(The tool shown here was fabricated for the injection molding of a 36 pin circuit board protector.)
This tool was designed to the customers supplied prints, and featured interchangeable components that would allow for the injection molding of four individual parts. The complexity and precision required for this mold utilized a number of our CNC machining and hard milling capabilities.
Fabrication entailed graphite milling, which was completed on our OKK machining centers, as well as wire and conventional EDM machining, done on a Mitsubishi wire EDM and a Charmilles Roboform sinker EDM.
The molded component would be molded from a 20% GF PBT Ultradur B 4300 G4 natural resin, with a green colorant.
It featured dimensions of 82.2mm in length (+.0/-.2"), 27.4mm in width, and 24.5mm in height (±.2mm), with a finish of RA 2.24 or smaller.
To verify the integrity and quality of the tool, initial part sampling and debugging was performed in-house prior to shipping to the customer in Myrtle Beach, South Carolina. The entire project, from design to delivery, was completed in just 10 weeks.
