Lean MDF Powder Coating – Case Study

Lean MDF Powder Coating Oven

Happy Customers!

If there are still sceptics out there about Lean Manufacturing, the please read this Lean MDF Powder Coating Case Study!
Some time ago we were contacted by Bells Powder Coating in Massachusetts. They had just gone through a Lean Manufacturing Program, and the savings allowed them to invest and expand. They chose to move into powder coating MDF, and bought a specialist Gas Catalytic Infrared oven from Vulcan Catalytic Systems (now Heraeus Vulcan). Here are a few of the Before and After comment from Bells Powder Coating:


  • “Half a million $ in lost revenue”
  • “Another half million $ in work going offshore”
  • “We needed to get a handle on costs right away”
  • “Competition was intense”
  • “We wanted to move into hot new markets, like powder coated medium density fiberboard (MDF)”
  • “Return on investment was too long”
  • “At about $98,000 per year, our natural gas bill was a huge expense”


  • “Increased productivity by 7%”
  • “Reduced costs by $70,000”
  • “Winning business back from China”
  • “Able to take a second look at launching the MDF product line”
  • “The Vulcan Catalytic (now Heraeus Vulcan) oven alone saved us $27,000 per year”
  • “15 companies interested in our powder coated MDF, through word of mouth alone”
  • “I haven’t even begun to advertise yet!”

Lean MDF Powder Coating

The added benefits of the MDF Powder Coating oven from Heraeus Vulcan, which is perfect for use in a Lean Manufacturing environment, means the benefits are multiplied, as they can make best use of the Lean advantages that an oven from Heraeus Vulcan can offer.

Wait till we tell them about the advances in single coat technology for MDF.

But I suspect they already know!

Heraeus Vulcan Leads the way

Heraeus Vulcan are the undisputed experts in MDF powder coating, having built the two largest, high production ovens in the world. Recent full production trials in Slovakia, ran faultlessly, with 0% defects. The trial only came to a halt when part production could not keep up with the powder coating line, and they ran out of parts to powder coat!

Doughty Engineering Ltd. – Flexible Powder Coating System – Case Study

Doughty_Logo - cmyk

New Powder Coating System Improves Response Time

Doughty Engineering is the world leader in the design and manufacture of rigging, suspension and lifting equipment for the film, TV and theatre industry. Prior to installing a new powder coating system, the company outsourced all their powder coating to two subcontractors. Whilst they were generally happy with service that was offered; typical turnaround time was anything from 2 days to a week. However, it became  clear to Doughty Engineering that over the last 5 years,  customers were becoming more demanding. They were holding less stock and so expected suppliers to hold large stocks and offer short lead times. Maintaining large stocks was not the answer, especially when there are 100’s of products. However, the converse was not an option either. If a customer called for a part and it was not in stock, they would simply phone up another supplier. This created the risk of losing hard won business to competitors.


So the ability to become much more flexible and responsive became important. The answer was to bring 95% of their powder coating “in-house”. Working with systems house Junair (Spraybooths) Ltd,  Gema UK and Caldan conveyors, the optimum system was designed and implemented. For the oven, Heraeus Vulcan Gas Catalytic IR technology was chosen due to its superior energy efficiency, small footprint, and improved finish quality over conventional convection technology.

Powder Coating System

What Happened Next?

The system has now been running faultlessly since February 2014. Key improvements  are:

  • 10% operating cost saving
  • Increased throughput
  • Considerably reduced  lead times
  • Three hours not unusual
  • Rush jobs in custom colours carried out “While You Wait”
  • Improved quality
  • Increased capacity
  • Customer retention maintained
  • Production easier to manage

Stephen Wright a Director of Doughty Engineering Ltd. said:

“Apart from the reduction in operating costs and the improvement in quality; the intangible benefits such as improved customer service and the ability to be more responsive will help us maintain existing and gain new customers. The new powder coating system has surpassed our expectations and made an immediate difference to our business”

MDF Powder Coating – Single Coat Technology Advances

The technology for MDF Powder Coating has been around for quite some time now. A number of companies around the world have been successful in creating MDF powder coating lines that can produce a quality finish and ensure repeat-ability. Heraeus Vulcan has been the leader in creating the oven curing technology in this field and has at least 6 large capacity oven systems installed worldwide. Such MDF powder coating systems require a primer and top coat. The aim of the primer being to seal the cut edges to create an edge that does not crack or split during the curing process. This problem has been exacerbated by variations in the quality of MDF used and its moisture content.  MDF Powder Coating Case Studies

MDF Powder Coating samples

MDF Powder Coating samples

What perhaps is little known is the nature of the finish that is being produced. Generally, the finish is textured to a lesser or greater degree.  This finish is generally very good, and can be used on a wide range of products, however,  when placed in a high humidity atmosphere, the problem of edge cracking becomes all too real.
Although MDF powder coating using textured finishes has its uses, it has not able to compete with a product that has been liquid coated. Such products have can have a uniform smooth finish, with varying levels of gloss. However, the disadvantages of liquid coating over powder relate to environmental, production cost and performance which can be summarized as follows:

  • A powder coated finish is significantly tougher than a liquid finish.
  • Over spray losses for liquid finishes can be as much as 75%.
  • Around 80% of liquid finishes used in the USA are solvent based and present environmental issues.
  • Even aqueous based finishes still contain some solvents contained within the resin structure
  • The storage and transportation of liquid finishes requires the use of IBC’s (Intermediate Bulk Containers). These require special handling and storage techniques.
  • In order to create a smooth finish, cut edges require one or two primer coats, smooth surfaces require at least one primer coat, before the final top coat is applied.
  • The extra part handling operations that are involved during the finishing process simply add cost to the finished part.
  • Liquid finishes still suffer from the problem of edge cracking in a high humidity atmosphere which makes them unsuitable for bathroom furniture.

One Coat MDF Powder Coating  – Heraeus Vulcan Leads the Way

The ‘holy grail’ in MDF powder coating and finishing is for a single coat, low temperature cure, smooth powder finish system, which will pass the any high humidity industry standard test irrespective of the quality and moisture content of the MDF substrate. Heraeus Vulcan have been instrumental in developing such a production system and high humidity testing thus far has proven to be outstanding. The end result is a system which  will open new market possibilities and enables those involved in MDF Powder coating  to  significantly reduce  production costs:

  • Over spray losses significantly reduced and waste powder can be collected and recycled.
  • Powder can be easily and more cheaply transported and handled in boxes.
  • Storage conditions less critical.
  • Easier handling on shop floor.
  • One coat system means part handling and labor costs can be reduced by up to 75%.

Industrial Food Drying Ovens

Industrial Food Drying Ovens – Gas Catalytic Infrared v. Convection Technology

If a new or replacement industrial food drying ovens are being considered, then a close look at the available technologies is advised. The two most popular available are Gas Catalytic Infrared ovens and conventional convection ovens. There are significant differences that relate to speed, suitability and cost. One of the key advantages of Gas Catalytic Infrared energy is that when applied to organic substances such as water , it is readily absorbed. This means that it is the water that is heated up and thus evaporates very quickly. This is achieved with very low levels of air movement across the food being dried. The added advantage is that the greater the moisture content, the greater the proportion of infrared that is absorbed. This means that the whole drying process can much quicker.

industrial food drying ovens _1

Sweet Potato Chips Being Dried in a Heraeus Vulcan Gas Catalytic Infrared Oven

The best method of applying the infrared heat is to pass the food to be dried on a flat bed conveyor system with some form of tumbling or vibrating bed to rotate the food , with the gas catalytic infrared panels placed in a shallow inverted ‘V’, above the conveyor. The length of the oven is determined by the required conveyor line speed, which in turn is determined by the required production output.

Added Control with a Gas Catalytic Infrared Oven

Because catalytic heaters can be arranged into zones, that allow precision control using a PLC system, one can have infinite control over the heat output of each zone, from 20% to full output. Heat profile recipes can be created and stored within the PLC control memory. In practice, this means that different recipes can be called up, to suit either different food substances to be dried, or, similar foods that have different moisture content from batch to batch.

What About Operating Costs?

industrial food drying ovens 2

A Flat Bed Industrial Food Drying Oven

In general Gas Catalytic Infrared, because it is much more efficient at converting the available energy in the gas to usable heat energy, is much less expensive to operate. Achieving the desired moisture content can take up to 80% less time than in a convection oven. Given that infrared ovens are inherently more efficient, then considerable savings can be expected. If the oven is a replacement for an electric oven then given the fact that Electrical Energy is around  four times as expensive as gas, then the savings become even more impressive.

Types of Food That Can Be Dried With a Gas Catalytic Industrial Food Drying Oven

Heraeus Vulcan’s gas catalytic infrared technology can safely be used on a wide range of foods and ingredients including grains, pulses and vegetables. Due to the nature of gas catalytic  reaction, there are no noxious gases produced to taint the food as only water and carbon dioxide is produced. Operators also report that yields and the quality of the dried foods are improved due to the highly consistent application of heat and the level of control available.

Finally, What about Bugs?

As insects, larvae and eggs have a high water content, they are heated up and killed off very quickly once they reach 60°C. This happens very quickly in the drying process, and means that pesticide use can be reduced or eliminated.

Energy Efficient Powder Coating System – Case Study

Working with our distributor in the Czech Republic, Surfin s.r.o, Heraeus Vulcan designed a new energy efficient powder coating system for Dikrt spol. s r.o. . The system is designed to cure powder on large agricultural parts, and the performance of the oven has exceeded expectation. Mr Weikert, the company’s owner stated:

“It used to take 70 minutes to cure our parts with the old convection oven. With the new Vulcan oven, it now takes only 12 minutes! We are very satisfied with its performance!”

How Did We Do It?

Working with our distributor in the Czech Republic, Jaroslav Blazek of Surfin s.r.o., the customer was able to see an existing Heraeus Vulcan system at another location and carry out part testing. Heraeus Vulcan then designed the powder coating oven to meet the customer’s requirements using SolidWorks. Heraeus Vulcan then provided Surfin s.r.o with a package that included the sheet metal design, the Heraeus Vulcan infrared heaters and the controls. To see a video on how Heraeus Vulcan designs and builds ovens, please follow the link.
The system was then easily constructed at the Surfin factory, with the sheet metal parts being produced locally from the SolidWorks files. The new energy efficient powder coating system was then installed and commissioned at the customer’s site within a few days.

Advantages of a Energy Efficient Powder Coating System from Heraeus Vulcan

All Heraeus Vulcan energy efficient powder coating systems operate using the principles of gas catalytic infrared heating. This type of system has an energy to effective heat conversion ratio of 85%, compared to traditional convection oven which is only 5% – 7% efficient. In practical operation this results in curing  taking a third less time in a gas catalytic infrared oven than a gas fired convection oven. This translates into significantly reduced energy bills.
The flameless nature of our systems means that there is no noxious emissions such as Nitric Oxide or Nitrogen Dioxide, so Heraeus Vulcan ovens are environmentally friendly.

The New Gas Catalytic Infrared Line at Flogas Britain Ltd. in Operation

Flogas Britain Ltd. approached Junair (Spraybooths) Ltd. to advise on how they could improve their current set up, which was old and effectively at the end of its useful life. The key improvements that the client was looking for included:

  • Moving from liquid to powder
  • More effective use of available space
  • Reduced operating costs
  • Improved quality
  • Added capacity

What We Did

Working with systems integrator Junair (Spraybooths) Ltd., we designed a gas catalytic infrared oven, similar to designs we have used in the past for LPG gas cylinder painting. This was integrated into a system consisting of a Zinc de-gassing oven and  Gema automated spraybooth. The infrared oven was designed by our engineers in the USA, and we provided Junair (Spraybooths) Ltd., with a complete package consisting of DXF files for the sheet metal structure of the oven, infrared heater panels and all the gas controls for each of the 6 zones within the oven.

New Wheel Refurbishment Powder Coating Plant Delivers!

Snider Fleet Solutions in Greensboro, N.C. supplies tires, retreads and vehicle services to the transportation industry. The company operates a growing auto and truck wheel refurbishment service in Bluffton, Ind.

Until 3 years ago the company utilized a single convection oven that limited production to 3,000 wheels per month. They were also experiencing very high utility bills. Dave Double, Plant Manager at Snider Fleet Solutions needed a more flexible and cost effective solution. Dave carried out his research and concluded that Vulcan Catalytic Systems (now Heraeus Vulcan) was the best choice for revamping their systems.

So, the company installed a Vulcan (now Heraeus Vulcan) Gas Catalytic Infrared Powder Coating Oven to keep up with the growing demand for wheel refurbishment. They also adopted a new overhead track from Nikotrack, which incorporated staging areas to provide flexibility in the routeing of parts through the system. This layout adopts a Lean Manufacturing approach, which ensures flexibility in batch sizes, to ensure that product is completed according the “pull” of the customer.

Wheel Refurbishment

Wheel Refurbishment Powder Coating Oven

Overall, the new system has helped production to triple with the line currently running around the clock, powder coating 9,500 wheels per month, with the capacity to exceed 10,000 wheels per month.
The full Wheel Refurbishment Case Study , published in Powder Coating Magazine, can be read here.
