The company of Alfred Kärcher of Germany of cleaning machine of K__rcher high pressure in using (triumphant gallop) the modular core that follows form refrigeration function through making in mould of its Injection Molding appliance has, every the cooling time of goods of plastic outer covering shortened 55% , the Injection Molding that elevated a firm greatly manufactures efficiency. Core of this kind of special model is designed by Leinishao, use a metal to add material to make technical production. Company of setting Germany Alfred Kärcher (triumphant gallop) high-pressured cleaning machine of production already made the clean equipment with numerous Germany necessary family not only, and also suffer an user to favor fully on the international market, the striking feature of these cleaning machine is its bright-coloured and marked yellow crust. As a result of the powerful function of cleaning machine of Kärcher high pressure and good public praise, no matter be indoor,still be outdoor, more and more people used the product of Kärcher in daily cleanness of the family. To satisfy the demand that global market increases increasingly, kärcher should produce number every year with 1 million compact model cleaning machine. Annual sheet is Obersontheim the shipment volume of the cleaning machine of high pressure of K2 standard type of a factory exceeds 2 million. However, although already achieved so high yield, kärcher still cannot satisfy overall market demand. Challenge Kärcher cleaning machine is provided most differentiate the bright yellow crust that one of spent features are it, but crust is made also is one of main bottleneck in producing a course at the same time. For example, the crust of K2 set cleaning machine is produced by machine of 6 Injection Molding, every machine can be made everyday 1, 496 crust, but this one capacity is far insufficient to Kärcher, because Kärcher has 4 to assemble product line, the worker divides an uninterrupted production, so cleaning machine of daily K2 high pressure assembles a quantity to be able to be amounted to 12, 000. Apparent, a kind of choice is to acquire more Injection Molding machine. However, look in Leopold Hoffer of the member that coordinate, the controller of working procedure of the Injection Molding inside the Obersontheim factory that he is Kärcher, can pass mining to have equipment latent capacity to improve manufacturing efficiency. "Our target is to will shape cycle shortens from original 52 seconds for 40 arrive between 42 seconds, " his explanation says. The LBC Engineering company that for this he contacted headquarters to be located in Pliezhausen (this company already was bought by Leinishao in May 2013) , seek shorten the method of mould cooling time. What the carapace after the carapace after K2 yellow produces the yellow of original design K2 of the mould produces a pattern is brand-new design, have along with solution of form refrigeration function " the first phase of the project is the data that gets existing mould, the target that with this affirmatory Kärcher raises is feasible, " memory of Sken of ü of harmonious person Carlo H says the project of Lei Ni carry on of Kärcher. The heat that the data scale that Leinishaoli offers with Kärcher gives working procedure of existing Injection Molding is become like the graph, use Cadmould next®3D-F simulation software undertakes an analysis. The result makes clear, the fused temperature of model material is 220 ° C, temperature of drawing of patterns is 100 ° C, and in 52 seconds whole shape inside cycle, cooling time took 22 seconds. Mould temperature undertakes controlling with cooling water, flow rate is 10 litres / minute, temperature is 35 ° C. Next, leinishao resembles the heat that detects in the process undertaking the key builds a model to be being heated up, because these area are brought about directly,shape periodic extension, need undertakes further analysis to its. Use these data, carry on finished thunder Buddhist nun to contain 20 to shape periodic data imitate, include the analysis of pair of mould wall temperature among them. According to the proposal of H ü Mr Sken, when undertaking imitate the 2nd times, leinishao improved the temperature of nozzle side to control fashion, pass the mould in nozzle side namely board inside the cooling water course that joins two traditions, the cooling effect of the connect of whorl of beryllium copper circle that increases pair of mould board to go up. Subsequently, leinishao undertook imitate twice again, evaluate with this improve what obtain possibly when application follows form refrigeration potentially. Traditional mould refrigeration pattern is in the bore in the mould, in order to form channel of meshy cooling fluid. By the channel that bore means forms its geometry appearance can be restricted, to simpler mould, this kind of cooling means can be achieved expect the result, but to more mixed pattern, cooling effect can sell at a discount greatly. Use the modular core that follows form refrigeration pattern, used a metal to add material to produce a method, namely core of this kind of model is to use the means that add capable person to chase a treatment to come out. Add material to make way very agile, this means the complexity of passageway of the cooling fluid in the mould to accept restriction scarcely. Usually, can keep inside the mould as equal as the distance of mould wall along with form refrigeration passageway, because this is cooling the effect is more even; The section that perhaps focuses in the heat inside the mould, can increase those who follow form refrigeration passage is concentrated degree, offer faster refrigeration for these area with this. Imitate process shows, use after following form refrigeration, actually the cooling efficiency of area of almost all heat all attainable effective promotion, the thermal drop of mould wall is small amount to 70 ° C. Finally, in the mould one sets the area that follows form refrigeration passage without enough space, kärcher improved products plan ably, alleviate with this shape cooling problem. According to imitate result, leinishao put forward to improve plan in the round for Kärcher, point out the temperature of area of the heat in following form refrigeration to be able to be used at improving a mould is controlled, make the cooling rate of each parts more even thereby, reduce integral cooling time. The mould design after revising joined two modular core that add material to make, can offer to affirmatory heat area along with form refrigeration function. Carry on of core result Lei Ni uses the model of steeliness of 3D Printing of metal of beryllium matrix core that makes tradition of medium cleaning machine of K__rcher K2 high pressure heat becomes the effect that checked the mould design after revising like the technology, the temperature that confirms mould wall can reduce 40 ° C to come 70 ° C, cooling time can shorten from 22 seconds to 10 seconds, decreased 55% . Kärcher notes the chief Volker Neu of model technology group to also pass actual production proof, the readjust that new mould design adds craft of pair of a few periphery (fill makings system, processing system to wait) , but will shape cycle shortens from 52 seconds to 37 seconds. Now, the crust daily output of machine of every Injection Molding but from 1, 496 increase to 2, 101. Subsequently, kärcher also undertook improvement to the design of other mould. Leinishao uses the modular core that adds material to made a technology produce these having to follow form refrigeration function, h ü Mr Sken was Leinishaodi to offer active support in production process. Mr Hoffer ever supported distrustful attitude to this project at first, now his say: "Compare forecast as a result be close friends, leinishao sells us improve plan thoroughly, the pattern that they use to us undertook making an on-the-spot investigation in the round with the analysis, help us achieve optimal production efficiency. " Leinishao is a client to offer on the base that uses all sorts of technology methods integratedly from beginning to end exclusive solution. " the case with respect to us, it involves traditional and cooling technology already, involve again along with form refrigeration technology, include the cooling fluid channel that traditional pattern machines already, include again use the modular core that adds material to make means machine, still involve the technology of solder of vacuum drill rod of modular core at the same time, " he complements, "Use all these technologies, we just can make a the most appropriate producer proposal. " carry this item, mr Hoffer harvested important knowledge and experience. "In the future, we can take seriously more in design phase shape cooling efficiency, " he says, "In Kärcher, cooling efficiency computation will become a mould to design medium key one annulus. Use these information, we can decide is use traditional and cooling program or follow form refrigeration plan. " " Leinishao provided perfect support for us. In this project, leinishao is our right choice; In the future, when we need a design to close outline temperature dominates program, believe it also can become our rightest partner, " Mr Hoffer is summed up.
