About SIGMA OEM

SIGMA OEM has a long history and deep expertise in all facets of the castings business.  For over 35 years, we have been sourcing and procuring product from overseas for use throughout North America. SIGMA OEM can manufacture pump casings, valve bodies, brake calipers, impellers, counterweights, H Frames, gears, and precision castings—to name but a few—and we can produce virtually any casting item required by our customers. We utilize large-scale manufacturing facilities in emerging markets, and we have qualified SIGMA OEM personnel on the ground at each factory.  Our established infrastructure means that customers benefit from excellent supplier relations, reliable logistics, and onsite responsiveness.  The scale of our operation enables us to service small, medium, and large orders efficiently and cost-effectively.  Our supplier relationships are based on trust and respect earned over three productive decades.  Customers benefit from our long history in OEM; we know the people, the policies, and the protocols.  SIGMA OEM offers solutions that enable our customers to reduce the total cost of ownership (TCO).

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 stations engineers at all factories to provide continuous technical support and frequent quality assurance 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.
