Gloss Chrome Plating
Thin film, conventional chrome plating has application for a number of industrial applications , from hydraulics and machine equipment to blow moulding and plastic injection moulding. Our most frequent use of this coating is for maintaining high gloss levels in plastic moulding related applications. Conventional Chrome has the advantage over PVD coatings as it has the ability to accommodate larger items and is a “cold” process.
We are able to plate on to all steels and also directly onto wrought aluminium of the 600 and 700 Series. Pre-polish is critical and usually customers responsibility to provide the finish that is needed.
Contact us to discuss you’re specific need as not all jobs are possible. Please note that we DO NOT CHROME CAR PARTS. This is decorative chrome plating and is different in function and application to the thin chrome flash plating that we offer.
Dry Film Lubricant
Certain applications call for localised decrease in friction to decrease galling and seizure. We have solved some of these problems with the addition on Dry Film Lubricant to the working surfaces. Metal Sulphides of submicron diameter are worked into the surface and mechanically bond to the surface. We have mainly used Tungsten Disulphide for very tight tolerance items
Resin Bonded Coatings
Lubrication & seizure resistance
Molybdenum Disulphide (MoS2)
Moly disulphide coatings for certain applications where large pressures are seen without abrasive action, resin bonded lubricants are also an alternative. These coatings can retain oil lubricant in the surface, as well as dry film lubricant particles. In addition they offer significant corrosion protection and provide high pressure slip even at elevated temperatures. The resin is thermally cured and can handle sustained high temperatures up to 450°C. Coating thickness approximately 12-25 Microns. Equivalent trade names could include Molybond, Molykote, everlube, Lube-Lok, Perma-silk, Ever-silk etc. Call to make sure we match your requirement.
PTFE (Teflon) Coating
Thermally cured resin containing PTFE and other compounds are also used to solve problems relating to high corrosion resistance, low friction, anti-seizure, non-stick/release properties, wear and heat resistance. These coatings are primarily designed for fasteners but can obviously have other applications where their properties are advantageous.
similar trade names could include Xylan, Teflon coating etc.
High Temperature Insulation and Dispersion
Where localised heat is seen and temperature distribution is to be encouraged as well as providing corrosion and high temperature oxidation resistance, a Dispersion coating can be used. These coatings contain ceramic particles with high thermal conductivity whilst the high temperature resin provides excellent binding to the substrate and provides the corrosion and oxidation seal.
Conversely it may be advantageous to provide an insulating effect to discourage heat flow through a surface. Here different ceramics particles are used with very low thermal conductivity. These coatings can take very high flash temperatures well over 1000°C. Due to the coatings thin nature (25 microns) it is not a solution for efficient sustained thermal insulation, but more for instantaneous thermal reduction. If temperatures are below 200°C then different binders can be utilised and coating thicknesses up to 6mm can be achieved for efficient heat insulation.
Mainly used for corrosion protection. The electroless method of application ensures completely even deposits and no edge build-up. Typical coating thickness of 12 microns is standard, but precise coating thicknesses can be specified. We utilise high phosphorous Electroless Nickel solutions that offer the best corrosion resistance with good hardness and the ability to age harden if required.
Metal Teflon Composite
MTC coating is essentially an electroless nickel coating with a composite top coat that contains up to 25% Teflon/PTFE particles in the layer. In its use relating to plastic moulding, this assists in plastic release and flow for complicated mould designs incorporating lots of ribs and sections.
Galvanic Paint System
In applications where corrosion protection is required but conventional zinc coatings are excluded. Special paint products imparting galvanic protection and extreme corrosion resistance are possible. Corrosion resistance in excess of 1000 hours salt spray testing. These coatings can also withstand substantial flex and yield in the underlying base material and still remain well bonded. If the coatings are breached, the galvanic protection provides corrosion protection to the exposed material which prevents further corrosion.
