Bronze Lead Frame for the Automotive Industry
Royal Die & Stamping manufactured this C519 copper bronze left hand lead frame for use in a transmission module application. We provided the tooling design, manufacturing, and progressive die-stamping, using our 220-ton Minster press. We used our in-line vision system and ultra emissions and acoustical testing which features the most advanced equipment and software, to monitor and check that critical dimensions were met.
Each frame weighed about 0.35 lbs (.158 kg); measured 276 mm (10.86") long and met the tightest tolerances of 0.03", a true position of .05 mm (.0019")
We verified that the burr heights on the stamped parts did not exceed 0.1 mm (.039"), and ensured the finished part was completely free of oil and grease.
