Terminology of Metal Stamping Die - 1

05/15/2014 15:26

Air hardened - A quenching method used to cool tool steel. Air or a vacuum cools the steel slowly.

Annealing – Heating steel and maintaining the temperature, then cooling gradually. This removes stress and hardness. It’s commonly performed to aide in forming.

Blank holder - A mechanism that prevents a blank from moving during the drawing process;

Blanking – Process to form, cut or punch out a rough shape of sheet metal; the resulting part is called a blank;

Bolster plate - A plate attached to the press bed that locates and holds the die shoe in place.

Case hardening – hardening to a pre-determined depth to improve wear resistance and strength for low carbon steel;

Clearance - The space between punch and die; proper die clearance is important to maintaining press speed, minimizing tool wear, and minimizing punch point galling;

Die Button - Also called a die bushing, is a tube or sleeve that makes the opening for a piercing punch. The slug passes through the die button.

Die retainer - A hardened steel block that contains the impressions or cavities that shape the part as the punch descends, and also holds the die button.

Die shoe - Also referred to as a die holder. A lower die shoe is the lower plate of a die set that supports the die retainer and die button. The upper die shoe is the upper plate of a die set that secures the punch retainer.

Flatness - A geometrical tolerance sometimes required, is measured as the distance between two parallel planes within which the entire surface of the part must lie. A flatness measurement determines the degree of variation in the surface of a part.

How to Choose the Best Solar Panel System for Home

03/21/2014 16:45

In this article, you can find out how to choose the best solar power system for home. Before going any further, you should know that the best solar systems are for residential home, whether you decide on off grid solar kit, off grid solar power systems and any other one, they should be very versatile and provide the most efficient service.

The new household solar power systems have become more popular than the traditional systems. This is because they can help you to save money on monthly power costs. Solar can also offer important backup during times when you have outages or if the main supply is off.

Figure out where to put the power system

When you are choosing a solar power system for home, it is important to think about the needs of everyone in the household. For instance, in most homes children will use more electricity on weekends. Some appliances will use more electricity than others will, so if you purchase a heater this could add to your monthly expenses. The solar generator systems significantly lower your energy bills simply by replacing the main power.

You might also use external power with garage tools, in the garden shed, hot tub and more. The complex connection lines is not really a good deal, so it is best to choose standalone systems if they are required. In case you are living in a rural or a remote area, you will have problems with regular power supply, so it is best to choose the solar systems.

Ask the right questions when you want to know how to choose the best solar power system.

It is important to allow some flexibility to get extra power generation when you need it. Several new appliances could make a big difference, for instance, if you get a larger fridge, new air condition unit or a new home theatre system. You can now soak for long hours in hot showers or spa without feeling guilty that you are running up the electricity bill. Solar power will help to improve your overall quality of life.

Getting the best prices and end results

Solar generation has become huge business worldwide, which means that the market is competitive and this will result in affordable prices. Therefore, you should check the different prices before making your final decisions. Look at the high quality systems first; these benchmark units will help you to choose the best solar panels.

German Researchers introduced New Method to Predict Solar Cell Module Life

03/21/2014 15:26

According to reports, the German researchers recently introduced a new method, which can more accurately predict the useful life of the solar cell module. Solar cell module material will be aging over long time if it is exposed in a complex environment. Although most solar modules manufacturers assure customers that the maximum life span of products is 25 years, but the general statement for the useful life is not accurate.

The subordinate Institute for Mechanics of Materials of German Fraunhof Association published communique, saying that snow load, temperature changes and wind load will cause mechanical pressure to the solar cell module, making the material contract and stretch, which will lead to material fatigue of solar modules over time. Among the materials of the solar cell module, the plastic back and the battery connector strip made of fine wire are especially vulnerable, which will break at some point like continuously bending a paper clip back and forth.

In order to clarify the influence of environmental factors on the battery module materials, the researchers measured the cell module effects by mechanical loading. They mounted the sensor on a complete solar cell module, and then measured the expansion and contraction degree of materials according to resistance changes of the modular solar panel system, thereby calculating the mechanical stress the cell module material withstand.

Researchers found by data evaluation that even a light breeze is enough to make the cell module oscillate, and the higher the ambient temperature, the more obvious this oscillation. In addition, ultraviolet radiation impact on materials fatigue is beyond the expected. Ultraviolet light causes synthetic material harder and more brittle, and the oscillation frequency will be increased over time.

Based on field measurements, the researchers set up a 3D simulation system. This digital simulation and analog system can infer the long-term impact of environmental factors on the cell module, and will produce what kind of mechanical pressure, so as to predict the life of the cell module. The researchers said that this combination of measurements and simulation methods can not only predict the service life of solar modules, but also can be used to improve the shape and material of cell modules.

IEA System-wide transformation needed for cost-effective integration of high levels of wind and solar

02/28/2014 16:59

The International Energy Agency (IEA, Paris) has released a report which finds that enough wind and solar to meet 45% of electrical demand can be integrated at a system cost only 15% higher over the long term, provided that measures are taken to transform the entire electrical system.

These measures include sufficient flexible generation and regional interconnection, more robust grids, power market improvements, and a better integrated and more responsive demand side. “The Power of Transformation” also finds that wind and solar work best together.

IEA stresses that the worst error is to concentrate variable renewable energy generation in one location far from load centers. In fact, the report's authors state that it is often better to look not at where the wind and solar resources are best, but where they maximize value to the system.

The report's cost modeling assumes current technology costs and a USD 30 per ton price on carbon. However, the price of emissions was a minor factor and IEA expects the cost of wind and solar generation to continue to decline. The agency also found that low shares of renewable energy can be integrated at little or no cost.

EPIA welcomes findings

The European Photovoltaic Industry Association (EPIA, Brussels), which is a member of the advisory stakeholders' board, welcomed the report's findings.

“This report rightly shows that the costs of renewable-based power systems can be minimized by adapting some planning and operational procedures”, said EPIA Policy Advisor Giorgia Concas. “This way, photovoltaics and wind would bring higher benefits to the system.”

EPIA notes that it fully agrees with the IEA conclusion that power systems with a greater degree of PV should feature short-term wholesale markets liquidity and allow for short-trading blocks. The organization also highlighted the report finding that balancing reserves do not need to be oversized if system operators adopt probabilistic calculation methods.

Need for flexibility greater in developing nations

“Power of Transformation” finds big differences in the process of system-wide transformation between developed nations with little growth in electricity demand and “dynamic” systems in developing nations where electricity demand is growing rapidly.

The report found that there is currently enough flexibility from existing assets in Europe, noting that the continent's pumped hydro resources are underutilized. However, IEA says that there is still not enough interconnection in Europe, citing a lack of capacity to export excess power from renewable generation from Spain to France as an example.

IEA found that in developing systems, flexible generation should be introduced hand-in-hand with variable renewables. The agency also found that planning tools in many nations are currently poor.

The Development and Deployment of Solar Power

02/28/2014 09:51

You may be familiar with recycle energy, but do you know solar power? Solar power is the conversion of sunlight into electricity, either directly using photovoltaics, or indirectly using concentrated solar power (CSP). Do you often use solar panels such as 500 watt solar panels? Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.

The early development of solar technologies starting in the 1860s was driven by an expectation that coal would soon become scarce. However, development of solar technologies stagnated in the early 20th century in the face of the increasing availability, economy, and utility of coal and petroleum. In 1974 it was estimated that only six private homes in all of North America were entirely heated or cooled by functional solar power systems—that’s the basic of today's off grid solar power system. The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world and brought renewed attention to developing solar technologies. Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the US (SERI, now NREL), Japan (NEDO), and Germany (Fraunhofer Institute for Solar Energy Systems ISE).

Between 1970 and 1983 photovoltaic installations grew rapidly, but falling oil prices in the early 1980s moderated the growth of PV from 1984 to 1996. Since 1997, PV development has accelerated due to supply issues with oil and natural gas, global warming concerns, and the improving economic position of PV relative to other energy technologies. Photovoltaic production growth has averaged 40% per year since 2000 and installed capacity reached 39.8 GW at the end of 2010, of them 17.4 GW in Germany. As of October 2011, the largest photovoltaic (PV) power plants in the world are the Sarnia Photovoltaic Power Plant (Canada, 97 MW), Montalto di Castro Photovoltaic Power Station (Italy, 84.2 MW) and Finsterwalde Solar Park (Germany, 80.7 MW).

Commercial concentrated solar power plants were first developed in the 1980s. The 354 MW SEGS CSP installation is the largest solar power plant in the world, located in the Mojave Desert of California. Other large CSP plants include the Solnova Solar Power Station (150 MW) and the Andasol solar power station (150 MW), both in Spain. The 250+ MW Agua Caliente Solar Project in the United States, and the 221 MW Charanka Solar Park in India, are the world's largest photovoltaic power stations.
