These days, there are plenty of etching processes to choose from. However, chemical etching is one of the oldest techniques that have been developed. In fact, decorating a medieval armor usually makes use of chemical etching. Nowadays, chemical etching has improved tremendously. With new methods and chemical solutions, results are more elaborate and accurate.

So, how does chemical etching work? In this article, you’ll learn more about this specific subject.

Chemical Etching Explained

There are different techniques for chemical etching. Having said that, most methods would generally include:

* Cleaning

* Laminating

* Exposing

* Developing

* Etching

* Stripping

Generally, the process starts with a light-sensitive laminated layer that’s introduced to the material that you want to etch. The material that you wish to etch is also known as the substrate.

The substrate and light-sensitive laminated layer are then exposed to an ultraviolet light together with the negative. The ultraviolet light will then “harden” this light-sensitive layer. However, because of the negative, there will be areas of the light-sensitive layer that can be washed away as it didn’t “harden” during the UV light exposure. The washing away of the laminated layer is also known as the Development step.

The next step is to introduce an etching chemical. Keep in mind that there are parts of the material that is protected by a light-sensitive laminated material. Thus, the etching solution will only eat through the parts that are unprotected.

After the etching process is done, the next step is to strip off the remaining hardened light-sensitive laminated layer. At this point, the etching process is mostly done.

Why Chemical Etching?

Chemical etching is an excellent choice if you want to create high-precision, multi-layer, and complex metal parts. The tolerance of the etching process is usually +/- 10%. For example, when you chemically etch a specific part that’s 100 μm, you can expect a deviation of up to 10 μm. Also, chemical etching is highly advisable if you want something with profiled edges, sharp edges, and round holes.

Another desirable feature of chemical etching is its flexibility in terms of scalability. You can start creating a prototype from drawings in just a matter of days at a relatively affordable cost. Also, converting to large-scale production is rapid and affordable as it does not require expensive equipment found in other etching methods.

What Materials Can Be Etched

Chemical etching can be used for a wide variety of materials. The method especially shines for metals. This is because almost all types of metals can be etched chemically.

For the most part, you can use chemical etching for:

* Steels

* Aluminum

* Nickel Alloys

* Copper

* Brass

Wrapping It All Up

Chemical etching is a process of using an etching solution to turn your drawing into a real-life prototype. The substrate is coated with a light-sensitive laminated layer and together with the negative, it is then exposed to UV light. The laminated layer will serve as a protection against the etching solution.

When the etching solution is applied, it will start eating through the substrate except for the laminated parts. The last step of the etching process is stripping away the remaining laminated part.

Etching will always have a place despite the many newer methods as its cost-efficient, flexible, and accurate.

Sheet Metal Etching is a chemical process which has many steps. It may have variation by types too. Metal can be formed thick, thin, plate shaped by Industrial process. This kind of metal is called sheet metal. This thickness, size and shape can be customised by choices. Etching is a traditional process. It involves strong acid and metal cut as an etching design in the metal. The metals like zinc, copper, steel are used in etching of sheet metal as this metals are acid resistant.

There are also some metals like:

Steel and stainless alloysTitanium and titanium alloysCopper and Copper alloysmolybdenum and polyamides

The acids which are generally used in sheet etching:

Ferric chloride and mixture of hydrochloric acidNitric acid and water solution in 1:3 ratioCopper Sulfate

The type of sheet metal etching:

Wet etching : When a material dissolves at the time of immersing.

Dry etching: Reactive ions or vapor etchant is needed to make the material dissolved.

Method of etching sheet metal:

Prepare the substrate by cleaning it. Then laminate it with a light-sensitive film. Fix your photo too on the top of the laminated material. This UV light passes through the vacant area of the photo tool.Then Create unique design of yours on non UV exposed area. Heat the substrate. Etch design using chemicals spray and high pressure.

It is impossible for human beings to thrive without the printing industry. A number of methods are utilized for creating different images from a hard surface, a metal plate, and also a flat surface in the world of print development at present. Several of these methods consist of etching and engraving. In this article, we will discuss the topic: what is the difference between etching and engraving?

What exactly is etching?

Etching is considered to be the art of producing an image using acid which helps to remove the mental unlike cutting the metallic surface using a tool. Most typically, a wax coating is used in the form of a ground that is resistant to the acids which are being used. Following this, the image is drawn through the wax by making use of a pointed metal. Next, acid is being applied carefully to the surface which is guided by the lines that have been drawn through the wax thus producing lines of various depths.

The line’s softness which results from the work done by the acid along with the simple needle strokes together produces an appearance resembling a drawing made by a fine pencil.

You’ll come across different types of etching at present including water etching, glass etching, laser etching, soft-ground etching, dry etching, gravure etching, sugar lift etching, and so on.

What exactly is engraving?

Engraving is actually a printmaking process where a sharp plus pointed tool is being used by the artist (known as burin) for cutting lines into a metallic surface and this process is referred to as incising. Following this, the metallic plate is going to be inked and the ink will be forced into the grooves made with the help of the burin and then the plate is going to be pressed. This procedure can be done with the help of the machine or manually and is primarily employed for making jewelry, guns, and silverware.

What is the difference between etching and engraving?

1. The nature of engraving and etching

Engraving is considered to be a printmaking process where a sharp plus pointed tool is being used for cutting lines into a metallic surface. On the other hand, etching is considered to be the process of making an image using acid which is used to remove the metal.

1. Physical effort required

Less physical effort is required for performing etching since the design is been drawn by the etcher through the wax. On the contrary, more physical labor will be required for engraving since a tool is being used for cutting into the metal.

1. Object size

While engraving is usually used for large materials, etching is appropriate for thin materials and smaller projects.

1. Materials used

While engraving can be used for any material such as plastic, metal, wood, or stone, etching is appropriate for only the metallic surfaces.

Conclusion:

In spite of being used for almost the same purpose, the process of engraving and etching can be somewhat different. The method to select depends mainly on the availability of skill, the type of metal to be used, the preferable outcome plus the option of using either a chemical procedure or a physical process.

It is necessary to etch the thin films as a substrate to design a functional metal part on it. Normally, two types of etching processes are used to create such etched components, wet etching, and dry etching.

Wet etching

In this process, etched components can be created by immersing the masked substrate into a chemical solution to dissolve its unmasked part. It is the simplest and most cost-effective technology used for creating precision metal parts. You only need a container and etching chemical to etch the required material precisely by dissolving the material in the liquid solution. However, you will have to find a material that can be masked on the design of the metal part of your substrate so that its unmasked part can dissolve without dissolving the mask in the liquid chemical and etch the metal part precisely. Moreover, you will have to choose etching chemicals according to the type of material you want to etch.

When to use a wet etching process?

Wet etching can be the best method to etch substrates made of thin metal sheets or films. You can find various combinations of etching chemicals and masking materials to choose from as per your suitability. Though other etching processes like isotropic and anisotropic processes can also be used for etching substrates made of thin metal plates but there is a risk of undercutting or overcutting the layer of the mask which can be devastating for the idea creating precision etched components.

Dry etching

The technology of dry etching can further be divided into three categories- RIE or reactive ion etching, Sputter etching and vapor phase etching.

In RIE, several gasses are introduced in a reactor in which the substrate to be etched is placed. The mixture of gases is stricken by plasma by using the power of RF to break the molecules of gases into ions. These ions react with the surface of the substrate when accelerated to form another gas which can be used for reactive ion etching.The sputter etching is RIE without the reaction of ions. In sputter etching, these ions can etch the material to be etched without any chemical reaction if the energy of the ions is high enough.The equipment used for Vapor phase etching is simpler than the equipment used for RIE. The substrate to be etched is placed in this process in a chamber containing one or more gases to dissolve the substrate due to chemical reaction with the molecules of gas.

Such things make the process of dry etching very complicated as you have to adjust several parameters for balancing physical and chemical etching.

When to use a dry etching process?

Though dry etching is a costlier process than wet etching still you can use it to create etched components if you are worried about the resolution of the structure of thin film or you want deep etching in the vertical sidewalls of the substrate.

Thus you can use different etching methods to produce etched components according to your requirements and budget.

As an athlete in the early stages of training you have decided to keep track of your vitals. They are important – they tell you how well your body is doing and how it is adapting to the rigors that you are putting it through. One of the things that you want to monitor is your breathing. Breathing rate is important because it tells you not just how hard you are working your heart, but how hard you are working your muscles too. The harder you breathe the more oxygen you send to your muscles which translates into bigger and stronger musculature over time.
Keeping track of your breathing is not as easy as buying a device. You need to know how to collect the data so that over time you can form a picture that informs you about your health. When you shop for a device you should be looking for one that just monitor how many times you breathe in and out – it should show you overall body performance and improvement in a given period.
The best way to monitor your breathing is to do it both when you are active and inactive. You can start by wearing your device as you sleep so that you can see how many times you breathe in and out when you are at rest. You can then look at how you breathe when you go about regular tasks about the home, when you are shopping, when you are at work and so on. This data will provide a valuable baseline to compare with the breathing data that you collect when you are working out.
Equivital can provide you with one of the best breathe monitoring devices in the market. You can see what they have to offer on their website, http://www.equivital.com/.

It has taken you months to source the right air source heat pump for your Norfolk home and now that you have it you want to find an installer who will do a good job. There are many companies that advertise themselves as air source heat pump installers but when you look closely at the services that they offer you may find them lacking. No doubt your air source heat pump cost you quite a bit, so it only makes sense that you find an installer who can set it up and get it to work properly for years to come. Before you hire ask the following questions:
How long have you been in business? – this can be telling. A good installer will likely have been in business for at least 10 years. They will have done many jobs in that time that will furnish them with the necessary expertise to handle many different kinds of air source heat pump systems.
Do you have an office that I can visit? – today, when so many services can be found on the internet homeowners sometimes hire installers without finding out whether they have an actual office that they can visit. It is only when things go wrong that they discover that they have no way of tracking down the installer. Before you hire anyone to work in your home make sure you know where their office it – be wary of those who move locations often as they could be running from something.
What happens if you are not able to do my installation properly? – it is important to get the answer to this question in writing. Installations go wrong and if it happens to you you would like the problem to be fixed or to get your money back.
