With more than 30 years customers` actual operation
and technology improvement, 1500mm two/three/five layers fully automatic
Stretch Film Machine is mature and cost-effective, some whole production line
adopt melt metering pump technology and high precision pressure sensor system,
which can stably and effective to control the pressure. It will highly improves
film horizontal and vertical`s tension strength and anti-puncture resistance
and make the film meeting the high requirement for machine packing film. The
cooling roller adopts big diameter design and special double-decker runner,
greatly improving the cooling effect of high-speed production to guarantee good
uniformity of cooling roll surface temperature. The film produced by this
machine has good shrinking memory function and self-sticky, which can be widely
used in wrapping of palletized goods. It`s good substitute for hot shrinking
packing film during transportation.

melt metering pump is more and more important in extrusion process, especially
in high-end products industries, such as high quality sheets, pipes, BOPP,
optical cable.
Installing the melt metering pump in the cast
stretch film unit, which can keep the production constantly and efficiency. The
pump can improve the product quality, stable the production and decrease the
energy consume.
The housing is made of chromium-nickel alloy or
nickel-base alloy, titanium alloy. The gear is made of quenching chromium
steel, other metal materials are also applicable. Bearing is made of graphite
NIAG, zirconium oxide or quench tool steel.
Advantages:
FAST AND STABLE FLOW SUPPLY
Eliminated the extruder`s pulsation wave. Improve
the product quality, decrease the defective rate, and decrease the waste, which
can save 2% material and 25% of the unit power consumption.
STABLE AND EFFICIENCY PRESSURE CONTROL
The melt pump can provide a stable pressure, which
short the discharge time obviously and make the production effectively.
INCREASE THE EXTRUDER OUTPUT AND THE MACHINE LIFE
It has been found that after install the melt pump,
the max pressure wave value is the pressure after pump. Which can make the
inner pressure of the extruder decrease, the melt shear strength decrease, the
temperature curve gently, and restrain the temperature rising. Also the melt
pump can avoid the damage to the extruder from the high pressure.

According to statistics, from January to April this year, the city's equipment manufacturing industry above designated size achieved a total value of 170.19 billion yuan, a year-on-year increase of 26.3%, accounting for 49.8% of the total industrial output value above designated size; the added value of equipment manufacturing above designated size was 41.32 billion yuan, an increase of 20%. , accounting for 48.8% of the above-scale industrial added value.
According to Liu Hequn, deputy director of the Shenyang City Economic and Information Technology Commission, Shenyang's equipment manufacturing industry has undergone strategic adjustment and identified the four major industries of machinery and equipment manufacturing, automotive and parts, aviation, and electronic information as key development priorities. New industrial system framework. Shenxi Industrial Corridor will be built into a new type of heavy chemical industrial base, the southern Fujian region will become the aviation manufacturing and high-tech industrial base, the Shenbei New Area will become the optoelectronic communications industry base, and the Dadong District will become the automotive and parts industrial base. At present, the construction of the three major gathering areas for mechanical equipment, automobiles, and aviation has achieved initial success.
At the same time, the development of a new backbone enterprise system began with the formation of Shenyang Machine Tool, Shenyang Blower, Northern Heavy Industry, TBEA Settlement, Yuanda, Sany Heavy Industry, North Transportation as the backbone, casting park, machine tool parts park, and power transmission and transformation facilities. The new mechanical equipment system based on the park; the new automobile industry system based on Brilliance Jinbei, Brilliance BMW, Shangtong Beisheng, Shenfei Hino, Zhongshun Automobile, Mitsubishi engine and Dongfeng engine auto parts cluster; The new civil aviation manufacturing system relied on aviation economic zone as the backbone of the aviation industry; the new communication industry system based on Dexin mobile phone, Xinyou communication, and Chenxun technology, relying on the optoelectronic information industry zone, and with Tsinghua. Tongfang and Fangda LED Green Lighting Industrial Park are emerging as the backbone of the new electronic information industry system. At present, key enterprises in the equipment manufacturing industry are performing well and their product orders are full.
According to Liu Hequn, the structural adjustment of Shenyang's equipment manufacturing industry has achieved remarkable results and has become the first pillar industry of Shenyang's industry. In 2010, Shenyang's equipment manufacturing industry completed a total industrial output value of 490.46 billion yuan, an increase of 25.6%, and its output value accounted for 51.1% of the city's total industrial output value, 3.2% higher than in 2009, and 4.8 times the 2005 GDP. The successful research of a number of major technical equipment such as UHV transformers, UHV switches, high-voltage bushings, multi-kilowatt KW nuclear power plant secondary pumps, heavy-duty gas turbines, etc., marked the goal of “independent Shenyang equipment and equipment Chinaâ€.
Shenyang's Equipment Manufacturing Industry Supports Rapid Growth and Supports Half of the Industry
Shenyang's equipment manufacturing industry has achieved high-speed growth in the industrial economy through the “structural adjustment, innovation, and development†and has propped up half of the industrial economy in Shenyang.
