EDM Power Feed Contacts

Power feed contact can also be referred to as a 'conductive block'. 

It is the main consumable part used in a wire EDM machine, responsible for feeding power, as the name suggests.​

Materials:

The material is mainly tungsten carbide, although some feed contacts also have pure tungsten or copper tungsten available. 

The material is the most important factor in determining quality. 

Tungsten carbide with different quality grades, high tungsten content, provides better hardness and a longer lifetime. 

Special treatments such as Ti-coating and black coating can improve the lifetime of feed contacts. 

Pure tungsten and copper tungsten have higher hardness and longer lifetimes, but they are also much more expensive.​

Machining method​:

Additionally, the machining method and machines determine the quality of the power feed contacts. 

We use professional imported grinding equipment for mirror machining instead of manual polishing. 

The surface flatness ensures stable conductivity and proportional wire. 

The machining method is particularly crucial for M009, H002, and H003 due to the angled faces they have.

My boss started his business with a workshop that manufactured power feed contacts for a Taiwan-based EDM parts trading company. 

With over 15 years of experience, our techniques have been updated and the quality is now quite stable.
