High-Precision Machining for Complex & Hard Materials

Electrical Discharge Machining (EDM) is an advanced manufacturing process used to cut, shape, and machine electrically conductive materials with extreme precision. Using controlled electrical sparks, EDM removes material without any physical contact — making it ideal for complex geometries, hardened metals, and ultra-fine tolerances.

What is EDM?

EDM is a thermal process in which sparks are generated between an electrode and the workpiece. These sparks create tiny craters that gradually shape the material into the desired form. It is widely used where traditional machining tools cannot reach or cannot achieve the required accuracy.

Our EDM Capabilities

  • Used for cutting detailed shapes with outstanding accuracy.
    Perfect for dies, molds, precision components, and complex profiles.
  • Creates deep cavities, intricate pockets, and precise mold features.
    Best choice for mold tooling, punches, and hardened parts.
  • For ultra-small features, micro-holes, and miniature components.
    Used in medical, electronics, aerospace, and precision tooling.

Why EDM Is Used

  • Can machine very hard materials like tool steel, carbide, titanium, Inconel, etc.

  • Ideal for complex shapes, fine cavities, sharp corners, and intricate contours.

  • No mechanical force → perfect for delicate or thin components.

  • Achieves micron-level accuracy and mirror-like finish.

How Our System Works

Clear, Efficient & Quality-Driven Workflow

  • We begin by understanding your specific needs — product drawings, tolerances, materials, and application requirements. This helps us design a solution that fits perfectly into your process.

  • Our design engineers create detailed 3D models using advanced CAD/CAM software. Every dimension, angle, and feature is carefully planned to ensure accuracy, durability, and manufacturability.

  • Before manufacturing starts, the design is tested through simulations to predict performance, stress points, and machining behavior. This reduces errors and ensures the design is production-ready.

  • Using CNC machining, EDM, and other advanced processes, we convert the design into high-precision components. Every part is produced with strict tolerance control and premium-quality materials.
  • Each component undergoes thorough inspection — dimensional checks, tolerance verification, hardness testing, and finish analysis — ensuring the final output meets the required standards.

  • For tooling and assemblies, we perform trial fits and operational tests to confirm flawless performance before dispatch.

  • We deliver the project on time with complete documentation and provide ongoing technical support for installation, integration, and maintenance.
