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.

Moire, a touch of that beautiful image. Moore, the photographer's nightmare, whether you are a photography white or a photography veteran.
Moiré phenomenon is a kind of visual phenomenon in which the interference fringes (commonly called water ripples) occur in the camera lens facing an object with a certain interval, especially when photographed against an array of light bodies. 
Shenzhen Tongpu Technology Co., Ltd. (.cn) launched a grand elimination of moiré optical screens that can easily solve the problem of moiré. The anti-mold-pattern optical screen, through the multilayer optical structure and the micro-filter crystal, enters the light guide of the LED pixel light spot, refracts and disperses the light, thereby changing the optical gap of the LED lamp interval, and eliminating the moiré appearance in the camera picture. This project has won national technical patents. Whether it is a moving image or a static image, the most consistent color can be maintained.
Assembled anti-Moore optical screen to improve the true color reproduction of LED video wall, took the problem of seaming of the original DLP projection box, color deviation, high cost of use, opened a seamless large screen, no color deviation, use A new chapter with a very low cost. After assembly, the thin optical screen not only completely removes the moiré, but also increases the contrast. It also plays an anti-static and protective role, eliminating the graininess of the LED and making the LED screen feel like a flat LCD.
This Moore-proof optical screen is mainly applied to the TV studio background wall and the photographic background display wall. It has so far been applied in a large number of projects in foreign countries, domestic CCTV, provincial TV stations, and local TV studios.
Presumably many of my friends are having trouble shooting screen objects such as TVs, monitors, mobile screens, tablet screens, etc.: Obviously looking at a very clear screen, but after photographing it with a camera, it actually shows The ripples in a circle, which affects the color and clarity of the screen, are also very unattractive. The ripples that appear during the filming process are scientifically called moire.
