Molding Plastics Types

In injection molding it is important to take into account the specific properties of the polymer used in the manufacture of this product. The fact is that from its features depends type of items to be installed on equipment. It is particularly important in injection molding to choose the correct design of the screw – a device, which melts the polymer. In addition, the auger includes a piece lodged heated substance in the form below. Molding plastics uses various substances, which differ from each other viscosity, melting temperature and other characteristics. In order to facilitate the selection of the desired screw design, as well as other pieces of equipment, all polymers divided into three groups.

The first group includes those substances which are in injection molding smoothly change their physical state. In addition, they maintain viscosity over a wide temperature range, as well as demonstrate good performance of thermal stability. The latter means that the polymer used in injection molding, can long remain in the molten state without losing their basic properties. This includes such substances, such as polystyrene, polyethylene, polycarbonate and others. In general, casting plastics in their application does not require the creation of special conditions, it is easily and inexpensively. The second group of materials used in molding plastic, characterized in that the transition to a plastic condition is restored.

Because of this it is necessary to apply a special design screw, where the loading zone will be long, and the zone of mastication on the contrary, short-lived. This need to avoid getting unmelted pieces of matter in injection molding. Finally, the third group of polymers is characterized by low thermal stability. This means that in injection molding with the use of such substances should be as small as possible subject them to shear and bulk, as well as to comply with precise temperature control. You can use the special channels through which coolant is supplied or heated liquid. The first requires that, when molding plastics happened decomposition of thermally unstable polymers. The second – to keep them in a molten state.

The Plastic

We make comfortable us on the surrounding rocks and open the wetsuits… Steam rises and our breathing also results in a slight mist. On the photographs are taken, the people behind a veil of mist can be seen. I wonder whether the plastic barrels have kept most closely? Yes, the snack has remained dry and meal-giving the energy most welcome. Julian admonishes us to make to the zippers of the suits and he’s right, it’s amazing how fast it cools, if you’re still there.

Now I feel like tiredness is spreading through my body and the first feet fall hard after the break. The two leaders of the caves but praise us and say that we are good at the time. This is again a very close Ver fall point back down to the bed… During creep through, I feel the rock on the abdomen and back. This is me through my head that something korpulentere people here would have no chance to come through. When I express this, Johanna laughs and says that thickness it anyway not up here would create. The water in the narrow gorge is me further wading up to the chest and the cooling is pleasant. The crater range comes in the next 200 meters.

Kolks are something like deep troughs in the Creek bottom, out modeled by water falls and boulders as grinding. I make sure, if possible not in need, but to stay on top, to save power with great strides. After the slack, it is again very low, we have arrived at the so-called washboard. That is so because the water has completely smooth polished the rock floor and runs in small waves in. So back down onto his stomach and robben. I hope that we will soon arrive at the 2 siphon, our goal. But in between lies a longer Ver fall line, which is only in arduous climb.

Plastic Windows Need Repair

And then have to re-establish new window. So check out a few times as the company works on the market, the necessary documentation and so on. By themselves, plastic window is very strong and in most cases qualitatively made, but installers can put an end to such as by setting the wrong box. After that it was some time warp, loose leaf begin to close, harder to move and restore these problems can only specialist. And this again will cost a tidy sum. But in addition to quality installation should also fulfill the basic rules operation and maintenance of Proper use includes regular wiping windows from dust and dirt, lubrication special lubricants moving parts design, rubbing seals a special liquid to make the initial elastic properties If you feel that the window transmits air from outside, the case is likely to supplies and it needs adjusting, you will be able to perform professional representatives of such services.


The use of plastic cups no breach of style who is planning events or parties with many guests, is quickly faced with a logistical problem: the purchase of so many reservoirs for a one-off occasion blows the budget.
