http://ecoskimple.org/de/?q=Rolf-Albern-Biomass-Energy - Biomass is biological material derived from living, or recently living organisms, like alcohol fuels, waste, and wood. It is a renewable energy source because the energy it contains comes from the sun. Biomass is the oldest source of renewable energy known to humans and supplies almost 15 times as much energy in the United States as wind and solar power combined. Biomass energy has been used since people began burning wood to cook food and keep warm.

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.

2D versus 3D CAD

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.

Stereolithography, or STL, is an additive technology which uses a UV laser to create parts from a UV curable liquid within an SLA, or Stereolithography Apparatus, system.

For a part to be created using STL, a 3D model of the desired part must first be created, after which the 3D data is seperated into a group of 2d layers of the entire part. These layers typically range from 0.10mm to 0.050mm in thickness (although a resolution of 0.050mm in thickness is usually used) and this group layers is called called "slice data." The slice data is then fed into the SLA system and the actual fabrication process begins. The platform is first lowered into the vat of clear, liquid plastic photopolymer. The polymer used is sensitive to ultraviolet light, allowing the polymer to solidify when it is exposed to the light provided by the UV laser and the materials used in this process range from soft durable plastic to hard plastics. The ultraviolet laser traces and selectively solidifies the first layer within the resin onto the platform, which is currently submerged one layer under the resin.

After the first layer has been created, the following layers are added to the first layer while adhering to the previous layer. A resin-filled "re-coater" blade is swept across the top the previous layer removing the uncured polymer while re-coating it with fresh material. The platform is then lowered gradually submerging the platform along with the base of the part (and the part itself, or rather the section of the part, which has been already created layer by layer) deeper under the resin. This process repeats itself until the last layer has been created and the part is completed. This is a relatively quick process. Up to about two minutes is needed for each layer to be created whereas an entire run might take six to 12 hours.
