Problems and Solutions | ||||
The Analysis For Shaping | ||||
Phenomenon | Analysis | Measure | ||
1.Bad binding | No enough time for heating | Prolong heating time or increase steam pressure | ||
Too high steam pressure | Prolong heating time or increase steam pressure | |||
Too long mature time | Reduce mature time for 6 to 24 hours | |||
Frothing beads'water content is to high | Blow cool-air or hot-air to dry,prolong mature-time but no morethan 24 hours | |||
Moist steam;high water content | Remove water from the steam | |||
Low expand rate | Control the expand rate from being too high | |||
Bad mould | Check whether the steam hole of mould is blocked up;whether accumlated filth in steam room does harm to heat-tramsfer;whether the mould is not tight,the steam is escaping | |||
2.Bad moulding unloading | Too long heating time | Reduce heating time | ||
Too high temperature | Reduce steam pressure | |||
Not enough cooling | Increase cooling water time,or prolong cooling time | |||
Rough mould surface | Coat mould-unloading agent or smooth the surface | |||
3. Surface shrinking of the products | Too long heating time | Reduce heating time | ||
Too high steam pressure | Reduce steam pressure | |||
Too fast cooling | Increase the temperature of cooling water;reduce cooling water;prolong cooling time | |||
Not enough mature-time | Prolong mature time for 6 to 24 hours | |||
Not enough feeding or uneven feeding | Check whether the feeding inlet is blocked up;increase the pressure of the compresses air;prolong feeding time;increase mould' space or use smaller pre-expand beads instead | |||
Too high expand rate | Adjust expand rate | |||
4. Bad binding of the appearance of products | Uneven feeding | Check whether the feeding inlet is blocked up,prolong feeding time; increase wind pressure ;increase mould's space | ||
Too much accumulated water in the mould | Prolong discharging time;increase blowing and discharging steam or air | |||
Uneven cooling and heating of the mould | Check whethe the steam hole is blocked up;whether the desigh of the mould is reasonable | |||
5. Expanding of the shaped products | Not enough time for frothing beads to be mature | Prolong mature time | ||
Not enough cooling | Prolong cooling time;increase cooling water;check the condition of the compontent | |||
6. Good binding on the surface,but bad inside | Too high steam pressure;too fast heating speed | Reduce steam pressure;prolong heating time | ||
Not enough mature time | Prolong mature time | |||
Moist pre-expand beads | Dry the beads | |||
Expand rate is too low;old raw material | increase expand rate;use new raw material | |||
Too much liniment | Inform the production plant to reduce the Liniment |
