Dimensional stability of the model, lack of a connector shape and consistency of process parameters allow you to be precision castings so as to exceed the precision castings of LPM. In the mold cavity filled with expanded polystyrene, can not get foreign inclusions, which provides fewer blockages. By roughness surface defined in many ways the surface roughness forms, castings castings to meet the LPM. The reason is that in both cases, refractory paint or coating is applied to a model, not the surface form. High quality castings LGM allows for efficient use of the process in the manufacture of castings, which are traditionally manufactured LPM.
The definite advantage to the LGM LPM – the simplicity of its implementation. Practically eliminated or reduced to a minimum coating operations, forming, annealing forms a knockout and cleaning castings. The use of FF instead of LPM reduces consumption of expensive mold materials up to 10 roses Power – 2 – 3 times and labor – 3 – 4 times. For example, the technology of the pump impeller of high alloy by LGM provides such technological parameters of the model of EPS consists of two parts the basic model and the disk cover and their subsequent bonding. This allows you to perform any configuration of the blades of the wheel and avoid the variation in. Other methods of forming, in including LPM and plug shape using a rod, do not provide quality castings. In the manufacture of cast model requires the use of water-soluble cores, because the mold inserts interscapulum can not be performed.
The assembly of rods (even in jig) does not provide ravnostennosti blades in the model. In addition, high-quality coating in interscapulum difficult that leads to defects in castings trudnoispravimym. Consequence of the use of detachable forms a rod – variation in wall thickness of blades and inlets between the rods, whose removal is problematic. Thus, the casting on gasified models to date – the most promising technological process of manufacturing castings weighing from 0.1 to 5 000 kg. instead of well-known classical technologies to produce precision castings. Especially effective is its use in casting slozhnokonstruktsionnyh castings of various alloys.
Let’s take a look at the basics.If you want to start a recording studio, there are a few important things you need to know.We are going to cover in this brief article. Firstly, you must have an idea of why you want to start this business.Why owning a recording studio?What does so attractive for you?There are many different reasons.Some people want the money produced a study, others want to have salsa or rock star in the study and several more reasons.Perhaps a combination of these things. Whatever your reason for initiating a recording studio, you need to know with accuracy because you want it to do. Then determine your strengths and weaknesses.Not just for you but also for your study.Take a good look at the total package that his Studio has to offer. What can I offer to any band or group?Demos Basic, only 4 tracks of mixtures, a Full album’s 12 tracks?Whatever it is, be honest with yourself.Groups have different needs, and if you have a study of low level which can only be cut demos still rough customers can find!It is not difficult.Only he understands exactly what you have to offer in the market.
Now that you have a purpose that guide you, you know what his Studio are capable of doing, it is time to think about marketing.This is really all about reaching potential customers.Who are your potential customers?Think of it.What kind of bands or artists buscarian a study like yours?Once you know who are your customers, you have to find out where to find them. If you want to reach out to high school bands, they need a quick demonstration, then reaches them.You can talk to teens in her neighborhood, and ask if they know of any band.Or you can sponsor a local talent contest. This technique has worked well in the past.Just find your potential customers and go for them.Let them know about your study.
Topic has naming: the work is replaced by electric motor muscles. It would like to tell about this new and innovative development of scientists, as an artificial electrical muscle. Those who are familiar with electrician and the basics of electricity, is well aware of the basic ways of converting electrical energy into mechanical motion. This is, first of all, electric motors of various types, principles of operation, type of power, etc. They have, by passing electric current through the inner windings, formed the electromagnetic fields to repel each other, thereby causing the rotation of moving parts. Such movements have rotational in nature, which often requires additional mechanisms for the conversion of translational. At the same time lost some of the energy, increasing energy costs.
Even the motors because of their construction and operating principle of efficiency is not ideal. There is another way to make forward movements by means of the same magnetic field. This is a retraction or repulsion in the electromagnet core. Disadvantages is also not ideal efficiency and the difficulty of a precise control of the action. Now let's see what can be replaced by an electromagnet and electric motor work in our time. This is an analogue human muscle, which runs on the same principle. As you should know from the lessons of biology, upon the momentum of the human nervous system to its muscles, there is a reduction of protein fibers. This eventually leads to simple muscle contractions (reduced length) and carry out some physical work.
This principle is very simple. But due to the fact that scientists are a long time could not create such an artificial material that would repeat the work of human muscles, this idea was in place and had no further development. In 2007, scientists from the University of North Carolina, announced that they have managed to create such an electrically conductive polymer on based on carbon nanotubes.
