Can a pattern of compound plug-in unit that uses electroform to shape be you managing capital? Below the dominant of Japanese Motor Corporation, the manufacturer of the model that note model of world each district has begun to realise, the aluminium that has rate of tall heat conduction makes a pattern, it can shorten treatment is periodic, although the service life of this mould is briefer, but paying such price often is worthiness. Aluminium makes a mould be in by people more and more accept widely, but the die manufacturer that big to those requirements batch produces or those use intense and abrade characteristic resin (for example vitreous fill PVC) for the manufacturer that produces a pattern, put in the contradictory conflict with very big move. These die manufacturer came up against hard the difficult period of make a decision, on one hand they need to shorten produce periodic time, but the cost that needs to solve a mould to change ceaselessly on the other hand and content flow wait for a problem, because material pledges relative to softer aluminium patternmaking is provided,oxidize, the mutual contradiction between this two respects is coordinated very hard. When considering this one option, if be opposite the life that casts aluminous patternmaking to provide or reduce its to anticipate manufacturing cycle appears small error, can give die manufacturer cost even occasionally / the brings expect to be less than evenly result of benefit. Graph alloy of 1 this one nickel / red copper is compound shape in casting of electrify of semifinished product of a steeliness, via making its match each other after rough machining; Cool among them loop is what to milling treatment comes out is in directly on semifinished product (if pursue,medium blue part place is shown) still what another is worth to consider choose plan now, namely this mould both neither uses aluminous material to make, use traditional tool steeliness not completely also to build; The fast heat exchanger that use efficient heat exchanger however or uses patent technique to be made will cool mould. The article will be mixed to the service life of these moulds rate of value of periodic time expectation, heat conduction and its corresponding cooling passageway undertake discussing. Craft analysis is in this one process, it is how to avoid normally model the contradiction between antrum wall ply and rate of tall heat conduction. Mould antrum is a complex system actually, by model case of a of antrum wall itself very frivolous horniness nickel alloy is made, its the reverse side is You Chuntong those who make is thicker strengthen a layer. This one pure copper strengthens a layer direct with shed the cooling fluid contact via corresponding refrigeration passageway. Although nickel alloy crust has compared tool steel to have better heat conduction performance, but the pattern that uses this one craft to be made, its reached crucial action since the heat conduction efficiency that pure copper enhances a layer. The graph can assemble plug-in unit nickel what treatment of discharge of 2 classics EDM becomes with felt - cupreous answer is fit it is to use electroform to shape legal system becomes, this is a kind additional electroform deposit workmanship, have long history, apply technically at the production of the mould. On the electric axis that the metal is eletroplated to serve as pattern plate to, in order to achieve the goal that electroform shapes, depart its and pattern plate next. Below this kind of circumstance, nickel alloy layer is eletroplated to go up to electric axis directly, and will pure copper eletroplates over nickel alloy layer. The mould that electroform shapes antrum has advantageous heat conduction character, but this is not the issue with new what. Slimy model manufacturer, thermoplastic the model shapes make model business and rotate type die manufacturer noticed electroform shapes early the heat conduction of the mould leads an advantage, but in using part, type cools and shape with the electroform that cost effectiveness produces for the foundation the moulding that note model makes technology is a kind of noveller technology. Nextpage more than 10 years before, a few enterprises once had experimented similar electroform shapes compound mould antrum. Their train of thought is correct, had reached the sort of level, but they are to use method of drill rod solder, receive copper pipe solder electroform to shape on crust, establish corresponding cooling channel, this very shape like heat what die manufacturer once made in that way, next again above eletroplate more cupreous metals. This is a kind of speed slow labour force is concentrated model manufacturing technology. To make the plug-in unit of a mould can shape, the electroform that supportive formula carries on the back after using shapes modular pitch is occurring a few problems. Use composite material of polymer of appropriative metal stuff to make up for the skimpy share of plug-in unit commonly, the degree of Dan Jicheng result is very finite. Anyhow, this is a very complex process, be in economically not quite feasible. Graph 3 same two view below plug-in unit, showed cooling fluid enter, exit. Among them the circumstance of the cooling return that a view showed steeliness semifinished product is in-house with translucent means and this is contrary, this kind of new patent technology, use old famous degree of very low method, the reverse side is the same as a layer that shapes electroform regards an EDM as the electrode that discharge machines, on tool bloom treatment gives a corresponding recess. And undertake milling is machined directly on the cupreous material in tool steel and rolled steel interface and cooling channel is become. The mural layer that shapes as a result of electroform is opposite thinner, its itself as model the outline of antrum and change, the cooling passage that produces from this automatically with model antrum appearance keeps consistent. Next, electroform shapes be together with tool bloom felt (through a kind of among them means) , make this one component makes a whole, achieve requirement of finished product dimension. The mould plug-in unit that produces from this has very tall heat conduction character, its limits involves each all round model antrum, this is helpful for actually from model quantity of heat is absorbed on antrum wall. It founded to be in the mould with hot kinetic very advanced field. Although this one craft has very big advantage to Injection Molding, but it also is applied to make the model that blow model, thermoplastic shape model and colophony changeover model. By EDM discharge machines a machine tool to produce the pattern that craft creates, its dimension is restricted certainly. And use electroform to shape law can create large pattern, but this kind of method must want to be able to use EDM discharge to machine a machine tool on bloom directly. The plug-in unit size that this produces to its has an actual restriction -- the photograph of medium chamfer size that it must machine a machine tool to go up with EDM discharge suits. Those who use limits and benefit is affirmatory to job shops, whether is this one choose plan very well, need the actual condition according to every case, one by one undertakes evaluating. Electroform shapes because craft gets the limitation of geometrical dimension, not be very agree with each application domain. The deepness that goes up like the axis for example is salient machine with deep aperture, use electroform to shape the law is to be put in very big question. A lot of application domains but benefit from benefit from the hot dynamic benefit of these moulds, especially those were not made a way by 3D freedom the applied domain of very good service, in order to establish corresponding cooling condition. This one mould special agree with optics application domain, the production that resembles car illume lens or laser scanning illuminator for example is made. If this geometry appearance can use electroform successfully to shape,legal system is become, can forecast a problem to have cost around what reduce periodic time so / benefit analysis. This is the opportune opportune moment that software of mould refrigeration simulation proves its value. Use at present the most professional simulation software on the market is wrapped, what the compound mould model that makes an electroform likely shape and its tradition design is opposite should spare parts. Although its cast the cooling time of the result,the likelihood is not absolutely and accurate, but they should be to learn expect cooling time (periodic time) a poor very good guide. This periodic time is wrong, can use supportive computation some of specific moving project move reduce time. Managing / moving hour number is multiplied run cost hourly with should noting model compressor, can calculate the managing cost that gives every time to run place to anticipate. Let us see the case of a hypothesis now. For example: Manufacturer of a model that note model uses two model the mould of antrum. If he needs to make,produce 500 thousand parts, the cycle of run of the mould is 34s, so he produces these spare partses to need 14. The time of a week (press every 7 days week, everyday 24h job is calculated) . The operation cost that reassume notes model compressor now is 65 dollars / H, so produce this to approve a spare parts to will need to cost 153472 dollars. But, if use electroform to shape,compound mould undertakes more effective refrigeration, so these 10 mould pressing shapes the effect that rate can rise 5s (can shorten about the manufacturing cycle time of 15% ) , so finish inside the time that the manufacturing task of 500 thousand spare partses can not be in 12 weeks, its run cost to be 130903 dollars. Can be this die manufacturer so managing moving charge 22569 dollars. This is meant, even if use electroform to shape the mould need that compound plug-in unit creates costs 10000 dollars more, die manufacturer still can not be in inside 12 weeks time, call in these cost, plus weekly and additional managing 1000 dollars income. If he continues to run this one mould, so die manufacturer every other is returned 12 weeks but managing another 22569 dollars. More what is more,the rather that, because the refrigeration of its mould is more even, of the spare parts model variable quantity decreases, because this percent defective is likely lower. Express 1 it is the specific summary that makes to this example place. CNC Milling
