Mold Restoration 

Most plastic injection molds require surface restoration during the life of the mold.  Specialty welders are needed because  of the precise nature of restoration and  the value of the die/mold. The difficulty in restoring delicate molds is in limiting the heat to the part, so as not to change the properties of the mold in the process or in the need to turn it around quickly.

There are many things to take into consideration before any thermal process is applied,and maintaining the mechanical and physical properties of the mold material is essential. Minimum heatinduced deformation, minimal material build-up and expedient cycle time all factor into lowering the overall cost of refurbishment. PF ,Inc.
