Overview by DSI Solution | Offered in Malaysia by SYMTRACE

DSI Solution brings over 20 years of expertise in mold and die restoration using advanced pulsed laser welding technology — now available in Malaysia through our official partner, SYMTRACE.

Unlike conventional TIG welding, which often introduces excessive heat leading to deformation, stress, and inconsistent repair quality, pulsed laser welding offers a controlled, low-heat, and precision-based process that protects the integrity of your molds and dies. It’s ideal for fine feature work, deep-area repairs, and critical surfaces, delivering results that are not only durable but often stronger than the original.

We also address a common misconception: pulsed laser welding is not a temporary patchwork — it is a long-term, high-performance solution that restores tooling to its original performance standard, sometimes even exceeding it in terms of wear resistance and surface finishing.



What We Offer

Combining custom-designed laser wires with ultra-precise pulsed welding, we provide solutions for:
• Shape modifications
• Crack and flash repairs
• Ejector pin hole restoration
• Deep area (rib) welding
• Surface finishing (mirror & etching)
• Wear and scaling damage restoration
• Pin-hole (porosity) and fine detail repairs

Plastic Injection Mold Maintenance

We use DSI M90 and DSI M90 PK “Polish Kraft” wires for:
• Mirror surface and parting line (PL) repairs
• Deep rib welding
• Ejector pin hole repair
• Grain etching surface restoration

Benefits:
• Lower heat input = No distortion
• Polish-ready finish with high grain structure
• Fast high-speed machining post-repair
• Covers roughness grades from #200 to #30,000
• Up to 50% faster maintenance time with no reworks required





Die-Casting Mold Maintenance

Utilizing DSI M70/12, M55, and MAS1C for:
• Crack and wear repair
• Deep deposit welding
• Ejector hole maintenance
• Shape modifications

Advantages:
• No need for pre/post heat treatment
• Hardness increases from 35HRC to 53HRC after aging
• Materials up to 2,400 Mpa tensile strength
• Extend tool lifespan by up to 20% more production shots





Press Dies Maintenance

Welding under 50°C inter-pass temperature allows safe repair of:
• Heat-sensitive materials (SKD11, cast iron)
• Pinholes
• Cracks
• Dimensional distortion-sensitive areas

Key Strengths:
Room temperature welding, No cold/hot cracking, Custom wire solutions (DSI M90, M10), Excellent for cast iron with porous damage

 

What sets DSI’s solution apart is the combination of machine, people, and process:
• ' German-engineered pulsed laser machines for unmatched precision
• ' Certified welders trained in micro-repair and high-spec materials
• ' Certified DSI filler wires, custom-developed for exact applications

This synergy ensures a consistent, traceable, and production-grade repair that meets the rigorous standards of today’s molding and stamping industries.

Whether you’re in plastic injection, metal stamping, or die casting, our services support high-precision maintenance — extending tool life and performance with minimal downtime and maximum reliability.
