Mold Craft teamed up with Celanese, Sodick and LPKF at NPE2015 to mold a vented processor housing, a complex part that simulates a medical device cover, using laser direct structuring (LDS).

Mold Craft created the small, thin-walled part with different surface finishes, special cavity inserts and very tight tolerances. The vented processor housing was made from Celanese Vectra LCP material, which offers high flowability, dimensional stability and fast cycle times. It was molded on an LP20EH3 micro injection molding machine from Sodick (W163) using a two-stage plunger injection. LPKF (S16133) engineered the feature-rich design of complex circuitry on the part. Using LDS, the plastic is processed with a laser and then plated with electroless copper, nickel and immersion gold just in those areas excited by the laser, which is called metallization.
