Molybdenum is a diverse material used across manufacturing industries
Molybdenum is a material popular in the manufacturing industry thanks to its many uses and benefits it holds.
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, and photo etching is an easy way to manufacture sheet Molybdenum.
Chemical etching with molybdenum or with one of it's nickel based alloy derivatives such as Hastelloy, is useful because of the metal’s high melting point and low propensity for thermal expansion. This makes it perfectly suited for parts that encounter particularly high temperatures.
Here at Qualitetch, we have the capacity to chemically etch and machine components using molybdenum to reach customer’s specific requirements.
Molybdenum is an incredibly versatile metal to work with, allowing us to engage in molybdenum etching for components of a large variety of sizes, from thick to thin.
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.
Photo etching is not only a great way to manufacture components. Our chemically etched molybdenum parts are all completed and finished to the highest quality, meaning that you won’t be left with burrs, rough edges, or heat-affected damage on the metal.
Qualitetch has over 30 years of experience in photo chemical etching. This means that you can be assured your components are left in the safe hands of our experienced engineers; affording every individual part the same high level of care and attention to detail.
