Enter the weight of the part before and after coating and the total weight of the powder in the bag into the calculator to determine the powder coating transfer efficiency rate.

Powder Coating Rate Formula

The following equation is used to calculate the Powder Coating Rate.

TE = (M2-M1) / M3 *100
  • Where TE is the transfer efficiency/coating rate (%)
  • M2 is the mass of the part after coating
  • M1 is the mass of the part before the coating
  • M3 is the mass of the powder in the bag.

To calculate the Powder Coating Rate, divide the mass of the powder deposited by the mass of the powder in the bag, then multiply by 100.

What is a Powder Coating Rate?

Definition:

A powder coating rate is defined as either the total weight of powder deposited per unit of time or the total percentage of powder in a bag used per part.

How to Calculate Powder Coating Rate?

Example Problem:

The following example outlines the steps and information needed to calculate Powder Coating Rate.

First, determine the initial weight of the part. In this example, the part ways 10kg.

Next, determine the weight of the part after coating. This is found to be 12kg.

Next, determine the weight of the powder in the bag. This is calculated to be 40kg.

Finally, calculate the Powder Coating Rate using the formula above:

TE = (M2-M1) / M3 *100

TE = (12-10) / 40 *100

TE = 5 % per part

FAQ

What factors can affect the powder coating transfer efficiency rate?

The powder coating transfer efficiency rate can be affected by several factors including the type of powder coating used, the application method (e.g., electrostatic spray, fluidized bed), the thickness of the coating, environmental conditions (such as humidity and temperature), and the skill level of the operator.

How can I improve the powder coating transfer efficiency rate?

Improving the powder coating transfer efficiency rate can be achieved by optimizing the application process, which may include adjusting the electrostatic charge settings, ensuring proper grounding of parts, using powder coatings with properties that match the application requirements, maintaining optimal environmental conditions, and providing training for operators to improve their technique.

Why is it important to calculate the powder coating transfer efficiency rate?

Calculating the powder coating transfer efficiency rate is important for several reasons. It helps in assessing the cost-effectiveness of the powder coating process, ensuring the quality of the coated parts, minimizing waste of powder materials, and improving the overall sustainability of the process. Knowing the efficiency rate can also help in troubleshooting coating issues and optimizing the coating process for better results.
