Metal pretreatment

Tunnel pretreatment

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

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.

Chamber pretreatment

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.

Washing room

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.
