The earth is a watery planet. Two thirds of the earth surface is ocean. The land is covered with lakes, rivers, and streams. The earth is like a sponge soaking up rain. Water collects in aquifers deep below and flows downward to join lakes and oceans. Human bodies range from about 60 to 80 percent water content. Water is the fluid that carries nourishment to living cells of organisms that depend upon it to sustain life.

Rain falls daily on the planet surface and is vaporized off the surfaces of the earth and its water bodies. Vapor is cooled in the atmosphere and collects in the clouds in tiny droplets. These clouds eventually become laden and release their droplets and rain that falls to the earth’s surface. The heating and cooling cycles of the earth function as a global distiller wherein the sun’s rays vaporize water later to be condensed and fall to earth as rain. Rain is distilled water, water that has been purified by vaporization and condensation. As rain drops, it picks up tiny particles and pathogens that hang in the air. On the earth rain water mingles with bacteria, chemicals, minerals, and pathogens in the earth’s oceans and land. This wonderfully pure distilled rain drop is progressively sullied on its return cycle to earth. The development of the industrial revolution has introduced many new toxins into the environment that end up in the earth’s soil and water bodies. That is why that despite the fact that water is ubiquitous many humans do not have access to safe and health drinking water.

Conceptually, die casting is a manufacturing process and requires articulate calculations to create the required outputs. This process injects liquid material into different molds to solidify the mold. The amalgamation results in different fabricated parts The primal benefit of casting process allows manufactures to create specific parts that are not economically feasible to create on the general assembly line. Million of parts that are made via die casting process could not have been achieved otherwise since the cost of producing certain items are not economical or even production possible.

any form of casting is a labor intensive process that requires a specific skill set. all processes from temperature building, quantity and quality of the liquid to be injected, form and shape of the mold, to the coolness technique of the output products all require specific skill sets. Without an accomplished team, it become very difficult for die casting manufactures to delivery quality products.

Die casting is a similar process in which molten metal is put under high pressure into the cavities of steel molds. The molds are called dies. The dies also come in different shapes and varieties in properties. Die casting process is heavily used in the automotive industry to create different body parts.

In many cases the inception of a new product idea begins with identifying the need for a product device or process that makes certain tasks easier. Some products are clearly more necessary than others for example, the scraper used to de-ice a car windshield is a very useful product, during the winter months and in parts of the world that experience freezing conditions. The point is that even great products can have only limited market potential. Before considering the development of a product for commercialization, the technology should be evaluated for its feasibility.

Software used in Engineering

As with all modern scientific and technological endeavors, computers, software and internet tools play an increasingly important role. As well as the typical business application software there are a number of computer aided applications specifically for engineering. Computers can be used to generate models of fundamental physical processes, which can be solved using numerical methods.

Summary

Rapid prototyping quickly verifies designs and reduces development time and cost. In today's rapidly changing marketplace, product development cycles have been compressed into weeks for what may have taken months or years in the past. Computer-Aided Design, or CAD, has revolutionized the way products are developed, and offers the designer a wide range of options to physically build parts and assemblies to validate form, fit and function. This article will discuss the use of CAD models in rapid prototyping to verify designs as it pertains to injection molding and die casting.

Summary

Since the 1940's, demand for high-volume, low-cost manufacturing has increased dramatically. One of the best ways to produce many parts that are dimensionally the same is through plastic injection-molding. And as advances in materials and mold making technology continue, injection molding will increasingly become the manufacturing choice. This article will discuss the application of injection molding for prototype validation and manufacturing.
