FINISHING SERVICES:
Final processing and post-treatment operations
Finishing services provide the final functional and aesthetic enhancements applied to components after their main surface treatment, after the main surface treatment, including laser demasking, pad printing, stone-chip coating, cavity waxing, and DMC marking.
Process steps
Our finishing operations are the final steps in the surface treatment chain, designed to add functionality, durability, and precision detailing.
Depending on the customer’s requirements, we perform secondary finishing processes such as laser demasking, pad printing, anti-chip coating, cavity waxing, and barcode/DMC marking.

FAQ
What are the benefits of using laser demasking services for selectively removing coatings compared to traditional masking techniques, especially for complex geometries or high precision requirements?
Laser demasking allows precise and selective removal of coatings without mechanical contact, making it particularly suitable for complex geometries and high-precision areas.
Compared to traditional masking techniques, it eliminates the need for tapes or plugs, reduces the risk of coating damage, and ensures clean, repeatable edges. Laser demasking also improves process consistency, reduces manual operations, and is well adapted to automated or high-volume industrial applications where accuracy and reliability are critical.
Can your pad printing services (tampography) apply durable logos, part numbers, or warning symbols on various coated or plated metal surfaces, and what is the typical resolution or detail achievable?
Yes. Our pad printing (tampography) services allow the application of durable logos, part numbers and warning symbols on a wide range of coated or plated metal surfaces.
The process is well suited for complex shapes and small areas, providing good adhesion and long-term legibility. It enables fine details and consistent marking, with the achievable resolution defined according to the surface condition, coating type and functional requirements.
How does your anti-chip coating (anti-gravillonage), especially the Hydrosol type for vehicle underbodies, protect against stone chip damage and corrosion, and how does it integrate with other protective coatings?
Anti-chip coatings, including Hydrosol-type systems, protect vehicle underbodies by absorbing impacts from stone chipping and reducing damage to underlying coatings.
They form a flexible and resistant layer that limits coating breakage and helps prevent corrosion initiation. Anti-chip coatings are typically applied as part of a multi-layer system and integrate well with E-coat or paint layers, contributing to overall durability and long-term corrosion protection in harsh road environments.
What is the purpose of cavity waxing services (cire dans les corps creux) for components like automotive chassis or hollow industrial parts, and how does it enhance long-term internal rust proofing?
Cavity waxing is used to protect the internal surfaces of hollow components, such as automotive chassis parts or enclosed industrial structures, where standard coatings cannot fully reach.
The wax penetrates seams, joints and internal cavities, forming a moisture-repellent protective film that helps prevent corrosion from starting inside the part. Used as a complementary treatment, cavity waxing significantly improves long-term internal rust protection and extends service life in corrosive environments.
What types of barcode generation or DMC (Data Matrix Code) marking services do you offer for part traceability and identification, and are these marks durable enough to withstand industrial environments after the main surface treatment?
We offer barcode and Data Matrix Code (DMC) marking solutions designed for part identification and traceability in industrial environments.
These markings can be applied using adapted marking technologies and are designed to remain legible after surface treatment and during service life. Their durability depends on the marking method, the coating system and the operating conditions, ensuring compatibility with industrial handling, corrosion protection processes and traceability requirements.
