Hoffer Plastics

Hoffer Plastics is a private, family-owned U.S. precision injection molding company that manufactures custom plastic components, sub-assemblies, and proprietary Lok-branded closures. While it serves multiple end markets, it has a meaningful healthcare-facing business in medical and pharma, supporting non-surgical medical components used in diagnostics, drug delivery, in-home monitoring, respiratory care, dental equipment, glucose monitoring, wearables, and medical packaging. The company operates as a commercial-stage manufacturing partner rather than a therapeutic drug developer, offering design for manufacturability, tooling, scientific molding, validation support, automation, assembly, traceability, and packaging services. Hoffer Plastics is MedAccred-certified for medical device plastics and also highlights ISO-certified manufacturing operations. Its business model is best understood as a diversified contract manufacturing and engineered plastics platform with healthcare exposure rather than a biotech or pharma pipeline company.
