First, let's have a brief knowledge of the powder coating oven

The workparts after powder coating will be placed in a powder curing oven, where the coating chemically reacts with heat to form long molecular cains with high cross-link density, making it tougher and more durable、

The curing job requires a high temperature (180-250℃) to melt the powder coatings, while each oven has a heating system to warm the chamber. A circulation fan is used to cycles hot air uniformly makes even temperature in the chamber to ensure uniform effect.

How to choose a right powder coating oven for you?

1. Sizes & Designs

Building a powder coating oven depends on sizes of your workparts, the size directly refers to your budget and other factors. We recommend you selecting standard modes of suppliers, which will cost less than custom sizes. But don't worry experienced suppliers like COLO are professional to design and manufacture special powder coating ovens for you.

According to different applications, powder coating ovens can be designed to batch box type, conveyor type, tunnel type.

Batch box type, batch powder coating oven suitable for small and medium business, usually configured with a paiir of trolley that carrying batch workparts moved into oven chamber.

Track type, this pass through track powder coating oven suitable for manual powder coating line

Tunnel type, applied to automatic powder coating line.

2. Heating Source

Based on heating source, commonly there are electric powder coating oven, gas powder coating oven, diesel powder coating,

For the investment of equipment itself, electric powder coating oven in small dimension is more cost-saving since it has easier structure and configurations, as gas/diesel curing oven consists of an extra heating room, heating exchanger, burner, etc.

On the other hand, many people tend to use electric powder coating ovens for small business because of the ease in getting electricity in their small workshop, which is most commonly to be founded.

For large dimension, such as oven length more than 5 meter, electric curing oven will not be cheaper than gas/diesel oven as it requries to install a big quantities of electric tube to warm the large space. We will recommend you choose gas or diesel powder curing ovens, as the energy cost of electric oven in big size will cost much higher.

Diesel oven or gas oven? For diesel heating application, it seems cost is less than LPG or natural gas, but it may create pollution to cured parts, thus gas powder coating oves are more recommended.
