Stack HIP provides HIP services to aerospace, defence, and medical customers. The company reportedly possesses the largest high-pressure HIP vessels in North America, enabling the processing of the biggest and most complex castings and additively manufactured metal parts. Post-closing, SMG will continue to operate its classical heat treatment and aluminium special processing facilities in Portland, Oregon; Spokane, Washington; and Salt Lake City, Utah.

“We’re excited to welcome Stack HIP customers, employees, and suppliers into the Kittyhawk family,” said Brandon Creason, President of Kittyhawk. “Stack HIP will allow Kittyhawk to service mission critical parts up to [160 cm] in diameter, enabling us to process the full array of components for our customers. At Kittyhawk, we commit every day to providing the best service and quality to our customers, and we’re thrilled to now do that with the added capabilities and dedicated employees of Stack HIP. We look forward to the continued relationship with SMG to deliver unmatched special processing services to our valued customers.”

Doug Puerta, CEO of SMG commented, “We look forward to continued collaboration with Kittyhawk to deliver a differentiated level of service, quality, and value to our shared customers. This transaction will allow both companies to further drive capacity, quality, and capabilities in our respective services to best serve the PNW market.”

“This is an important step in growing the platform specialized in this highly-differentiated HIP capability. The Company continues to benefit from strong industry tailwinds, and we are excited to support our customers by investing in capacity,” said David Stinnett partner at Trive.
