Shengen learns spraying techniques and creates his own spraying department

In order to ensure the quality and efficiency of product spraying, Shengen Metal Co.,Ltd worked hard to research technology, and finally obtained the ISO9001:2015 certificate and has its own spraying department.

What are Powder Coatings?

Powder coatings are created using polymeric resins that are combined with pigments, curatives, flow modifiers, leveling agents, and additional additives. They are both solvent- and water-free systems. Their deposition produces a continuous, durable, anti-corrosive, and abrasion-resistant high-quality surface finish on metallic substrates.

What is the Coating Process?

There are two main powder coating practices, and the selection is usually based on part size and geometry. Big workpieces need the use of a controlled, factory-applied process known as electrostatic spray deposition (ESD). The coating method is made up of a micronized powder coating applied using a spray gun, whereby the powder is drawn to a grounded element through an induced electrostatic charge. Acrylics and polyesters are typically employed when coatings are decorative in nature.For industrial applications, epoxies are the norm, with hybrid resins gathering interest.

The coating is consistent, the procedure is effective and environmental exposure is reduced in both spraying and dipping. Following the application of the powder coating, parts go into a curing oven in which the polymer resin chemically reacts, creating a uniform, homogeneous coating of long molecular chains with greater cross-link density. The part can then be put into service.


Shengen Metal Co.,Ltd has its own dedicated spraying department, and the spraying technology is certified by ISO9001:2015 certificate. At the same time, as an environmental protection company, the powder used for spraying is also environmentally friendly and will not cause any pollution to the environment.
