Precision metal parts, primarily injection blow molds for plastic industry, can be extremely expensive, and often are made with complex metal compositions. Sooner or later, stress results in damage and cracks. Repairs methods on the market today may alter the metal composition around the repair and reduce the quality of the product. A defect in the mold could put a hold on production, now there is a way around this.
Alliance LaserWelding offers a new technique which eliminates these challenges. The use of laser welding technology allows for use on percision parts. For example, injection molding parts can now be altered and repaired exact accuracy.
Our primary advantage over other methods of repair, is our high level of quality. With the Alliance LaserWelding method heat sensitive surfaces are treated in a relatively distortion free manner. With our laser welding you will no longer have discoloration or branding spots associated with conventional methods.
Most importantly the costs associated with laser welding as compared to the option of creating a new mold, are tremendous. Give our laser welding method a chance and we guarentee your satisfaction.
The damaged area is filled with several different phases of treatement. New material from the filler rods is applied in different passes until the desired surface height is finally achieved. The weld occurs by focusing the laser beam on the surface of the part, and reaching a temperature of 2732º F at the focal point. A metallurgical bond between the base materials and the layer material occur at this point creating a thin boundry layer.
The material added to has a very specific compostition which fulfills the characteristics of mechanical, tribological, chemical, and thermal stress. The transfer of heat to areas outside of the welding area is prevented by an extremely short application of energy.
