In short, PVD is more expensive than CVD. Thus, the manufacturers usually use PVD coating on some high-end products for the decorative purpose, such as designer watches, jewelry, etc. If you want to know more about the cost, you can check another blog about the cost of PVD coating.

CVD is a chemical process, and most substrates ( products ) that are reactive can not be used. So, it also limits the most materials from which jewelry and watches are made.

Choose the PVD process if you want a smooth finish and a shiny metallic luster on your substrate ( products ). But if you want a more rough finish for your substrate ( product ), then CVD is best. Smoothness level can be controlled in both processes by controlling various factors, but overall, CVD coatings are rougher than PVD ones.

PVD and CVD are both highly advanced thin-film coating processes. Both of these processes need vacuum conditions and high temperatures for their working.

The plexiglass sheet market is forecast to grow from $5.3 billion to $7.9 billion by 2026. As a player in that field, Regal Plastics has a wealth of knowledge to share about how to cut plexiglass. Read the following questions for the answers you need.

Overall, the CVD process has fewer coating substances and is not safe. In contrast, the PVD process has a large number of coating substances and is safe to use.

But if you do not like your coating or want to change them, many manufacturers offer the service in which you can remove your already present PVD and CVD coatings.

In PVD, there are no chemical reactions, and mostly the substrate ( product ) is not heated in this process. So, almost any kind of substrate ( product ) material can be coated with this process, even plastics.

The two coatings are both prevalent and can be found in many consumer products. However, if you want to apply coating on the surface of jewelry and watches, the only coating can be PVD process.

Once you're done cutting your plexiglass sheets, you'll notice the edges will still be rough. To finish your cut edges, you should:

In the CVD process, the coating substances must be volatile, so only a small number of materials can be used as coating substances. Plus, these volatile coating substances are toxic, explosive, or corrosive and not safe to handle. These coating substances may also produce hazardous by-products in the chemical reaction, which are not easy to dispose of.

If you're wondering how to cut thick plexiglass sheets, a power tool is your best bet. Whether you use a table, circular, saber or jigsaw, you must select the right blade. Specialty plexiglass blades are available, but you can use any metal-cutting blade with carbide tips. Make sure the blade teeth are evenly spaced and have the same size and shape. Then you must:

The best tool to cut plexiglass depends on the thickness of the material and the intricacy of the cut. For cutting plexiglass 1/8” thick or thinner in straight lines, a utility or scoring knife should work well. For more intricate cuts, a Dremel or jigsaw would be a better choice. For thick sheets of plexiglass, you need to use power tools like a table or circular saw.

There is no one best way to cut plexiglass. But you have several options, depending on the tools you have available and the size of the sheet you're cutting. Whichever method you choose, the key is precision and patience. Let's take a closer look at some of the most popular methods of cutting acrylic (plexiglass).

In other blogs, I specially write the details about PVD jewelry and PVD watches. If you’re interested in PVD on these products, you can have a look.

There are even more applications for plexiglass, depending on the type you choose. Bullet-proof plexiglass is found in banks, convenience stores, cabs and other locations where security is a priority. Moisture-resistant mirrored plexiglass is used in gyms, ballet schools, locker rooms and other applications that benefit from its shatter resistance. Artwork, certificates, 3D objects, memorabilia and more are displayed in plexiglass framing that takes advantage of the material's innate clarity.

While in PVD, coating substances are solid, which allows us to use a large variety of materials. So, PVD is ideal for coating jewelry and watches with a lot of different substrate materials, such as gold, titanium, graphite, etc.

Yes, you can use a box cutter to cut thin sheets of plexiglass. Other options include a utility knife, scoring knife or specialty plastic-cutting knife.

In this article, you will learn about different aspects of PVD and CVD processes, such as their working mechanisms, advantages, disadvantages, and much more.

Now that we've discussed how to cut plexiglass sheets, let's take a quick look at the material itself. This plastic, technically called polymethylmethacrylate, is durable and shatter-resistant. Plexiglass's benefits include:

There are many differences between PVD and CVD coating processes, such as their working mechanisms, operating temperatures, coating substances nature, coating coverage area, film thickness, smoothness of coating, applications, and much more.

Due to an actual chemical reaction occurring on the substrate surface, this process is called Chemical Vapor Deposition.

Besides, there are 5 types of PVD methods. Each type comes with a similar working principle. They are dry coating methods.

Also known as acrylic, it's not hard to work with — if you have the appropriate tools and follow the proper steps. This article will provide all the information you need about the best way to cut plexiglass. Read on to become a pro at cutting plexiglass sheets.

In CVD, only those coating substances can be used, which are volatile at room temperature. So, coating substance materials are limited. For example, gold can not be used as a coating substance to coat jewelry and watches.

Disadvantages ofCVD

While PVD is a physical process, no chemical reaction occurs in it, making it ideal for all kinds of jewelry and watches, even if they are made from reactive materials.

Kraken carbide tipped hole saw is designed for extended life cutting fiberglass, wood, fiberboard, stainless steel, drywall, plaster, and laminates.

CVD is short for Chemical Vapor Evaporation, which is a thin film coating technique. During the CVD process, one or more volatile precursors are introduced in the reaction chamber along with the substrate.  The precursors react or decompose on the substrate surface to form a thin layer of coating. The waste gases escaped the reaction chamber by diffusion.

Except for being added as a coating, CVD can be also used to produce artificial diamonds. CVD diamonds now are more common in the market.

So you've settled on plexiglass as the right plastic for your application. But now that you're ready to proceed with your project, you're faced with a new question: How to cut plexiglass without cracking it?

But in PVD, the average temperature is 70° C – 398.8° C ( 158 ° F – 750° F), which is ideal for almost all the materials, even plastics.

In contrast, in the CVD process, the substrate ( product ) is heated up to 800°C – 1051.6 °C ( 1472° F – 1925 ° F ), which most substrate materials can not withstand. So, most substrates that have low melting points can not be coated.

If you're cutting plexiglass 1/8” thick or thinner in a straight line, you don't need to use power tools. To cut plexiglass by hand, you simply need your measuring stick and a box cutter or scoring knife. You can also buy a specialty plastic-cutting knife at your local hardware store. Then follow these steps:

In the PVD process, a coating substance goes from a condensed form into a vapor form and back to a condensed form as a thin film on the surface of the items.

PVD technology is widely used in the manufacturing of jewelry, door and window hardware, kitchen and bathroom hardware, lamps, marine supplies, handicrafts and other decorative products.
