[Vulcan Engineering, mount, peter E, the 3 companies such as Macler Assoc] , casting a factory to high-tech should be what kind of condition has new consideration, core, modelling, fused to making, pouring and clear the working procedure such as finishing has a tentative idea, show a summary to try to introduce. The Vulcan that make core and Macler Assoc company think, in the present craft that make core, cast those who choose is main have Leng Xin box and shell core two kinds of methods. The research that makes core and development work most are in key of respect of law of cold core case is in hard fast and low-cost binder and the development of the machine that make core, still have the technique that makes high grade fuse. The way of cold core box that says here is the method of the sclerosis that blow air that uses ester of armour of amine, SO2, formic acid. Compare with housing law photograph, think fast cost of sclerosis of law of cold core case is low commonly, but Macler Assoc company thinks to answer the many sided such as the processing fee of litter of charge of cost of the price from the machine that make core and raw material, mould, operation cost cost, environmental protection, generation and sex of arenaceous second birth undertakes comparative delibrate. Be opposite especially each bits more undermentioned should pay close attention to more. 1. The dimension of fuse of Lv of take an examination, appearance and medium respect of cool one's heels, after undertaking comparative to cost, ability chooses finally. Especially shell core law, sincere or hollow pair of time that make core and have big effect with arenaceous quantity. 2. The method that make core is different, core box is different also. Laws of any cold core case do not heat, and housing law should heat. Consequently the material charge of core box wants petty gain than housing law (use for example woodiness, plastic, aluminous, cast-iron wait to be able to be used) , housing law must be used core case can be made in 425 ℃ . 3. As a result of Leng Xin the box need not heat, when need not beginning operation in that way like housing law, mix change time should be expended to heat when core box core box. 4. Law of cold core case is more advantageous is, the core with big dosage is arenaceous, can use machine or heat earths up means to undertake effective retexture, can decrease consequently deserted arenaceous, decrease new arenaceous, reduce cost. Although law of cold core case has adaptability good, sex of sclerotic fast, arenaceous second birth is good and the cost of unit weight is low advantage, but shell core law still is continueing to use, shell core law was not making the innovation of core machine and raw material respect and progress in that way like cold case law, but housing law is being used on have its clear advantage, for example cast surface quality is good, fall arenaceous performance is good, large the forked tongue of a snake has good operation strength less to wait with fuse with arenaceous quantity. Carry out shell core law not to need especially furnish and maintain mix arenaceous machine, aeriform generator discharges aeriform syringe to wait for equipment. Additional, in field of new the craft that make core, although already began to comment water-solubility affects good binder to the environment 5 years ago, mouat company also thinks to be used at production likely, but in economically did not get a proof. Make with animal sex material namely again some kind is stuck receive a dose, the need when using undertakes be transforminged greatly to making core machine or develop the new machine that make core. Stick newly receiving a dose is to use the water-solubility fuse of inorganic salt to stick receive a dose. Make stick the place when receiving a dose to use water, need to heat go dividing. But production fuse is easy dissolve at water, easily from core of the take out in cast, it is its advantage. This kind is stuck receiving an agent to be used at aluminous cast especially is very attractive. With commonly used stick receive a dose and take off core, when having difficulty, can consider to use. Modelling casts the modelling method that plant institute uses now, 10 years the technology had a without big change modelling to progress greatly in the past. Modelling, accurate to Shi Sha sand mold, disappear the model is cast narrate as follows respectively. Law of wet arenaceous model. Mount company thinks: Apply to major metal ability in the model law that qualitative, big batch produces, modelling of argillaceous Shi Sha is most model law of economy. Cast a factory to install the control equipment of stock latest technology, answer to be accomplished stage by stage, control a technology to be able to obtain first-rate property repeatedly with wet molding sand. These control equipment include, screening depart metal, time with arenaceous refrigeration, time with arenaceous when mixing practice accurate commentate quantity additive is waited a moment. Vulcan company thinks, machines and tools of present modelling of argillaceous Shi Sha has good performance, the career that can spend with never be being achieved 2 years ago, production requirement strict, tolerance is fastened very hour wet sand mold. Plus accurate control efficiency offers arenaceous unit high, make argillaceous wet sand mold is in iron radical alloy and the position that keep the most important in the modelling that is not ferroalloy. Macler Assoc thinks, in wet arenaceous modelling, perpendicular cent divide with the level model two kinds try to compare, medium, small-sized to big batch production, grey iron or ball iron cast a factory, heavy straight cent modelling is dominant, it is cheap, OK that because of its facility cost is compared high speed modelling, place needs staff the error that little, close fact spends is small wait for an advantage. But use perpendicular cent technology, on runner plan and prosperous mouth and configuration, and entering the respect such as core to be restricted with complex fuse, filter, Leng Tie, bushing, pestle. In addition, when good with fluidity alloy is cast, because the metal is static pressure ratio is higher, cause a metal easily to permeate stick arenaceous. Creating field of coloured alloy cast, already designed the big batch that suits cast of this kind of alloy to produce law of all sorts of characteristic and perpendicular cent model, show to be being popularized. But, have the cast of the physical characteristic of the requirement, using law of this kind of model to achieve quite before large quantities of quantities of height are produced, the producer type that regards big batch aluminium alloy as cast, metal mold casting still has an advantage. Macler Assoc thinks, horizontal cent Shi Sha casting, cast a factory to medium, small lot, still be one of advantageous model laws, no matter be to go up model, below model means, or match plate means, have adaptability to the production of complex cast. Can change inside a circular period about, short time moves, move for long to be able to have production effectively. But manual operation needs mechanization, produce the appearance to assure the cast with tall precision of admirable, dimension, still need to undertake transforming to equipment of a complete set of. The choice of law of lukewarm arenaceous model, need considers to nod each below: ◆ should have can the modelling device that modelling gives the high quality casting mould with even hardness. ◆ can change quickly pattern plate. Of the core below ◆ , casting mould assemble and unassemble mechanization. Macler Assoc speaks of, to make modelling is spent even, used a variety of technologies. Machine of a few kinds of automatic match plate was used shoot arenaceous with squeezing ramming law, right now, to obtain even casting mould density, shoot arenaceous with squeezing ramming law, right now, to obtain even casting mould density, if,shoot arenaceous way with board perpendicular direction. Still one kind goes up model, below model modelling machine, to make casting mould density even, still collected small brace up attack and squeezing ramming. Additional, to be filled to about arenaceous from time to tome strong wallop, useful also high pressure shrinks of gas. But, to get even casting mould hardness, used a variety of methods, will explain a kind of method to all sorts of modelling means cannot be solved. On the choice of modelling machine, want to cast a factory to undertake investigating to what use now, the appearance that uses oneself experiments, in order to observe its result. ◆ accurate sand mold the point of law of this kind of model is to use Leng Xin the chemical felt casting mould of case law. What Vulcan thinks this is aluminium alloy cylinder body and foundry technology of crock lid cast is renascent. Its reason is this kind of method, can be cylinder bushing casting in cylinder body, in the meantime, still have can use implementation directional the advantage of caky Leng Tie. This kind of method is to be in what era appeared 1970 to create cast of close clean look and the form is complex cast that cast pair of need to increase fuse with Shi Sha with Yu Zhu. Now, casting shaping form is complex when the accurate cast of dimension, standard method is to use method of modelling of cold core box. And, cast photograph comparing to apply to more alloy with sand mold. Arrive it is thus clear that in the exercise that make core, as a result of the innovation of colophony chemistry and model plant, can cast quality with lower price, higher component uses fluid pump and manipulator automatic product line, device is improved further, what need labour force to decrease, the cast of producible a high quality, low cost. The great changing that machine of molding of technology of Leng Xin box is the machine that make core. On some modelling machine model, below model at the same time modelling, the casting mould that some modelling machine can make a two sides pitch is folded model cast, the 3rd kind changes model it is to use machine of 2 groups of modelling, one group is to go up model, one group is built below model. These modelling machine to raise precision, make the flash of minute of molded lines the smallest, in casting mould of whole process lieutenant general close fact is its characteristic. Large model machine, use oil pressure drive completely to make its action flowing and credible. Of manipulator, carry out on coating, binder of next dry, core, besmear and combine the operation such as box. Because had these unit, can reduce requires labour force, assure top quality and manufacturing efficiency. Machine of modelling of box of this kind of cold core, the state of its casting mould affects cast surface not only quality and clear exercise, the position that makes with core head to be being assembled correctly of fuse molding sand is shooting condition of arenaceous head midstream to change is influential also, consequently, the design of casting mould is very important. Macler Assoc says, machine of modelling of cold core box has a few kinds to shoot arenaceous technology. Major modelling machine, the modelling machine of this kind of type, shoot with low-pressure large wind force arenaceous, can make shoot after every loop arenaceous. Have 2, 3 machinery plants are not to make sand shedding condition is changed, push a way with " however, shoot with what have patent design arenaceous, low tolerance high pressure is shot arenaceous, some machinery plants think, with push a way, when making complex casting mould, sand flows easily also. These 2 kinds of technologies, the appearance that had better use oneself undertakes try out is compared, single out best methodological " . Law of model of cold core box, can make the complex casting mould with very exact size, but what modular charge and molding sand stick the sand mold of cost specific humidity that receives agent, activator to use is arenaceous and stick the price that receives a dose to want tall, the modelling rate of law of model of cold core box is low. Disappear Vulcan of modular casting mould disappears because equipment and raw material change to develop somewhat then,the model is cast, adoption rate is expanding ceaselessly. Of much direction fill up the job is nodded, fill up arenaceous (sequel is arenaceous) fill up immediately etc new technology, make cast quality, model rate rises and cost is reduced. Disappear the advantage that the model casts has: Epispastic model can do not have rake or Tou is spent very small, still can spend with Tou sometimes make complex form OK modelling, there is freedom to spend on the design. In addition, can make cast weight is reduced, decrease not to need machining even, need not fuse also can be cast etc. The innovation on equipment, compositive component, coating, fill up the new development such as medium, make cast quality and manufacturing efficiency rise, make the market extends increasingly thereby.
