Solar thermal energy is a technology for harnessing solar energy for thermal energy and it is different from photovoltaics, which convert solar energy directly into electricity. There are many applications of solar thermal energy such as drying, heating and water distillation. Many solar thermal technologies have existed for centuries and have established manufacturing bases in many sun-rich countries. Manufacturing can be done on a small scale without using expensive equipment. In 2008 solar thermal energy industry in Europe has grown over 60%. http://energysourcefacts.org/solar_energy_solar_thermal_energy.html

CAD data or Computer Aided Design data simply refers to the electronic file information created and used by various CAD / CAM programs for the design and manufacture of certain types of mechanical and plastic injection molded products. For the purposes of this discussion there will be two main types of data which will be addressed. The first type of data is called "native" data which simply means the electronic file information created, saved and retrieved or maintained within the authoring CAD program. http://www.cadmodels.biz/3d_cad_file_repair_and_cleanup.html

Two dimensional (2D) CAD (computer-aided-design) models enabled drawing quality improvements in product design and engineering over manual drafting. Prior to the advent of economical desktop computers skilled draftsmen spent hours laboring with graphite lead pencils on velum and Mylar to achieve engineering quality documentation for fabrication and production manufacturing. The process required tedious checking to eliminate errors wherein modification required erasures and redrawing over and over on the same sheet. Large projects had many drawing documents linked to one another that required procedural revisions and archiving. http://www.cadmodels.biz/2d_cad_modeling_and_2d_cad_drawings.html

Injection molding of plastics is one of the most cost effective processes for manufacture of parts in volume. While mold costs can be significant, amortization over many parts can make the overall cost of injection molding highly competitive with other manufacturing processes. The wide range of available polymers multiplied by the huge array of specific blends offer a tremendous range of physical, thermal, electrical, and chemical properties. Engineering plastics, classified by mechanical properties such as stiffness, toughness, and low creep, increasingly replace metals on a cost and performance evaluation. http://www.cadmodels.biz/3d_cad_design_for_injection_molded_plastics.html

Due to the many rare properties of silicone, such as its thermal stability, flexibility, low chemical reactivity and low toxicity, excellent gas permeability (over 400 times that of typical rubber at room temperature), good electrical insulation and the fact that silicone has a high ability for repelling water and other liquids, makes it an extremely useful material in many industries, especially food and medical. http://protosil.net/mats/food_and_medical_silicone_grades.html

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. http://advantagetooling.com/rapid_prototyping.html

Stamping dies are tooling devices which are used for cutting and forming metal into desired shapes as well as in cutting and forming desired shapes into metal. Dies are generally two mating components which are necessary in order for sheet metal to be pressed or stamped. http://advantagetool.us/mats/progressive_and_stage_stamping/

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. http://advantagetooling.com/stereolithography.html
