What is the difference between etching and engraving

 

Laser engraving and laser etching are unique applications of laser technology with their distinct profile requirements, benefits and characteristics. Have you ever wondered about the differences between laser engraving and etching? Although all of these terms are used interchangeably, they all refer to a different process when it comes to creating images, markings or designs on a selected material with a laser.

It is essential to update your terminology and understand the practical and technological benefits of these different laser applications. This way, you can determine what setting you should prefer for your next laser project. Here is a list of our main differences that distinguish between these laser methods.

Durability

Laser engraving is an ideal method for marking parts and objects where high wear is to be expected. If you engrave a jewelry design with a laser, it will fade quickly if the piece is touched frequently, as the depth is only 0.001 inches. The deepest cuts in laser engraving are ideal for creating permanent markings on a variety of materials. Laser engraving is not appropriate for safety-critical parts since the etching process can structurally damage or damage the engraved part. A Laser-etched markings are less durable and are suitable for surfaces with little wear.

Object size

The etching is suitable for small projects and thin materials. On the other hand, the engraving can be used for large materials.

Nature

While etching is the art of creating an image using acid that removes metal, engraving is a printing method in which an artist uses a pointed and sharp tool to cut lines on a metal surface.

Physical effort required

Etching requires less effort because the etcher pulls the design through the wax. On the other hand, more physical effort is required in engraving because a tool has to be used to cut the metal.

Versatility

Laser engraving and engraving are versatile and can be used with many different materials. Laser engraving is suitable for almost any material of your choice, including metals, wood, plastics, leather, glass, acrylic and also soft materials like paper. Laser etching influences the surface of the materials changes the reflectivity and improves the contraction. The best materials for laser etching are anodized aluminum, stainless steel, coated metals, ceramics and polymers. Laser marking is widely used in the industry to come up with permanent markings without causing any damage on the materials.

Effect on materials

The laser engraving creates a conical depression on the material surface. Laser etching creates a high-contrast marking on the surface of the material by evaporating only the surface layer of the material.

Why you need a small weather station?

The weather reports from mobile apps that many people rely on are from stations that might be miles away from where they are. Most often, there are some discrepancies in these reports compared to the actual condition. They might be small discrepancies, but they can mislead you.

You need a small weather station for your farm, school, business, or home. They are far much better and will do more than the usual weather app does. They will tell you exactly how the weather is doing in real-time by measuring the current atmospheric conditions such as humidity, temperature, rainfall, barometric pressure, wind direction, and wind speed.

Small weather stations also connect to the internet, allowing you to weather conditions remotely. You should not continue depending on the limited weather apps that are unable to tell you what in specific is going on out there. Prodata weather systems have great small weather stations that will suit your needs. They will give you more years of genuine and excellent service most weather apps can’t offer.

What is a small weather station?

A personal weather station or a small weather station is a set of weather measuring instruments you can install on your farm or home. A complete small weather station must have instruments to measure temperature, rainfall, pressure, humidity, wind speed, and wind direction.

Parts of a small weather station

Most small weather stations have battery-powered devices that are designed to collect and record data about the weather condition of an environment. They contain five parts or more:

Thermometer for measuring ambient temperaturesHygrometer for measuring ambient humidity levelsRain gauge for measuring the amount of rainfallAnemometer for measuring wind direction and speedThe barometer for measuring air atmospheric pressure

To understand how the entire weather station works, you need to understand what each part does. The features of small weather stations vary from one manufacturer to another. It is always better to research about a product of your choice before buying to avoid buying a small weather station that won’t fit your needs.

Choosing a small weather station

There are so many modes of small weather stations in the market, all with different price options. Finding the right one for you is difficult, but not impossible. Here are some of the things you should look for when shopping for your small weather station.

1. Radiation shield

The humidity and temperature sensors should be housed to protect them from direct sunlight to enable precise measurements. Some have a small fan that prevents hot air bubbles from disrupting the sensor’s work.

2. Rain gauge

You should look for the one with a big funnel and a data resolution of 0.01 to reduce errors when reading data.

3. Anemometer (wind measuring sensor)

There are two types of anemometers; spinning cups and propellor. There is so much difference between the two. Because anemometers tend to cache ice-cold humid weather, look for a black colored sensor with an accuracy range of plus or minus five.

4. Wireless transmission

Most small weather stations connect to WiFi. You should look for the one with a long-range of transmission (around 250 feet).

Chemical used in jewelry making

Jewelry is often one of the most precious possessions of an individual. It has been used by mankind since time immemorial. It is equally important for both men and women and wearing ornaments is loaded with cultural and social importance.

Jewelry is commonly made of metals and gemstones. However, other materials can also be used. Although designs and techniques vary by culture, Asia has had a significant impact on global jewelry making. The importance of ornaments cannot be underestimated and jewelry storage solutions are needed to store your pieces carefully.

Gemstones, coins, or other precious materials are often used for ornaments and are usually placed in precious metals, including alloys. Modern fine jewelry are usually made of gold, platinum, palladium, titanium or silver. Diamonds are also used to some extent, but they are quite expensive. Many gemstones and semi-precious stones are also used as amber, emerald, jade, quartz, ruby ​​and sapphire. Jewelry storage solutions are needed to store pieces in a way that avoids damage.

Silver has been mined since 4000 BC. The art of making silver objects has been around for centuries. Because it is malleable and durable, it has been used for many purposes, including the manufacture of jewelry, dishes, ornaments, coins and even celluloid. Often, it is usually silver made from other metals. Almost all metals, besides pure gold, naturally corrode when exposed to elements such as air. Even silver corrodes when exposed to moisture, moisture and air pollutants. Jewelry storage solutions provide ways to protect silver from corrosion so that its parts enjoy a longer life. Prevents or slows their deterioration while protecting them from corrosion.

Careful handling and storage can help prevent silver jewelry from deteriorating. They are best stored when stored in a low humidity environment. Ideally, silver should be stored in carefully lined jewelry boxes to prevent scratches. Another technique that can be used to preserve the life of your silver pieces is called lacquer, which is the process of creating a durable finish on the surface of an object. Chemical dives can also be used to polish silver and prevent corrosion. Newer procedures such as laser cleaning and plasma cleaning can also be used today. The need to care for and protect ornaments made of precious metals such as silver has led to the development of innovative jewelry storage ideas that can be used to prevent corrosion and degradation.

Although gold and gemstones have been popular since historical days for jewelry making, due to their rising rates, many other alternatives are found, and one of them is tungsten. Tungsten jewelry has received enormous popularity in a short period of time, due to its durability and unusual sheen. Before becoming jewelry, tungsten was known around the world in the form of a delicate cord that is present in electric lamps and ignites when electricity passes through it to give light. Currently, this material has been identified as right for jewelry making.

The main reason for the popularity of tungsten is its rigidity. However, tungsten is not firm on its own, that is, not when in a rough state. To provide the required hardness, your powder should be mixed with carbon and other metal such as cobalt or nickel. Especially for making tungsten jewelry, the material used is eighty-five percent of tungsten and 15% of other items. They are together to make a fine powder. This powder is then condensed to high pressure and then treated to an extremely high temperature in an oxygen-free oven. When this procedure is performed in tungsten, the metal becomes so rigid that its melting point is the second highest of all metals. Then cut into pieces that are formed and polished with diamond-tipped braces. And in this way, the pieces are transformed into various types of jewelry, such as rings, bracelets, etc. These jewelry are very durable and last even if the wearer suffers an accident or some other accident. In short, it can be used even when performing any difficult task. It is not cracked and does not wear or rust due to water or detergents. He has wonderful power to defend himself against curls and scratches.

Etching Facts

Photoetching is known by a variety of names, such as chemical milling, metal engraving, chemical processing, chemical etching and photochemical processing. This process can be wet or dry. Wet etching is the process by which metal dissolves in a chemical solution. In dry etching, the material is dissolved by steam or ions.

The whole photogravure process is a combination of basic engraving and photolithography. In the photolithography process, the patterns are generated by the reaction of enzymes in the molecules or by the use of substrates covered with photoresist. In this way, a photoresistance develops while the substrate is exposed to ultraviolet light. Then the substrate is recorded. The photoresist helps to protect the parts of the substrates that do not need to be recorded. This is a very useful method today to create finger protections or printed circuit boards.

Gray colors can be obtained by this photochemical grinding process by engraving the plates several times to produce different plate depths. The method allows the creation of complex details while making reproducibility difficult.

The process has opened a wide market mainly due to its functionality. The photogravure process is now used in various manufacturing units, in the electronics and metal industries and in some cases also in the aerospace industry. This method is also known as photochemical grinding or photo chemical etching. The electronics industry has used this process extensively due to its quality and high accuracy.

The whole method of photogravure is not that difficult. In fact, it is very useful for metal components, especially when bulky work occurs. The process helps to create templates, circuit boards, mechanical models, etc. The whole photogravure method requires a lot of attention and subtle control. The process is fast and requires a very economical configuration. For engraving, various metals such as stainless steel and alloys that have corrosion resistance can be used. Even very thin metals or sheets, hard or brittle materials can go through this process.

The photogravure meets the enormous requirements of RF shielding, EMI shielding, PCB, etc. Fingerware is often used in electronic products mainly due to its high conductivity. They consist mainly of beryllium copper and are chemically etched in a good way. Use this process to get huge benefits when working in the electronics industry.

All You Need to Know about Cup Anemometer

Dr. John Thomas Romney Robinson of Armagh Observatory designed a simple type of anemometer in the year 1845. It comprised 4 hemispherical cups which were installed on horizontal arms fitted on a vertical shaft. The shaft was turned by the flow of air past the 4 cups in a horizontal direction at a speed that was almost proportional to that of the wind. As a result, the average speed of the wind was calculated by counting the number of turns made by the shaft over a specified timeframe. This device is also known as a rotational anemometer.

It is simple to see the 4 cups of the anemometer since these are arranged in a symmetrical fashion at the end of the arms. The hollow of one cup is always presented to the wind which is blowing at the rear part of the cup on the reverse side of the cross. The drag coefficient of a hollow hemisphere happens to be 1.42 on the hollow side and 0.38 on the spherical side. Therefore, it generates more force on the cup which is offering the hollow side to the wind. Due to the asymmetrical force, the torque which is produced on the anemometer’s axis makes it spin.

Hypothetically, it is important for the anemometer’s rotation speed to be proportional to that of the wind since the force which is produced on any object is proportional to the fluid’s speed which is flowing past that object. This consists of the turbulence which is generated by the device, thus increasing the drag against the torque which is generated by the support arms and the cups plus the mount point’s friction.

When the anemometer was first designed by Robinson, he declared that the cups actually moved 30% of the wind’s speed which was unaffected by either the arm length or the size of the cup. Although it was confounded by some autonomous experiments performed earlier, it was not correct whatsoever. An error was detected and every single experiment conducted previously had to be repeated.

John Patterson developed the 3-cup anemometer in the year 1926 and a cup wheel design was formulated by Brevoort & Joiner of the US in the year 1935. This particular device produced an error of less than 4% up to 97 km/h wind speed. It was found by Patterson that every single cup produced the optimum torque once it was at an angle of 45 degrees to the flow of the wind. This 3-cup anemometer also generated a more consistent torque and responded faster to gusts as compared to the 4-cup anemometer.

Afterward, in the year 1991, the 3-cup anemometer was modified by an Australian named Dr. Derek Weston for measuring both the speed of the wind and its direction. This individual included a tag in one of the cups that caused the speed of the cup wheel to increase and also decrease while the tag moved with and against the wind alternately. The direction of the wind is computed from all these modifications in the speed of the cup wheel while it is possible to calculate the speed of the wind from the average speed of the cup wheel. This type of cup anemometer is presently used in the industries on a wide scale right now instead of the 4-cup version.

Know the benefits offered by chemical etching process for designs.

Chemical etching” is a process of engraving on different materials with the use of high temperature and high pressure chemical spray that helps in creating a permanent etched image on the metal.
