The ceramic molding process involves making a mold from refractory ceramic materials that can withstand high temperatures. To make the mold, a slurry of silica grains, ethyl silicate, water, alcohol and a gelling agent is poured around a pattern. The mold is then fired to harden it and burn off unwanted materials, producing microcracks that allow permeability and collapsibility. Once assembled, the mold can be preheated and used to cast molten metals. Compared to investment casting, ceramic molds provide similar surface finish and intricacy but with reduced machining needs, shorter lead times, and ability to cast at various sizes and metals.

Slush Casting is a traditional method of permanent mold casting process, where the molten metal is not allowed to completely solidify in the mold. When the desired thickness in obtained, the remaining molten metal in poured out. Slush casting method is an effective technique to cast hollow items like decorative pieces, components, ornaments, etc.
APPLICATIONS
Some casting of pewter is cast using slush casting method. Using pewter and other metals mainly hollow products are casted. Decorative and ornamental objects that are casted are as vase, bowls, candlesticks, lamps, statues, jewelery, animal miniatures, various collectibles etc. Small objects and components for industry like tankard handle, handles for hollow wares, etc.
ADVANTAGES
Slush casting is used to produce hollow parts without the use of cores
The desired thickness can be achieved by pouring our the left over molten metal
A variety of exquisitely designed casting can be casted for decorative and ornamental purpose.

Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.

Manufacturing is the production of products for use or sale using labour and machines, tools, chemical and biological processing, or formulation, and is the essence of secondary industry. The term may refer to a range of human activity, from handicraft to high-tech, but is most commonly applied to industrial design, in which raw materials from primary industry are transformed into finished goods on a large scale. Such finished goods may be sold to other manufacturers for the production of other more complex products or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).
Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product. The manufacturing process begins with the product design, and materials specification from which the product is made. These materials are then modified through manufacturing processes to become the required part.
The manufacturing sector is closely connected with engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Cast Parts. Examples in Europe include Volkswagen Group, Siemens, FCA and Michelin. Examples in Asia include Toyota, Yamaha, Panasonic, LG, Samsung and Tata Motors.
Here in this post, we have to list 6 processes of aluminum castings. The aluminum oxide layer that forms instantly behind the work is removed from the mold and provides a barrier against corrosion.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
2. INTRODUCTION
Ceramic molding has been around for centuries.
Ceramic molding is an offshoot of the investment-
molding process but can cast materials at much
higher temperatures.
Ceramic casting uses refractory ceramics for mold
material.
3. THE PROCESS
Silica grains plus ethyl silicate, water, alcohol and a
gelling agent such as HCL are used.
Slurry is poured around the pattern.
Allowed to gel in about 4 to 7 minutes.
Pattern is then removed.
Mold is fired by igniting the alcohol.
Firing will burn off any unwanted material and make
the mold hardened and rigid.
4. Firing of the mold produces a network of
microscopic cracks(microcrazing) in the mold
material.
These cracks give the ceramic mold both good
permeability and collapsibility for the metal casting
process.
5.
6. Once prepared, the two halves of the mold are
assembled for the pouring of the metal casting.
Often, the ceramic mold will be preheated prior to
pouring the molten metal.
The metal casting is poured, and let solidify.
Like in other expendable mold processes, the
ceramic mold is destroyed in the removal of the
metal casting.
7. PROPERTIES AND CONSIDERATIONS
It can produce parts with thin sections.
Excellent surface finish, and high dimensional
accuracy.
Eliminates the need for machining.
Can be used to manufacture ferrous and other high
melting point metal casting materials because can
withstand extremely elevated temperatures.
Relatively expensive.
Long preparation time of the mold.
8. FEATURES
Tolerances: 0.4 %.
Surface finish: 2 - 4 µm.
Wall thickness: may be as small as 1.25 mm.
Weights: Range from 60 gm to 1000kg.
Draft allowance: 1° recommended.
Patterns: Reusable and cheap.
Casting size: generally not restricted.
