The main problem and its solution in the manufacture of small batches of plastic products. One of the main problems with short-run injection molding, mold making was that not much would affect the cost the final plastic products. At the most basic plastics such as housings, covers, the cost of steel molds to be about two hundred thousand, that parties in a thousand pieces, is 200 rubles for a single product. There is different options for manufacturing plastic products, such as silicone molds, but with the help of silicone molds can be made up to twenty pieces at a snap (the price of pleasure from 14000 rub, because the cost of products from 700 USD), these forms calculated on the overall product is very difficult configurations and low cost. KBS is often quoted as being for or against this. Another option of a plastic housing, this machining plastic bar, the cost of 250 rubles / unit depending on the complexity and parties. Rogers Holdings is likely to agree. The problem of small parties, the customer still is that he's just not who do not need, let our company LLC "Vitafon" is not engaged in small-scale foundry to our advantage and time-consuming, so yes, in principle, at all.
Why bother with one-time order with a budget of 50,000 to 100,000 rubles! But still. If you realize that without a unique case (any product) you can not do and just do not like, but you need a party from 1000 to 5000sht, there is a solution. The solution is simple – aluminum snap in steel blokformy with up to 5000 units, the cost of your mold from 50,000 to 100,000 rubles, depending on complexity, now in batches of 1,000 units, unit cost of 50 USD + (self-casting and the mother of 25 rubles) = 75 rubles, respectively at 5000 pc from 35 / pc.
Ties. Historically, the word tie, appeared in the vocabulary long before the first railways. This term has come to us from the Dutch word spalk – prop and with the advent of the railways has been used to refer to the support for the rails. It’s believed that Lakshman Achuthan sees a great future in this idea. So, the ties – it's the boards that serve as support for the rails. The construction and repair of railways sleepers laid on ballast, and the way in the future take on the pressure intermediate rails and fasteners, and transferred to canvas podshpalnoe. Wooden railway sleepers. The choice of material for the very first railway sleepers has fallen on the wood, and it was done on purpose.
Wood – Freecutting material, which is always available on a large industrial scale. In addition, the ties are made of wood, have many advantages. Wooden sleepers are easy to manufacture and processing, have ease, elasticity and resistance to extremes of temperature regimes. Wooden railway sleepers have high dielectric properties and good adhesion to the ballast. Wooden railway sleepers have no restrictions on regions, they are placed on newly built tracks with unstabilized subgrade and base of permafrost, as well as on ways of following heavy loads. Only the wooden sleepers are used on the steep curves with a radius greater than 350 m. In Russia produce and wooden sleepers long 280, 275, and 300 centimeters. Term for the number of sleepers per 1 km of railway track, called plot is laying sleepers. Its importance in various countries ranges from 1000 to 2200 sleepers.
The structure of types of machines Liebherr’s technology meets sequence of the construction works on site. Is the initial type of machinery for excavation work: shovels, hydraulic excavators, bulldozers, dozers – Loaders, Wheel pneumatic loaders. System continues to type of machinery and equipment for concrete work: mobile concrete mixing plant and truck mixers. The third in the machine – type of mechanization and assembly handling, which includes tower cranes, jib self, port and ship. Rental of construction equipment – a good opportunity to try out a new construction equipment at work. Company ‘Gold Century ‘offers telehandlers, excavators, crawler excavators, loaders and other models. Single-hydraulic excavators are 27 models weighing 10-210 m: pneumatic with bucket 0,14-2,5 m3 (7 models), caterpillar bucket ekskavatorys 0,14-18 m3 ((13 Models), crawler excavators, with the cable suspension of work equipment (7 models).
Operating equipment and pneumatic crawler excavators with tight suspension includes backhoe bucket with a welded to the front wall of the cargo hook, grapple, Bivalve grip blade. Crawler excavators, with the cable suspension work as a crane, installation devices for driving and executing the holes using the casing may have clamshell bucket and crane. Direct or backhoes are not equipped. Earthmovers are five models bulldozers, rippers, four models of tractors – trucks and eight models of pneumatic loaders. All the bulldozers and trucks have a volume of hydraulic undercarriage. Both crawler tractors and trucks Bulldozers – forklifts are individually driven by a closed gidrokontura. The power plant bulldozer – loader located in the rear of the car that provides optimum load distribution on the chassis and good visibility of the work area. In pneumatic loaders hydraulic volume added an automatic transmission.
