Electrical Discharge Machining at Rototip

Order from Rototip and get the best quality!

When precision is paramount in machining, turn to Rototip's EDM services. Whether you require basic wire EDM for straightforward parts with cost-efficiency and quick turnaround or seek advanced sinker EDM capabilities for intricate components demanding the highest precision, we're here to assist.

From rapid prototyping to high-volume production, every part produced through Rototip's EDM process comes with meticulous quality assurance documentation, guaranteeing that your specifications are met

Wire EDM

When precision machining is required on certain intricate geometries Rototip suggest its customers to employ wire EDM where a thin, electrically charged wire cuts intricate shapes with high accuracy.

Sinker EDM

When creating precise cavities or moulds in hard materials demands high precision, Rototip recommends Sinker EDM. In this process, an electrode and a dielectric fluid are used to achieve exceptional accuracy.

Hole Drilling EDM

For achieving small, deep holes with outstanding precision in challenging-to-machine materials, Rototip suggests Hole Drilling EDM. This method is ideal for intricate hole geometries.

Why Rototip

Process never been easier!

Best factories and workshops deliver quality but can hardly respond to customer demands on agility, price, close collaboration. Online manufacturing platforms are agile but overlook the requirements on quality, consistency and reliability. Enter Rototip. We focus on ensuring supply of top quality parts delivered consistently, sustainably, and reliably.
