Our Quality Assurance

At MasterEDM(EDM Wire manufacturer) factory, we consider rigorous product testing a necessity, not an option. This commitment to quality assurance forms the foundation of our reputation as a leading provider of premium EDM wires. Each spool of wire we manufacture is subject to an extensive array of tests designed to confirm its reliability, durability, and superior performance.

The testing process begins with the raw materials, which are meticulously inspected to ensure they meet our stringent quality standards. Once these materials are processed into our Brass, Galvanized, and Gamma EDM wires, they undergo a series of rigorous tests.

Coating Uniformity Test

For our coated wires, we use a Coating Thickness Gauge to check the uniformity and thickness of the coating, further ensuring the wire’s performance and longevity.

Surface Roughness Test

Using a Surface Roughness Tester, we examine the minute irregularities in the wire surface. This ensures the wire’s surface quality, which can significantly impact the accuracy of EDM processes.

Tensile Strength Test

Using a Tensile Testing Machine, we ensure our wires can withstand the rigorous demands of EDM processes, confirming their structural integrity under tension.

Diameter Consistency Test

A Micrometer or Laser Micrometer measures the diameter of our wires along their entire length. This guarantees that our wires deliver consistent performance in your manufacturing processes.

Straightness Test

To ensure the straightness of our wires, we use an Optical Straightness Checker or Straightness Measuring Device. These tools allow us to guarantee the precision required for accurate and clean cuts.

Composition Test

We utilize advanced equipment like XRF Spectrometers and EDS systems to verify the elemental composition of our wires. This ensures they meet exact material specifications for optimal performance in various EDM processes.

Spooling Test

Proper spooling of our wires is crucial to avoid wire breakage and machine downtime. We ensure this through visual inspection and, in advanced setups, automated systems with cameras and image processing software to identify any spooling issues.

Powder Drop Test

To ensure the stability and integrity of our wire’s coating during EDM processes, we conduct a Powder Drop or Dusting Test. This test measures the amount of residue or dust produced during operation, which if excessive, could affect the EDM process’s effectiveness and cleanliness.

Conductivity Test

The electrical conductivity of our wires is verified using a Conductivity Meter or a Four-Point-Probe Meter, ensuring they meet the highest standards required for EDM processes.
