Recently, the news that Lexus was finally going to be made is flying all over the country. Once again, the official rumor has denied the future. At least for a few years, it will not be made domestically. Why does Lexus want to be the last to stick to imported cars when luxury brands in China have invested in domestic production? I think this is not unrelated to the spirit of Japanese craftsmen.
Lexus's overall design philosophy is L-finesse, which combines the words Leading-Edge and Finese, defining the uniqueness of each Lexus car. Because of the uniqueness, craftsmanship and craftsmanship of each car, Japan is more inclined to call the retired person, and it will take more time and effort to ensure the quality of each car. Today I was fortunate enough to talk to the two Japanese designers of the Lexus Design and Development Department and learn about the development of Lexus's entire body color and the craftsmanship of the interior craftsmanship.
â—Color design
In the aspect of color design, it will follow the overall design philosophy of L-finesse. For example, contradictory concepts such as tradition and innovation, Lexus's color designer chooses a relatively traditional color, but through the most advanced technology, the traditional color is higher. Get new life at the level and show new value. Chief Designer of Color Designer Tian Zhongchang said: Color design is very important, and bears the role of organically combining the interior and exterior. When considering the color of the body, it is the endorsement of the model that the unique voice of this car is our design time. It needs to be taken into consideration. In addition to the same car, when the appearance of color changes, but also expressed the customer's different personalities, is the so-called one car, one color, one world.
Lexus's color library consists of 30 colors, each color does not use the standard color number, but re-development based on vehicle positioning, which makes each color is unique in the market.
The development of the entire body color is not a simple matter. First, the color designer has to create the concept color according to his own inspiration. Color designer Seto Keiko said that the inspiration for RC Hyun was inspired by the color of the first time wearing kimono. It was a red full of parents' love. The red shoulder bag that went back to school was a red of hope and expectation; The red ribbon is the red of love; there are mature lips full of charm and elegance, and red and white dresses worn during marriage.
When the concept color is selected, it will be sent to a different paint supplier. The exclusive craftsman will make small batches of hand-made trials. Every few weeks, a batch of new swatches will be sent to the color design room until they are satisfactory. colour.
The color designer then evaluates these swatches. Each swatch must be carefully observed in indoor, outdoor, lighting, sunlight, shadow, rainy days, and even light changes at different times of the year and even at one time of the day to determine if the desired paint has been achieved. Color effect.
Before the color is finalized, the color designer will repeatedly communicate with the chief designer, sales person and coating engineer, and after the color itself is confirmed, he will enter the production process again.
In the spraying workshop, a unique spraying process is used to simulate the manual movement of painting robots and the manual operation of master technicians to create a body color.
2 color spraying
â—Color spraying
Lexus has two unique spraying technologies, one is supersonic spraying technology, and the other is multi-layer spraying technology.
Supersonic spraying technology:
In order to achieve the whiteness of the color designer's mind, such as Sapporo Snow, a cutting-edge technology called supersonic paint has emerged. This kind of sonic spraying technology is a five-layer painting process developed by Lexus. The upper layer is an ultra-thin coating with a thick color and embedded with white micro mica. The reflective layer can also transmit light; the middle layer is pearl mica layer; the lower layer is comparative Thick white coating, supersonic quartz white was born.
Supersonic spraying technology divides the body paint into two functional coatings: an aesthetically pleasing decorative coating and a functional coating that protects the body.
The decorative coating becomes smaller in size after drying, making the arrangement of mica particles more compact, improving the reflective ability and layering of the coating. Because mica particles combine the characteristics of light transmission and reflection, designers use this feature to create a more three-dimensional and dynamic body color.
The transparent self-healing coating rewrites the performance of the paint from the molecular level, has a more compact structure than the conventional coating, and forms a protective shell that is more robust and wearable, can be deformed after being collided, and eventually heals superficial scratches. In addition to its unique elasticity, the scratch-resistant transparent coating is also resistant to the effects of UV rays and acid rain, allowing the owner to use the vehicle without special treatment or maintenance.
Multilayer coating technology:
Lexus multi-layer coating technology was originally dedicated to concept cars. This process can make the car surface appear more depth and radiant, which is the effect that can not be achieved by the traditional spraying process. However, this spraying process is very complicated. If this process is to be adopted, the original production line must be substantially modified. The Lexus RC F is the first vehicle to adopt the Lexus multilayer coating process.
The Hyun Red specifically for RC and RC F models consists of 6 coats and 4 bake processes. Dazzling red uses two different colors of primer: silver and red transparent primer, greatly enhance the color plasticity. When looking directly at the coating, the silver base layer is like a mirror under a translucent red coating filled with small aluminum flakes. The reflective effect of the silver primer will make the red varnish look dazzling; when the coating is strabismus, due to the transmission of the red varnish Sex, coating color saturation and brightness will change with the viewing angle, creating a more depth and layering effect. It should be noted that the use of two colors in a painting process is very rare, and the tiniest tinctures in the colors are exaggerated, but Lexus succeeded in overcoming them.
The dynamic blue flame is created by a 5-layer coating and 4 baking processes, which is not to protect the electrophoretic layer of the base metal of the car body. The first is a coating called an intermediate layer or intermediate primer, which is a solid substrate for other coatings. Next is a blue metallic coating and a light-transmissive sealing coating. Further up is a translucent blue coating (fourth layer) and the last layer is a second clear layer surface varnish with scratch and self-healing capabilities.
The design that encloses the blue coating between the two transparent layers is to control the reflective properties of the coating and achieve a balance between brightness and depth. After each coating is sprayed, the entire vehicle is placed in a paint booth to be baked, and then hand-polished by the worker under the supervision of a senior craftsman, and then a new layer of spray, if repeated. It is this nearly demanding process that ensures that every coating is flawless and ultimately creates a deep, textured blue flame.
Orange is inspired by hot lava, representing the power of nature. In the spraying process, the bright orange is composed of five layers of coating and four baking processes. The shiny mica is used to brighten the paint surface in bright orange, and the second layer, which is usually gray, is deliberately changed to white. , further enhance the brightness of orange

Bamboo crafts:
In the automotive industry, Lexus is the only brand that uses bamboo as an interior material. In the eyes of the Orientals, bamboo is a gentleman and a person. At the same time, bamboo, which is a tree material, also takes into consideration the protection of the environment.
The artisan cuts carefully selected bamboo segments with a radial blade cutting machine, and then thins the bamboo segments.
The bamboo pieces are pressure-formed, steamed and dried at a high temperature to achieve precise moisture content, as well as antibacterial, compressive and insect resistance. The processed bamboo pieces are stacked on a mold, and they are stuck together by a high-frequency bonding machine and pressed into a semi-annular shape.
Then use four semicircular bamboo sheets to enclose the upper and lower skeletons of the steering wheel. After repeated hand-planing, polishing and sanding, the tube is made smooth. Finally, the craftsman hand-polished into the most perfect steering wheel shape. This is an extremely demanding job, and only skilled and experienced tradesmen can do the job.

Naguri name chestnut aluminum craft:
The Lexus Naguri name chestnut aluminum trim panel, a combination of woodcut art and modern technology thousands of years ago, is a manifestation of tradition and innovation.
The word Naguri stems from a Japanese wood shavings processing technique that has been circulated for thousands of years. In order to eliminate pests in ancient times, the local carpenter in Yanli County peeled off some of the bark of the chestnut tree. In order to increase the sense of beauty, he randomly sculpted the artistic patterns on the smooth tree core. In the 16th century, this practice gradually became a high-end art form. Japanese tea ceremony founder Qian Lixiu liked the wood carving and used it to decorate his tea room. At the end of the shogunate era of the end of the 19th century, the old Bushido was gradually replaced by the Western way of life, and the art of woodcarving was also declining. Today, there are very few famous chestnut carvers who are still alive.
Lexus takes this as its theme and uses a cutting and grinding process known as the peak of aluminum processing technology. It cuts and grinds 0.25mm of 0.6mm aluminum sheet and sculpts a unique diamond pattern as a whole piece of aluminum sheet. At the time of completion, it is also covered with a layer of dark, delicate and smooth touch, which not only protects the surface of the aluminum sheet, but also guarantees the best results of the newly polished pattern, adding to the artistic enjoyment of traditional Japanese craftsmanship. This process is impossible for stamping technology.
Laser engraving process:
The laser engraving process is the result of the cooperation between Lexus and the world-famous industrial manufacturer Yamaha. In the 25 years of cooperation between the two companies, the company broke the five elements of Jinkemu. The seemingly simple lines will create a unique interior style.
Through a number of meticulous steps, high-quality wood is made into thin slices, and then high-precision grinding tools press the aluminum plate and the wood into one. In order to avoid chromatic aberration, engineers use a high-precision electronic control system to instantly adjust the laser settings to etch precise, uniform textures on the natural undulating surface of the wood. Each laser-engraved panel has a unique texture.
