Recycling welding service. Utilizing welding technology to create composite mold materials suitable for the purpose.
95% of the aluminum die-casting molds brought to our company are for the repair of damaged areas, while the remaining 5% are for regeneration of those areas due to processing errors or design changes. Welding aimed at restoring shape primarily considers obtaining mechanical properties similar to the base material, and the selection of welding materials is made accordingly. This document includes the basic elements of mold welding, as well as examples of oil pans, plate seals, and welded structural molds. To achieve a stable mold lifespan, there is no alternative but to perform welding according to the fundamentals. Therefore, it is essential to incorporate welding repairs into the manufacturing plan from the outset, or at least into the "mold maintenance system," and to allocate sufficient time for execution. 【Features】 ■ 95% of aluminum die-casting molds are for the repair of damaged areas ■ 5% are for regeneration of those areas due to processing errors or design changes ■ The selection of welding materials is primarily based on obtaining mechanical properties similar to the base material ■ Utilizing welding technology to create composite mold materials suited to the purpose *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company is engaged not only in the repair of aluminum die-casting molds but also in the repair of hot forging molds, cast machine parts, and various machine parts, as well as wear-resistant overlay welding for preventive maintenance. Additionally, we applied for a prototype development project under the national fiscal year 2009 supplementary budget "Support Subsidy for Product Development of Small and Medium-sized Manufacturing Enterprises (Support Project for Prototype Development, Support Project for Product Verification)" and our project "Development of Overlay Repair Technology for Aluminum Die-Casting Molds Utilizing Laser" was recognized and adopted as a support project for prototype development. Currently, we are fully committed to the "Development of Overlay Repair Technology for Aluminum Die-Casting Molds Utilizing Laser."
