WOB-Wessling Surface Finishing

What WOB-Wessling Surface Finishing does

WOB-Wessling Oberflächenveredelung GmbH is a family-owned German industrial contract coating service provider headquartered in Geeste-Dalum, Lower Saxony, operating since 2004. The company runs what it describes as the probably largest cathodic dip coating (KTL) contract coating facility in Europe, featuring a 16m × 2.6m × 3.6m dip tank capable of processing components up to 11,000 kg, complemented by robot-assisted powder coating lines (PK1-PK5), wet painting capacity up to 25 × 20 × 5 meters, metallizing via arc spraying, and comprehensive pre-treatment (mechanical blasting, chemical pickling, degreasing, zinc phosphating) and post-treatment (seam sealing, masking, assembly) services.

The company serves industrial B2B customers across multiple verticals including rail vehicle manufacturing (trams and train power units), military technology, commercial and specialty vehicles, automotive components, mechanical engineering, agricultural machinery, and offshore wind/energy. Specialized offshore coating combinations meet DIN EN ISO 12944 CX standards for marine environments. The company is DIN EN ISO 9001:2015 certified and is implementing ISO 14001 and ISO 50001; it maintains an EU-funded research collaboration with HTW Dresden since 2012.

WOB operates a fee-for-service contract coating (Lohnbeschichtung) revenue model with quote-based pricing tailored to component specifications, coating type, and batch complexity, supported by its own 10-truck EU logistics fleet for component pickup and delivery. Sales are conducted via direct enterprise field sales targeting engineering and manufacturing customers, with multi-year contracts as the typical billing cadence. Ownership rests with the Wessling family, with Klaus Wessling Sr. as Managing Director and second-generation family members in leadership.

Core offering

WOB-Wessling operates Europe's likely largest KTL (cathodic dip coating) contract coating facility, offering industrial surface finishing services including KTL electrocoating, robot-assisted powder coating, wet lacquering, and arc-spray metallizing. The integrated service covers mechanical and chemical pre-treatment (degreasing, zinc phosphating, pickling, blasting), seam sealing, masking, assembly, and an in-house logistics fleet for component pickup and delivery within the EU.

Product overview

WOB Wessling Oberflächenveredelung operates as a surface finishing service provider with the probably largest KTL (cathodic electrocoating) job coating facility in Europe. The company offers an integrated system of surface treatment services centered on KTL coating and powder coating as core processes, supported by comprehensive preparation services (mechanical and chemical surface preparation including degreasing, zinc phosphating, pickling), process services (seam sealing, masking, metallizing, wet lacquering), and finishing services (assembly, transport logistics). The facility features a 16-meter immersion tank for XXL components up to 11,000 kg, robot-assisted powder coating systems, and handles components across rail vehicle, military, commercial vehicle, automotive, machinery, and agricultural equipment industries.

Functional benefit

Products and services

• KTL Coating (Kathodische Tauchlackierung / Cathodic Electrocoating) Cathodic dip coating process where components are immersed in an aqueous paint bath under direct current voltage, yielding a uniform 10–40 µm layer with excellent corrosion resistance. Targeted at industrial OEMs requiring maximum corrosion protection for XXL and complex-geometry components in rail, military, commercial vehicle, automotive, machinery, and offshore applications.
• Powder Coating (Pulverbeschichten) Powder coating for electrically conductive substrates (steel, aluminum) applied in modern booths and cured at approximately 190°C, producing a durable, scratch- and weather-resistant surface. Delivered via robot-assisted systems for consistent quality and reproducibility at series scale.
• Wet Painting (Nasslackieren) Wet lacquer coating with individually tailored solutions for layer build-up, surface quality, color, and protection duration. Suited to large and heavy components with custom color and finish requirements, also used in combination with KTL for offshore applications.
• Metallizing (Arc Spraying) Thermal arc spraying process where aluminum or zinc-aluminum alloy wire is melted via electric arc and applied with compressed air, producing a high-friction, highly corrosion-resistant metallic coating. Used in combination with KTL and topcoats (e.g., Nordicoat) for extreme marine/offshore environments.
• Mechanical Surface Preparation (Blasting & Grinding) Mechanical pre-treatment using a range of blasting media (steel corundum, desert sand, glass beads, plastic granules, VA, grit) plus grinding to clean and roughen component surfaces prior to coating.
• Chemical Surface Preparation (Immersion & Spray Pickling) Chemical pre-treatment via immersion pickling (Tauchbeize) and spray pickling (Sprühbeize) to remove oxide layers, scale, rust, and contaminants and create a protective iron phosphate layer before coating.
• Degreasing (Entfetten) Chemical degreasing using alkaline hot immersion baths with heat and surfactants to reliably remove oils, greases, and light contaminants from components prior to coating.
• Zinc Phosphating (Zinkphosphatieren) Conversion coating process that deposits crystalline or amorphous inorganic zinc phosphate salt layers on metal surfaces, optimizing coating adhesion and underlying corrosion protection.
• Seam Sealing (Nahtversiegeln) Sealing service that closes capillaries and joints between components using soft silicone-like or hard sealant variants to ensure optimal corrosion protection in coated assemblies.
• Masking (Maskieren) Masking of functional surfaces such as threads, fits, screw faces, and moving components using heat-resistant tapes, silicone plugs, paper, wood, metal, or 3D-printed masks to keep them free of coating during processing.
• Assembly (Montage) Post-coating assembly and finishing services, including repackaging components into original delivery containers and providing just-in-sequence transport, plus general finishing and assembly work.
• Transport Services (Transporte) In-house transport service within the EU using a fleet of 10 company-owned trucks (curtain-sided semi-trailers and low-bed trailers) for component pickup, delivery, and just-in-sequence supply to/from the Geeste-Dalum facility.

• Voestalpine AG: Austrian steel and technology group with significant metal processing and surface treatment operations serving rail, automotive, and industrial customers. Comparable broad incumbent with in-house coating capability that competes with or complements WOB's contract services.
• Praxair Surface Technologies (Linde plc): Global provider of surface treatment services including thermal spray coatings and engineered finishes for aerospace, industrial gas turbines, and automotive. Comparable broad incumbent in contract coatings with metallizing overlap to WOB's arc spraying capability.
• Oerlikon Balzers: Swiss-based global surface solutions business offering PVD, CVD, and other advanced coatings for tooling, automotive, and industrial components. Comparable broad incumbent in industrial contract surface engineering, though focused on thin-film rather than liquid/powder coatings.
• Bodycote plc: Global leader in heat treatment and specialist surface technologies serving aerospace, automotive, and industrial customers. Comparable as a broad incumbent offering overlapping metal finishing services, though weighted toward thermal processes rather than KTL/powder.

Others

• Dürr AG: German manufacturer of industrial painting and coating systems, including complete automotive paint shops. Related as equipment supplier and turnkey coating plant provider to many of the same end markets WOB serves as a contract coater.
• Henkel AG & Co. KGaA: German multinational supplying surface treatment chemicals, pretreatment products, and coating technologies used by WOB and its customers. Related as an enabling chemistry supplier rather than a direct contract coater.
