The process is portable, does not use immersion tanks, and with over 50 pure metals, alloys, and anodised coatings is used for repairs, resizing, resurfacing, rebuilding, or protective plating of any metal object. The atomic bond created between the basis metal and the applied coating has the cohesive strength of the base material itself, this produces deposits equal to and in many cases superior to bath plating. Hand-held tooling permits accurate control of deposit thickness offering the finest of tolerances on localised areas often eliminating the need for pre and post machining.
The process carried out on-site and "in-situ" offers many advantages:
It can be used without complex masking or the fear of over spray.
It often does not require machine dismantling
It does not generate excessive heat
It plates to precise engineering tolerances and finishes
It can be used selectively to build up unevenness
It can build out impact or corrosion craters
It can deposit any thickness from a trace upwards
It can deposit thicknesses in excess of 2milimeters+
It complies with many Industrial, and Military specifications including MIL-STD-865C, and has the approval of many Civil Aviation Authorities world
Overall the DALIC system offers the engineer a simple non-elaborate technique for applying electrodeposits only where they are required. Its use can in many instances save hundreds or even thousands of dollars by reducing production downtime delays, salvaging rejects, saving on rework costs and cutting down on expensive transportation.
Perhaps the engineers at the Rolls-Royce Engine Company who called it "The precision Engineer's Putting-on-Tool" created the best description of all.
Full production system can be designed for most needs with on site training available for the operators, who require no specialised pre qualifications.
The following represents a broad view of the marketing areas for the Dalic brush plating process:
General Engineering
Damaged bearing surfaces can have the damaged areas selectively repaired to tolerance without the need to remove further metal. The metal used to repair can in its self offer greater wearing properties.
Under or oversize journal areas can be resized to tolerance often without the need to re-machine also again the metal used to repair can in its self offer greater wearing properties.
Fretting corrosion on journal surfaces can be dramatically reduced by the application of a thin layer of say tin.
Hard wearing surfaces can be repaired or applied.
Corrosion protection metals can be repaired or applied over cheaper base materials.
Print and Packaging industry
Selective repairs to impact damage on print cylinders. This is a very big part of the business in this industry mainly because of three factors:
Timeliness: repairs can be made within hours of the damage occurring.
Because of the finely balanced alignment of the print cylinders removal can be very expensive and replacement also expensive.
Organic repairs (glues, epoxy, etc) often do not wear well and can ‘fall out' causing further damage
Electrical or Power Generation Industry
Down load PDF
Large users of silver for electrical contacts on high voltage switching gear and general contact points.
Repairs and resizing of above on-site and in situ.
Also used in the engineering side of this industry mainly foe resizing of journal areas.
AIRCRAFT INDUSTRY
The Dalic process is called for in the maintenance manuals of all major aircraft manufacturers and as such the procedures for correct applications and the particular solution required are laid down.
Main use is the cadmium plating of high tensile steels because of its ability to NOT induce Hydrogen Embrittlement.
Build up of worn parts using various nickels and their alloys. Particularly valuable in the helicopter industry because of its ability to plate on to aluminium's.
Plating copper on to aluminium using the Dalic process allows for good electrical connections (it is difficult to impossible to solder directly on to aluminium but plate a patch of copper on and no problems)
Again aluminium is difficult to impossible to gain an effective bond using adhesives whereas anodised aluminium can be effectively glued. Dalic anodising offers an on site method to effect patch repairs to aircraft skins.
DIE OR PLASTICS INDUSTRY
Resizing of worn areas.
Repairs to impact damage.
Applications of metals such as chrome, nickel or other alloys to reduce plastic adhesion or for use in high temperatures.
MOTORCAR INDUSTRY
Application of zinc to replace manufacturers original specifications when damaged panels are repaired.
As per engineering industry resizing and hard wearing surfaces
For decorative purposes ie. Gold plating of badges and emblems.
SHIPPING INDUSTRY
As per engineering industry but perhaps of greater value as the parts ie propeller shafts drive trains etc to be plated can only be removed from the ship in a dry dock and then with great difficulty and expense so plating on-site and in-situ offers significant savings.
Corrosion protection particularly in the navel arena
HYDRAULICS
Minor but still incapacitating impact damage can be removed in a relatively short space of time also without the costly requirement of stripping the ram off the machine and disassembling.
Internal damage can also be fixed.
RAINLWAY INDUSTRY
Resizing of axels without prior removal of metal.
Repairs and resizing of journal areas on electric drive train motors.
Also as per engineering specs.
MINING INDUSTRY
Re sizing of large components also hard wearing applications.
Because of the massive nature of machinery fretting corrosion is a significant problem therefore Dalic is used to alleviate this area.
Repairs and resizing of journal areas on electric drive train motors.
Electrical and or Computer Industry
Mainly used to gold plate sensitive electrical connectors.
Silver plating to the commutator.
