Cooler for die castings

May 19, 2016 by Leave a Comment

[INQ. NO. 1605M31] https://korean-machinery.com///inquiryCoolers by Wonjin Co., Ltd are a component of die casting molds for automobile engines. The cooler chills heated die casting mold(s) by injecting cooling water into the molds. Thanks to the company’s special brazing technology, the cooler is completely watertight and fl awless.

2016-05-19 09;35;05.PNGComponents for automobile engines are made of aluminum, and they therefore need special molds for die casting. Coolers from Wonjin are used in the process to inject cooling water to chill the heated molds. Aluminum melts at 660°C, which means that the repeated casting process keeps the molds heated at high temperature, and may hinder separation of the components from the molds. The cooler is needed to ease the separation process by injecting water into the molds to cool them down, thus decreasing the defect rate, enhancing productivity, and prolonging the durability of the molds.

Since its foundation on April 1, 1997, Wonjin has specialized as the only company providing special brazing, along with components and coolers for die casting molds in South Korea, with its relentless and challenging eff orts and R&Ds for more than 15 years. Wonjin has exported its products to nine companies in six countries, including Germany, France, Japan, and Spain, and supplies its cooler products to Renault Samsung and Toyota.

Development of sensor for sensing the brake lining

March 17, 2016 by Leave a Comment

Technology overview: https://korean-machinery.com///inquiryAt present, the Lining Wear Sensor (LWS), notifying the worn-out condition of the lining among the domestic automobile parts, is entirely occupied by the product of H Company, a European automotive electronic component company. However, following the requirement of the digitization and the communication mode, merits of the Inductive, an electronic sensor (non-contact type), have been magnified, thereby changing as a global trend.

H Co’s LWS judges the worn-out degree using plenty of Hall-ICs by the sensing method of Hall-IC type, and then informs the driver of the replacement time of the lining. On the other hand, the Inductive sensor technology of TRUWIN Co., Ltd. using the law of electromagnetic induction is the product which does not need the permanent magnet nor need to consider the characteristic of the magnetization curve of the magnet and the temperature, and it is composed of the sensor part coil sensing the movement of the pedal, the exclusive ASIC design for drive of the whole system, the FET drive circuit of the ECU transmission signal, etc. And we also have enhanced the reliability and the accuracy by grafting the microprocessor as well as upgraded the existing non-contact inductive method in order to be capable of sensing the wide angle . We plan to increase the technology share in the domestic automobile market through development of the sensor like this, and keep on securing price competitiveness in the global market through continuous technical development.

Industrialization: As the inductive sensor design for sensing the wide angle, requiring the program design for the development of the microprocessor and development of the optimal product for the automotive environment, has a considerable level of difficulty in verifying the reliability, it is the cutting edge technology to the extent that at present only three companies can develop the product in the world. TRUWIN has succeeded in localizing almost all of the parts and technologies of the inductive sensor. Having achieved recognition of such excellence, we passed the quality verification system of our customer companies in 2014, thereby applying our product to the domestic vehicles produced in large quantity, and we are mass-producing our product as it has been applied distendedly, step by step. In the overseas market, we are in consultation with M Company regarding various options for entering the Europe market, and we expect to control about 10% of market share in the global commercial vehicle market when we find our way in the world market.

Problem-solving in industrialization: At home and abroad, there is no company owning the technology of the product developed by TRUWIN Co., Ltd (the sensor for sensing the non-contact brake lining using the inductive sensor). The product of H Company has to inevitably use a permanent magnet as it has adopted the method using the Hall element, and thus has the problem of assuring the temperature characteristic of the permanent magnet and solving the weakness for the increase of the cost price. The product of ‘sensor development for sensing the brake lining’(LWS) using the Inductive sensor developed by TRUWIN Co., Ltd. through the ATC project can solve the above- mentioned problems, and it is outstanding and excellent in the aspect of insuring the quality stability and price competitiveness. In addition, we are striving for continuous research and development in order that the LWS developed by TRUWIN Co., Ltd. can be applied to the product specifications by model as the product for the commercialized vehicles. By possessing the fundamental technology in consequence of research and development over the past two years, we expect to secure market competitiveness and advance as a global enterprise and create added value.

1200MPa-level high-strength connecting rod-making technology

March 17, 2016 by Leave a Comment

Technology overview: Connecting rods used in automobile engines are the power transmission part converting the linear motion of the piston into the rotating motion at the https://korean-machinery.com///inquirycrank shaft by explosion of fuel, thereby requiring high strength and toughness, and fatigue strength. In addition, recently as the demand for high-strength connecting rods increased with the development of high-powered engines (GDI, T-GDI etc.), we needed the mass production technology of high-strength and high-precision connecting rods, thereby developing the relevant technology. In this study, we have secured the mechanical properties capable of responding to the high-powered engine through the high- strength powder alloy design for powder forging, and have reduced number of processing times and improved the mechanical property relative to the competing production methods by complementing the optimized design of mold (Net-Shape) and the post-treatment process.

In addition, based on the connecting rod design technology using the computer simulation, we have succeeded in producing the connecting rod for high-powered engine. By producing and supplying the test specimen and the test product developed without investment and change of equipment in the short term on the basis on these technologies, we have evaluated the product and applied the mass production system in early stages. Recently with the increasing demand for high-strength and lightweight connecting rods following the downsizing trend of high-powered engines, the recent issue of the automobile industry, it is expected that the demand trend of such connecting rods will be applied to both domestic and foreign markets, thereby doubling the economic effect.

2016-03-17 09;03;50.PNG

Industrialization: We succeeded in mass-production of the developed connecting rod without change of the existing production line or additional investment, and beginning with application of the rod to the 2000cc T-GDI engine of Hyundai Motor Company in 2011, we applied the rod to all of the models mounted with a gasoline engine of 2000cc or larger (four models mounted with a 2000cc Theta Engine, three models mounted with a 3000cc Lambda Engine, and one model mounted with a 5000cc Tau Engine) of Hyundai Motor Company in 2013, thereby achieving turnover of about KRW 54 billion from 2011 to 2014 (KRW 2.4 billion in 2011, KRW 14 billion in 2012, KRW 18 billion in 2013, and KRW 20 billion in 2014, respectively). In addition, we also came to achieve the effect that the items of the localized parts pursuant to the reinforcement of Hyundai-KIA Motors’ localized production were maintained by or converted to domestic production. Therefore, it has become more likely that our connecting rod will be applied distendedly to various automobile parts requiring high-tensile and high-fatigue features, and it has become possible for the overseas competitors to produce, substitute and supply the connecting rod in Korea vis-a-vis the localization investment in China. Thus, it is expected that increase of export will be possible as the factories of GM, FIAT, etc. located in China are also reviewing development of the product.

Problem-solving in industrialization: Composition of the alloy powder mainly used for producing the connecting rod with the powder forging process before the research and development was Fe-Cu-C based alloy, and its tensile strength was 800MPa level having difficulty in being applied to the high-powered engine. In order to secure hardness, overseas competitors produce the product by increasing the content of copper(Cu) and sintering at high temperature (1,250℃), there is a limit in securing the property only by adjusting the content of copper and carbon(C), and increasing  the sintering temperature causes the increase of investment for the processing equipment and processing cost. In order to solve this problem, we have concentrated on developing new alloy material for the connecting rod capable of responding to the high-powered engine without introduction of new production method or change of owned equipment. Besides, we could succeed in industrialization by mass-producing the product early as rapid evaluation of the product and complement verification of technology and quality were implemented for the development product attributing to the concentrative research and development through the connection of both the enterprise-oriented industry∙institute research system and the production∙demand enterprise.

Digital UV inkjet press

March 17, 2016 by Leave a Comment

Technology overview: Offset, Flexo, etc., the existing typical printing methods, are the analog printing method requiring the process of more than 10 steps in order to acquire the desired results. For example, after plating the color separation film by color, the experienced experts have to adjust the alignment of each color plate. However, with the UV inkjet press developed and industrialized by DILI Corporative Company, you can check the result immediately after having inputted the digital file, https://korean-machinery.com///inquiryand also can enjoy the cost-saving effect, along with the fast output speed, through variable data processing, eco-friendly printing environment, and process simplification which were impossible in the existing analogue printing. In order to realize the digital UV inkjet press like this, DILI has developed the inkjet control technology which forms the image by controlling individually the injection amount of thousands of inkjet nozzles with the level of pico liter (a trillionth liter) on the media transferred with high speed of 50 meters per minute, the high-power UV curing system which cures the injected ink, the output bed optimization technology, the high-accuracy position control system, the automatic head cleaning and capping system, the media tension adjustment algorithm, etc., thereby having optimized them with one another. Though the Korean manufacturing industry reveals to prominence in the world, the printing machine alone showed inferiority compared with Europe and Japan. However, we have received the evaluation that we marked a new milestone through the fundamental technology and product development related to this digital UV inkjet press. We have received the IR 52 Jang Young-sil Award in recognition of the excellence of the relevant product and applied technology.

Industrialization: More than 10 digital UV inkjet press, industrialized through years of development and investment, have been installed at home and abroad, thereby getting the attention of the market at the same time of being launched. The digital UV inkjet press market utilizing the inkjet is in its embryonic stage and on account of the high technical barrier, explosive growth of the market is expected with DILLI and several globalized enterprises having already entered the market as the center. Especially, due to the unique advantage of the digital equipment, replacement demand and interest of the customers owning the existing analogue equipment have greatly picked up. In addition, DILLI’s industrialization of the digital UV inkjet press is a barrier to imports against the foreign-made equipment, and also contributing to increase of exports. In the beginning, DILLI’s equipment was designed to be capable of printing out at the speed of 50 meters per minute with the maximum output width of 216mm and using 5 colors. However, reflecting the demand from both domestic and overseas markets, now the model line is strengthened to be able to print out with the maximum width of 324mm.

Untitled-22.jpg

Problem-solving in industrialization: Although we secured the core technology through development of the algorithm for controlling thousands of inkjet nozzles individually,  optimal concave surface design for securing the media oblateness on the printed face, development of the UV curing system, etc., we have faced with the problem of having to align 15 inkjet heads accurately for obtaining the better product of printout. Therefore, DILLI developed the head alignment system capable of fine adjustment easily from the customers’ point of view, and then has completed application for PCT and registration of patent at each relevant country. Through this, we are receiving favorable reaction in the market with the differentiated quality of enabling the installation within a short period compared with competitors as well as improvement of the product of printout.
