Everything You Need to Know about ‘Coil Coating’ & Its Latest Applications

 In this age of technological advancement and manufacturing 2.0, EPCON has been continuously innovating and improving upon proven technologies to offer more sustainable industrial solutions to establish a cleaner future.

When it comes to the industrial applications, painting is considered to be one of the most expensive aspects other than raw materials and manufacturing. So what can these operations do to reduce the expense for finished products? The answer is ‘Coil Coating’.


 

What is Coil Coating? How does it work?

There is a famous slogan nowadays, “Finish first and fabricate later”. The coil coating process follows this motto and enables manufacturers to paint the metal sheet and coils before it is being used to manufacture other products. This simple process can help to reduce the production cost by decreasing the expenses for multiple paint jobs. It is not only an affordable option but one of the most sustainable options to be implemented across applications regardless of the industry.

In this particular painting process, the industrial rollers apply a thin layer of polyurethane that acts as a natural coating over the metal sheets. Usually white or colored, this process is applicable for bulk and huge coils of metal that help to save time, money, and effort as well. Packed with convenience and efficiency, this coating process can reduce an exponential amount of environmental damage.

Common Steps of Coil Coating Process

  • Unwinding the huge coils of metal sheets and cleaning (if needed)
  • A chemical pre-treatment process is applied either on one side or both sides of the sheet
  • Single or multiple layers of liquid paint and coating powder are applied before curing or laminating it with plastic films. Usually, polyurethane is common material widely used in this step
  • Curing and drying of the sheets to ensure proper bonding and durability of coatings
  • Winding and cooling of the same metal sheet through slitter, sheeter, or anything other fabricating equipment

Beneficial Aspects of Coil Coating Process

The Coil Coating process is gathering more attention across the globe due to its adaptability and universality. While every industry is looking for ways to integrate more sustainable options in business, coil coating is a proven solution. Here are some beneficial aspects of the process.

 

  • This coating process decreases onsite environmental hazards and damages and creates less pollution.
  • A cost effective solutions with financial appeal due to automation and mass production of coil-coated materials, running 24X7.
  • Time-saving and nearly error-free process that is applicable across a wide range of industries
  • Enhances durability and aesthetics of the metal sheets that can be directly fabricated

 

EPCON is experienced at designing integrated coil coating lines that combing prime, curing, and finishing ovens with air pollution control technology to create a more efficient operation.

Q1 2023: CEO Business Insider

Epcon has been fortunate to have several major projects, which have carried forward into 2023. And, we are sufficiently busy, with a backlog of 6+ months. While I tend to be an eternal optimist when it comes to the economy, and business outlook in general, there is a lot of grim news surrounding the financial sector due to inflation and the Federal Reserve raising interest rates. Now we have a new phenomenon to deal with – the banks.   The fault line or the weakness of the banking was totally predictable. I do not know how and why the financial experts and the bankers could not see the problems with the hundreds and billions of dollars for loans at near 0% interest rate, for the past few years, and now the cost of money lending is up to 5-7%. And the big banks will need to bail out these smaller and weaker banks, and the US government will have to bail out the bankers. This bank failure cannot be ignored nor slid under the rug. While global supply chains are gradually improving,

Business Outlook & CEO Insights

  Dear Friends, Happy New Year ! It is a great pleasure to welcome 2024 with great hope and aspirations of peace, a better economy, and a more stable world.  As we look forward to a strong 47 th year in business, let’s reflect back on the past 12 months. 2023 started as a continuation of 2022, where the high inflation caused havoc in the economy, creating uncertainties, polarized shortages, supply chain issues, skilled and unskilled labor shortages. All of this uncertainty had everyone fearfully bracing for a global recession.  “Soft-landing” or “hard-landing” was the ongoing subject of discussion, but the economy dodged a recession in 2023. In the end, the year closed with a decent GDP growth at 2.5%. Indications are showing, and economists are forecasting a slowdown in 2024. The expectation is that the GDP will be 1.7% and inflation will fall below 3%. Predictions are that inflation will fall to 2% by the end of Summer, with anticipated fluctuations until the year's end.
