Plastic blow molding machine film about non-uniform solution!

Dalian blown film crewMembrane fold, the foundation reason is film transverse thickness uneven, even a very small, by gathering can also contrast significant fold, after effects become thin experimental film, film tear test, conflict coefficient and other measurement data.Dalian blown film machineGroup of manufacturers teach you solution!

Solution:

1, the cutting cooling air volume or mediate cooling air uneven situation.

2, to reduce the melt temperature, can be useful to reduce the melt liquidity, in contrast, when die extrusion is not due to the cooling air film bubble is inclined to form a thin film cooling.

3, herringbone plate Angle is too large, makes the film get squashed in a short moment, therefore present fold questions, should appropriate reduce the herringbone board Angle.

4, membrane mouth crowded is uneven, should be mediation model, make it in a vertical position.

5, low speed starting the first extrusion machine, investigation and starting current is normal, normal, and then gradually add the speed of the extruder.

6, opened the cooling fan and squeeze the air and on the traction roll and corona treatment machine.

So using plasticBlown film machineUse note:

1, check and add good reducer, the lubrication oil in the compressor, check the lubrication of mechanical transmission parts.Avoid dry operation damage the machine and noises.

2, operation of the machine operator can not stand in the front, lest appear accidental injury and operating personnel.When blown film machine feed fight with metal impurities in raw material and operating small tools such as damage to the hard object fall into the barrel of the machine.No gloves when operating rotating machine, in case involved in injury.

3, film forming conditions, and improve the forming temperature, cooling air temperature and blowing ratio;Increasing the film turbidity and glossiness;Vice to improve.

4, die discharging uniform, can wear gloves slowly lift pipe, pipe end will be closed at the same time, the micro into gas regulator, from central hole of the plug in a small amount of compressed air, and then carefully stiff foam frame, plates, and wear into the traction roller, guide roller and coiling

5, of the pipe blowing compressed air pressure to appropriate, cannot make the pipe burst, and to guarantee the stability of membrane tube symmetry, relative to guarantee the quality of production.

6, you must check each operation starting power supply wiring whether there is a disconnect, leakage;Check instrument damage is not normal.To ensure the safety of the parts first before starting the normal, lest affect production and cause an accident.

Plastics blown film lineManufacturers, production of plastic blown film machine, single layer film blowing machine,Three-tier co-extrusion blown film machineSuch as blowing film machine.We can produce various specifications according to user needs design and turn the head, rotating wind ring, such as to rapidly replace the device.Guarantees products, is responsible for the safe commissioning, training operators, welcome customers to negotiate, the choose and buy.
