Hot Runner Technology

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. 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. Republic Services has plenty of information regarding this issue. 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.

Volga Federal District

High rates of the national project "Education" and the growth of consumption of the information required by educational institutions and require the development of the backbone transport network faster pace. The company "RTComm", part of the telecommunications holding "Synterra", was defined in 2007 by the Executive of the state contract for the national project "Education", under which 52 940 educational institutions in the country connected to the Internet. Performing this task in the Volga Federal District provides for construction of fiber-optic communication lines that pass through the territory of the Nizhny Novgorod region. One of these lines is FOCL "Nizhny Novgorod – Bor", which provides for the construction of a hidden passage through p. Volga. Tender for execution of the object was won trust "Svyazstroy-4" – the leading and largest company in the construction of communication facilities in the Volga Federal District. Specialists of JSC "Svyazstroy-4" were identified and agreed with the customer place the transition cable FOCL "Nizhny Novgorod – Bor" in p. Volga at 909.4 km (Atlas UGSS eq RF).

Coordinates lie in the transition area rowing canal in Nizhny Novgorod. The distance between the two sides of the natural channel of the Volga River in this area about 1400 meters (including approximately 100 m – width of the island Caves Sands), and with the artificial rowing canal overall width of a water hazard was 1750 m. The Professionals "Svyazstroy-4", which were made by developers and implementers of the project, it was clear that, given the performance technology company GNB Ditch Witch , available in the trust, so essential obstacle can be overcome only by a few steps.

Technology

Technology is constantly improving, the potential of technology is so high that it allows you to pour not only metals and alloys, but also composites, which have increased by several times (on Compared with simple alloys) of office properties, for example, tribological. These new alloy materials and technologies give significant reduction in metal consumption and production costs, which focuses on modern engineering. The practice of organized industries shows that the low material costs (consumption per 1 ton of suitable casting consists of four model-forming materials: quartz sand – 50 kg., antipenetration coverage – 25 kg., Styrofoam – 6 kg. and polyethylene film – 10 meters, does not apply to sand binder) save at least $ 100 per ton of casting, casting and placement of the entire volume of the container reduces consumption of the metal mixture at 150 … 250 lbs., electricity is 100 … 150 kW. am casting technology for penomodelyam has the following technical and economic indicators, compares favorably to the traditional sand casting flask form: coefficient of metal utilization 80-98% 65-80% yield increase in the mechanical properties of the material casts a 10-15% reduction in weight of castings in the 15-25% reduction in consumption of charge materials and alloys by 15-25% reduction in consumption molding and core materials at 80 -90% reduction in capital costs, decrease time 2-2.5 manufacturing facilities, labor costs decrease 3.4 times by 30-50% Effort finishing operations is reduced by 10 …

20% for single and 40 … 60 % at mass production. Particularly large savings in molding complex castings from the wear-resistant steel (screws for brick-making machines, beat, hammer mills and details), since greatly reduced the cost of machining.
