LINA Multi-Functional Series
For years, in order to meet the updating and growing needs of "integrated machine" in this industry, LINA's engineers are committed to design multi-functional series machines whose function is "more than one machine". There are three modes under LINA multi-functional series:
1. Pelletizing-cooling Integrated machine.
2. Kneading-pelletizing integrated machine.
3. Kneading-preforming Integrated machine.
The series of LINA multi-functional machines are not only specialized for all kinds of rubber and plastic materials, but also designed for CIM (Ceramic Injection Molding), MIM (Mental Injection Molding) and powder metallurgy.
Main Innovative Points of LINA Multi-Functional Integrated Machines
LINA new designed multi-functional integrated machine successfully centralizes different unit functions into one integrated operation platform. There are several advantages like saving working area, high production efficiency, easy handling and transferring, and easy collection of dust and odor produced in operation process.
The innovation points of kneading and preforming integrated machine is that it is able to use screw or hydraulic method to extrude the material in the Dispersion Kneader to forming or semi-forming. LINA modular forming methods are sheeting, piping and pelletizing. LINA multi-functional series machines truly subvert traditional flipping type dispersion kneader, which sends materials to next step after mixing, the entire separated process has many uncertainties, such as material pollutions, taking more working area and increasing the generation of dust and odor.
LINA multi-functional series machines truly achieve "more than one machine" on one independent operation platform that is modular, intelligent, energy-saving and environmental protection.
Value Points:
1. Automation: Continuous kneading and pelletizing.
2. Eco-friendly: No gas masks needed while operating.
3. User-friendly: Quick release design for die head.
4. Modular: Based on user`s demand, manually material feeding can be updated to automatic weighted feeding.

In 2008, Audi equipped the R8 sports car with full LED headlights, which is the first in the industry. They are not only brighter than halogen and xenon headlights, but they are also more energy efficient. However, this technology is no longer a new gadget, and now the B-class sedan can catch up with the fun of LED.
Matrix LED lighting technology, but Audi's engineers did not seem to stop the pace of innovation, they introduced matrix LED headlight lighting technology in the A8 luxury sedan, with the Hella 1 dual lens. The difference between matrix LEDs and traditional lighting is that it splits the high beam into five reflective surfaces, each of which contains five software-controlled LED sources, thus eliminating the reliance on mechanical beam deflectors.
When driving at night, the matrix LED headlights will use the high beam illumination throughout the whole process. Once the system light source sensor detects that there is a vehicle coming in front, it will automatically adjust or turn off several LED units in the light group, so that the front vehicle will not Subjected to strong light.
UwePseler, Audi's R&D engineer responsible for lighting and visibility, told the author that matrix LED technology can help us better control the distribution of the light source to achieve good lighting. He also pointed out that the light source produced by the matrix LED is very close to Audi's definition of a good light source, because if the light can be turned on unscrupulously and there is light everywhere, then this is definitely a good light source.
Because a front camera that detects a change in brightness within 300 meters ahead is connected, when the current vehicle reaches a position 200 meters away from the vehicle, some of the individual LED lights are immediately turned off. After the vehicle in front passes quickly, the time for the LED light source to resume normal operation is controlled by the driver. For example, the Sport and Comfort modes respectively have a sensing distance of 900 meters and 400 meters.
In addition, the spectral quality of the matrix LEDs is the same as that of standard LED headlamps, with a color temperature of 5500K compared to a xenon illumination system of only 3000K. Matrix LEDs are more efficient because a single LED can be used when not needed. Turn it off by yourself and it is very energy efficient. However, it is similar to the normal halogen, helium or LED illumination beam angle, and remains at /-25. However, the LED deviation in the middle area is only 2, and the maximum deviation angle of the edge portion is 8.
Despite nighttime driving, road lighting is directly related to driving safety, but matrix LED technology also protects the safety of roadside pedestrians and large animals. Compared with the way traditional lighting collects camera data at the windshield, the A8's far-infrared night vision camera provides accurate data information directly to the vehicle's control system through Autoliv, which is placed at the grille to detect the heat of the front object. When a pedestrian or animal is detected in front of the vehicle, a specific number of LEDs in the light group will automatically align with the object and flash 3 times (below the head) to remind.
Matrix LED lighting technology can control a single diode light, with HELLA level 1 dual-lens lens, A8 headlights are more intelligent so how to prevent fogging of the light group? P? Seler and his colleagues are still using the standard LED headlights process, which combines active and passive ventilation.
Pseler explained to the author that when the car is still, the fan in the lamp starts to run, and the hot air in the lamp group is discharged to quickly remove the fog. While the car is driving, the fresh air is directly injected, which also has the effect of removing heat and removing fog, ensuring the normal operation of the lamp.
Pseler also mentioned that it is the most challenging technical problem he has encountered to package the 25 LED lights in the headlights and integrate all the functions. To develop certain regional markets, relevant laws and regulations are also a very difficult problem.
At present, this lamp technology cannot be used in North America. He said. The laws in these areas require headlights to use only a single source, and we have 25 separate LEDs. Despite this, he is still convinced that the matrix LED headlight design will soon be officially recognized in North America, and Audi has also been discussing and negotiating with relevant departments.
Pseler believes that this design is very helpful for driving safety. He believes that when officials see the huge guarantee that matrix LED technology will bring to safe driving, they will definitely agree to the technology in the North American market.
However, do you make friends? Audi's engineers are getting less and less on the road to innovation! After matrix LED lighting technology matured, they began to prepare for laser diodes. But in fact, the technology of this laser headlight has been preempted by BMW, and BMW said it will use this manufacturing process on the mass-produced i8 plug-in hybrid sports car this year. However, Audi also has a nirvana in his hand, that is, OLED (Organic Light Emitting Diode) lighting technology, this guy has a lot of benefits compared to the former two.
In the initial state, this material is simply a paste that spreads very thinly on an absolutely flat surface (for example, a highly polished display glass) with a coating thickness of less than 0.01 mm. After energization, the molecules of the paste emit photons and the OLED plane is thus illuminated. By adjusting the distribution of the power input, the lighting effect can be uniform, light and dark, or even dynamic. But it is more difficult to develop in depth, because unlike the light bulb at home, it must continue to work under extreme conditions. For example, if the outside temperature is already below 25 °C, it will have to continue working.
Pseler said in an interview,
At present, although laser technology is in the initial stage of the R&D cycle, it is very obsessive. As an optical engineer, I know that the smaller the light source, the easier it is to project in a fixed direction, and this is one of the most valuable places for laser diodes. When the car is driving at high speed, we can even make the base beam denser and stronger. Although it is just another light source module in the matrix LED headlights. But given the normal high beam of only 250 meters, such laser illumination can reach 500 meters!
Now that Audi and Osram are working together, the laser diode lighting technology will first appear on the R18 in Le Mans Endurance in July, but Audi said it will further develop products for passenger cars. Experimenting on the car is very interesting for the design, because the result of the product life loss is very intuitive, and if there is no problem in the car, then other series of production models are even more problematic.
Having said that, there are still differences between the two. The R18 uses a passive cooling system, and because the car is driving continuously, there is enough air flow to cool it. In the passenger car, it is connected to the LED module and requires a fan to help dissipate heat.
However, the author believes that lasers are currently not likely to be used as separate light sources, because their brightness is too weak, and not as efficient as LEDs, I am afraid that at least 10 years of this technology can be improved. However, like all semiconductors, the proportion of laser sources can be adjusted, but it is still necessary to further reduce costs, and mass production is more favorable for its development.
Maybe everyone will ask: How long does it take for this technology to become popular? Car cloud bacteria can't guarantee that all cars in 10 years will use laser lighting technology, and even the technology may be mature for 20 years. However, the application of this technology in other places can help it achieve mass production faster. Audi is currently considering the widespread use of laser technology in the cab because it is very easy to turn the beam into a light pipe. Maybe at the CES show next year, your friends will see cars that use this technology.
