Complex Aluminum Casting Machining

Our die cast customer came to us needing support to machine their tighter tolerance, more complex work. They had previously machined these parts in-house but were challenged to keep a workforce skilled enough to run these more complex parts. WMPI moved the existing fixtures into our tool room and inspected them. We found that some repairs and modifications were needed to once again make parts to print. We were then able to conduct a Level 3 PPAP and get world-class quality parts into production.

WMPI has continued to run these parts for several years without any major quality issues. We have consistently achieved 98% on-time delivery for this customer with no non-conforming part returns. These parts involve milling, drilling, port tools, tapping and part washing. Parts are also inspected and separated for porosity issues.
