| Tech Tip...(More) | Preventing Production Rate Losses from Clogged IBC Air Flow Paths |
|||
|---|---|---|---|---|
Clogged IBC pipes or ducting significantly reduce production rate and width control performance. As film producers use multi-layer structures to encapsulate reclaim resin, the need to clean die pipes and IBC exhaust ducting needs to be checked no less than every 6 months. For those running six days per week, the residue will accumulate even quicker. |

It took only six months to block 40% of the flow area in this exhaust duct. This was a HDPE resin. In some cases, increasing the IBC chilled air temperature will reduce this effect. |  Click on image for enlarged view |
Clogged IBC outlet pipes prevent the IBC from removing air from the bubble. Chronic problems with the bubble overblowing result. This problem will rob you of 10-20% in production rate. Click here for in-depth article on this subject. |
