In fact, it is true South-East Asia companies offer low-cost finished products but they feature second-rate quality compared to the European standards, Italian wholesale Auto parts aluminum die casting Manufacturers first of all.

In order to contrast the threatening advance of these emerging markets, it is necessary to focus on weak aspects of the provided services and products.As anybody noticed, the European market was given a strong jerk by the pressing growth of new Asiatic economies (China and India above all), and in particular of the engineering and metal casting furnace.On this regard, 7 important metal foundries and cast iron foundy have set up a Group: a truly effective Team aimed to solve problems and needs related to the mold production and metal casting.

These are the companies settled in Veneto:• Procasting Srl: cast iron metal prototypes of any metal• Program 2000: design, creation and production projects• Modelleria Zuin: small and medium size models of metal, resin and wood for foundries• Modelleria Griggio: production of metal casting models for medium and big foundries• Modelleria 80: produces metal casting models and wooden moulds of big dimensions• Tecnomodelleria: small, medium, big wooden and aluminium models for thermal-modelling• Sand Form: cores: sampling and production for foundriesIt is easy to understand that this partnership is the Team’s main strength as it gathers in one spot the know-hows of 7 companies.Today the KnowHow Team offers the most innovative solutions to problems related to moulds design and moulds production for the industry.

In these conditions, the metal casting industry and mold-making industry have to turn to their experience, professionalism and ability to adapt to new market requests, all features that China and India can’t still provide for their new development. This union leads to some logical improvements as the cutting down on costs of prototypes and moulds production and on the replying time, whilst offering a wider range of technical solutions.

A Cupola is a type of furnace that is very much alike toblast furnace. The Cupola furnace is refractory lined, stack of steel that isaround 20 to 35 feet high. It rests on a base plate that is made of cast ironand has four legs. The casting that is obtained from the cupola furnace isknown as a cupola casting. Cupola Furnace:The Cupola furnace is one of the oldest forms of furnace that have beenused by the iron and metal foundries.

The Cupola furnace is the crudest and thesimplest furnace that has been used by the industries. However, the cupola’suse is declining and the furnace is fast being extinct. Merits of theCupola Furnace: Though the electric or the blast furnace has startedreplacing the Cupola Furnace, it has some special benefits of its own. TheCupola furnace can always remain continuously in action. The furnace alsooffers a very high melting rate. The China wholesale valve parts die casting most important merit of the furnace isthat it has relatively very low melting cost.

The furnace has also permits alot of ease of operation. However, due to the invention and development of theelectric furnace, the use of Cupola furnaces has substantially declined. Theelectric furnace melts a much larger amount of metal. The operation cost of theelectric furnace is also very low. The electric furnace also emits a muchsmaller level of smoke heat and also pollutants. Construction ofthe Cupola furnace: The Cupola furnace is constructed in a crude andsimple manner. The Cupola furnace is a vertical structure like a steel shell.The steel is lined with refractory bricks from the inside. The furnace has anopening half way in the vertical shaft. The charge is introduced through theopening. The charge is divided into different layers. It contains the metalthat is to be melted.

The metal is mixed with coke, fuel, and lime stone flux.The fuel is burnt directly into the air and is introduced in to the furnacethrough the tuyeres which are positioned above the hearth. The hot gases thathave been produced ascend and pre heat the charge. The cupolas in majority of the cases have drop down doors.The bottoms can be dropped down to facilitate the cleaning and the repairs. Atbottom in front of the furnace is a tap hole. The molten metal is removed fromthe tap hole. At the rear there is also another slag hole. The top of the stagis covered with a spark or fume arrester. Usually the cupola has a diameter of 405 to 2000 mm. It isoperated on varying fuels for different metal ratios. The molten metal that canbe produced in the copula of this size at a speed of 1 to 30 tones per hour. Continuity ofprocess: After the process of melting has ended, the charging is halted.However, the blast of hot air is always maintained till all the metal has beenmelted and has been taken out from the tap hole. When the air cools down, thedoors at the bottom are opened and the residue that has been left behind isremoved.

Lost Wax Casting is known as Cire Perdue in French. It is aprocess in which an artist’s sculpture is used to cast bronze. The Lost WaxCasting method is also known as Investment Casting in the modern industrial world. This is a veryancient method used for casting small bronze sculptures, but today it is usedto make many different artifacts and the process varies from foundry tofoundry. Today this developed method of Lost Wax Casting is used to makearticles like fine jewelery, show pieces, dental restoration, a few specificindustrial parts and also some machine tools.

Process of LostWax Casting: Rough Sculptormaking: A creative artist makes an original sculptor or mold or anartwork by using raw material like wax, plaster of Paris or clay. A mixture ofoil based clay and wax is preferred as these materials retain their softness. Final Mold Making:A mold is then made as per the original sculptor. The mold is made upof two pieces and a key with shim is placed between the two pieces duringconstruction so the mold can be put accurately back together. Molds aregenerally made using plaster or fiberglass or any other material that may besuitable. An inner mold of latex or vinyl or silicone is put pup preserve the detailsof the original art work.

Generally, the original art work made of plaster moldcracks and breaks during the initial phase of deconstruction. Many a times,numerable molds are required to get the exact replica of the original art work. Filling up themold: Once the latex and plaster mold is complete and finished, moltenwax is poured into the mold till it gets an even coating all around the mold.The thickness of the wax coating is around 1/8 inch. This process is thenrepeated until the desired thickness is achieved. Removal of waxreplica: The hollow wax replica of the original art work is thenremoved from the mold. The original mold can be used for making more waxreplicas, but due to the wear and tear of the original mold the reuse of themold is limited. Softening: Eachwax mold is then chased or softened using heated metal tools. The metal toolsare rubbed around portions that show cracks or the joining line of the mold,where the pieces have come together. Separately molded wax pieces are thenheated and attached. The finished mold is then dressed in order to hide anyimperfections.

The final piece then looks like a bronze sculpture. Making paths formolten bronze: It is also known as “spuring”, in short the wax copy isthen branched with treelike wax, so that the molten bronze reaches the rightparts and also it helps the air to escape. The critical and careful spuringbegins from the top of the wax copy. The top of the copy is attached to by waxcylinders to different points on the wax copy. Slurry, burnout, testing, pouring, release, metal-chasing,and painting are the final steps in China wholesale Auto parts aluminum die casting the process of Lost Wax Casting.
