About
Laser Engraving Coated Metal
There are many different types of coated metal, with the appropriate type of coating dependent on what the metal will be used for. Different coatings offer different levels of protection, and choosing the right metal coating will make a vast difference in the appearance and durability of the product. Let’s take a look at the properties of coated metal, what it can be used for and why laser engraving coated metal is the way forward…
ENHANCED CHARACTERISTICS
Properties of Coated Metal
Coated metal combines the strength of metal with the enhanced characteristics provided by its coating, of which there are many types. Depending on what the metal will be used for, the coating can be applied through a range of methods, whether this is electroplating, anodising, painting or powder coating.
Increased Protection
By coating metal, you can protect it from corrosion, wear and environmental damage. This can significantly extend its lifespan.
Improved Performance
Metals can be tailored to a particular application by employing different coatings, for example by coating metal in certain materials you can improve thermal resistance or its electrical conductivity.
Sleeker Aesthetics
Depending on the type of coating used, coating metal can achieve a range of colours and finishes on the base material. This can improve its overall appearance and create different textures.
A Uniform Finish
The coating process on metals ensures a smooth, uniform finish which provides the perfect base for laser engraving.
ACROSS INDUSTRIES
Typical Uses of Coated Metal
Manufacturers use coatings to finish and protect the surface of their metal parts, they may paint or spray the surface or use other methods such as anodising or electroplating to achieve their needs. Let’s take a look at some of the industries utilising coated metal…
Automotive Industry
Coated metals are widely used in the automotive industry because they resist corrosion, are durable and have an aesthetic appeal. You’ll find coated metals are used for parts such as wheels, trims and body panels.
Construction
Coated metals are a crucial component in the construction industry for everything from roofing and cladding to structural components. Not only are these coated metals essential to infrastructure, they can vastly improve appearance. In addition to protecting infrastructure from corrosion, these coated metals provide a strong surface that is resilient to abrasion and chemical stress.
Aerospace
The aerospace industry utilises electroplating to allow aircrafts to withstand extreme temperatures and prevent corrosion, which is particularly important in this field as corrosion can penetrate the metals and weaken their structural integrity.
Consumer Goods
There are many consumer products that benefit from coated metals, such as kitchen appliances, outdoor furniture, tools and everyday accessories. This can improve durability of these items and increase their aesthetic appeal.
Versatile
Applications of Laser Engraved Coated Metal
Laser engraving coated metal is achieved when the laser beam is used to either modify or entirely remove the coating and exposes the metal underneath. This creates a clear, contrasting mark that stands the test of time.
Industrial Marking
Traceability is a fundamental part of production in many industries from automotive to aerospace. Laser engraving can provide permanent, legible marks such as QR codes and serial numbers on a range coated metal parts. This is integral to the correct functioning of the manufacturing process and essential to inventory management.
Trophies and Awards
Trophies and awards made from coated metal can be personalised quickly and efficiently using laser engraving technology.
Signage
Coated metal is often used for signage because of its durability and weather resistance. The best way to engrave or mark these signs is by using a laser engraving machine which provides a durable mark that’s suitable for both indoor and outdoor use.
Branding
Companies can use laser engraving technology to add their logo across a wide range of coated metal products, making it quick and easy to produce long-lasting and effective marketing collateral.
