Although powder coating belong to low pollution surface treatment, we still hope to reduce the amount of the pollution year by year to treat our environment friendly. We have installed the wastewater recycling system, which recycles the wastewater from pre-treatment to get zero emission, the recycling cyclone separator, to reduce the production of waste powder, using clearly energy natural gas to give energy, and professional air processing equipment, which can clear the waste air. Our spirit is “Take it from society and give it back to society”. It’s our goal to get along well with our environment.
Pre-treatment process, which removes the oil and corrosion from the material, is essential to powder coating. The surfaces of aluminum and metal material usually have many problems such as oil, dirt, lubrication greases, metal oxides, welding scale etc, and these problems are made by the casting, stamping, delivery, storage and other process. In order to improve the combination of material and anti-corrosion ability, it needs to be completely removed the oil and dirt out before coating. Therefore, we know the pre-treatment is very important in the powder coating process.
Pre-treatment usually divided into spray, bathing and submersion application. In Shan Jie, we use the spray application in our pre-treatment, which is the 70 meter length process of degreasing and phosphating. In addition, the advantage of long pre-treatment line can apply variety of material and size products. As well as, we maintain the equipment in pre-treatment every week for improving washing efficiency.
The first drying process is removing the water from the material after pre-treatment. Usually, there are infrared ray furnace and hot air circulation drying furnace. We use the hot air circulation drying furnace to dry the water from the material with 120℃to 150℃ and heat the material to improve the effect of combination between powder coating and material.
Powder coating process needs to prevent coating on some parts of products because of product design such as the electric connection or connection of structure. Therefore, it’s an important part of powder coating, how to completely prevent the powder to absorb on the right part. Therefore, we will dependent on the powder types and the materials to choose the suitable way to avoid the powder. In general, we can use by high-temperature tape (480℉ (250℃)), high-temperature stopper and lid to avoid powder efficiently. Even more, we can help customer to design customized hanger and stopper for their requirement as well as the thickness. If customers need to thin or thick, we will give our customer high quality service.

We use the semi-automatic spray equipment and recycling cyclone separator (ZYL). We can overcome the dead angle since use the semi-automatic. Moreover, the specialty of recycling cyclone separator is quickly and efficiently changing color. At the same time, it can improve the powder recycle and reduce the pollution since we use the recycling cyclone separator.

When the spayed materials go into the oven, the temperature is 200℃ and the time between 15 to 20 minutes. And then, it will be cold down on the conveyor. However, we will change the condition of oven according to the powder’s specialty and the product’s material.
We inspect the color, thickness and surface after powder coating. If customers need other tests such as cross hatch test, salt spray test and hardness test etc, we will help them and achieve their needs. High quality management and servicing customer are always the firmly concepts of Shan Jie
