Powder and paint.
From one-offs
to series.

1. Step 01Vaporise

   In the sump of the unit, the solvent is heated to boiling point. It rises as vapour and fills the working zone.

2. Step 02Condense

   The cold part is lowered into the vapour. The vapour condenses as liquid on the part — on every surface it reaches, and it reaches every one.

3. Step 03Dissolve

   The condensate dissolves oil, grease and drawing compounds and runs off downwards with them. No pressure, no mechanics, no edges left in the shadow.

4. Step 04Recover

   In the sump, the solvent is distilled and flows back into the circuit clean. The part warms up to vapour temperature and is dry when it comes out.

Material restrictions: Some plastics and elastomers do not tolerate solvent. Resinified residues, mill scale and old coatings are not removed by degreasing — that requires blasting or pickling beforehand. We clarify both before the first batch.
Unit: closed, with cooling zone and freeboard area, fully automatic cycle, operated in accordance with the 2. BImSchV (German emission-control ordinance).

1. Step 01Hanging

   The part is attached to the rack so that it is securely earthed and drains cleanly. Where the contact sits, a spot remains uncoated — we agree the hanging points with you in advance.

2. Step 02Charging

   In the gun, the powder is electrostatically charged. The earthed part attracts the particles; they follow the field lines and settle on averted surfaces and edges too.

3. Step 03Curing

   In the continuous curing oven, the powder melts, flows into a closed film and cross-links chemically. What matters is the temperature in the part, not in the oven — thick parts take longer than thin ones.

4. Step 04Inspection

   After cooling, we check coating thickness and appearance. Only then does the series continue along the conveyor.

Advantages: solvent-free, mechanically far more resistant than wet paint, one application instead of several coats, clean edge coverage, consistent coating thickness across the entire series.
Material restrictions: The part must be electrically conductive and withstand the curing temperature — plastics, electronics and heat-sensitive assemblies are ruled out. Deep inside corners shield the electric field and end up with a thinner coat; there we recommend wet paint. Custom colours only pay off above a minimum quantity.

1. Step 01Masking

   Fits, threads and sealing surfaces are taped off or plugged according to the drawing. This step determines a large part of the price — the clearer your specification, the more accurate the costing.

2. Step 02Priming

   The adhesion primer is matched to the material: steel, aluminium, galvanized steel and plastics each need a different system. This is where corrosion protection comes from, not from the topcoat.

3. Step 03Application

   The topcoat is applied in several passes with flash-off times in between. The booth's oil curtain captures the overspray so it doesn't fall back onto the part as dust.

4. Step 04Drying

   Depending on the system, the paint dries in air or in the oven at moderate temperature. Two-component systems cross-link chemically and only reach their final hardness once the reaction is complete.

Advantages: any colour and any effect, even in very small quantities, low temperatures for sensitive materials, plastics and mixed assemblies in one pass, very thin coats, repairable. In the cleanroom spray booth for parts where a single inclusion means a reject.
Points to note: mechanically more sensitive than powder, more operations and therefore more expensive for large series, longer lead time due to flash-off and drying times.
