The common failures and solutions about epe foam machine

Sheet is cracked reasons:

1. Die is tighten more for thin sheet

2. There is impurities in mould

3. Filter net is movement or leaked


Solution:

1. Loosing the die a little

2. Loosing the mould to let impurities outside, then tighten immediate.

3. Exchanging the filter net



Bubble on surface of sheet, and with holes till cracks many place reasons:

The temperature is lower in water cooling zone


Solution:

Bubble or many holes, reduce the water flow; cracks many place, restart the machine.


Sheet thickness is uneven reasons:

1.inside and outside die is not justify

2. Deformation of mould

3. Monostearin is too many


Solution:

1.adjusting jackscrew to let it justify

2. Repair the mould

3. Reduce monostearin


Bubble is too large reasons:

1.talcum powder is too less 

2.butane is too less


Solution:

1.adding talcum powder 

2.adding butane


sheet spotted reasons:

1. Monostearin is too much 

2.the temperature is too low of 7th and 8th zone


Solution:

1. Reduce monostearin 

2.higher the set temperature or turning small the water flow



Longitudinal stripes deep reasons:

Butane is too much, 

Talcum powder is too much


Solution:

Reduce the butane 

Deduce the talcum powder



Rough surface, with white abb  reasons:


1. Die gap is too large

2.the extruding qty is not enough


Solution:

1.tighten the die

2.improve the machine engine speed and adding butane and monostearin



Sheet is crisp, easy to  break  reasons:

1.monostearin is too much 

2. Machine head temperature is too low


Solution:

1.reduce monostearin 

2.increase the machine head temperature


Sheet is shrink reasons:

1.monostearin is too less

2.machine head temperature is too high

3.the temperature is lower than 5℃ in plant

Solution:

1.increase monostearin

2.reduce the machine head temperature

3.raise the plant temperature


Sheet strip is too light  reasons:

1.machine head temperature is too high

2.butane is too less


Solution:

1.reduce the machine head temperature

2.adding butane


Sheet is off tracking reasons:


1.the gap of die is nonuniform

2.auxiliary malposition


Solution:

1.adjusting the die gap

2.adjusting the auxiliary position



Sheet is break for often reasons:

Traction speed is too fast


Solution:

Slowly the traction speed



Sheet is cracking at the confirmed position reasons:

Bruise on die


Solution:

Repair the die
