Shvertbota are made by method of vacuum infusion.
Material composite. We have the best goods, qualitative, especially strong, take from us you will not regret. Formation with application of vacuum is used when it is necessary to create the mechanical pressure upon a product during a cycle of its production. Using such process, it is possible to make a product of the superior quality, in particular products of carbon fabrics. Let's consider technology of vacuum infusion, and also its advantage and shortcomings before manual formation.
If at the created product there is an excess pitch, then the detail will have more properties of pitch (fragility), it is bad. For example, the content of pitch in a product prepared exceeds 100% of weight of fabric on the relation to pitch. While strong materials which are applied to the space purposes contain only 40% of pitch. It allows to maximize physical properties of materials, such as carbon fabrics, receiving good strength characteristics to weight.
"To wring out" surplus of pitch in house conditions, use a way of vacuum formation with application of a vacuum bag. Such method with allows to achieve result in 50 - 60% of the contents of pitch in a finished product that is very even not bad.
In difference from an industrial method where for achievement of high efficiency autoclaves are used (lift temperature and pressure 2 - 3atm), vacuum formation in house conditions puts pressure equal to one atmosphere. How it occurs?
When the vacuum bag, pressure from one and other party of a bag is established to equally atmospheric pressure. For creation of vacuum from a bag air is pumped out. Pressure in a bag becomes negative, and atmospheric pressure outside remains the same. This differential of pressure provides the uniform mechanical force of a clip which squeezes out excess pitch and air. Some kind of press turns out.
