New series of high-performance heat sinks especially designed for the dissipation of heat in electronic systems using forced air. A heat sink is a device which carries heat from an object and dissipates it to a surrounding fluid medium (such as air) with the help of fins (to increase surface area in contact with fluid). It does this continuously so that the object being cooled is able to function properly. We manufacture both Forced Convection and Natural Convection driven heat sinks. Wattage dissipation of these heatsinks ranges from 10W to 10, 000W depending on the requirement and size constraints. Each heat sinks designed by us is tailor-made to suit the particular needs and preferences of each customer. We create an optimum product of high quality, performance and efficiency. Applications: Power Supply for Inverters for traction telecom and more

Zinc chromate, ZnCrO4, is a chemical compound containing the chromate anion, appearing as an odorless yellow powder or yellow-green crystals, but, when used for coatings, pigments are often added. It is used industrially in chromate conversion coatings, having been developed by the Ford Motor Company in the 1920s.

Chromate Conversion Coating (also commonly referred to as Chemical Film, Chem Film, Alodine or Iridite) converts the surface properties of the substrate (typically aluminum or magnesium) as compared to plating which applies a coating onto the surface of the substrate. Chromate provides excellent corrosion resistance, is conductive and results in no measurable buildup (0.00001â- 0.00003â) on the parts. Chromate conversion coatings are the most widely used coating for corrosion protection of Aluminum and Aluminum alloys minimizing surface oxidation. It is commonly used for an undercoat for paint or adhesive applications due to the excellent bonding properties it provides. Class 1A coatings give maximum corrosion protection with the highest electrical surface resistance while class 3 coatings have lower corrosion protection and provide lower electrical surface resistance. We apply both standard hexavalent (clear and yellow) and RoHS compliant Trivalent (TCP) to Aluminum Alloys.

ALUMINUM ALLOYS can be machined rapidly and economically. Because of their complex metallurgical structure, their machining characteristics are superior to those of pure aluminum. The microconstituents present in aluminum alloys have important effects on machining characteristics. Nonabrasive constituents have a beneficial effect, and insoluble abrasive constituents exert a detrimental effect on tool life and surface quality. Constituents that are insoluble but soft and nonabrasive are beneficial because they assist in chip breakage; such constituents are purposely added in formulating high strength free-cutting alloys for processing in high-speed automatic bar and chucking machines.

Stainless steel does not rust or corrode with moisture like regular steel can. Depending on the environment, stainless steel offers a large variety of grades and surface finishes that make the parts ideal for many applications. When your part requires steel and corrosion resistance, stainless steel is the perfect material. Compared to other machining materials such as brass, stainless steel can be very challenging to machine. However, this doesnt mean that you have to put up with delays and inconsistencies. Some machining companies have a problem overcoming the challenges to provide a constant stream of components. With us, no such issue exists because we have an extensive knowledge of CNC machining. Not only do we know about stainless steel machining, we also understand the various properties in the different metal alloys that can be found within the Stainless category.

Aluminium not only offers many advantages due to its material properties, it's also extensively adaptable to fabrication and machining processes. Generally, tooling costs are lower than with many other metals and the high speed at which certain processes can be completed, offer even greater labor cost savings. Many additional fabrication processes that would have to be carried out on other materials, can be designed into the extrusion process of aluminum.

A heat sink is designed to maximize its surface area in contact with the cooling medium surrounding it, such as air. Air velocity, choice of material, protrusion design and surface treatment are factors that affect the performance of a heat sink. Heat sink attachment methods and thermal interface materials also affect the die temperature of the integrated circuit. thermal adhesive or thermal grease improve the heat sink's performance by filling air gaps between the heat sink and the heat spreader on the device. A heat sink is usually made out of copper or aluminium. Copper is used because it has many desirable properties for thermally efficient and durable heat exchangers. First and foremost, copper is an excellent conductor of heat. This means that copper's high thermal conductivity allows heat to pass through it quickly. Aluminium heat sinks are used as a low-cost, lightweight alternative to copper heat sinks, and have a lower thermal conductivity than copper. We manufacture both in the highest qualities.

Aluminum alloys are anodized to increase corrosion resistance and to allow dyeing (coloring), improved lubrication, or improved adhesion. However, anodizing does not increase the strength of the aluminium object. The anodic layer is non-conductive.[3] When exposed to air at room temperature, or any other gas containing oxygen, pure aluminum self-passivates by forming a surface layer of amorphous aluminum oxide 2 to 3 nm thick, [4] which provides very effective protection against corrosion. Aluminum alloys typically form a thicker oxide layer, 5â15 nm thick, but tend to be more susceptible to corrosion. Aluminum alloy parts are anodized to greatly increase the thickness of this layer for corrosion resistance. The corrosion resistance of aluminum alloys is significantly decreased by certain alloying elements or impurities: copper, iron, and silicon, [5] so 2000-, 4000-, and 6000-series Al alloys tend to be most susceptible. Although anodizing produces a very regular and uniform coating, microscopic fissures in the coating can lead to corrosion. Further, the coating is susceptible to chemical dissolution in the presence of high- and low-pH chemistry, which results in stripping the coating and corrosion of the substrate. To combat this, various techniques have been developed either to reduce the number of fissures, to insert more chemically stable compounds into the oxide, or both. For instance, sulfuric-anodized articles are normally sealed, either through hydro-thermal sealing or precipitating sealing, to reduce porosity and interstitial pathways that allow corrosive ion exchange between the surface and the substrate. Precipitating seals enhance chemical stability but are less effective in eliminating ion exchange pathways. Most recently, new techniques to partially convert the amorphous oxide coating into more stable micro-crystalline compounds have been developed that have shown significant improvement based on shorter bond lengths.

We have various surface treatment capabilities for Aluminium. We can do Doerken coating, powder coating, painting, electroless nickel plating, yellow chromate, trivalent chromate, black anodising, blue anodising, clear anodising and hard anodising

Electroless Nickel Plating is the deposition of a nickel-phosphorous alloy onto a metal substrate without the use of an electrical current. The electroless nickel plating process utilizes an autocatalytic chemical reaction to deposit a reliable, repeatable coating of uniform thickness. This uniformity of deposit can, in some cases, eliminate the need for post-plate grinding. Electroless nickel demonstrates excellent corrosion protection, with similar lubricity properties to plated chromium. Electroless nickel effectively coats parts with sharp edges, deep recesses, seams, threads, and complex geometries. COMMON APPLICATIONS OF ELECTROLESS NICKEL COATINGS:Aerospace Components: For wear resistance, corrosion protection, chemical resistivity and lubricity on valves, pistons, engine shafts, engine mounts, compressor blades and other flight-critical components.Electrical Equipment: Due to solderability and conductivity properties.Packaging & Handling Machinery: Due to wear resistance, cleanliness and attractive finish.Chemical Manufacturing and Transport Equipment: Due to chemical resistance.Molds & Dies: Corrosion protection minimizes erosion and abrasion. Low coefficient of friction improves release.Food Service Equipment: For superior corrosion and wear resistance, attractive finish and cleanliness.Plastics Manufacturing Equipment: For durability and release properties on injection molds and extrusion dies.Oil & Gas Components: For corrosion protection in harsh undersea and underground environments for parts such as valves, pumps, pipe fittings and others.Printing Industry Equipment: For abrasion resistance on conveyance and chemical resistance on printer cylinders.Automotive Components: For wear protection and corrosion resistance on pistons, cylinders, gears, differential pinion ball shafts, fuel injectors, ball studs, transmission thrust washers, knuckle pins, hose couplings, heat sinks and others.
