Steel is one of the most popular metal materials to use in manufacturing.
Thanks to the many useful properties it possesses. Here at Qualitetch, we utilise a number of steel variants, including both mild steel and carbon steel, to harness the durability and resilience of the metal.
Etched steel parts and components are great for a multitude of industries and sectors, including automotive, aerospace, electronics and telecommunications, and can be found in everyday items and objects in the home, on the road and in the workplace.
Mild steel is also known as carbon steel, spring steel and includes brand names such as Sandvik steel and Uddeholm.
Thanks to the incredibly accurate results and speed of the process used, we can offer our customers a range of commercial products with a low margin of error and high turnaround on orders. Please contact us today on 01354 658787 to find out more.
Our assembly line approach reduces manufacturing time and allows us to save time by cutting unnecessary steps out of the manufacturing process.
We have a dedicated team of fully qualified professionals who are on hand to deal with and complete assembly work requests from our customers.
We offer assembly, soldering and spot welding, bespoke packaging, and also many other specialist bespoke customer requirements that our clients may have.
Photo Etching Process
The photo etching process produces metal components that are both stress-free and burr-free compared to more traditional manufacturing methods – ensuring that your end product is as both accurate and precise to your drawings.
Qualitetch offer a huge range of metals for etching including: Stainless Steels, Carbon Spring Steels, Copper, Brass, Nickel Silver, Mild steel, Phosphor Bronze, Silver, Beryllium Copper, Aluminium, Nickel, Mu Metal, Alloy 42, Alloy 52 & Many Others.
Metal Cleaning Process
In order to ensure perfect parts every time, we need to clean the sheet metal to remove any impurities from the sheets surface before manufacturing your designs. This involves passing the metal sheets slowly through acid or alkaline solutions and rinsed prior to laminating, printing and developing.
Metal cleaning involves passing the sheets slowly through conveyorised acid or alkaline solutions and rinsed clean prior to the lamination, printing and developing stages, depending on the sheet metal choice required.
Preparation - Lamination
Once cleaned the metal sheets are coated with a UV sensitive photo resist, which melts to sheet in preparation for the printing process.
Preparation - Printing
The printing process involves us taking your chosen profile design and applying it to a two sided top and bottom acetate photo film mask, that we then print your design onto the UV sensitive photo resist.
Preparation - Developing
Once the metal sheet is printed with your chosen design, we then need to develop the sheet. This process effectively washes away the fine lines of the profile we are cutting, leaving raw metal track lines ready for the etching process to work it's magic very precisely.
Photo Chemical Etching
The etching process itself is an acid, usually ferric chloride, that effectively eats it's way through the metal at a known rate to ensure precision and targeted only in the areas you wish to remove, such as the profile track lines or other holes and features such a mesh. The rest of the sheet is masked by the UV photo sensitive blue resist, to protect the metal from the etchant until the parts are complete. This can be a very useful in a manufacturing process as the design can be very complex or include tabs or half etch fold bend lines at no added cost as you simply print your design rather than needing expensive machining time. Following an on-line dimensional check, all that is then required, is for us to strip and remove the UV photo sensitive resist coating and the parts are ready for full QA Inspection.
At Qualitetch we offer various levels of QA inspection depending on our customers needs, as we supply both major blue chip businesses all over the world as well as smaller local businesses and anywhere in-between, as the photo etching process is very versatile. We have various automated optical equipment to ensure you parts are accurately supplied to your drawings. We also offer levels of inspection including 100% inspection, PPAP levels, batch inspection, First article inspection (FAIR) and bespoke customer inspection as required.
Once the parts are fully inspected and passed they are ready to be packed and sent to the customer, or for additional processes such as plating, forming, soldering, spot-welding, machining, EDM wire erosion, heat treatment or any other bespoke services required, such as assembly.
The Etching Process
This process is highly accurate and cost effective, with high definition results every time. Photo etched steel retains all existing properties thanks to this process, which leaves the metal both burr- and stress-free.
Once the design has been finalised, we can then produce a profile artwork film to print the image onto the metal sheets UV resist. After developing the sheets are then passed through a chemical bath using an etchant: ferric chloride.
The finished parts are then cleaned and dried, removing any trace of photo-resist and chemicals, before being approved dimensionally by our skilled technicians using the latest automated inspection equipment. Parts and components can then be plated or finished to prevent corrosion and rust or simply for decorative effect.

Chemically etching molybdenum is ideal for use in many industry sectors including the medical, aerospace, defence, marine and telecommunications industries, due to it’s ductility and high corrosion resistant properties, and has one of the highest melting points of all the pure elements.
