Blown film extrusion

8/17/2010 3:34:18 AM

The manufacture of plastic film for products such as shopping bags is achieved using a blown film line. This process is the same as a regular extrusion process up until the die. The die is an upright cylinder with a circular opening similar to a pipe die. The diameter can be a few centimetres to more than three metres across. The molten plastic is pulled upwards from the die by a pair of nip rolls high above the die (4 metres to 20 metres or more depending on the amount of cooling required). Changing the speed of these nip rollers will change the gauge (wall thickness) of the film. Around the die sits an air-ring. The air-ring cools the film as it travels upwards. In the centre of the die is an air outlet from which compressed air can be forced into the centre of the extruded circular profile, creating a bubble.This expands the extruded circular cross section by some ratio (a multiple of the die diameter). This ratio, called the “blow-up ratio” can be just a few percent to more than 200 percent of the original diameter. The nip rolls flatten the bubble into a double layer of film whose width (called the “layflat”) is equal to ½ the circumference of the bubble. This film can then be spooled or printed on, cut into shapes, and heat sealed into bags or other items. An advantage ofblown film extrusion over traditional film extrusion is that in the latter there are edges where there can be quality (thickness,... ) variations.

what is the Mono Layer Blown Film Machine

8/4/2010 4:45:48 AM

Mono Layer Blown Film Machine is the most widely used plastic extrusion method is the packaging industry for manufacturing single layer film structure. A large number of machines are also available for multi-layer film structures. Monolayer blown film plants can be used to manufacture polymer films using a diverse range of polymers like PP, LD, LLD, HM, LLDPE, LDPE, HDPE, EVA, EVOH and PA (Nylon), etc. Mono Layer Blown Film Machine are manufactured using high quality raw materials that ensure durability and consistent performance. Wide range of monolayer blown film plants are available in various capacities that can be used for a variety of extusions. Continuous effort is being made to develop advance range of monolayer blown film that are cost effective. Some of the types of Blown Film Machine that are currently available in the market are: Mono Layer Blown Film Machine 2 Layer Coextrusion Blown Film Machine 3 Layer Coextrusion Blown Film Machine 5 Layer Coextrusion Blown Film Machine 7 Layer Coextrusion Blown Film Machine

Film blowing machine inverter often jump out and why?

7/15/2010 3:08:12 AM

You can control the keyboard display symbols motor control inverter manual to find problem solutions. My guess is the motor overload, inverter for their own protection automatically jump out. Solution: you can re-set the frequency parameter, or to the good state of repair motor! mainly poor low frequency electrical heat, fever, general motor itself when the cooling fan is not enough frequency. Power overload caused by insufficient heating temperature jump or burn motor inverter. Inverter parameter adjustment will jump properly. First, the choice of motor sports should first be required when the load average power, maximum power, converted to motor shaft side (may have gear, pulley and other deceleration device) to select the motor power, motor overload should also be considered. Motor manufacturers can provide the motor torque characteristic curve of motor characteristics at different temperatures will change. By the way: the order of selection is of course first and then select motor inverter based motor selection, because the control is not the ultimate goal is not inverter motor, but the mechanical load. Second, the frequency converter should be emphasized that the first selection should be based on current selection. For the average load, you can select the motor rated current inverter, which inverter rated current (that of conventional environment with maximum sustained operating current) is larger than motor rated current can be. However, the situation must be considered the emergence of the limit. Therefore also need to provide short inverter overload currents. The result: the inverter rated power may be greater than the motor power can also be less than the motor power, in fact, selection of the inverter is determined according to mechanical load, the conclusion: the final selection based inverter is the inverter current curves include mechanical load current curve.
