Meanwhile, Profile keycap is a parameter used to indicate the height and tilt of the keycap. Each keycap keyboard will have its own profile to provide customers with different typing experiences and aesthetics to bring the most flexible and comfortable working space for users.

Why should you use Keycap?

Currently, keycap mechanical keyboards are used quite popularly and widely for the following reasons:

1. Provides a better typing feeling than a conventional keyboard.
2. Allows users to type with faster speed and greater accuracy.
3. A beautiful accessory that helps decorate and increase the aesthetics of your personal workspace.
4. Express the user's personality and interests.
5. Increases excitement for users throughout the working and studying process.

What material is the keycap made from?

Keycap keyboards can be made from many different materials and below are the most common materials.

1. ABS plastic

ABS stands for Acrylonitrile Butadiene Styrene. This is a type of plastic that is quite commonly used in today's life. ABS plastic not only has high elasticity and good impact resistance, but also has a relatively cheap price, so it is suitable for the majority of consumers.

Keycap keyboard models made from ABS plastic often have quite beautiful and bright colors, easily attracting the user's attention. Besides, when touching the ABS plastic keyboard, users will feel solid and sturdy. When typing, it will make a clear clicking sound typical of a mechanical keyboard.

Advantage:

1. High durability, good bearing capacity.
2. Low price.
3. Diverse designs and styles to choose from.

Defect:

1. The surface of the keys is prone to getting shiny after long periods of use.
2. Keys may turn yellow if exposed to sunlight.
3. Highly slippery so grip is poor.

2. PBT plastic

Besides ABS plastic, PBT plastic (Polybutylene Terephthalate) is also a very popular plastic today. This type of plastic has a rougher surface and is stronger than ABS, so it is often used to produce keycap keyboards in the high-end segment and above. On the other hand, because PBT plastic crystallizes quickly, it requires manufacturers to have expertise and high skills to be able to manipulate this type of plastic.

The keycap keyboard is made from PBT plastic and when typing, it will make a quite loud 'popping' sound. Normally for keyboards that are not too expensive, the keycaps will be made 100% of PBT plastic, and the frame will be a combination of PBT and ABS plastic.

Advantage:

1. High elasticity, good heat resistance.
2. The keyboard after a period of use does not become yellow and shiny.
3. The rough surface gives a smoother and smoother typing experience.
4. Good dust resistance.
5. Easy to clean and sanitize.

Defect:

1. High price.
2. Fragile and prone to warping if hit hard.
3. Few colors, mainly dark and muted.

3. PC plastic

PC plastic or (Polycarbonate) is a type of plastic with high hardness and transparent color, so it is often preferred to be used to make keycap keyboards with LED lights. Although not as popular as ABS and PBT plastic, users can still find high-end keyboards using this material from the Razer brand.

PC plastic can be used to produce keycaps separately or mixed with other plastics such as ABS to form ABS-PC.

Defect:

1. Easily leaves scratches due to strong impacts, causing loss of aesthetics.
2. Users are required to clean regularly to maintain the transparency of the product.

4. POM plastic

POM (Polyoxymethylene) is a type of plastic that possesses excellent scratch resistance, resistance and anti-cleaning properties. Because this type of plastic is classified as top quality and is quite expensive. 

However, because the price is too expensive and this type of plastic is difficult to manipulate, the number of manufacturers using POM plastic to produce Keycaps is very rare. Normally, POM plastic is only used by a few major component manufacturing brands to create exclusive keycap keyboards for the company.

2. Difficult to craft.
3. Surface adhesion is low, creating a slippery feeling when typing.

5. PVC plastic

PVC (Polyvinyl Chloride) plastic has the characteristics of being quite durable and hard. The popularity of this type of plastic is second only to ABS plastic. PVC plastic is often chosen by many technology companies to produce keycap keyboards because of its low price, high popularity, as well as the ability to manipulate more simply than other types of plastic.

However, compared to ABS plastic, PVC plastic only has average hardness and resistance. Therefore, the product does not have good heat resistance and is easily affected by ambient temperature.

In addition to plastic, there are also many types of keycap keyboards made of metal. These keyboard models are not only highly durable but also extremely sophisticated, unique and eye-catching in design. The most common metals used to produce keycaps are aluminum, zinc and their alloys. Because these materials are quite light in weight and suitable for making keyboards.

Metal keycap keyboards often cost more than ABS plastic due to high requirements in production and processing. But in return, the keyboard has a beautiful and fashionable design, able to conquer even the most demanding customers. In addition, users can optionally print text, images or engrave embossed icons on the keycap keyboard to create a unique and personal touch for this accessory.

Advantage:

1. High durability, good impact resistance and heat resistance.
2. Unique design, fancy and easy to attract users.
3. Diverse colors and designs to choose from.

Defect:

1. When typing, it makes a loud noise and easily attracts fingerprints.
2. Price is expensive.

Keycap molding and printing method

Currently, to print alphanumeric characters on keycap keyboards, manufacturers will use one of the following molding and printing methods:

1. Pad printing: This is one of the most commonly used keycap printing methods today. Because of its low price and simple production method. However, this method is not very durable. When printing keycaps with Pad Printing, the manufacturer will select available characters and place them directly on the key and then print directly on them. Then they will add a few layers of preservation to keep the ink from fading longer. 
2. Foaming: This method will use light from a laser to create a thin film of tiny bubbles. The purpose is to draw letters or numbers on the keycap. However, these bubbles often have a rather rough surface so they are easy to get dusty and turn yellow.
3. Laser etching : Similar to Foaming, this method still uses lasers to engrave words on the keycap. The energy source from the laser will help burn the plastic at a moderate depth and create the desired characters. The biggest disadvantage of Laser etching is that they can only be applied on white keycaps. 
4. Laser printing : Simply use a laser to print on the keys.
5. Laser etching with paint fill : This technique works similarly to laser etching, however after engraving is completed, color will be poured into the engraved position to create diverse colors for the keycap. Laser etching with paint fill method can be used to engrave characters for black keycaps and many other colors.
6. Laser engraving: The keycaps will be painted with a black UV coating. The manufacturer will then use a laser to discolor the paint layer and reveal the previously painted character. This method is mainly applied to keyboards with accompanying LED lighting systems.
7. Double shot : This is one of the most durable keycap printing methods today. Accordingly, to limit the discoloration of the character coating over time, the manufacturer will mold 2 separate layers of plastic, one for the keycap and the other for the characters. Thanks to that, the characters not only do not fade but are also displayed clearly and sharply.
8. Dye-sub : With this method, manufacturers will use heat to penetrate the ink deep into the keycap surface to increase the durability and sharpness of the coating. However, this method is only suitable for printing dark characters with dark backgrounds.

Popular types of keycap profiles today

Each type of keycap will have its own profile as a basis to help users choose the product line that suits their needs. Below are the most popular keycap profiles today:

1. OEM

Topping the list of the most popular keycap profiles today is OEM (Original Equipment Manufacturer). OEM keycap keyboards are often designed in a sculpted profile style, meaning the keys in each row will have different heights and tilts. 

The purpose is to provide comfort to fingers when typing. Besides, the surface of the keycap will also tend to curve slightly to hug your fingers and limit the protrusions that cause discomfort, helping users type faster and more accurately.

Instructions for testing keycap durability and bearing capacity

To test the durability and bearing capacity of the keycap, users can apply one of the following methods:

Check domestically

Normally, keycaps made from PBT plastic will sink faster than ABS plastic when dropped into water. Besides, if keycap keyboards are produced using laser engraving technology (engraved or filling), they will have a higher bubble density than conventional printing methods.

Test with Acetone 

To know if the keycap you are using is made from ABS plastic or not, you can try dipping them in acetone solution. If the characters on the keys are faded or corroded, it proves that these keys are made from ABS plastic, not PBT or POM.
