Things to Consider in a UV Powder Coating Line

Over the years paints are formulated to either cure at ambient temperature or at elevated temperatures. This depends on the paint formulation. Paints which are cured in convection oven normally take between 20-30 minutes and the same paints are cured within 3-4 minutes in IR ovens. When you use UV powder system along with UV powder it takes less than a minute. This reduces your energy consumption drastically in your powder coating line/plant. This becomes a game changer. UV powder is generally followed by IR gel zone .UV technology can be used on metal, plastics, wood MDF, composites etc. The finish achieved with UV powder with far more superior compared to traditional powder coating. UV lighting technology together with the right paint formulation could offer the potential to expand to to other industries.The industries that can benefit using UV powder coating technology include automotive components, all types of steel furniture, utility vehicles, aerospace, industrial products, healthcare and many more. Prism surface coatings is a turnkey system supplier of complete UV powder coating line and systems. Prism can also supply you the UV powder.

What is UV Powder coating and its Advantages?

UV cured powder coatings are an industrial finishing technology giving a resilient and durable finish to a variety of materials and products. UV cured powder coatings are available in many colors, glosses and textures and formulated to meet specific performance requirements. UV powder coatings are produced in the same manner using the same equipment as thermoset
powder coatings – blended, extruded, chilled, chipped, milled, classified, sieved, and packaged. Prism is the turnkey supplier of complete UV powder coating plant and we also help you supply with the powder.

Advantages of UV Powder Coatings:

1.Environmentally Friendly
UV powder coatings contain no volatile organic compounds (VOCs), or hazardous air pollutants (HAPs), are solvent free, and non-toxic. They contain no chemicals or compounds that can damage the environment and waste materials can be recycled.

2· Efficient Process/Speed of Curing
UV curable powder coatings cure faster and use less energy than other finishing processes. More parts are finished in less time.

3.Ability to Coat Heat Sensitive Materials
UV cured powder coatings melt at lower temperatures and cure faster than other coatings. This advantage makes it possible to powder coat “heat sensitive” materials like wood, medium density fiber board (MDF), plastics, composites, and carbon fiber without damaging the substrate.

4. Small Plant Footprint
A UV powder application system uses less plant floor than other paint systems. Footprint could beas small as 185 square meters, potentially less depending on type of product finished and system design.

5. Ease of Material Handling
UV powder is safe to use and is easily recycled. Use of UV curable powder coatings does not require any permits, special air handling, operator breathing devices, or flammability restrictions. Faster and Greater Return on Investment
A UV cured powder system can finish more material in a given period of time. The benefits of a fast system are an increased operating capacity, reduced work in process inventory, lower cost of quality, less energy usage, and increased profits per hour – generating a faster and greater ROI.

 

Symptoms Of A Bad Paint/Powder Drying Oven

How to know if your paint or powder curing oven is giving you issues? The paint curing oven is one of the most important part of your painting line and a bad curing oven can lead to a lot of risk and decreased productivity. Your curing oven should be able to satisfy all cure  parameters and perform consistently.

Some of the side effects or symptoms of  poorly designed paint curing oven are heat loss, chipping, poor airflow, orange peel, poor adhesion, difference in gloss, uneven colors/shade mismatching, poor chemical resistance, poor corrosion resistance etc. To avoid all these issues the paint curing oven must be designed properly with proper air flow and efficient heat exchangers (indirect heating). Prism ovens are well designed and known for their temperature accuracy. This is achieved through an effective air seal between the oven and the outside ambient conditions. Prism can supply various types of paint or powder curing ovens which include A Zone ovens, camel back ovens, ground mounted ovens and also IR ovens.

 

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.
