What Custom-Pak does

Custom-Pak, Inc. is a privately held, vertically integrated industrial blow molding manufacturer founded in 1974 and headquartered in Clinton, Iowa, with 501-1,000 employees operating six manufacturing plants across the United States (Clinton, Dewitt, and Walnut Ridge) and Mexicali, Mexico. The company designs and builds its own energy-efficient blow molding machines, blow molds (including proprietary aluminum alloys), and integrated robotic automation systems, then uses that infrastructure to produce custom blow molded parts across three core product categories: Carrying Cases & Packaging, Consumer Products, and Industrial Parts & Components — serving OEM customers in hardware, appliance, lawn & garden, seating, electronics, housewares, toys, construction, medical, telecommunications, and automotive industries. The technology stack centers on extrusion blow molding with over 200 production lines, machine sizes ranging from 1 to 30 lb shots using 1, 2, or 4 heads per machine, complemented by 3D CAD design services, in-mold secondary operations (labeling, welding, inserting, punching, slicing, finishing), and automated vision- and laser-based quality inspection. Notable technical components include patented Quad, Tri, and Double Wall case designs, numerous in-mold technology patents, and a QC-10 aluminum mold alloy that increases hardness during use.

Revenue is generated primarily through contract manufacturing of custom blow molded parts under quote-based, multi-year purchase agreements with enterprise OEMs, with credit terms of 50% down on mold tooling (paid upon sampling) and net 30 days for part production FOB plant. Ancillary revenue and cost-side value come from three in-house mold building centers, a machinery development center that produces equipment for both internal use and potentially external sale, Midwest-Poly (a wholly owned recycling operation processing 20M+ lbs of waste plastic annually into reusable resin), warehousing and just-in-time distribution services, and competitive subcontracting for injection molding, rotational molding, metal components, painting, and assemblies. Go-to-market is direct enterprise sales supported by free confidential design assistance, content marketing via the company website, and three product development centers that reportedly develop one new blow molded product every business day for a customer. The company holds ISO 9001:2015 across all facilities, ISO 14001:2015 and ISO 45001:2018 in Mexico, FDA medical device registration, and was among the first worldwide to obtain both EPA and CARB certifications for blow molded fuel tanks.
