Grinding/Lapping Grinding, also referred to as Lapping is a method of utilizing a grinding wheel as the cutting tool for the process of precision machining.
Tumbling The tumbling process is used to smoothen and polish rough surfaces. In this process, the target unit would be tumbled with plastic pellets or oilstones. Here, the sharp edges, machine and tool marks are removed and the defects in small sized components are eliminated to leave a smooth surface.
Polishing Polishing is the process involved in creating smooth and shiny surfaces on a project by utilizing specialized techniques such as rubbing or chemical action to deliver a significant specular reflection. Our services also cover polishing of some plastic such as PMMA to obtain transparency.
Anodizing Our Anodizing options are mainly for aluminium anodizing. Our experts use this process to perform an electrolytic passivation process that creates and AL203 film that can serve protective or decorative purposes on your project. Anodizing can also improve the electrical insulation performance, hardness and corrosion resistance of your project.
Hard Coat Anodizing This process is similar to the anodizing. Hard coat anodizing uses a thicker anodizing thickness to enhance the properties of wear resistance, corrosion resistance and electrical insulation performance of your project.
Chromate Conversion Coating The Aluminium chromate conversion process is directed at improving the corrosion resistance of wrought, heat-treatable and cast aluminium alloys and also provides an excellent base for subsequent painting or powder-coating services.Alodine The "Alodine" is an international brand name used to describe the Henkel Adhesive Technologies conversion,
anodizing and functional coatings that are applicable for use on Aluminium, Magnesium and a host of other non-ferrous alloys. Alodine coatings are excellent for providing improved protection against corrosion and easing paint adhesion on light metals and their alloys. The film can also be conductive.
Black Oxide/ Blackening The blackening process utilizes black oxide to deliver enhanced rust protection. The process works by creating a conversion coating that works to isolate the air and protect your project.
Passivation Our passivation process is one of the best available in the industry. We use high quality passivation methods to add a light coat of protective material, such as a metal oxide, to provide a shell against corrosion on your project.
E-Coat/ ED-Electrophoresis Deposition E-coating is a specialized system of painting that utilizes electric current to deposit the desired paint and coating on the project. The aim here is to generate a uniform and smooth coating, thereby increasing the hardness and impact resistance.
Teflon Electroless Nickel Plating Teflon is usually applied for its excellent self-lubricating properties that it can convey to the applied parts. This type of coating is excellent for providing low-friction values on parts. It is especially very effective where two parts are sliding together such as tools, dies, cylinders, molds, gun parts, bearings and co.
Zinc Plated/ Galvanization Zinc plating or Galvanization applies a protective zinc coating to iron or steel materials. This is the most common type of coating. It is also the most cost-effective method to prevent rusting.
Nickel Plating/ Electroless Nickel plating The Nickel plating technique involves the addition of a nickel coat to a plastic or metal by using either an electrolytic method or auto-catalytic chemical technique.
Chrome Plating Chrome plating is a specialized technique of plating that electroplates a thin layer of chromium onto a metal object. The electroplated chromed layer can serve decorative purposes or provide other functional value such as increased corrosion resistance, ease of cleaning and surface hardness.
Tin Plated Tin-plating can be applied to a wide array of base metals. From steel to iron and copper, many metals can be coated with a thin layer of tin. Tin-plating enhances the appearance of these materials and promotes their suitability for certain applications. This process can also deliver an improvement in performance and durability.
Copper plating Copper plating is generally employed as a primer prior to the application of other metal plating. Copper is a good conductive material, copper plating will also improve the appearance of the later plating when applied as a primer.
Silver Plating Silver has good heat and electrical conductivity. It also boasts of a laudable reflector capacity. Silver plating is a great type of plating generally suitable for components that are to be used in the manufacturing industries such as electrical, lighting appliances and other instruments.
Painting At First Part, we offer different types of painting services with an extensive option of paint types. You can get spray painting, aerosol painting or any other type of painting for your project, delivered to perfection to leave a smooth and evenly-coated surface. We also offer primer painting that is generally prior to the main painting. Our painting services can be applied to both plastic and metal projects.
Powder Coating Powder coating involves the application of dry powder to the project by electrostatic adsorption. The coating then settles and becomes perfected on drying.
Silk screen Silk printing is a printing technique applied by utilizing a mesh to transfer ink onto the substrate. This type of printing is popularly applied for patterning or logo printing.
Pad Printing Our Pad printing technique is a special printing used for on otherwise difficult products and projects across many industries. The procedure involves the transfer of an image from the pattern from a silicone pad onto a substrate with the aid of an indirect offset printing process. Pad printing can be applied to medical and automotive industries, serving promotional, apparels, electronic objects, appliances, toys and sport equipment.
Etching Etching is one of the more traditional processes of branding and after treatment. At First part, we provide excellent etching processes that uses strong acids or mordant to cut into metal surfaces and create an inscription or design in intaglio in the metal.
Laser Etching The Laser etching process is a specialized etching process that uses a laser beam to cut an image or pattern into a part. This process is permanent.
Electro-polishing Our electro polishing technique is an electrochemical process aimed at polishing, passivating and deburring metal units for a more desirable output.
Vapor Polishing Vapor polishing involves the application of a chemical to the surface of plastic (generally PC) to change the finish of the plastic to water clear or high gloss.
Nitriding/QPQ Nitriding is a heat-treatment process that is used to diffuse nitrogen into the surface of a metal to make a case-hardened surface. The process is mostly used when dealing with low-carbon and low-alloy steels.
Tinting The tinting process simply involves the addition of a desired colour to a PMMA substance.
Heat Treatment We deliver top-tier heat treatment services that allows you to use high temperatures and heating or low temperature cooling to obtain desired microstructure and other properties in your metal.
