What WJ does
W-J Incorporated is a privately held industrial manufacturer founded in 1972 and headquartered in Solon, Ohio. The company designs, manufactures, and repairs feedscrews, barrels, and related components for plastics and rubber processors using injection molding, blow molding, and extrusion equipment. Its product portfolio includes new replacement parts that meet or exceed OEM specifications as well as custom-engineered designs for specific performance improvements, complemented by components such as screw tips, non-return valves, nozzles, mixing sections, and heater bands.
The company's technical foundation rests on in-house precision CNC machining, specialized CAD/CAM design software, and Plasma Transfer Arc (PTA) hardface welding for repair and rebuilding. Manufacturing capabilities cover diameters from 14mm to 254mm and lengths up to 242 inches. All production is conducted at a single 42,000 sq ft facility in Solon, Ohio. The repair and rebuilding service line — enabled by PTA welding — allows W-J to restore worn or damaged feedscrews that other firms decline, positioning the company as a cost-effective aftermarket alternative to OEM purchases.
W-J operates a B2B enterprise field sales model targeting plastics and rubber manufacturers, with customer acquisition through toll-free phone lines, online contact forms, and PDF quote request submissions. Revenue is generated across three streams: new parts manufacturing, repair and rebuilding services, and consulting/field services (on-site inspection, troubleshooting, installation, and preventative maintenance). Pricing is entirely quote-based with multi-year contract cadences, and no public pricing tiers are disclosed. The company maintains industry affiliations with SPI and MAPP trade associations and runs Google Ads and Google Analytics remarketing campaigns alongside social media presence. Revenue, headcount growth, and ownership details are not publicly disclosed.
