The optiselect guns

Manual coating equipment Function description
the powder gun through the powder hose . The powder is electrostatically
charged at the nozzle of the gun. In addition, an electrostatic field is
created between the gun nozzle and the grounded object. The charged
powder spray remains adhered to the surface of the object.
The powder is fluidized by air forced through a porous plastic plate from
below. The powder acquires, thereby, fluid-like characteristics.
The conveying air, supplementary air, and rinsing air are set on the control
Unit
Theprocess of the coating is like this: The powder is fluidized inthepowder hopper. The injectors transport the powder through the hosestothe guns. The guns spray a powder/air mixture onto the workpieces

A Brief About Powder Coating
Powdercoating is a dry finishing process, usingfinely ground particles ofpigment and resin that are generallyelectrostatically charged andsprayed onto electricallygrounded parts.The charged powder particlesadhere to the parts and are held there untilmelted and fused into asmooth coating in a curing oven. Before coating,the parts to be coatedare first pretreated similarly to conventionalliquid coated parts. Thepretreatment process is normally conducted inseries with the coatingand curing operatios.       
There is essentiallytwo common ways of applyingpowder coating: by electrostatic spray andby fluidized bed powdercoating. There are several other processes thathave been developed, butthey are far less used. These include flamespraying, spraying with aplasma gun, airless hot spray, and coating byelectophoretic deposition.
To get an overview of the technology used in the powder coating industry click on the items below:
  • pretreatment
  • Electrostatic Spray
  • curing
Pretreatment.
Phosphating,or conversion coating, is theapplication of an iron or zinc phosphatecoating to the substrate.Conversion coating can be a very critical partof the pretreatmentprocess, adding significantly to the performance ofthe finished coating.A phosphate coating converts the metal substrateto a uniform, inertsurface, which improves bonding, minimizes thespread of oxidation if thecoating is scratchedand improves the overallcorrosion resistance of thefinal part.
Aconversion coating can be iron, zinc,polycrystalline, chromate, ormanganese phosphate film. They aredeveloped on both ferrous (ironbased) and non-ferrous surfaces (zinc,aluminum, terne and manganese).Parts are subjected to an acidic bath anda chemical conversion forms acomplete film on the part surface,changing the chemical and physicalnature of the metal surface.
Henkelhasintroduced a big breakthrough in surfacetreatment: Bonderite NT – anew surface pretreatment which isconsiderably more efficient, lesscomplicated and more cost-effectivethan conventional iron phosphating
Electrostatic Spray
Electrostaticspray powder coating uses a powder-airmixture from a small fluidizedbed in a powder feed hopper. In somecases, the feed hoppers vibrate tohelp prevent clogging or clumping ofpowders prior to entry into thetransport lines. The powder is suppliedby a hose to the spray gun,which has a charged electrode in the nozzlefed by a high voltage dcpower.
Electrostatic powder spray guns direct theflow ofpowder; control the deposition rate; control the pattern size,shape, anddensity of the spray; and charge the powder being sprayed.The sprayguns can be manual (hand-held) or automatic, fixed orreciprocating, andmounted on one or both sides of a conveyorized spraybooth. Electrostaticspray powder coating operations use collectors toreclaim over-spray.This reclaimed powder is then reused, addingsignificantly to the powdercoating's high transfer efficiency.
Thereare various gun designs that mainly differ inthe method of applyingelectrostatic charge to the powder. In some cases,the powder iselectrostatically charged by friction. The advantage isthat the powderis free to deposit in an even layer over the entiresurface of the part,and deposition into recesses is improved.
The filmthickness is dependent on the powderchemistry, preheat temperature,and dwell time. Film thicknesses of(40 -60 µm) in case of plainpowder ( 80 – 100 µm) in case of texture cangenerally be applied on products.
Curing
Whena thermoset powder is exposed to elevatedtemperature, it begins tomelt, flows out, and then chemically reacts toform a higher molecularweight polymer in a network-like structure. Thiscure process, calledcross linking, requires a certain degree oftemperature for a certainlength of time in order to reach full cure andestablish the full filmproperties for which the material was designed.Normally the powderscure at 200°C (390°F) in 10 minutes. The curingschedule could varyaccording to the manufacturer's specifications.
The application of energy to the product to be cured can be accomplished by convection cure ovens or infrared cure ovens.
