About Alliance Precision Plastics

Founded in 1947 in Rochester, New York, as a tooling and stamping die supplier, Alliance Precision Plastics has evolved into a contract manufacturer with a second facility in Spindale, North Carolina. The company operates over 242,500 square feet of manufacturing space across both locations. Alliance provides custom injection molding, mold design, mold building, and value-added contract assembly, supported by in-house design and engineering, tooling, and quality assurance. Its 83 injection molding machines serve programs ranging from prototype to high-volume production, and a certified Class 100,000 (ISO Class 8) clean room enables contamination-sensitive molding and assembly. The company serves global OEMs in energy and utility, medical and life science, specialty markets, and industrial manufacturing. Customers rely on Alliance for critical-path components and subassemblies that require tight process control and regulatory compliance. Alliance's stated mission is to deliver a quality product on time at a fair price. It differentiates itself by integrating all manufacturing steps—engineering, tooling, molding, assembly, and quality—under one roof, backed by formal quality plans, dedicated quality engineers, and certifications including ISO 9001:2015, ISO 13485:2016, UL Listing, and FDA registration.
