant speed for every product.
After start-up
Once in production, the focus shifts to batch stability: first-coil pass rate, colour-change and cleaning time, and the reproducibility and traceability of surface defects. The PRC Technology project team continues to follow operating data and supports performance acceptance and operator training.

Frequently asked
What type of line is this?
A continuous colour coating line (CCL) processes metal strip through pretreatment, coating, curing, cooling and recoiling. This blue line entered production in August 2019; its maximum line speed is 120 m/min.
What did PRC Technology do on this line?
PRC Technology delivered the line as general contractor: process and equipment concept, equipment design and supply, electrical and automation configuration, on-site installation and commissioning, and start-up support and operator training, with a single point of responsibility for the owner. The contractual scope prevails.
Which figures are tracked after start-up?
Batch stability: first-coil pass rate, colour-change and cleaning time, film-thickness uniformity, coating appearance and reproducibility of surface defects; performance figures follow the agreed acceptance documents.
