The what & why of laser welding

Laser welding produces finer, more detailed welds through its precise laser delivery system. This method delivers very low heat input to the workpiece, minimizing the heat-affected zone, distortion, and sink in sensitive mold steels and alloys. The low-heat approach prevents cracking, enables repairs on thin sections, and allows welding near heat-sensitive features or assemblies without preheating.

Laser welding for high-volume parts production

Laser welding for high-volume parts production requires  speed, precision, and repeatability. The use of a tightly focused beam as opposed to an electrode creates a clean, contamination-free weld in tight, deep, or hard-to-reach areas while also eliminating the risk of impurities in the workpiece.

Laser welding is ideal for components with tight tolerances and complex geometries, and the consistency and accuracy of welds makes laser welding a fast, efficient, and cost-effective choice for high-volume parts production and tooling.

Laser welding for for plastic injection molds

Laser welding revolutionizes plastic injection mold repair and maintenance by enabling precise, low-heat repairs that extend tool life without compromising surface finish or dimensional accuracy. Ideal for repairing injection mold cavities, cores, and inserts, laser welding is a fast and efficient method for plastic injection molding repair — we can turn around injection mold repairs in a matter of hours as opposed to days, helping you maximize uptime and productivity.

With an emphasis on preserving mold finishes and extending the service life, laser welding for plastic injection molds offers the precision and consistency to reduce scrap rates and ensure your molds are in top shape for optimized performance.
