Hi-Rel Plastics & Molding is ISO 13485 certified and supports medical device, diagnostic, healthcare, laboratory, and pharmaceutical-product manufacturers.
Medical programs often involve more than an individual molded component. They may require multiple manufacturing and secondary processes such as molding, machining, adhesive bonding, ultrasonic welding, printing, assembly, inspection, and packaging.
Hi-Rel Plastics & Molding can combine medical manufacturing with:
By integrating these operations, customers can reduce the number of outside suppliers involved in producing a completed medical component or assembly.
Packaging requirements for medical applications are customer- and product-specific and should be evaluated according to cleanliness, handling, regulatory, transportation, and application requirements.
Hi-Rel Plastics & Molding is AS9100 certified and supports aerospace and defense manufacturers requiring precision plastic and metal components, controlled secondary operations, assembly, and packaging.
Aerospace components may have critical surfaces, dimensions, finishes, documentation requirements, or handling requirements that need to be considered during packaging.
Custom packaging can help protect aerospace and defense components during:
Packaging can be coordinated with molded or machined aerospace components, mechanical assemblies, cable assemblies, and other secondary operations.
Precision-manufactured components can be damaged by improper handling or packaging even when the parts leave the manufacturing process within specification.
Custom protective packaging can be designed to help reduce risks associated with:
Hi-Rel Plastics & Molding can evaluate the geometry, material, cosmetic requirements, fragility, weight, and shipment conditions of each product when developing a packaging approach.
Protective foam, dividers, individual bags, trays, cartons, or other customer-approved configurations can be used depending on project requirements.
Many customers require parts to be assembled before final packaging.
Our assembly services can be combined with custom packaging to provide finished subassemblies or completed products ready for shipment.
Assembly programs may include:
Combining assembly and packaging services under one roof can reduce handling and simplify the movement of products from individual components to packaged assemblies.
For qualifying products, Hi-Rel Plastics & Molding can integrate custom packaging with filling and sealing operations.
This can be particularly valuable for products using blow molded bottles, containers, dispensing components, closures, and other plastic packaging components.
Combining manufacturing, filling, sealing, labeling, and packaging can help customers reduce the number of separate production suppliers involved in their program.
Product packaging often requires labels for identification, traceability, branding, warnings, instructions, barcodes, or other customer-required information.
Hi-Rel Plastics & Molding can combine custom packaging with label application and related secondary operations.
Labeling can be incorporated into the manufacturing workflow before final packaging and shipment.
Products requiring logos, symbols, text, instructions, identification, or decorative graphics can also utilize our pad printing services.
Pad printing can be completed before product assembly and final packaging, helping customers consolidate multiple finishing operations with a single manufacturing partner.
Products requiring bonded components can utilize our adhesive bonding services before final inspection and packaging.
Adhesive bonding can be used for appropriate plastic-to-plastic, plastic-to-metal, and multi-material assemblies depending on substrate compatibility and customer specifications.
Once assembled and inspected, products can move directly into the required packaging operation.
For compatible thermoplastic components, ultrasonic welding can provide a permanent joining method before final packaging.
Hi-Rel Plastics & Molding can combine ultrasonic welding, assembly, inspection, and packaging as part of an integrated manufacturing program.
This can be particularly beneficial for medical, electronics, automotive, industrial, and consumer products containing multiple molded plastic components.
Our custom packaging services can also support components produced through plastic and metal CNC machining.
