This package meets the European quality standards. Credit: Sony-2011. Due to a combination of materials with different physical and chemical properties of the extrusion blow molding technology allow you to create multi-layered packaging materials under the specific product that meets the European quality standards (plastic jerry cans, jars, bottles); Feature technology allows the production of plastic packages, which has major advantages: low weight packaging, compared with the weight of the packed product, which allows logistics to deliver goods to the consumer to be more effective, low cost per unit of plastic packaging compared to other packaging materials. Reduced raw material costs weighed less a product – the less it costs. This is the most straightforward and an obvious dependence. However, it is clear that losing weight reduces the strength and the resulting capacity simply does not meet the requirements laid. Many years ago, extrusion blow molding machines are almost universally equipped with systems parizon control. These systems allow you to adjust the gap extrusion head on the fly from a given profile, and thus distributing the weight of the necessary parts of the product and cut it with useless sites achieved by optimization of weight. For capacities ranging from 1-liter gain in weight has always been, for any design of the bottle. Parizon control by vertical optimization of weight, because thickness profile is adjustable in the vertical products from the bottom up (or vice versa). We can facilitate (or heavier), for example, the lower part of the product, but could not do anything if you want to facilitate, for example, the sidewalls of the products for facial.
square. but in most cases do not meet safety, have a small share of work, a large mass and size, and energy-intensive inferior in almost all respects eloktronagrevateley with other insulators. If we consider that while they are still high cost, it makes them uncompetitive – see 'Ceramic Heaters – yesterday, industrial heating. " Electric heaters with ceramic insulators in the form of "dressing" spiraling to TSEs transfer heat heated object by conduction, have the maximum density heat flux of 15 W / cm. square.
but generally used for small objects, as in "daubing" spiraling to TSEs large diameter dramatically increases their size, weight and increasing energy consumption. Cost elektrogagrevateley with such great insulators. Electric heaters with insulators of mica materials transfer heat heated object by conduction, have the maximum density of the heat flow of up to 8,5 W / cm. square., of unlimited size of the object being heated, have high efficiency and low power consumption, long life operation and high reliability in the desired range of operating temperatures, can have high Ingress protection from the environment, small thickness, mass and thermal inertia, it is cheaper than electric heaters with ceramic insulators. However, the technical standard of electrical heaters is strongly dependent on the level of design and manufacturing technology. This is confirmed by the figures mentioned in the 'Map of the technical level. " As can be seen from the table, the maximum heat flux density in Depending on the supplier, ranging from 4 to below 8.5 W / cm.
