From initial part evaluation and prototyping through tooling, production, machining, assembly, finishing, and packaging, Hi-Rel Plastics & Molding provides a broad range of aerospace contract manufacturing services from our California manufacturing operation.
Our aerospace manufacturing capabilities include plastic injection molding, blow molding, thermoforming and vacuum forming, rotational molding, mold and tool manufacturing, plastic and metal CNC machining, assembly, and a variety of value-added secondary operations.
Hi-Rel Plastics & Molding provides custom aerospace plastic injection molding for precision components requiring repeatability, complex geometries, dimensional stability, tight tolerances, and high-performance engineering materials.
Our custom plastic injection molding services support prototype, low-, medium-, and high-volume aerospace production programs.
Applications may include:
Our engineering and manufacturing teams can assist with material selection, Design for Manufacturability (DFM), prototyping, tooling development and production planning to help transition aerospace components efficiently from design to manufacturing.
High-accuracy molding processes ensure components meet exact aerospace specifications.
Experience with advanced resins designed for strength, thermal stability, and lightweight performance.
Manufacturing expertise for intricate, high-detail components with consistent results.
Strict process control ensures reliability and repeatability across every production run.
Material selection is critical for aerospace components where weight, temperature, chemical exposure, mechanical strength, flame performance, dimensional stability and electrical properties may influence component performance.
Hi-Rel Plastics & Molding works with a broad selection of engineering and high-performance thermoplastics, including materials such as:
Material selection depends on the specific mechanical, environmental, regulatory and performance requirements of each aerospace application.
Hi-Rel Plastics & Molding’s custom blow molding services provide another manufacturing option for lightweight hollow aerospace and ground-support components.
Depending on component geometry and performance requirements, blow molding can be used for products such as:
Our blow molding capabilities include extrusion blow molding (EBM), injection blow molding (IBM), and injection stretch blow molding (ISBM), giving customers access to multiple manufacturing technologies through a single supplier.
For larger lightweight components, panels, covers, trays and enclosures, Hi-Rel Plastics & Molding provides custom thermoforming and vacuum forming capabilities.
Potential aerospace applications include:
Thermoforming can provide an economical manufacturing solution for relatively large plastic components while maintaining low part weight and allowing considerable design flexibility.
Hi-Rel Plastics & Molding also offers custom rotational molding for large, durable hollow plastic products and components.
Potential aerospace and defense applications include:
The availability of injection molding, blow molding, thermoforming, vacuum forming and rotational molding allows Hi-Rel Plastics & Molding to help customers select a manufacturing process based on the component’s geometry, quantity, tooling requirements, material and performance objectives.
Successful aerospace production begins with reliable tooling.
Hi-Rel Plastics & Molding provides custom mold and tool manufacturing services supporting injection molding, blow molding, thermoforming, vacuum forming, rotational molding and other manufacturing processes.
Our tooling support can include:
This integrated approach allows customers to work with Hi-Rel Plastics & Molding from product development and tooling through production and assembly.
Aerospace programs frequently require more than molded plastic components.
Hi-Rel Plastics & Molding provides plastic and metal CNC machining and additional manufacturing services to support custom components and assemblies.
Combining molded plastic parts, machined plastic components and metal components can help customers consolidate suppliers and simplify purchasing, quality coordination and production management.
Our team can support individual components as well as multi-component manufacturing programs requiring several different processes.
Hi-Rel Plastics & Molding can take aerospace components beyond molding and machining through assembly services and secondary manufacturing operations.
Available services include processes such as:
By combining molding, machining and value-added operations, Hi-Rel Plastics & Molding can provide customers with more complete turnkey aerospace manufacturing solutions rather than supplying only an unfinished molded component.
Quality management is especially important when manufacturing components for aerospace and other demanding industries.
Hi-Rel Plastics & Molding Corp. operates under an AS9100 Rev D certified quality management system, supporting manufacturing processes designed around consistency, documentation, process control and continuous improvement.
