As is the case with most processes, the surface coating (liquid painting / powder coating) process also starts with the base preparation – "Surface preparation". This process is the foundation of the coating process and is of utmost importance. The pretreatment process is used to remove the contamination (like oil, grease or rust) from the surface of the articles to be coated and prepare a clean base for best coating results. The pretreatment process is mainly a chemical cleaning process designed according to the chemical composition of the base material and intensity of contaminants and the capacity of the various commercially available chemicals to act on the same.

Pretreatment process can be classified into two engineering types – Dip type and Spray type. The selection between these two types is based on the article geometry, article weight, volume of production and investment, the chemical process remaining the same for both types.

These types of booths consist of square chamber, multicyclone with blower, motor & bin. Each component of the booth contributes to ensure efficient and optimized powder coating process.

The carbon steel powder coated spray chamber with the multi-cyclone recovery gives almost 100 % powder utilization. It is maintenance free and has a very long life. The powder booth is easy to clean, resulting in a quick colour change and is safe to operate. No powder spillage out of the booth and maximum recovery through the multi-cyclone results in desired pollution control.

Different Models:

Depending upon size of the article, coating requirements, material handling requirements statfield has designed some standard models. Customized booth design is also done for any non standard or specific focus requirements.

In the Dip Pretreatment process, there is a sequential arrangement of the process tanks in accordance with the designed chemical process. The articles are hung onto a load bar or are put into a cage / basket and are moved from one tank to another using overhead hoist arrangement with manual controls or with the help of Transporters with manual or automatic controls. The article is expected to remain inside the respective tank for the specified time as per the designed chemical process. Another alternative material handling mechanism is the use of overhead chain conveyors, which are dipped in the tanks. This alternative is mainly used for large sized, low volume articles.

These types of booths are available in two options

Water Wash type
Dry Back type

In water wash type, there are two chambers separated by water curtain wall. The front spray chamber for painting & Chamber behind the water curtain wall is Suction Chamber to separate paint particles from air/thinner mixture. Blower and Motor are installed on the top of the chamber.

In dry back type the water curtain is replaced with metallic filters. The dry type booth is recommended in new line paint where consumption is less or water is scarce. Metallic filters are used for arresting the over sprayed paint and give clean air output to atmosphere.

Both the types are available with Down Draft and Side Draft option.

Selection Criteria:

Selecting an appropriate type of booth depends on article size, production, type of paint and its consumption, type of application & number of operators.

Normally Dry Booth is recommended if paint consumption is low.
Water Wash Booth is preferred when higher volume of paint demands higher paint killing.
The Down Draft version is needed for large / heavy articles so as to coat article from all sides.
Side Draft booth is recommended for small articles.
Combination Model - Side Draft / Down Draft:. Sometimes there is very critical production constraints like articles weigh form 5 tons up to 5 kg. For such applications Statfield offers combined side draft booth with down draft to accommodate heavy production of different types of articles
For special applications where article size is very big, in the range of 6 meters and if civil pit for down draft is to be avoided, Statfield provides option of sideward draft towards bottom of the booth panel. Additional pressurization ensure dust free operation

Features:

Sturdy design
Highly durable
Application specific design 

Ovens are used for firmly baking the layer of powder/paint onto the article surface. Convection heating is used for curing of the powder / paint film. Hot air is blown over the articles thereby heating the articles. Circulation air blowers draw the cooled air over the heat exchanger or bank of electrical heaters. The heated air is passed into the hot air ducts and let out into the oven through the air directional blinds.

The ovens supplied are suitable for conveyorised / batch operations using Electrical / HSD / LPG / IR Heaters / Thermic Fluid heating System

Salient features of Intech's Oven

• Quick heating and lower losses through air-tight housing.
• Performance testing and assurance prior to dispatch.
• Uniform air circulation through the unique adjustable air direction blinds.
• Low RPM blower used for smooth and noiseless operation.
• Structure made out of channeled frame work from inside for better strength and rigidity.
• Simple and fast assembly with unique cassette section design

Overhead chain conveyors are the most efficient and convenient systems for material handling in any type of surface coating plants. A well designed conveyor system and its well thought over layout can enhance efficiency of any surface coating plant. Rate of production, available production space, size & weight of the article to be coated play an important role in the selection of the conveyor system.

Some important types of conveyors are

• Free Track & Trolley system for batch operation
• Mini-rail Overhead chain conveyors for light weight articles
• Aero-rail Overhead conveyors for medium weight articles
• Heavy Duty I-Beam conveyor
• Power & Free Overhead chain conveyor systems
• Transporter system for pretreatment
