SIGMA OEM’s name has become synonymous with quality. Our Quality Assurance Experts start by thoroughly auditing each factory before approving it as a SIGMA OEM manufacturer. They examine every facet of the operation from the procurement of raw materials to the maintenance of equipment through the manufacturing process. SIGMA OEM employees, including engineers, quality assurance experts and technicians, work onsite at all factories to provide continuous oversight, ongoing technical support and frequent inspections. Finally, SIGMA OEM conducts Incoming Quality Control tests, during which random samples of inventory are shipped from factories around the world to our company headquarters for inspection.
Every new part receives a First Article Inspection (FAI) Approval before shipping, and we offer 100% MTR (Material Test Report) traceability verification. We also provide CMM Inspections. SIGMA OEM has the capability to comply with PPAP (Production Part Approval Process), the stringent manufacturer/supplier approval process that certifies parts before, during and after production.
Because we have “boots on the ground” in all SIGMA OEM factories, our customers can rest assured that SIGMA OEM’s products are the most reliable on the market today.
