Things to Consider In An Extrusion Powder Coating Line

Installing a horizontal automatic powder coating plant/line can have its own set of challenges from an extruder point of view. As you know such investments should give your company a quick ROI and at the same time enhance your brand image. The plant should perform consistently satisfying all your demanding customers at-least for the next 20 years. Hence it is advisable to install a line with high quality standards with a professional design.

Many extrusion companies worldwide have made the mistakes in the past while choosing the wrong capacity and design of the plant looking at only plant manufacturers country of origin. But the architects and builders always demand quick deliveries, more colors, international quality standards etc. By spending marginally a higher price if you can have a plant with higher coating capacity, it will help you to drastically bring down the ROI period. We have all the calculations relevant for aluminium profile coating industry to support this claim.

Hence we strongly recommend you to focus on choosing the right type of plant design and coating capacity to bring down ROI period. Prism has installed numerous aluminium extrusion automatic powder coating lines around the world for many European and middle east companies around the world.

Why Distribution Transformers Must be Powder coated And Not Painted?

Many distribution transformers up-to 220 kVA are designed to have fins all over the tank. These fins have upto 440 mm depth and have around 50 mm gap between them.It is difficult to find a spray painting gun that can penetrate the paints between the fins and deposit effectively protecting it against corrosion.These transformers are mounted on top of a post /poll and are subject to hot, humid, rainy and harsh weather conditions through out the year. The chances of repainting are very less hence the quality of coating should be able to withstand these conditions.

The conventional practice is to have a 3 coat paint system with manual shower coating as the primer coat followed by intermediate and top coat using spray painting. This 3 coat system is an efficient process wasting a lot of paint, not environmental friendly and does not cover all the surfaces between the fins.Hence in order to obtain C4 or C5 quality standards Prism has introduced a special technology where you can powder coat the distribution transformers, tanks, lids and conservators.When you powder coat the transformers you reduce on your running costs as you can reuse the powder rather than disposing it. With powder coating you also get better protection compared to painting especially when it is exposed to harsh weather conditions.
