Quality
H&H’s roots are set in quality people, processes, and products. We are an ISO 9001:2015-certified injection molding company, and we run every tool on scientific molding principles—decisions based on process data, not operator guesswork.

STEP 1: MOLD DESIGN
Quality starts in mold design. Our engineering team works with customers on design for manufacturability up front — verifying with mold flow analysis that the part is repeatable before steel is cut, not after.
STEP 2: MOLD CREATION
Our Mold Making team works closely with the Design team to take drawings and turn them into the highest quality molds made in the Pacific Northwest. Our team has over 120 years of machining experience with the understanding that our customer’s are trusting us with getting it right the first time.


STEP 3: TESTING & PRE-PRODUCTION QUALIFICATIONS
Once the mold is made, our Quality and Operations teams conduct first-article inspection and full pre-production qualification. This includes PPAP submissions where required, plus Cpk studies, PFMEA, and Process Flow documentation—the qualification work that separates a mold that runs from a mold that ships approved parts.
STEP 4: REGULAR PMs, CLEANING & INSPECTION
Once the mold has been qualified, the Operations team conducts regular PMs on all equipment and molds. After each production run, a dedicated team member does a full cleaning and inspection to ensure it remains in the best shape for future runs. The Mold Making team will periodically perform mold tune-ups, a further enhancement to our standard PM program.


STEP 5: QUALIFICATION & ON-GOING PART QUALITY INSPECTION
Finally, our dedicated Quality team is involved in all steps surrounding qualification and on-going part quality inspection. We have a wide array of tools at our disposal to support initial part qualification, to on-going quality checks to ensure all parts are within specification.
