Pretreatment - general information

When AABO supplies a complete finishing plant, a pretreatment system is often included.

The requirement for pretreatment depends on the materials that are to be treated and the standards required of the end result. AABO’s pretreatment offering encompasses a wide range of specialised processes which are carefully identified from project to project. Pretreatment may involve washing down dirt and dust or multi-step chemical pretreatment. It may also involve manual grinding, fully automated blasting of production items or conversion and/or primer coatings.

All forms of pretreatment each prepare the surfaces of the workpieces for the final top coating/finishing.  This ensures the required quality of the finishing. 

At AABO, we consider and apply all types of pretreatment in our customer-specific solutions and in our final designs. These various customised solutions are either procured externally or manufactured by AABO. 

Some of our solutions are described below. These include:

Washing room

A washing room works in the way that all workpieces are placed in a separate room, access doors are closed and the operator carries out a manual washing process.

This washing process may consist of one or more processes where all processes are carried out in the same chamber. The operator carries out the washing process by using an integrated high-pressure cleaner which usually offers 1-3 processes.

Chamber pretreatment

Chamber pretreatment processes generally involve workpieces being placed in the chamber of the machine, access doors being closed and the process starting.

These chamber pretreatment processes may consist of one or more cascade processes where all processes are carried out in the same or several separate chambers. The advantage of using chamber pretreatment is that they are suitable for situations involving either batch runs or where factory floor space is at a premium.

Tunnel pretreatment

Tunnel pretreatment processes generally involve workpieces being continuously fed through the pretreatment tunnel in which they undergo integrated finishing processes. 

The processes involved in tunnel pretreatment may consist of one or more cascade processes where each process is carried out in separate tunnel sections. The advantage of this finishing type is that it is suitable for situations in which assembly lines require high levels of productivity.

Dip pretreatment

Dip pretreatment processes generally involve workpieces being fed through the system using overhead cranes. Items are dipped in separate tanks to undergo the integrated finishing processes. 

The processes in dip pretreatment systems may consist of one or more fluid processes where each process is carried out in separate tank sections. The advantage of using this type of processing is that it is suitable for situations involving assembly line production requiring high levels of productivity and situations involving production items of such a nature (length, height, weight etc.) that handling of the products is of paramount consideration.
