The Difference Between Etching And Engraving

Etching and engraving are used interchangeably though there are important distinctions which is between them. Major difference between etching and engraving is a depth of a mark. Then what’s the difference between etching and engraving? Engraving is the computer generated process that has the beam of light which basically drills into a product in a way to remove top layer. You may discover that with engraving, surface is very rough to touch where the design may appear uneven. However, etching is the manual process that use the film stencil that can develop the required image together with the area which etched is got sand blasted. Etching result at the same time as more manual giving you softer and clearer satin finish. It is know that etching is 100% permanent and this won’t come off an item. The image of the engraving is designed and also the design of etching can be seen with a visual difference.

Etching, and engraving have the marking that have different applications which can be used together with different materials. Engraving is effectively on almost various material of the choice that include metals, wood, plastics, leather, glass, soft materials such as paper, and acrylic. Etching affects the materials surface, enhancing contract and altering reflective. The best material to use for the etching are anodized or bare aluminum, stainless steel, plated metals, ceramics and polymers. Etching is widely used throughout the industry to make permanent marking without destroying the materials. It can also be used to form UID codes, bar codes, logos, and QR codes, for different products.

Engraving creates the cone-shaped indentation in a chosen material with the help of the high-powered laser. Deep cut is around 0.020″ to 0.125″, but the deeper engravings will be attained by passing a laser on similar place for some times. Engraving is best for the parts which experience tear and wear, but not all parts which are critical for the safety. Engraving is the best for keepsake items and also personalizing gifts, and may be used with different materials.

Etching creates the shallow markings which is about 0.001″ through the help of high-powered laser that make the surface layer to melt using the chosen material. It is the best for the low-wear applications because the shallow markings have the tendency of fading easily with time. The hard materials like anodized, plate or bare metal surfaces are actually the best materials to be used in the etching applications.

Chemi ETCH

The uplifting news for craftsmen who are keen on making the cold look of etched glass is that the procedure currently takes around 3 minutes of time. The six stage process starts with the utilization of glass etching cream. The procedure isn’t just simple it is sheltered. The outcomes are treasures that will be cherished by your family for a considerable length of time. The best part is this procedure fits effectively into any home interest.

If you don’t mind remember that etching is lasting, and the treatment won’t wear off, or be evacuated. The etching turns out to be a piece of the glass itself. The advantage is that specialists can figure out how to add concealing to their undertakings.

The impact of etching can be accomplished in three different ways. Sand impacting, laser etching and chemical etching. In this article, we talk about how to utilize chemicals to deliver etching on glass. Laser etching is costly and requires uncommon hardware. Sand Blasting is utilized on heavier evaluation glass and makes a wreck. It isn’t extremely command post inviting. For the locally situated craftsman that leaves chemical etching.


It is significant that each venture start with wellbeing. Wellbeing for yourself, and your youngsters. Make certain to adhere to the directions that are illustrated by the producer.

Supplies Needed:

Covering Tape

Build up Free Cheese Cloth

Cotton Buds

Latex Gloves


Paper Towels

Defensive Goggles

Apparel that is long sleeved.

Stage 1: Preparing the Glass:

The initial step is to clean the glass. The glass must be as perfect as could be expected under the circumstances. Glass cleaner that is Finger Print Resistant ought to be maintained a strategic distance from. It delivers a film on the glass that avoids that etching cream from etching. Ensure that once the glass is spotless it is additionally liberated from fingerprints and smirches The glass must be totally dry before continuing to the subsequent stage.

Stage 2: Creating the Design:

Utilizing care, cut the stencil and the support sheet to estimate utilizing a couple of scissors. Cutting the two sheets simultaneously keeps your fingerprints from getting onto the rear of the stencil. Fingerprints can upset the chemical procedure and cause the etching to be of low quality.

When the site for the etching is found, evacuate the sponsorship paper and apply the blue stencil to the outside of the glass so the clingy surface is in contact with the glass. Utilizing veiling tape you can solidly connect the stencil set up.

Cautiously move the stencil to the glass by scouring a wood create stick over the stencil. Use alert with the goal that the stick doesn’t tear the stencil. You will realize that you are doing this effectively on the grounds that the shade of the paper will change from dull blue to a lighter shade of blue.

Stage 3: Removal of the Carrier Sheet:

When the shade of the stencil has gone to a uniform light blue, you can expel the unmistakable plastic transporter sheet. To do this, cautiously evacuate a segment of veiling tape and afterward, lift up one corner of the stencil. In the event that the stencil didn’t totally move essentially supplant the blue sheet and transporter sheet and rub the stencil back onto the glass with your wooden specialty stick.

Stage 4: Protecting Clear zones with Tape:

Any segment of the glass around the stencil that you would prefer not to unintentionally become etched should be secured with covering tape. Start by first taping around the edge of your structure and afterward work outward to cover any spots that you need secured. At the point when you get to a zone where you should cover the tape at that point do as such by leaving a 2-3mm cover.

To guarantee that the tape is immovably clung to the outside of the glass utilize the iced back up sheet to press tenderly over the tape and stencil region. You can hold the article up to a light source to check if there are any little openings in the tape. In the event that you find that there are gaps, just spread them over with tape, and rehash this progression to ensure that new tape is solidly appended. The objective is to keep any etching cream from leaking under the edges of the tape. TIP: Do make an effort not to expel the tape as it will make the structure tear.

Stage 5: Using the Armor Etching Cream:

Kindly read the producers guidelines. You will see a helpful hint in the directions. Room temperature is best at 22C. When your article is appropriately taped, you are prepared to apply the Armor Etching Cream. To start, shake the holder to guarantee that substance are all around blended. Wear your wellbeing latex gloves and goggles. Spot the article to be etched over paper or cardboard. NOTE: you are working with a corrosive, so ensure that you are close to enough to a water source to wash any corrosive off your skin on the off chance that you should come into contact with the corrosive. NEVER WORK WITH ACID WITHOUT GOGGLES.

The etching cream must be applied in a thick layer. The objective is that once the cream is applied, you can’t see the through it, to the plan. Apply the cream cautiously guaranteeing that it remains inside the taped off region.

Stage 6: Finishing up the Project:

Keep on wearing your Goggles and gloves. When the etching cream has been on the article for a moment, turn on the tap and alter the water temperature to luke warm. Recall the etching cream just needs to remain on the glass for one moment. When that moment is up, tenderly flush off the etching cream under the tap. When the entirety of the etching cream has been evacuated, you can expel the tape and stencil.

The last advance is again to clean the glass utilizing class cleaner and dry totally.


The craft of glass etching has a rich, and a profound history that utilization masterful aptitude in mix with a hand-made method. There are numerous utilization for glass etching that incorporate items made out of precious stone, glass marble and even stone.

A Brief Intro to Chemical Etching

What exactly is chemical etching?

Chemical etching also referred to as “chemical milling” or “industrial etching”, happens to be a subtractive procedure in manufacturing. The process involves the spraying or immersion of metals using temperature-regulated chemical substances for removing some particular areas in the metal so as to produce the required thickness, shape, and geometric features or complicated designs.

Chemical etching allows the producers to produce metallic components even with the most complicated and difficult designs, all whilst achieving consistent production quality and high repeatability.

How does the process work?

The conventional chemical etching process involves a sequence of essential steps:

1. Cleaning

In this step, the metal surface to be etched is prepared by getting rid of oils, grease, residues, plus some other pollutants. Cleaning happens to be a vital step given that a polluted surface might lead to improper adhesion of the photoresist film that can cause defects in the long run. When the process is completed, the workers must not handle the material using their hands since the material can become polluted by the oils and sweats from the human skin.

2. Lamination

In this step, a dry film photoresist is going to be applied to the surface. The areas of the metal which won’t be etched will be protected by the photoresist. These films will be applied to either side at the same time by laminating or rolling onto the material by making use of temperature, pressure, and at times water.

3. Exposure

The material, in this particular step, will be guided between a couple of “masks” having the negative image of the component that has to be produced. Either glass or mylar will be used for making these masks. Subsequently, collimated, high intensity, and ultraviolet light will be shined through the masks from either direction, thus crosslinking the film in sites where the mask images are not blocking the light.

4. Developing

The material has to be developed following the exposure. This particular step dissolves the non-crosslinked film chemically which is responsible for exposing the bare metal underneath. The material which is left safeguarded by the film will become the finished product in the long run.

5. Etching

After the development phase, the chemi etch chambers will be fed by the metal where etchant will be sprayed from the top as well as bottom at the same time. This procedure dissolves or etches the metal which is unprotected for achieving the desired item. Careful monitoring is needed by an etchant bath when it comes to the composition, concentration, and temperature of the etchant.

6. Stripping

The film will be removed from the etched material during this process by making use of one more concentration of chemistry.

7. Rinsing and Drying

During this phase, the product has become complete and the films are going to be removed. All residuals must be removed by significant rinsing. This process will be performed by making use of deionized water and reverse osmosis water.

Materials which are Ideal for Chemical Etching

Metals ideal for chemical etching consists of a wide array of nickel alloys, stainless steels, beryllium copper, copper, brass, as well as phosphor bronze.

Importance of Having a Respiratory Rate Machine at Home

The number of breaths a person takes each minute is known as RR or Respiratory Rate. Clinically, it represents the process of ventilation or the movement of air that are coming in and out of the main respiratory organ, the lungs. As per experts, a sudden change in the respiratory rate is the generally the first sign of deterioration as during this stage the body works to maintain the delivery of desirable oxygen to the body tissue. So, unable to recognise the early signs of such mentioned deterioration will definitely result in unwanted outcomes for the person or patient in question. Hence, comes the necessary of having an accurate and efficient respiratory rate machine to properly take care of patient.

Benefits of monitoring respiratory rate

Many studies have claimed that early detection as well as documentation of significant changes in vital signs, especially respiratory rate, is the best possible way to prevent respiratory failure 24 hours prior, which happens to be the initial sign of deterioration in patients being treated in ICU (Intensive Care Unit) ward. Furthermore, there have been reports which suggest that an abnormal respiratory rate is a better way to predicate a cardiac arrest within 48 to 72 hours than from changes in blood pressure and/or heart rate. Besides, monitoring and recording RR is an effective way to control and even cure (in some cases) chronic respiratory diseases like COPD (Chronic Obstruction Pulmonary disease), asthma and such others.

Tests like PFTs (Pulmonary function test) and other such methods are capable of providing informative and accurate assessments, however, the tests can only be conducted in a laboratory setting and are unable to provide a continuous monitoring which a patient living with these diseases need to get the day’s work done without any kind of incident on a regular basis. And this is the very reason why portable and compact respiratory rate machine has become a popular choice; even a must-have in some cases.

Benefits of an effective RR machine

There are many different such machines that are manufactured to be used in a home environment or on-the-go. They are available easily in both local and online stores and come with different advantageous features at different price range.

When a patient opts for such a RR machine, they are getting others features as well:

They are capable of multi-parameter monitoring, meaning they can even provide information related to ECG, heart rate and such others. So, the patient is getting an extensive view at his/her different bodily functions.They are user-friendly device which come with customizable alerts, logging, exporting and transmitting data. So, the patient has the option to set the device to suit his/her preference and lifestyle. At the same time, they can even keep a detailed record of his/her health to provide to their doctors and keep up with the treatment/recovery process.

Finding the right RR machine

Usually, the best ones will have components like senor belts and sensor electronics module which make it easily for the patient to use it all day and transmit the data over a wired or wireless interface with ease. Besides, the best ones can even provide measurements for temperature (both core and skin), IBI etc. A good respiratory rate machine will have fall detection, body position, motion alerts, good internal storage capacity (around 8GB), Bluetooth connectivity, long battery life, GPS as well among other features. So, do your research to find the right one for you or your loved one today!

The Use of Respiratory Rate Monitoring Products

Good health is an important asset of man. It is imperative that we take good care of our health. When we are healthy, we are able to lead a comfortable life. A healthy man is able to live life better than an unhealthy one. A healthy body means a healthy mind; when you have a sound mind you can be assured that a lot of mental and psychological problems will be eliminated out of your life. Therefore, it is important that you take preventive measures for safeguarding your health.
Among different health issues faced by man, heart related issues are very common and are growing rapidly over the years. Poor diet and unhealthy lifestyle has shot up the number of heart related diseases globally. So, it is highly suggested that you take care of your cardiac health. It is advisable to visit a cardiologist regularly to ensure any upcoming disease is detected early on.
You should focus on different aspects of your body to ensure you are healthy. Here we are going to discuss about respiratory rate. It is a globally known fact that respiration is mandatory for the life of man. In fact, it is an act of a living man. Respiratory rate means how many times you are breathing in a minute. There are respiratory rate monitoring products that allow doctors to monitor the rate of respiration of their patients. Also, there is a set number of times you are supposed to breathe in and breathe out. If your breathing rate is either lower or higher than normal then it means there is something wrong within your body. If the respiratory rate of a human being is below normal then it is a more serious issue. Oxygen is needed for the proper functioning of the cells of your body. If the oxygen does not reach the cells of a particular area then it is feared that the particular area will go bad. Therefore, if you notice that the respiratory rate of any of your family members is going down then you should visit an expert doctor right away.
When you take the low respiratory rate patient to the doctor in the early hours, you would do him a great favor. It might help the patient to stay safe from heart attack. When you notice a change in the pattern of respiration in any person, you should take the patient to the intensive care unit right away. When you take the patient to the hospital, the doctor would use one of the respiratory rate monitoring products in order to see the rate of respiration. If the respiration rate is beyond safe limit then emergency services would be rendered to the patient in order to save him from any serious issue.
Health warning signs are sometimes fatal if they are not detected at an early stage. It is imperative that you are always alert to know and detect the signs. When you are able to detect the problems in its initial stage then you know that a big problem can be solved that could occur at a later point of time. Make sure to use the right respiratory rate monitoring products to monitor the rate of respiration.

Analyse mobile

Outdoor training can be hard. Conditions are always changing. One day it may be raining. The next there may be ice and snow. Still the next day, it’s possible to confront problems such as an unexpected heat wave. This is where it makes sense for people and companies that engage in training methods for outdoors to think about how best to streamline this process and make it much easier for all concerned. It means that all companies need to have real world data that indicates how people are responding to the weather conditions around them. They need to know how someone is going to respond in the middle of a snowstorm or when it’s very hot outside. This means that all companies and organizations that engage in such outdoor activities and train people to respond to them need to find the best possible way to make sure they have such accurate data.
Using products such as analyse mobile means that everyone has the help they need to be able to use such data in the field. Gathering data is incredibly helpful as it offers the kind of real world conditions that people today must have. This means that each client also has the kind of data that has been repeatedly used in accurate conditions in the field. In doing so, they know how to help people to respond to any kind of changing conditions. They have accurate information about the people they are supervising. This data is gathered over time and can be watched and changed as necessary. Monitoring enables clients to have the data that will allow them to change things as necessary using accurate media on hand. This means they can develop more accurate strategies that are better for use under many kinds of real world conditions right now.

Home Air Conditioning Cambridge

Imagine its right in the middle of summer, temperatures are sweltering and suddenly your air conditioning fails. You try calling the neighbourhood repairman but he is not able to come; you contact a few other companies but they tell you that they can only get to your home after a few days. What do you do? You will probably start running around buying fans to try and keep temperatures down. You could have avoided all this if you had made a point of maintaining your AC unit on a regular basis.
You use your AC unit on an almost continuous basis, so it only makes sense that you have it looked at from time to time. These units break down when they are most needed and it can be hard to get timely repair. As a responsible home owner you should make a point of inviting the AC maintenance company to your home once in spring and once in autumn to make sure that your system is running correctly.
Finding the right AC maintenance company is important – you want a company that can do a professional job of keeping your unit in good repair. They should be familiar with your particular brand, and they should be able to anticipate problems so that they can get ahead of time. Sign a contract with them so that in case of emergencies they can come right away. A good AC repair and maintenance company will not overcharge you for services rendered, but they will not undercharge you either – they will always give you a written quote that is in line with the current market rates.
