How We Powder Coat Wood

We often get, “I didn’t know you could powder coat wood!” Most people are familiar with metal powder coating but powder coating on wood was introduced to the market in early 2000s. DVUV was one of the initial companies to enter the MDF powder coating market. To date DVUV has provided millions of powder coated wood components to a variety of industries.

The Process

Our unique UV cure powder coating finishing process turns raw MDF and Birch Plywood components into finished parts in only 20 minutes. A one coat single step coating with no primer or top coat required.

Step 1 – CNC Machining

Process - Step 1 - We take your drawings and CNC machine the parts to your exact specifications.

We take your drawings and CNC machine the parts to your exact specifications. We use high quality MDF to ensure your parts machine well and look the best after powder coating.

Step 2 – Preparation

Process - Step 2 - Part may require light sanding or prep work before it enters the powder line

Depending on the part, a light edge sanding may be required for optimum finishing. The parts are then hung on the automated powder line and blown off with compressed air to remove any surface containments.

Step 3 – Preheat

Process - Step 3 - Preheating the wood or MDF helps the powder coating adhere to the surface

Since wood is non-conductive, a preheat is required to promote conductivity. The part continues on the conveyer line and enters a preheat oven at a low temperature for 1 minute. This draws the moisture in the wood to the surface of the part and allows the powder to adhere.

Step 4 – Powder Application

Process - Step 4 - Powder coatings are applied electrostatically

The parts then enter the spray booth and powder is applied electrostatically using automated spray guns. The charged powder seeks a ground and attracts to the part.

Step 5 – Melt Phase

Process - Step 5 - Part continues onto the melting phase where low-temp heat helps the powder stick

Continuing on the conveyer line, the part enters an oven where the powder is melted at a low and controlled temperature for 1 minute. Since wood is heat sensitive, it’s important to limit and control the time and exposure to heat.

Step 6 – UV Cure

Process - Step 6 - After the melt, the part is immediately passed in front of UV light to be cured

Immediately after the powder is melted, the part passes in front of a bank of UV lamps where the part is instantly cured by UV light.

Step 7 – Unload & Pack

Process - Step 7 - Parts are inspected & then packed for shipment

Finished parts are unloaded, inspected and packed up for the customers. The entire wood powder coating process takes only 20 minutes from start to finish.
