Dip painting lines

Dip painting is highly economical and ecological way of painting which belongs among the latest surface treatment processes. The main area of application is particularly automotive industry, household appliances, electrical devices, heating radiators, agricultural and construction machines, metal furniture, structural elements etc.

Fulfillment of the highest quality requirements enables an application of electro-dip coating mainly by means of cathodic dip painting. The goal of this process and layer properties makes this method unique.

Cycled operating lines feature high flexibility and suitability for lower throughputs, wide range of parts or large dimension parts for treatment.
Continuous operating lines using overhead chain conveyor are suitable for high productivity, high capacity requirements and for high throughputs of same or similar parts.

We deliver turn-key delivery systems incl. pretreatment sections, paint ovens, exhaust air treatment, conveyors and manipulation units, control system and process visualization, water treatment and waste water treatment plants.

We deliver lines for:

Cataphoretic coating (e-coating, KTL)
Anaphoretic coating (ATL)
Dip painting

Electrophoretic

Electrophoretic coating lines are highly efficient and cost-effective. Electrophoretic painting is particularly suitable for the protection of steel, galvanised and aluminium components. Cataphoretic painting is used as a base coat for painting. However, cataphoretic painting can also be used for one-layer painting.

The main advantages of cataphoretic painting

minimal environmental impact due to very low solvent content, minimal emissions, solid waste and waste water
high corrosion resistance of the coating (over 1000 hours in salt spray) with a relatively low thickness
uniform coating thickness over the entire surface, including hard-to-reach areas, edges and corners, even on complicated parts, thickness controllability
high adhesion and mechanical resistance of the coating
high cost-effectiveness - minimal paint loss due to practically closed material circuit (practically 100% paint recovery)
easy automation and process control, low labour and low requirements for operating personnel
no droplet or "veil" formation
possibility of top coating with different types of varnishes
safety - no fire or explosion precautions or special measures for occupational safety are required
low impact on the working environment

Continuous lines

Continuous lines for paint dipping are highly productive. They are suitable for large series of similar goods. Transport of goods is done by over-head either single-track chain conveyor or Power&Free conveyor.

Pretreatment section can be done either by jet spraying or with combination spraying-dipping.

Cycle operated lines

Cycle operated lines are highly flexible and programmable. Cycle operated lines are suitable for large and highly variable sortiment of goods. Transport of goods between baths is managed by transport manipulators as in electroplating lines.

Pretreatment is achieved by dipping.
