Facts You Must Know about Metal Chemical Etching

If you want to know about metal chemical etching, then this article is for you. Metal chemical etching is very useful in making high precision metal parts. Another good thing about chemical etching is that it is a very accurate process. It is also known as photo etching. In this article, you will get more information about metal chemical etching. So without wasting any time let’s jump into the main deal.

What is Metal Chemical Etching?

In simple words, you can say that it is a subtractive metal manufacturing process in which different etching chemicals are used to make highly accurate and complex metal parts. There are also other techniques like EDM, CNC, stamping, but chemical etching is one of the most effective techniques that provide high accuracy. It also takes less time in comparison to others and it also gives more flexibility in designing.

Another great thing about chemical etching is that it is a cost-effective option and deburring is also not needed. So after this, it’s time to talk about how the chemical etching process works.

How Does Chemical Etching Work?

There are some steps that are followed in chemical etching and to understand how chemical etching works, you have to understand all these steps. It is kinda series of different steps and it is important to follow them to get the best results. So down below you will get a briefly detailed list of all the steps, the number one step is:

1- Cleaning

In this cleaning process, all the preparation is done, this includes removing all the dirt, oils, grease, and residue from the metal surface that is going to be etched. This process is very important because if the metal surface is contaminated, then it causes defects.

2- Laminating

In the laminating process, dry film photoresist is applied to the metal surface and this is why the cleaning process is important. The reason behind applying the photoresist is that it will protect the area that won’t be etched.

3- Exposure

Now two masks are used that are generally made of glass or mylar and then the material is guided between them. After that through the masks, UV rays are shined from every direction results in crosslinking the film where the light was not blocked.

4- Developing

Now the material gets developed and the non-crosslinked films get dissolved in the developing process and the final product to be etched is ready.

5- Etching

Now the etching process takes place and the etchant is sprayed on the finished product from bottom to top, and then the unprotected metal gets dissolved and the final product is achieved.

6- Stripping, Rinsing, and Drying

Now in the stripping process, another chemical is used to remove the film and after that to remove all the remaining residue from the final product, the rinsing and drying process is used.


Chemical etching is a very popular method because there are a lot of advantages to using this method. Most of the information regarding metal chemical etching is mentioned above. Hope this article will clear your queries and doubts regarding it.

Warehouse Cooling

The temperatures in your warehouse tend to get very high and it has led to losses of inventory. You have tried using fans but they don’t make much of a difference – they only cool items that are closest to them. What can you do make sure that temperatures inside your warehouse are controlled at all times? It may be time for you to start thinking about installing warehouse cooling systems.
Many business people are reluctant to install these sorts of systems in warehouses because they don’t own them, and they figure that it is the responsibility of the owner of the building to make the necessary installations. Here is what you should take into account: your landlord is going to be reluctant to install anything he doesn’t have to and even if he eventually gets to it many months will have passed by, and all the while you will be losing inventory.
Landlords, however, are not opposed to tenants making such installations and then slowly recouping their expenses from the rent. You should talk to your landlord about bringing a warehouse cooling expert in to make an assessment and give you recommendations. If you agree that the cost of the cooling system is fair you can go ahead with the installation and then pay less rent for the coming months to make up for the money that you spent. You landlord will be agreeable because the cooling system increases the value of his property.
It is important to make sure that you get a high quality system installed so make sure you look for companies that deal specifically with cooling for warehouses. One such company is the Cambridge Renewable Energy Centre. They have a variety of cooling systems available and they are experts at installation and maintenance.

3 Benefits To Using A Monobloc Air Source Heat Pump

When it comes to heating your home, you have several options. However, these options are not all created equal. Choosing the right heating source may not seem like something that is at the top of your priority list. Most people heat their homes just fine using standard methods and using ones that are most common in their area. The problem with this is that they end up inadequately heating their homes and racking up insane electric bills. For this reason, it is recommended that you use a monobloc air source heat pump. There are many benefits to using this type of heating. Below is a list of three benefits to using an air source heat pump.
Benefits of Using A Air Source Heat Pump
Environmentally Friendly
Massive Reduction In Electric Bill
Easy Installation and Maintenance
Environmentally Friendly
One of the biggest benefits of using a monobloc air source heat pump is just how eco-friendly they are. They use heat that is extracted from cold air to heat your home. Because of this, there are little to no carbon emissions are given off. This is the only type of heat pump that can easily heat your entire house without having an environmental footprint.
Massive Reduction In Electric Bill
For those who do not care about being eco-friendly, you can at least care about your electric bill. Everyone is looking to save money and this is one of the absolute best ways. Over the course of time, you can save tens of thousands of dollars just by switching to a monobloc air source heat pump.
Easy Installation and Maintenance
The first question that most people have when it comes to this is about how easy it’s going to be to install and maintain. These types of heat pumps rarely break down and need maintenance. This is a huge benefit to those who are not well-versed in handyman work.

Metal Etcher

You are just starting a small manufacturing business and are in the market for a metal etcher – which kind should you choose? There are two kinds of metal etchers – those who use hard tooling to create parts and those who use photo etching. Those who do photo etching are much better than those who do hard tooling for several reasons.

The first is that hard tooling tends to compromise the metal sheet. The process requires the use of heavy tools and lots of force which can lead to cracks and tears. Any parts made from such metal sheets can be easily compromised, affecting quality of production and even leading to serious accidents.

The other benefit of metal etching is that it is faster than hard tooling. With just a few simple steps you will get parts ready to go. The metal is cleaned before the etching is done so that once the process is complete the parts are ready for use. Parts produced this way do not have burrs so there is no time wasted de-burring them.

Photo etching is also the way to get the most precise parts as it is highly accurate. Even with highly complicated parts design you will be able to get parts that are only +/-.01 mm from the actual measurements. This process can be used to produce one piece or millions which makes it ideal for small businesses as they don’t have to etch parts that they don’t need. The process is also highly affordable – you don’t have to worry about paying lots of money to get your machinery going.

To conclude, you are better off with a metal etcher who uses photo etching such as Qualitetch. They have been etching metal for more than 25 years so you can trust that they will do an excellent job.
