As good as new Forming punching or die casting tools are exposed to great strain every day. Over time wear tolerances or damage are inevitable. Conventional repair methods are time-consuming and costly. Distortion softening and crack formation limit their applicability. And frequently the final results do not meet the high quality standards of the tool and mold making industry. Components which have been produced in a refurbished mold may even fail the strict quality tests performed by the end customer. As a frequent result the mold must be replaced. Laser deposit welding is the solution to all these constraints and problems. Welding can be done on-site requires only a minimum of pre- and post-processing and achieves material qualities which are equal to the original product when new. Applications for Laser Deposit Welding • Polymer injection molds (Hot-work die steel) • Aluminum pressure die casting (Hot-work die steel) • Punching and cutting tools (Cold-work steels) • Die forging (Hot-work die steel) • Blowing mold tool
