HIGH QUALITY PLASTIC PAINTING PLANT FOR AUTOMOTIVE TRIM PARTS

To achieve full compliance with the project specifications at the required capacity and to secure a future flexible plastic painting line, the Electron installation was supplied with all the necessary process zones: Load/off-load, cleaning, deionizing, spray booths and flash-off for primer, base coat and top coat, curing oven and cooling zone.

Steven Schofield, Managing Director at Electron Technical Solutions Ltd., about the project and plant delivery:

“I want to forward a few words about Electron’s high regard for the Moldow team. We had a very tight timeline to meet, but Moldow approached our project in a professional manner the like of which I have never encountered before. This to me was exceptional, and when I tell the story of Electron’s plant journey to visitors, it is greeted with semi disbelief. Not only did Moldow deliver on time but the support we have had since handover has been unbelievable and the enthusiasm to resolve our issues has been exemplary”.

Painting Plant for Plastic Trim Parts – minimized process contamination

The Electron line is designed to minimize contamination between the individual zones to achieve the necessary high-end product quality. The minimum contamination between the process zones is ensured by a designed and accurately controlled down-draft ventilation system, including individual control of extraction and inlet airflows.

The conditioned and pre-filtered inlet air is provided through an integrated filter ceiling to achieve the best possible working conditions for the operators and optimum air distribution for the process air replacement.

The Electron design further includes air curtains at all conveyor silhouettes between the individual process zones. The air curtains and ventilation keep dust contamination at a minimum by efficiently separating the process zones and reducing the air leakage.

To ensure that the objects are clean and suitable for high quality painting, the objects will enter the process cleaning area after being initially cleaned in the loading zone. The process cleaning zone is efficiently ventilated to allow for a dust-free environment with minimum surface contamination.

After the manual cleaning the objects enter the deionizing zone. By exposing the plastic parts to a deionized air flow together with ventilating the area around the objects, any fine surface dust settlement is removed before the painting process.

The spray booths are separated by closed neutral zones and followed by individual flash-off areas where the solvents are evaporated by the integrated down-draft ventilation system.

After the final top coat spray booth and flash-off, the objects enter the curing oven where the painted surface is cured in a gas fired convection oven. More than 40 years of experience allow Moldow to carefully design highly reliable curing ovens which provide optimum temperature accuracy.
