We would like to introduce examples of high-difficulty welding processing by Castem Co., Ltd. Narrow and deep areas such as "ribs and deep holes" that are difficult to weld using conventional welding (TIG). Minimal welding that does not interfere with adjacent surfaces due to repairs from component deformation. Achieving all kinds of high-difficulty welding. Before giving up on large-capacity laser welding for molds with significant buildup, such as die casting, or for extensive and long-distance welding areas, please consult us. 【Examples】 〈Body Valve Welding Processing〉 ■ Full circumference welding of E-pin hole inner diameter ■ Mold vertical wall shape section ■ Vertical wall shape and full surface buildup ■ Full circumference welding of slide lateral hole inner diameter ■ Full surface welding of cylindrical shapes due to design changes *For more details, please refer to our catalog or feel free to contact us.

• Processing Contract

It contributes to improving the wear resistance during repairs of aluminum die casting and low-pressure casting molds, leading to longer mold life. We propose repairs tailored to customer needs using welding rods made from materials such as maraging steel and SKD61, as well as cobalt-free materials. For areas with a high frequency of symptom recurrence, we use welding wires designed for wear resistance to suggest longer mold life.

• Resin mold

We are regenerating molding machine parts through precision welding with YAG lasers, and additionally performing ultra-hard coating treatment to enhance durability. In addition to regeneration, we also sell various new screw products. We propose the use of ultra-hard coating on general-purpose parts (at low prices). 【Features】 ■ Regeneration of molding machine parts that were previously discarded ■ Achieving 1.5 to 3 times the durability of new parts *For more details, please refer to the catalog or feel free to contact us.

"YAG laser precision overlay welding" enables fine welding that is difficult with conventional argon welding by using a laser that emits powerful infrared light. The post-welding polishability, durability, and hardness are almost equivalent to that of the base material. Welding can be performed without touching the nearby shapes. It realizes processing such as regeneration, modification, and repair that was previously impossible. 【Features】 - Minimal deformation, discoloration, oxidation, and shrinkage due to heat - Minimal deformation and shrinkage relative to the base material - Ultra-precise welding is possible, significantly reducing post-processing time - Welding is possible in areas where the torch cannot reach, such as with TIG welding - Welding of non-ferrous metals is also possible *For more details, please refer to the catalog or feel free to contact us.
