Oven Refurbishment - Keep Your Industrial Oven Running Like New

As we are all aware, a properly functioning oven is critical to the successful application of DuPont™ Teflon® industrial coatings. Regular preventative maintenance is an important step in this process.  But what if your oven needs more than just calibration or a few new parts?  Precision Quincy can help you regardless of the oven brand.  The case study below highlights a recent success story where Precision Quincy refurbished a 40-year-old outdated oven back to new condition. 

During a recent preventative maintenance visit with a large OEM, Precision Quincy’s Service Technician discovered the oven had an extreme amount of byproduct buildup on every moving component, which also clogged the burner itself.  Replacing the oven would have been a huge unexpected expense causing a 2-3 week shut accruing addition expenses in operational downtime.

Precision Quincy suggested oven refurbishment as an alternative to purchasing a new oven. All moving components were replaced, as well as the outdated and defective burner controls.  It only took 4 days to rebuild the oven onsite, eliminating the 2-3 weeks of operational downtime involved in purchasing a new oven.  Precision Quincy was able to save the OEM over 7 times the cost of the rebuild, including operational downtime and new oven purchase price, by choosing oven refurbishment. The refurbished industrial oven now operates like new just as it did the day it arrived, 40 years ago.

There are several powder coating series offered through TruPak, but there are also some series that are not part of this program. These products are available in larger sizes by calling Ken Barnes at 302-602-8731. This article focuses on the 3000 High Temperature Systems.


TCI's 3000 Series High Temperature Systems is an extensive line of thermoset powder coatings for high temperature applications. The 100, 200, 300 series offer varying degrees of temperature resistance. These products can be formulated in a wide range of colors, gloss, and surface finishes.  

100 Series:
Used for many applications where parts will be subject to moderate temperature ranges, typically in the range of 400F – 650F. Applications include exterior of ovens, underhood car components, and lighting applications.

200 Series:
Ideal for higher temps applications that can subjected to temperatures up to 800F. Applications include BBQ grills, stoves, and engine parts.

300 Series:
For extreme high temperature applications that can withstand upwards of over 1100F. Although you may see a slight change in color and gloss, this product line holds tight to the surface for ultimate protection. Applications include mufflers and engine components.

Properties of Teflon: Unique Electrical Properties

DuPont Teflon® industrial coatings are highly durable and long lasting performance coatings that have a distinct application process and qualities that offer solutions in a variety of industrial markets.   This series of blogs will highlight one of these inherent properties of Teflon®  coatings and how these properties can solve a variety of problems. 

Unique Electrical Properties: Over a wide range of frequencies, DuPont™ Teflon® industrial coatings have a high dielectric strength, low dissipation factor, and high surface resistivity.  Dielectric strength is the highest voltage that the coating can withstand before it breaks down. The low dissipation factor means that the absorbed energy dissipated as heat is low. PFA and ETFE have the highest dielectric strength at almost 2,000 volts per mil. However, in order to achieve these results, the coatings must be completely pinhole-free, so multiple coats are usually recommended.

Tony's Recipe of the Month: Spaghetti alla Checca

Tony Abato, our VP of Sales here at Intech Services, and an amazing Italian chef, will be sharing one of his delicious recipes every month. Trust us, you don't want to miss out on what Tony's cooking! 

Spaghetti alla Checca


Ingredients:
5 or 6 Italian Roma tomatoes - fresh
Garlic - minced
Basil - fresh, chopped
Parmegiano e reggiano - grated
Cracked black pepper
Salt
Extra virgin olive oil


Preparation: 
You need a pot of boiling water and a bowl of cold water with ice in it. Cut a little "X" into the skin at the bottom end of each tomato. Put the tomatoes one at a time in boiling water for thirty seconds to a minute. It should be just long enough to see the skin begin to split. Remove with a slotted spoon and throw in the cold water for a minute. To separate the skin from the tomatoes, cut the hard stem end off and squeeze. The whole tomato should slip out of the skin easily.

Cut off the hard, often discolored, stem end of each tomato and discard. Cut the tomato in half length-wise, scrape the core off the insides, and discard. Take the tomato halves, cut in strips lengthwise, and dice in 1/4 inch pieces. 

Combine the tomatoes and the rest of the ingredients (minced garlic, chopped fresh basil, grated parmegiano e reggiano, cracked black pepper, salt, and extra virgin olive oil). Let it marinate for half a day in a colander sitting on a plate. When ready to serve, roll hot, lightly-buttered spaghetti into the sauce. Add a little extra cheese at the table.



Keep checking the blog to see Tony's Recipe of the Month.  Did you try this recipe?  Let us know what you thought of it or if you have questions for the chef, post them below!

Powder Coating Application: Pretreatment

Pretreating a substrate for powder coating is an important step in the application process. Powder coating a substrate with contaminants on the surface will result in poor performance of the coating. Here is an overview of the pretreatment step for powder coatings:

1. Clean the substrate to remove all contaminants, including soils, oils, oxides, and smut. Titration readings measure the total alkalinity or acidity levels. Even if the titration readings are fine, watch out for sludge or soil buildup in tanks that because it will reduce the cleaning activity.

2. Rinse the substrate to remove any remaining contaminated solutions from the surface. It also adjusts the pH for the next step.

Conversion coatings are a film which changes the physical and chemical nature of the metal surface. A clean surface is required for the reaction. You might need conversion coatings for your application.

Common types of conversion coatings:
  • Iron phosphate for ferrous metals
  • Zinc phosphate for ferrous metals
  • Chromate conversion for aluminum
  • Manganese phosphate

For more information about pretreating for powder coatings, read TCI's Troubleshooting Guide.

Intech Services and TCI Powder Coatings have partnered to create TruPak, a program that offers over 300 of TCI's most popular powder coatings in 1, 3, 5, and 10 pound boxes. Click here to buy TruPak powder coatings.

Teflon Technical FAQ: Rough Texture


Every day at Intech we receive requests for technical help with DuPont Teflon® industrial coatings.  If you have a technical question, please feel free to call and speak to one of our technical sales representatives.  Once a month, we post a frequently asked question here on our blog. 

Question: My part appears to have a rough texture. What causes this?


Answer: The DuPont™ Teflon® industrial coating should be smooth and have a soft touch to it. This usually happens when the part is under-baked. Use a thermocouple to make sure the part temperature is correct. When the fact sheet refers to the cure time, it is talking about the temperature of the part's substrate NOT the oven temperature. Another issue that could cause under-baking, is your oven is not calibrated properly. 

If you need more help, call us at 302-366-8530.
