Wire EDM uses an electrically charged wire to cut conductive material along a programmed profile. It is useful for through-slots, precision tooling profiles and hardened parts where mechanical cutting forces are undesirable.
Typical parts and project fit
This process is considered for tool inserts, through-slots and intricate conductive profiles. Tecpreva reviews the drawing, material condition, quantity and functional requirements before confirming the production route.
Drawing and inspection checklist
Identify conductivity, wire entry, part thickness, corner radius and recast-layer requirements. Supply a revision-controlled 2D drawing, STEP model, finish specification and critical dimensions. Machine positioning accuracy alone does not define achievable part tolerance.
Can wire EDM machine plastics or blind cavities?
Standard wire EDM requires an electrically conductive workpiece and a wire path through the cut. Most plastics are unsuitable, and blind cavities generally require milling or sinker EDM instead.
From first article to repeat production
Agree the fixture and datum strategy, first-article checks, sampling plan and dimensional report scope before production. Record revisions and protect functional surfaces during finishing and packing.
