What equipment is needed for powder painting of metal furniture

1st stage: preparation

Preparation is the most important step in powder painting. If something goes wrong here, the end result will be disappointing.

In order for the paint to fit well on the surface, it must be carefully prepared. For this step, the powder coating area must be sandblasted or shot blasted. They can be used to remove old paint, dirt, dust, oil stains.

After sandblasting or shot blasting, the product must be degreased, if necessary, treated in a chromating or phosphating solution.

For this, you need a bath of preliminary preparation. You can, of course, prepare products by hand, but this is a laborious process.

After processing, before applying the powder, the product must be dried in a drying chamber so that all moisture evaporates. Otherwise, the powder may not settle well on the surface.

In industries with a large work flow, it is advisable to install an automatic surface preparation line. They are equipped with everything necessary for the pre-processing of equipment products and have transport systems. That is, the operator only needs to control all stages and correct if necessary. This greatly speeds up the whole process.

2nd stage: staining

The powder is applied to metal elements in a special spraying chamber. It is designed in such a way as to minimize the consumption of paint and varnish material, and at the same time ensure the uniformity of the coating.

 

 

In addition to the camera, a spray gun is needed to spray powder. It can be manual or installed in an automatic powder coating line. Also, pistols differ in how they work. They can be tribostatic or electrostatic. The former are suitable for coloring small products of complex shapes, because they are not connected to the network and are limited by the volume of the tank. The latter work from the network and do an excellent job of painting large parts of a simple shape. Read more about which spray gun to choose here.

3rd stage: drying

In order for the powder paint to adhere to the surface of the product to be painted, it must be baked at a high temperature. This requires a polymerization oven.

A painted product is placed in it for 15-30 minutes. During this time, under the influence of high temperatures, the powder melts, forms a film and solidifies. This creates a durable powder coating that protects the painted product as much as possible.

The polymerization oven can be infrared or convective, electric or gas. It is necessary to select the required model based on the specifics of production and painted parts.

In automatic lines, all these stages are usually connected by one transport system. This significantly improves the quality of the final result and saves a lot of time. Therefore, in large industries, it is better to equip areas for powder painting of metal furniture with just such systems.

 

Painting metal furniture or its individual parts makes it possible to protect products from rust and, accordingly, to increase their service life.

In addition, with the help of staining, you can completely restore the appearance of old furniture.

Powder paint is most suitable for painting metal furniture. Because it creates the most durable and durable coating, regardless of how and in what places the painted products will be used.

Powder painting is always several stages that the product to be painted must go through.

Powder painting of metal furniture includes the following steps:

• Product preparation
• Coloration
• Drying

Each of these stages requires its own special equipment. We will tell you which one below.
