hello. It's heavy work. thank you. This time, I went to interview AGC. This time I came to AGC for an interview. Speaking of AGC, the company name was Asahi Glass a while ago, but did you know? yes. You knew it was a lie You
didn't know it at the time of the meeting, right? yes. Sorry, I knew there was a 5-6 year generation gap. A little while ago, there was something like the AGC logo, so I didn't see Asahi Glass anymore . In fact , we have already gone to see the materials that are not on display at the exhibition . Please take a look at that one first . However, it is very convenient that the various materials and technicians on display at this exhibition are gathered together, so it is very easy to introduce them , so let me tell you about it here. I would like to ask, so let's go . Please guide me to this booth. What are you exhibiting here? This is the booth where AGC's automotive cover glass is exhibited. Actually, the cover glass for these two parts is called the part called the car navigation system CID and the speedometer cluster.
Anti-fingerprint coating compatible with touch panels Anti-fingerprint Anti-fingerprint Because the number of car models with many windows that emphasizes a sense of openness is increasing, anti-glare and anti-reflection coatings I'm going to paste So why not film? When you actually apply the film, the cold feeling of this glass is very lost. Therefore, AGC is particular about coating directly on the glass . I can't, but how about durability in that area? No, no, it's not like that, isn't it? The car is said to have a lifespan of 13 years. It has a durable coating that far exceeds that 13 years, so there is no need to replace it . A high temperature environment, exposure to ultraviolet light, and stains caused by touch overlap, so I 'm skeptical about it. However, it is also popular in Japan, Europe, etc.
This is a scene I am familiar with. Is it a casting mold? Yes, it's a mold This is an introduction to a mold. Until now, you needed a mold to make a mold, but a mold needs a mold, right? This is a mold like a sand mold, isn't it? To make a sand mold, you need a wooden mold . Don't you want that? Yes, no. With a 3D printer, it is now possible to create a sand mold (ceramic) directly without the need for a wooden mold for a 3D printer! What made you want to make this? Materials developed to make effective use of leftover by-products that were not used in other businesses. We reused glass beads and leftover sand to develop a new product.
Waste became a product. is it? Will it be a casting mold? I was worried that the material cost would be very high because it was developed for this purpose, but that's not the case . One at a time. Is there any advantage to doing that? I wondered why the brake caliper was put here because casting is a medium to mass production technology . I feel like it's meaningless to have just one piece.At the initial prototyping stage, it will be necessary when judging what kind of shape is good.I will use it as a mockup.
When it comes to making things by cutting, it's relatively common to cut a test piece out of a block of cast iron before mass-producing it. There is still a difference between cutting products and castings that can be tried, so being able to try several types of castings is a big advantage . This is very important. This looks like a very complicated model. It looks like it can be made in many different ways . LiDAR is a sensor that plays the role of the eyes in autonomous driving.AGC handles many important internal parts.LiDAR often uses infrared lasers.It becomes a system that measures distanceIn
other LiDAR The fact that you're exhibiting the optical components used in this means that LiDAR can't be done without this material, right ? We have commercialized the basics for making lasers . Depending on the situation, we also have options for using lenses. When a laser comes out, this lens system performs the role of polymerizing and collimating the laser. What do you have? Visible light becomes noise when it comes in. Ultimately, we want to take only infrared rays to the final receiver, so we use filters like this to cut visible light . The location has changed again . AFLAS is a fluororubber. Features of AFLAS High durability, chemical resistance, oil resistance, and insulation.
Examples of APLUS AFLAS usage. Hoses, tubes, sealing materials, O-rings, wire coating . The outside of the tube is made of laminated rubber, and the outside is normal acrylic rubber . I have an image that if an extra component comes in contact with the material, it will become defective at once.I can't believe that different materials are together like this . The fluororubber introduced here is a rubber material with a polymer structure that is designed to be extruded. no eh ? Can you do that? There are other rubber materials, fluororubbers, and metals. Lamination adhesion is possible. I
have the impression that this silicone rubber is difficult to mold. Silicon rubber and fluororubber are Ikechan . yeah? yes. very! Do you know how amazing this is? why can you do that? Rubber is often vulcanized, but increase the points there and increase the points? Cross-linking points This type has more cross-linking points than conventional types.
The vulcanization speed can be matched with other rubbers . Different materials can be molded and bonded at the same time. There is a technology to control it. There are many beautiful lines. What is this? This is an electric wire. It contains the flow line of the electric wire through which electricity flows, and it is coated with resin rubber and covers the holes . The good thing about fluorine is that it can withstand various chemicals and high temperatures . What kind of environment is it? Fluorine rubber can withstand high temperatures around the engine, and normal rubber will crumble due to engine oil, etc. What about durability? There is an image that rubber becomes hard as time goes by.The rubber that uses an additive that softens the rubber called a plasticizer hardens
over time, but most of the rubber on display does not use a plasticizer. There is no hardening ingredient in the first place , does it not harden? Characteristics of AFLAS (fluororubber) Strong durability, not easy to cut, not easy to break, hard to see inside . This is an unusual ETF film, isn't it ? So on the contrary, it seems to be an advantage . It's usually used for electric wires and it's better if it's hard to conduct electricity, but if you dare to leave other features as they are and just let electricity pass through, isn't the customer too selfish? But it's a manufacturer, so it's a material that has been unreasonable for the first time in a long time . However, I ended up doing that . Thank you very much for coming.I think it was a very limited exhibition, but you were able to see a very wide range of responses, right? Mr. Tonkotsu. There were various things. Do you pick up and research materials that are likely to be profitable if you talk about them? AGC's brand statement Your Dreams, Our Challenge We want to create something that meets the expectations of various people. What is your dream? For example, if you want to improve the natural environment, make new cars, or make cars lighter, we are making various things to fulfill the dreams of customers and society as a whole . I'm doing various research with this in mind. We are currently developing various things at the AGC Yokohama Technical Center in Yokohama, so please come and have a look . It 's okay, I 'll invite you anytime .
Thank you very much for your guidance What kind of facility is this? This is the agc Yokohama Technical Center, a new research building that will be completed in 2020. This is a collaborative innovation space where we researchers not only conduct research, but also collaborate with partners who come from outside. It's called AO, and we've set up a place called AGC OPEN SQUARE. Certainly , just by looking at it, there are various exhibits.
We aim to enrich the ideas of those who have received it . ? This is a glass cylinder made in the same way as when AGC was founded.The glass cylinder is cut open, expanded in a furnace, flattened, and made into sheet glass.This is
an intermediate product in the process of making sheet glass. At the groove, a large ball is attached to the tip of the stick, and centrifugal force is used to extend it steadily . It's steel, so the glass sticks to the end, so it becomes even heavier.
Dozens of kilograms of glass stick to it, and it's stretched while blowing . You're also researching the latest materials, just like you were at an exhibition . This shows the history of AGC , and shows the matrix of technology development and products . Raw material soda ash and kiln bricks became difficult to obtain due to the war. Started manufacturing soda ash and heat-resistant bricks, which could not be imported, and made a start as a chemical material manufacturer Heat- resistant bricks AGC's ceramics technology, which has various developments, started with the manufacture of bricks around 1917. It was around this time that ceramics were made, and soda ash was used as a chemical material. I think you saw fluororubber at an exhibition that led to chemical products such as fluorine handled by Nari AGC, but this is where fluororubber started . However, the manufacturing method is gradually evolving. Now we have the float method. The float method is a manufacturing method in which molten glass is poured onto molten tin, flattened, and then cooled to harden . By pouring it into the top, it becomes a perfectly flat surface, isn't it? That's right. I see
, the precision of the glass has improved dramatically here. Today's glass is completely flat, is n't it? Now it has evolved and can be made perfectly flat. There are many difficult glasses. Smartphones and liquid crystal glass need to be melted at high temperatures, even though they are difficult to manufacture. Not only the performance characteristics of glass products, but also the characteristics at the time of manufacture differ greatly depending on the type. For example, the bricks used for that purpose . It's heavy, isn't it? It's made of zirconia, which is slightly lighter than iron, which is heavy like a lump of iron. It's very dense and hard. You need hardness and density that won't be scraped away . Why didn't you outsource that? It's true that the war is already over, is n't it? I wonder why they decided to make their own bricks instead of purchasing them from their customers. We made the glass that had
to be made in the past , developed the process to make it, and made these bricks as equipment for that . You mentioned that it all started with making soda ash, a raw material, by yourself, and as a method for that, the ammonia method, which was the standard worldwide at the time, was used to generate soda ash and ammonium chloride, but this method caused pollution problems. After that problem (1960s), an ion-exchange membrane was developed, and a manufacturing method using it succeeded in separating compounds such as soda ash. It became possible to produce soda ash in an environmentally friendly way. It is used for sodium and glass, but the remaining chlorine is used for urethane, and it is applied to cleaning solvents such as freon gas and chloromethane . You've always been like that. Chemistry is called a chemical chain, and compounds are all connected like a chain . I want to use it.Is there a chance to use it? No, no, no, I
traced the history of AGC, but this is how the technologies that seemed to be separate at first glance at the exhibition were actually connected . I understood the greatness of each, but it was very easy to understand when I tried it again. Ceramic, rubber, glass, etc., all seemingly disjointed, but they are all connected by fluorine, or because the materials used in the past cannot be used, they are all connected . Thank you for your guidance . Thank you very much. So how was your tonkotsu? Isn't it a little far? ? Is it far? I thought it would be better if the main character was in the middle, so it's a bit difficult to talk, so let's move forward. How was it? It was very difficult, but I learned a lot . For example, if a customer asks you to make heavy aluminum, no, use iron.
In the case of AGC , fluorine has the characteristic of being slippery and difficult to stick to . It 's completely unreasonable to change it to have conductivity . We are ignorant in heavy industry, so to be honest, we don't know anything about chemistry . There are quite a few doubts as to whether we were able to provide the information we were able to dig deep this time, but in the summary column, we have posted a site called AGC Hub, so if you want to know more about AGC, please take a look. I visited the exhibition booth at the Tokushima Technology Exhibition.In October 2022, an event called CEATEC will also be held, so if you would like to hear directly from them, please go there .
