Die-sinking EDM

SCHWEIZER TECHNOLOGIES: Specialist in die-sinking EDM

SCHWEIZER TECHNOLOGIES is a specialized manufacturer of customer-specific industrial components using die-sinking EDM. Die-sinking EDM, also known as spark neurososive lowering, sinking spark erosion or die-sinking erosion, is a method of spark erosion.

In many branches of industry, die-sinking EDM is suitable as a machining process that complements machining. SCHWEIZER TECHNOLOGIES uses die-sinking EDM to manufacture customer-specific components and tools that have high demands in terms of electrical conductivity - of course independent of hardness and strength.

Main areas of application in the field of die-sinking EDM

The non-contact manufacturing process is particularly suitable for the precision production of complex shapes made of materials that are difficult to machine. Especially in tool and mold making, die-sinking EDM and drill erosion is one of the most important manufacturing techniques. SCHWEIZER TECHNOLOGIES manufactures the die-sinking EDM process for the following typical areas of application and industries:

  • Die-sinking EDM for the medical industry
  • Die-sinking EDM for the Automotive Market
  • Die-sinking EDM for the electronics industry
  • Components for turbine construction
  • Injection moulds
  • Die casting moulds
  • Forging dies
  • Prototypes

Other erosion methods: wire EDM and drilling EDM

Of course, SCHWEIZER TECHNOLOGIES does not only manufacture in the die-sinking erosion process - wire EDM and drilling EDM are also available, for example for the production of:

  • Cutting and punching tools
  • Profile Tools
  • Extruder tools
  • Die-sinking EDM electrode

Advantages of die-sinking EDM

The die-sinking erosion process offers decisive advantages over other manufacturing processes such as classic machining:

  • highest precision
  • maximum flexibility
  • best surface qualities


Use of materials and machines

By means of die-sinking EDM, all electrically conductive materials such as metals, graphite, alloys, ceramics, etc. can be processed. Even demanding materials such as carbide, molybdenum, tantalum, graphite and tungsten can be processed by die-sinking erosion:

  • Steel
  • Alu
  • Copper
  • Titanium
  • Graphite
  • Ceramics
  • Carbide
  • Molybdenum
  • Tantalum
  • Tungsten

Without exception, SCHWEIZER TECHNOLOGIES relies on machines from quality leader Sodick for die-sinking EDM.
