Port Erie Plastics

What Port Erie Plastics does

Port Erie Plastics is a family-owned custom plastics manufacturer founded in 1953 by Henry J. Witkowski and currently controlled by the Witkowski family, with William C. Witkowski as majority owner and CEO. Operating from a single 615,000-square-foot manufacturing complex on 69 acres in Harborcreek, Pennsylvania, the company specializes in high-volume custom plastic injection molding, low-pressure structural foam molding for thick-wall large-format parts (0.200"–0.500" wall thickness, up to 7.5 feet in length), and plastic extrusion. The technology platform comprises nearly 90 injection molding machines ranging from 55 to 1,650 tons, four low-pressure structural foam machines, eight extrusion lines, two blow molders, and a fully equipped in-house tool room with CNC milling, EDM, and CAD/CAM capabilities. Collaborative robots with IMMI communication are integrated for insert placement and part extraction.

The company's go-to-market is enterprise field sales targeting OEM customers across industrial/durable goods, consumer products, building and construction, material handling, lawn and garden, and medical products. Each program is assigned a dedicated project engineer providing technical ownership from quote through production, and the company offers turnkey vertical integration including mold design and build, molding, secondary operations (assembly, decorating, welding, machining), warehousing (275,000+ sq ft), JIT distribution, and retail/wholesale fulfillment. Notable certifications include ISO 9000, NSF, IAPMO, Intertek, UL, and USFCR Verified Vendor status, supporting compliance-driven programs in plumbing, construction, and medical. Customers retain ownership of transferred tooling (150+ molds in one disclosed program alone), creating switching costs and long-term program lock-in.

Revenue is generated through quote-based, project/program pricing on multi-year supply agreements with volume-based pricing negotiated per OEM program. The most recently disclosed revenue figure is approximately $60 million in annual sales from a 2016 news article; current revenue is not publicly disclosed. Beyond contract molding, the company sells Skidmarx, a proprietary branded plastic pallet line, as a finished good. Port Erie operates roughly 400 employees across three shifts in a 24/7 production environment and serves customers primarily in the Pennsylvania, Ohio, and New York region with a national customer base.
