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.

The advantages of the uncap centrifuge and the ordinary centrifuge are that: (1) The cover of the vacuum blood collection tube is automatically taken off during the centrifugation to improve work efficiency.
(2) Instead of manual capping, preventative reagents come in contact with the body.
Installation Precautions (1) The table surface must be solid and flat to prevent the capping centrifuge from generating vibration or moving the instrument during operation.
(2) The power supply has an independent grounding line. It is forbidden to share the neutral wire with the ground wire to prevent electric shock.
(3) There should be no corrosive gas and electromagnetic field interference around the capping centrifuge to prevent premature failure of the protective layer of the instrument and interference with electrical components.
(4) The level of the cap-free centrifuge is set to ensure uniform force on the four rubber feet.
Using the Code 1. Uncap centrifuge After removing the rotor from the end of centrifugation, place it on the test bench, dry the remaining water in the chamber, and leave the centrifuge lid open.
2. Turn the lid on the platform of the centrifuge, or place it on the test bench. Do not tighten the float on the rotating head. Because once it is started, the cover will fly out and cause an accident!
3. After turning the cover, be sure to use a finger to touch the rotating head and the cover without gaps. If there is any gap, you should unscrew and re-tighten until the gap is confirmed and the centrifuge can be started.
IV. In the process of centrifuging, the operator must not leave the centrifuge room. If an abnormal situation occurs, the operator cannot turn off the power (POWER) and press STOP.
V. Do not use shoddy centrifuge tubes. Do not use centrifuge tubes that are aging, deformed, cracked, or of unqualified quality.
6. The last worker who uses the centrifuge on holidays and in the evening must leave behind a routine safety check.
VII. In the process of using the instrument, it is necessary to promptly contact our Lu Xiangyi centrifuge manufacturer when the machine malfunctions or parts are damaged. Do not disassemble the instrument by yourself.
Out of cap centrifuge and ordinary centrifuge advantages difference
Uncap centrifuge is a conventional laboratory centrifuge, widely used in clinical medicine, biochemistry, immunology, blood stations, medicine and other scientific research education and production departments, off cap centrifuge is also known as vacuum capillaries special cap centrifuge.
