Information about the different finishes available for Technifast products only Datasheets Material Specifications Pin Economics Plating & Finishing Recommended Hole Sizes Shear Strengths Standards Tolerances PLATING & FINISHING Technifast can manufacture precision fasteners and components such as pins, dowels, spacers, inserts and engineers keys with a range of coatings, plating and finishes. Depending on the application, components can be plated to improve resistance to corrosion, provide a uniformed surface or made decorative. Read on to discover some of the coating techniques used on precision engineered parts. We work with respected and established plating and finishing partners to provide a high-quality service, which we offer as part of our manufacturing service. ** Please note, these services are outsourced and can only be offered in conjunction with parts supplied by Technifast ** Zinc Plating Zinc plating is a process which is well-suited to hardened steel base materials. It provides a very bright finish and usually incorporates a clear chromate treatment to increase corrosion resistance. Zinc plating is an established technique for small, precision engineered fasteners. Due to the continued and unpredictable risk of failure, customers should be aware of the risk of subjecting high tensile fasteners to an electrolytic process, and to avoid this risk wherever possible. The responsibility for assessing whether electro-zinc plated high tensile fasteners should be used in a particular application remains with the end-user, in liaison with the design authority. Nickel Plating Nickel plating is a cost-effective and commonly recognised technique in the manufacture of specialist components. It is used to improve the hardness of the base material, whilst making it more resistant to both wear and corrosion. Zinc Nickel Plating Zinc Nickel plating is one of the most popular plating methods, providing a finish which is suitable for steel and brass components. It is widely used in the fastener industry to offer improved protection from corrosion and as a more environmentally-friendly alternative to cadmium plating. Electroless Nickel Plating This is a very common form of electroless coating. An electroless nickel finish offers outstanding corrosion protection combined with a natural lubricity. This results in a surface finish that is uniform across the high-precision components that Technifast manufacture and supply. Stainless Steel Passivation A stainless steel base material is naturally resistant to corrosion. However, stainless steel is not completely unaffected by rust, and the passivation process can improve the resilience to oxidisation by eradicating the free iron from the stainless steel to further help protect against corrosion. Decorative Chrome Plating This is a technique that can also be referred to as nickel-chrome plating and is used to give an attractive finish to a variety of applications. It is popular for components which will be ‘on show’, but it is also hard wearing and stain resistant. Geomet® 500 Coating Geomet® 500 was formed specifically with integral lubricant for coating fasteners, to assist in assembly and to give a consistent tightening performance. Fasteners coated with Geomet® 500 have a silver/grey metallic appearance. They are also electrically conductive, making them a suitable choice for most applications.
