Blown Film and Pipe Die Cleaning

An important aspect of efficient blown film line operation is regular servicing of dies.  Effective die reconditioning maintains high levels of line performance by reducing system backpressure, film lines and maintaining uniform film thickness.  Some of the below are before and after pictures of a 3 layer film die.

Blown Film and Pipe Die Repair

After a number of years of service, blown film and pipe dies need more than regular cleaning and service to continue to operate.  Dies whose condition is beyond normal servicing often need to be repaired or rebuilt to continue to operate.  Most often, rebuilding a die involves stripping, polishing and replating of the entire die.  Depending on the condition of the die, remachining of seal and lip surfaces may be required to bring the die back to good operating condition.

Corrugated Pipe Mold Repair

The production of corrugated plastic pipe typically uses aluminum vacuum molds to form the outer ribbing on the pipe.  During normal usage, these aluminum vacuum molds require repair for wear and damage.
