Sectors

DALIC main sectors

The Dalic process is now used around the world in many different sectors.

Our technology is used in all areas of industry, and is qualified by many major manufacturers.

Most bath surface treatments can be adapted using DALIC® technology.

Aerospace

Aerospace

DALIC is a robust, reliable, and repeatable process. It is for this reason that the majority of aircraft manufacturers (OEM) have, for many years, integrated DALIC selective plating and anodising into their specifications.

Thanks to this long-term partnership, DALIC has many aerospace qualifications, whether on new or used parts.

In order to meet the specific needs of this sector, DALIC has also developed numerous ranges on high strength steel that are LHE* certified as per ASTM F519. 

*LHE (Low hydrogen Embrittlement): Hydrogen embrittlement is a metal’s loss of ductility and reduction of load bearing capability due to the absorption of hydrogen atoms or molecules by the metal. The result of hydrogen embrittlement is that components crack and fracture at stresses less than the yield strength of the metal.

Aerospace is a highly regulated sector and any surface treatment must be qualified, whether for bath treatment or selective plating, as per OEM’s specifications:

DALIC has many qualifications and capabilities in the aerospace industry. Feel free to ask the list by email.

 

 

Application

  • LHE certified Cadmium repairs (in AOG, in your facilities or in our workshop)
  • Anodising (CAA, SAA, PANTA) on new or used parts
  • Anodising on titanium

Energy & Offshore

Energy & Offshore

Energy is a very broad sector, with many product families

  • Engines
  • Compressors
  • Shafts, rods
  • Rollers, hydraulic cylinders
  • Oil and Gas
  • Rotating machinery
  • The “strong power” electrical contact

DALIC selective plating  perfectly meets the needs of these sectors in terms of design, production or maintenance.

In addition, the DALIC process is mobile and easy to use (no chemistry to be followed by the customer). It can easily be integrated on a production line, for a mobile maintenance team, or by our technician onsite. 

DALIC is qualified by VALLOUREC (VAM) according to the specification (TSLI 392 rev 2) for the copper plating of pipeline couplings.

 

Application

  • Localised treatment to bring a particular function to the part
  • Electrical continuity, hardness, anti-fretting, anti-seizing, corrosion protection, EMI/RFI
  • Defect rework : machining defect, localised impacts, poor fitting
  • Refurbishment, geometry restoration, corrosion protection, silvering

Defence

Defence

Defense includes many industrial sectors (aerospace, land army, navy, electronics).

It is characterized by a need for robustness, reliability and durability.

DALIC know-how is used by many manufacturers and armies either in the design of their products or for the maintenance of equipment.

Application

The main applications are : 

  • Cadmium plating
  • Chromic acid anodising (CAA)
  • Geometry restoration of motor frames
  • Localised Zinc Nickel touch-up
  • Plating on circuit board cases
  • Tin plating for radar insulation (EMI: Electromagnetic interference)

Marine

Marine

Metal parts used in a saline environment need to be perfectly protected against corrosion. DALIC processes will provide this protection, whether on steel, stainless steel, or aluminum.

Application

  • Repair on torpedo shells (selective plating or anodising)
  • Repair on engine shafts

Industrial cylinders

Industrial cylinders

Many trades, textile, film, paper, etc. use cylinder systems to achieve their production

It may happen that marks appear on these cylinders (wear, falling object, etc.) These defects will result in defects on the product. We can repair these defects by Dalic process.

When it comes to an impact:

  • It must first be opened. The aim is that there is no sharp angle. Indeed, the metal ions will always choose the simplest way).
  • Then, a surface preparation adapted to the material is necessary
  • we will “fill the hole” with a metal (copper, silver or nickel)
  • Once the hole is filled, we must restore the dimensions of the roller
  • a finishing step can be made to make this repair “discreet” (Nikel Cobalt Special, Zinc Nickel, Nickel)

Application

  • Seal an impact to obtain an optimal print quality
  • Make a repair barely visible

Railway

Railway

DALIC has been working with railroad manufacturers for a long time to extend the life of sensitive parts, including axles. The robustness of the process, the precision and the characteristics of the coating make it possible to improve the service life of the parts.

During maintenance operations, the axles are disassembled, and the axles are measured, they may be slightly out of tolerance. It will be possible to restore the functional dimensions of the non-compliant area by DALIC process.

 

 

Application

  • Corrosion protection of aluminum casing by anodizing
  • Corrosion protection of wheels and axles by nickel plating
  • Refurbishment of parts
  • Localised selective plating on wheels
  • Re-dimensioning of journal bearings, torsion bars, armatures, bearing seats, etc

Specific applications

Specific applications

The DALIC process can be used to restore the zinc layer that makes up the vehicle body.

The DALIC process can be used to restore machines used in the industrial process, such as industrial molds. Metal molds need a very high precision, they can be very complex to manufacture and are subjected to very strong stresses (mechanical, thermal, chemical, pressure stresses, etc.).

Many art objects may require localised application of gilding or silvering to regain its lustre of yesteryear.

Similarly, Dalic selective plating can be used on decorative objects to meet the aesthetic need. It goes from very large to very small objects.

Dalic technology can be used in a large number of different sectors and applications, feel free to contact us to evaluate the feasibility of your project:

Application

  • Car body repair: refurbishment of the damaged area with the electro-zinc plating kit (ref: E214002)
  • Repair of an industrial mold: geometry restoration, pore filling, anodizing, hardening, anti-fretting
  • Examples of repairs: A350 wing mold, helicopter blade mold, various aluminum molds, autoclave
  • Nuclear sector
