What is EDM (Electronic Discharging Machining)
Electrical Discharge Machining (EDM) is a precision manufacturing process where electrical discharges shape hard materials. There are three main types: Wire EDM for detailed cuts, Sinker EDM for molds and cavities, and Hole Drilling EDM for making precise holes. Ideal for materials like hardened steel and tungsten carbide, EDM is crucial in the aerospace, automotive, and medical industries. Its key advantage lies in its ability to maintain material integrity, making it perfect for complex designs.
EDM stands out in precision engineering for its exceptional accuracy, versatility in materials, and capability to produce complex geometries, making it a vital tool in modern manufacturing sectors.
Electrical Discharge Machining is a common manufacturing process that uses electricity to create a desired shape or achieve the mirror finish requirements. The thermal energy is used to shape material, instead of direct contact machinings, such as CNC machining or grinding method.However, only conductive material can be working in electrical discharge machining because the electrical interaction with the base material is necessary. The conductive material includes copper, steel, tungsten carbide, and titanium. The E.D.M process is particularly used in hard material machinin

Case studies and examples explore the value of EDM process in practical applications,
Sinker EDM in Deep Drawing Die Application
Project Overview
Developed a complex die for stretch film manufacturing, featuring a tungsten carbide insert in a steel base.
Material and Design
Chose tungsten carbide for its hardness and durability, embedded in a steel matrix. The design required intricate internal shapes.
EDM Process
Employed Wire EDM for its ability to precisely shape the hard tungsten carbide without distortion. The process involved multiple passes to achieve the complex geometry.
Challenge and Solution
The main challenge was machining the intricate design within the hard material. Wire EDM provided a distortion-free solution, allowing for detailed and accurate shaping.
Sinker EDM in Plastic Mold Making for Mirror Finish
Project Overview
The high-precision plastic injection mold required a mirror-like surface, utilizing Sinker EDM technology.
Material and Design
The mold was crafted from specialized plastic mold steel, known for its ability to be finely polished while retaining strength.
EDM Process
Sinker EDM was the selected technique due to its precision in sculpting intricate shapes and achieving specific surface textures, crucial for the mold’s function and aesthetics.
Challenge and Solution
The primary challenge lay in attaining the mirror finish on a complex mold surface. Sinker EDM provided the detailed accuracy needed for the mold’s intricate contours. Post-EDM, a series of fine polishing steps were employed to elevate the surface to a high-gloss finish.
