1.0 Calculations 1.1 Sizing of component (including Shrinkage allowance) When cooling from molten state‚ all metals decrease in volume. When cold‚ casting will be smaller than their pattern. In order for parts to be of correct size‚ patterns are made larger to allow shrinkage. The extra size is called Shrinkage Allowance. Different metals have different Shrinkage Allowances. For the purpose of our project‚ we have been using Brass having shrinkage allowance of 1.5%. Length Nominal

metal objects is accomplished using a metal polish or tarnish remover; this is also called polishing. To prevent further unwanted oxidization‚ polished metal surfaces may be coated with wax‚ oil‚ or lacquer. This is of particular concern for copper alloy products such as brass and bronze.[4] |Contents | |[hide] | |1 Process | |1.1 Equipment | |2

As the world continues to modernize and reach new plateaus of technological and engineering successes‚ our urban areas are developing. More and more people are being packed into the densely populated cities that are popping up over both already developed and still-developing countries. With the rise of antibiotic-resistant bacteria and increases in contact with strangers met on the streets and in metro stations‚ the state of hygiene of a single individual is now more than ever having a direct impact

and sintered to small mechanical components. But this material contained pores at this time. After the war‚ various alloys were used as powder metal which enhances the properties of the final part. In parallel‚ the "atomize" technique was developed : a jet of metal was crushed into a mold. But this technique results in part still with pores. Moreover‚ it cannot be used for high-alloy metal. In the 1950s‚ the automotive industry used a lot of powder metal‚ especially the US market‚ followed by Europe

Rocks are mixtures of various minerals. Most minerals are lattice structures‚ both ionic and covalent. Economic minerals have been divided into two main categories: Metalliferous minerals- mined to extract a metal Industrial mineral- either has
