Structural details of specific parts of the mold. The mold consists of a large number of items that should just be connected to each other. Details mold is divided into normalized and special. Construction of normalized components of the mold can be set in advance, regardless of the design features of cast products in the mold. Recently Nicolas Keller sought to clarify these questions. Any mold in 50-95% consists of standard on the range and weight of components (normal). These details and costs range from 10 to 60% of its full value.

Fluctuations in interest depend on the design of molds, casting geometry and tool requirements production and the level of preparedness of the designer (design company) of the mold, its desires and opportunities to apply the appropriate standard items. The solution of the same technical problem in the design of the mold is almost always structurally invariant with gnezdnosti by gating system, the system of pushing, etc. To normalize the details of the mold include: Upper and lower plates of the mold; common plates, machined on all sides, suitable for the manufacture of punches, dies and shaping boards that require a large sample size; Details to mold – For guides and speakers, the Centre elements, retainers, including inserts calendars, springs, etc.); pushers and the elements to extract details from the form – Items removed from the form, double stroke Shanks, pushers of O1mm x 200mm with a thickness of tubular pushrods wall of 0.75 mm. Gap of 0.8 mm. Bearings, gears; Injection system, – bushing, hot runner injectors (nozzles), including injectors multipoint fuel injection, hot runner manifolds, filters; Control technology – heating elements, connectors, control devices and sensors, portable instrumentation; Cooling System – The connections, including stainless. . David Treadwell understands that this is vital information.

The best technology end of the 20th century, improving, stayut firmly on an industrial basis, provide income and attract investment in new production, determining its competitiveness. Metallurgical processing of metals and Foundry post-Soviet space have a long tradition and solid engineering experience. Russia and Ukraine at the end of the second millennium is a leader in the production of metal castings and per capita population. Now casting production decreased by several times. Are rare scientific and technical institutions, which have retained engineering achievements, experience in implementation of competitive technologies, from design and manufacture of foundry equipment prior to delivery of home equipment to the customer with a turnkey implementation of the commissioning and development of the technology in production.

Among developed in recent decades technology in the foundry business is gaining popularity convenient technology, where a model casting means already half a casting itself. Model castings are made from expanded polystyrene, commonly called the most foam. It turns out, such as packaging of a TV, or single food dish, which have become part of our everyday life, their stamp on millions of machines and plates of polystyrene insulated exterior walls of high-rise buildings. Expanded polystyrene is to hard foams (such as bread, for example), which in physical chemistry is defined as the dispersion of gas in a solid, or more precisely, the cell-film dispersion system. In our case, the matrix is polystyrene and dispersed ("crushed" and "scattered") gas. On a similar technology (as in the production of packaging) for a series of casting models produce blowing powdered polystyrene in lightweight aluminum mold (very simple to manufacture and often multi-seat), followed by foaming and bonding of granules during the heating of molds up to 1200 C.

Furnish heating system has its own set of nuances. As is well known heating pipes pass through floors and intercommunication, of course, require a thermal gap between the pipe and flooring. Quite Naturally, the desire to make this gap aesthetically beautiful. But as you close the heating pipes on their own, without professional help? Let's try to answer as fully as possible on this vopros.Itak usually parquet used in two ways. We consider both, but some of them more than you, then choose samostoyatelno.Oformlenie heating pipes using plintusa.Pervy option offers conceal pipes or heating supply an elastic material, and then, to gloss over all the cracks of cement mortar. This material may serve as asbestos board, which is as tightly, leaving no gaps wound on the tube.

The height of such winding must be equal to the level of plintusa.Dalee to hide the pipe directly to the skirting. For this pipe obkladyvaetsya soundproofing gasket and the remaining space between the baseboard and the heat pipe filled with cement-sand mortar. Dove solution to dry and harden well, you can paint the surface in the desired color, the right or vice versa with a contrasting color of floor pokrytiya.Oformlenie heating pipes with rozetki.Vtoroy version of this tube is much easier to hide. To fill the gap between the thermal parquet floors and a pipe heating system uses heat-resistant elastic sealant. A coupling between the pipe and the floor is made rozetkoy.Rozetka can be both wooden and plastic, which has a very simple build system – samozaschelkivayuschiesya spikes.

Wooden socket consists of two parts, and so-called fixing system "groove-joint". If you decide to use just such an outlet, it is necessary from the base, spines and grooves glue (it may even be ordinary PVA, although it is best to use Universal waterproof glue). Give him a little, just 2-3 minutes to dry out and join the two halves of sockets, with the "surrounding" the tube, and tightly clutching their one another and to the surface of a floor pokrytiya.Ne Remember to immediately remove the glue speaking. Wooden plug as well as plastic can choose the color or paint over, is still possible to use an appropriate stain color, and then open it lakom.My told how to hide the pipes and make the interior of the apartment harmony. Which option is better – it's up to you.

In the horizontal system heating can not be fully warm all the rooms of the house. The heating system runs with your hands natural circulation, since this is sufficient circulating pressure. Since the stack of these building has a height of not less than 10 m, the boilers can run on any fuel. Recommendations on installation and operation of water heating In conclusion, some recommendations for compliance of building regulations, which should be taken into account during installation, adjustment and operation of heating systems, made by hand. Equipment with firing furnaces (boilers, ready to heat registers, stoves) should be installed under the rules of fire safety, providing for the installation of these devices at some distance from building structures. For example, a distance of ceramic pockets of fire (stoves, fireplaces, boilers) should not be less than 100 mm – up to fire-resistant, 150 mm – up to inflammable and 250 mm – up to combustible construction. Chimneys should be placed so that the firing plant (boilers, furnaces, etc.) can be placed in close proximity to the chimney, as long chimneys reduce cravings.

Chimney height and diameter are accepted depending on the type of heating system and fuel used. Solid and liquid fuels warehoused near the boiler in compliance with fire safety rules. With commissioning of water heating system check the conformity of its design and technical specifications, the correctness of installation pipelines, installation of heating appliances and fixtures, the location of a culvert units, the lack of leaks in pipe joints, valves and fittings, the strength of attachment of pipelines and equipment, serviceability of the valves, the uniformity of heating of all the devices in the building.
