About Alentra

Alentra develops and manufactures plastic components and assemblies for medical, pharmaceutical, diagnostic, life science and consumer applications. Its capabilities combine custom blow molding for hollow containers with injection molding, product development, tooling support and assembly. The organization brings together Currier Plastics, Springboard Manufacturing, MOS Plastics and Sage Product Development under the Alentra name. For hollow parts, Alentra offers extrusion, injection and injection stretch blow molding for bottles, vials and other containers. Its injection molding programs span prototype development and production, supported by automated handling, process monitoring and inspection. Engineering teams connect part design and manufacturability with tooling and production planning; tool builds can involve domestic or international partners alongside on-site machining and maintenance. The company lists manufacturing operations in Auburn, New York, Rancho Cordova and San Jose, California, and product-development operations in Foxborough, Massachusetts. Its official contact page routes new project inquiries to the relevant team.
