Plastic Injection Molding

What Plastic Injection Molding does

Plastic Injection Molding, Inc. (PIM) is a privately held, family-owned custom plastic injection molding service provider headquartered at 2695 Battelle Blvd., Richland, Washington. Founded circa 2009 by Ken Williams and his wife Sharon Williams — originating from a conversation between Ken and his grandfather John Rector, founder of Western Sintering — the company operates a single facility serving regional and international manufacturers across medical, firearms, outdoor equipment, optics, thermal imaging, espresso, wheelchair, ammunition, and government research verticals. Named customers include Cadwell Laboratories, Olympic Arms, Western Sintering, FLIR Systems, Leupold & Stevens, MSR, PNNL, TiLite, and others.

The company's technical capabilities center on a fleet of eight injection molding presses spanning 25 to 230 tons of clamp force and up to 20 ounces of shot size, comprising Van Dorn presses (80-230 ton), Cincinnati Milacron (33 ton), and Boy presses (25 ton). This production capacity is supported by an in-house full-service machine shop with Haas VF2 CNC vertical machining, Cincinnati Milacron ram EDM, lathes, Bridgeports, surface grinder, and micro welder, enabling on-the-fly mold construction, modification, and repair. Secondary operations include Printex pad printing, hot stamping, three Branson ultrasonic welders, and insert capabilities. Service offerings span part design consultation using 3D CAD modeling, rapid prototyping, tooling and mold design (with offshore tooling partnerships supplementing in-house capacity), production molding, secondary operations, assembly, and packaging.

PIM operates a quote-based B2B go-to-market with no publicly disclosed pricing. Customer acquisition occurs through website quote forms, direct phone contact (toll-free 800.624.6285), and reputation-driven referrals. The company has no active digital marketing, social media presence, or paid acquisition channels. Revenue is generated through custom one-time production orders and professional services for tooling/mold design and secondary operations. There are no disclosed funding rounds, M&A activity, or external institutional ownership; the business remains independently held by the Williams family.

Direct peers

• EVCO Plastics: Custom injection molding contract manufacturer serving medical, industrial, and consumer markets with in-house tooling and design services. Comparable to PIM in offering full-service molding with secondary operations, but at significantly greater scale.
• Rosti Group: Global custom injection molding contract manufacturer with in-house tooling, assembly, and value-added services for industrial, medical, and consumer customers. Overlaps with PIM's full-service model and target verticals at greater scale and geographic reach.
• Hubs (formerly Protolabs Network): Global custom manufacturing platform connecting buyers with vetted injection molding and CNC partners. Competes directly for PIM's small-to-mid batch injection molding customers with instant online quoting and a distributed supplier network.
• Xometry: On-demand manufacturing marketplace that includes custom injection molding alongside CNC, sheet metal, and 3D printing. Competes with PIM for the same mid-market manufacturer buyer using a digital quoting platform rather than relationship-driven sales.
• Stack Plastics: Custom injection molder focused on medical, biotech, and electronics applications with ISO 13485 certification and in-house tooling. Comparable niche in medical/electronics injection molding, with the certification bench PIM currently lacks.
• Molded Devices Inc. Custom injection and structural foam molder serving industrial and commercial markets with design, tooling, and secondary services. Comparable custom-job-shop profile with broader process capabilities than PIM.
• Protolabs: Digital-first custom injection molding service bureau offering rapid prototyping and on-demand production across a wide tonnage range. Closest direct competitor to PIM's core offering, differentiated by scale, instant quoting, and automation rather than by customer intimacy.
• Tessy Plastics: Custom injection molder serving medical, automotive, and consumer products with in-house tooling, assembly, and secondary operations. Comparable scope and customer verticals to PIM, with substantially larger capacity.
• Plastek Industries: Family-founded custom injection molder providing design, tooling, molding, and packaging services across personal care, food packaging, and consumer goods. Closely comparable full-service, family-led model with deeper packaging capabilities.

Broad incumbents

• AptarGroup: Large global manufacturer of dispensing systems, closures, and plastic packaging components across consumer, beauty, food, and healthcare markets. Adjacent in plastics manufacturing but operates at far greater scale and vertical focus than PIM's custom job-shop model.
