Throwback Thursday: Moldmaking Using Wire EDM

Some of the conversations I have been having about EDM lately as well as the coverage we've been giving its latest advances moved me to look through our archives for some related content. I found an old article from the year 2000 that reflects on the applications in which EDM found its way back then. It was an interesting read.

Some of the conversations I have been having about EDM lately as well as the coverage we've been giving its latest advances moved me to look through our archives for some related content. I found an old article from the year 2000 that reflects on the applications in which EDM found its way back then. It was an interesting read.
 
The article examines the reasons for this "new" interest in a supposedly unrelated machining method and its impact on moldmaking, both physically and fiscally.  It shares 10 advantages of having a wire EDM in your mold shop:
 

1   Electrode making

2   Mold base work

3   Cavity work

4   Core pins and inserts

5   Core pin, ejector pin and ejector sleeve holes

6   "Designed in" or emergency venting

7   Related components

8   Shutoffs and stepped or contoured parting lines

9   Reduce/eliminate polishing

10  Significantly reduce direct labor costs

 

I believe we've come a long way!
