Our hunger for innovation leads to investments in our facility and people that allow us to tackle 1-2MM tooling programs successfully.

CNC: Best-in-class machines f-rom Yasda, Makino, Roders, and Mazak are used to provide accurate, repeatable results. Graphite machining cell includes 3R robotics for true 24/7 machining capacity.

EDM/WEDM: Five sinkers f-rom Mitsubishi sit adjacent to three Fanuc Wire EDMs. 3R Robotics in EDM cell are also used for true 24/7 manufacturing capability.

Polishing and Laser Welding: Extreme remains committed to a strong internal department who compliments our outside polishing specialists. Rofin Laser Welder allows us to repair or revise your molds quickly, accurately and within our complete control.

Finishing: Our toolmaking specialists use best-in-class grinding equipment f-rom Mitsui and Okamoto to complete the most critical operations on our molds. These machines are built to hold tenths, and there is no room for accuracy degradation on the last steps of mold manufacturing.

Mold Quality Control: Our OGP machine offers touch, laser and vision capability all within one machine. Detailed inspection reports are provided for critical areas of all injection molds we build. Brown and Sharp CMM is used to inspect every electrode we manufacture, before it is approved for use by our EDM dept.
