Sinker vs. Wire EDM
Precision Cavity & Blind Hole Machining
Our Sinker EDM (Spark Eroding) is utilized for creating complex cavities, sharp internal corners, and intricate surface textures in hardened tool steels that traditional milling cutters cannot reach. Suitable for tooling features, sharp internal corners, complex cavities, and precision component details that require controlled electrical discharge machining.
- ▹ Complex mold cavities
- ▹ Intricate surface textures
- ▹ Hardened tool steels processing
Ultra-Tight Tolerances & Complex Profiles
Using continuous thin wire, our Wire EDM process cuts through thick, hardened metals with microscopic precision (up to ±0.005mm). This technology allows us to produce flawless extrusion dies, punch matrices, and key components with perfectly smooth finishes and zero mechanical stress.
- ▹ Microscopic precision (±0.005mm)
- ▹ Zero mechanical stress deformation
- ▹ Flawless smooth finishes
Why Our In-House Tooling Matters To Your Bottom Line
Shorter Lead Time for Samples
Because we do mold fabrication and modification 100% in-house, we eliminate external sourcing delays. We speed up your time-to-market significantly.
Micrometer-Level Precision
Achieving tolerances as tight as ±0.005mm means flawless product fit, no flashing on plastic edges, and superb cosmetic appearance of the final appliance.
100% Intellectual Property Protection
Your proprietary designs and innovative mechanisms remain strictly within our factory walls during the tooling stage. Zero risk of leakages to third-party mold shops.
Fast Engineering Changes (ECN) & Maintenance
If your market requires a design tweak, our EDM engineers can modify the mold in days, not weeks. We also perform proactive mold maintenance to ensure zero production downtime.
