JB Plastics

What JB Plastics does

JB Plastics, Inc. is a US-domestic custom plastic injection molder headquartered at 1921 East Edinger Ave., Santa Ana, California, with 11–50 employees and operations dating to 2000. The company's core offering is custom injection molding on eight Toyo presses with clamping forces from 90 to 500 tons, supporting both high-volume runs of 10,000+ parts and short-run/low-volume production using aluminum or lower-grade steel molds. Tooling is designed in-house using 3D CAD systems with computerized simulation of filling, cooling, and shrinkage, supplemented by laser-sintered quick-turn tool inserts delivered in 7–10 days and modular insert systems for low- and medium-volume work.

The business is vertically integrated beyond molding: JB Plastics provides secondary operations (sprue and runner trimming, drilling, manual and automated assembly), custom tool making, Design for Manufacturability consulting, and a full fulfillment stack including warehousing with real-time inventory, pick-and-pack shipping via FedEx and UPS Worldship, and freight brokerage across truckload, LTL, flat bed, air freight, and international shipping with customs handling. The company serves a horizontal mix of end markets — consumer products (caps, closures, containers, displays), automotive/motorcycle components, electrical/mechanical parts, NSF-certified food/beverage items, non-intrusive medical packaging, and industrial/construction products — and explicitly positions itself as a domestic alternative to offshore manufacturing, emphasizing IP protection, shorter lead times, and tighter quality control.

JB Plastics generates revenue through project-based custom manufacturing contracts (quote-based pricing), with services bundled from part design through distribution. The company operates a sales-led GTM motion primarily through phone outreach (714-541-8500), website contact forms, and educational content marketing around reshoring. Since April 30, 2021, JB Plastics has been a wholly-owned subsidiary of Pelsis Group, a diversified conglomerate that also owns B&G Equipment and Curtis Dyna-Fog; David Smith continues as Chief Operating Officer and Azael Silva as Plant Manager, both reporting to Todd Pawlowski (General Manager for the Americas at Pelsis), while founders Bruce and Julie Donoho transitioned to strategic consultant roles for the integration.

Functional benefit

Products and services

• Custom Injection Molding High-volume plastic injection molding (typically 10,000+ parts) using precision tooling molds run on 8 Toyo presses with clamping forces from 90 to 500 tons, capable of handling mold footprints up to 28\" x 28\". Offered to OEMs and brand owners across consumer, automotive, electrical, and industrial verticals.
• Short-Run Plastic Injection Molding Low-volume injection molding service using aluminum or lower-grade steel molds for production runs typically under 10,000 units, sometimes as low as a few hundred or under 100 units. Targets startups, prototype programs, bridge-to-production, and niche product lines where high-volume tooling is uneconomical.
• Custom Tooling / Tool Making Custom tool design and fabrication services including prototype tooling, bridge-to-production tooling, and production tooling. Uses 3D CAD systems, modular inserts, laser sintering (7–10 day quick-turn inserts), precision EDM, and mold types such as hot runner, straight open/shut, triple plate, side action, and multi-cavity.
• Secondary Operations Post-molding manufacturing services including sprue and runner trimming, hole drilling, manual and automated assembly, and custom-designed automated assembly solutions. Provides parts ready for direct integration into customers' products or downstream packaging.
• Design for Manufacturability (DFM) Services Engineering consultation service providing Design for Manufacturability input in the early product design phase, including material selection guidance, mold design review, and production efficiency optimization to lower production times and costs.
• Fulfillment Services Comprehensive end-to-end fulfillment including final product assembly, warehousing with real-time inventory tracking, pick-and-pack shipping via FedEx and UPS Worldship, and domestic/international freight distribution with customs handling. Offered to customers needing complete manufacturing-to-distribution supply chain management.
