Our capabilities can support components for:
Competitors in this market specifically optimize their pages around food-grade components, containers, closures, processing equipment, dispensing components, packaging and food-contact materials, making these important topical areas for this page as well.
Engineered to withstand extreme environments, mechanical stress, and demanding operational conditions.
Experience with advanced resins designed for strength, impact resistance, and long-term reliability.
Tight-tolerance molding ensures accuracy and consistency for mission-critical parts.
Quality-focused manufacturing delivers repeatable performance across every production run.
Hi-Rel Plastics & Molding provides custom plastic injection molding services for precision food and beverage components ranging from prototypes and lower-volume specialty components to ongoing production requirements.
Injection molding can be an effective manufacturing process for repeatable production of complex food and beverage components requiring dimensional consistency, detailed geometries, functional features and efficient production.
Potential applications include beverage dispenser components, equipment housings, knobs, handles, fittings, caps, closures, valve components, conveyor components, processing equipment parts, filtration components, connectors, brackets and other custom molded products.
Hi-Rel Plastics & Molding can also assist customers with material selection, DFM (Design for Manufacturability), Mold Flow Analysis, prototyping, tooling development and production optimization before a product moves into full production.
For hollow plastic products, Hi-Rel Plastics & Molding provides plastic blow molding services supporting custom bottles, containers, reservoirs and other hollow components.
Blow molding can be used for food and beverage applications including:
Hi-Rel Plastics & Molding can support extrusion blow molding (EBM), injection blow molding (IBM), and injection stretch blow molding (ISBM) requirements as appropriate for the product and project.
The ability to combine blow molding with mold manufacturing, prototyping, secondary operations and assembly gives food and beverage companies access to a broader turnkey manufacturing solution.
Hi-Rel Plastics & Molding also offers liquid silicone rubber (LSR) injection molding for flexible components used in food and beverage equipment and dispensing applications.
Potential LSR applications include seals, gaskets, diaphragms, flexible valves, dispensing components and temperature-resistant silicone components.
LSR can provide properties valuable to appropriate food and beverage applications, including flexibility, temperature resistance and long-term performance. Material selection and suitability should be determined according to the customer’s specific food-contact, operating and regulatory requirements.
Hi-Rel Plastics & Molding provides thermoforming and vacuum forming services for larger, lightweight and packaging-related plastic products.
Potential food and beverage applications include custom trays, packaging components, protective inserts, equipment covers, machine guards, liners and other formed plastic components.
Thermoforming can be particularly useful when a project requires large surface areas, relatively thin walls or an alternative to injection molding for appropriate geometries and production quantities.
For larger hollow plastic products, Hi-Rel Plastics & Molding offers rotational molding services.
Potential applications include bulk ingredient bins, storage containers, material-handling products, insulated containers, carts, reservoirs, tanks and other large durable components used throughout food production and beverage manufacturing facilities.
Having injection molding, blow molding, thermoforming, vacuum forming and rotational molding capabilities allows customers to evaluate the most appropriate manufacturing process for their component rather than being restricted to a single molding technology.
Successful production begins with properly engineered tooling. Hi-Rel Plastics & Molding provides mold and tool manufacturing services supporting injection molding and other manufacturing processes.
Our tooling capabilities can support:
Integrating engineering, tooling and production can help customers simplify supplier management and resolve manufacturability issues earlier in the product-development process.
Hi-Rel Plastics & Molding can support food and beverage projects beginning before production tooling is manufactured.
Through engineering support and 3D printing and rapid prototyping, customers can evaluate component geometry, fit, functionality and manufacturability before committing to production tooling.
DFM and Mold Flow Analysis can also help identify opportunities involving wall thickness, draft, gate location, material flow, cooling, potential warpage and other molding considerations.
This concept-to-production approach helps OEMs consolidate product development, tooling, molding and finishing with a manufacturing partner capable of supporting multiple stages of a project.
Hi-Rel Plastics & Molding Corp. maintains:
ISO 9001:2015 Certification
AS9100 Rev D Certification
ISO 13485:2016 Certification
These quality management systems support a disciplined manufacturing environment focused on process control, documentation, consistency and continuous improvement.
For projects requiring controlled manufacturing environments, Hi-Rel Plastics & Molding also offers cleanroom molding capabilities including:
Class 10,000 / ISO Class 7 cleanroom environments
Class 100,000 / ISO Class 8 cleanroom environments
Cleanroom capability can be valuable for appropriate food, beverage, packaging and dispensing applications where contamination control and manufacturing cleanliness are important.
This is worth emphasizing prominently. Competitors such as Rodon and D&M Plastics explicitly promote cleanroom manufacturing for food and beverage applications, demonstrating that this capability has both customer and search relevance.
Material selection is critical when designing plastic components for food processing, dispensing, storage, packaging and beverage applications.
Depending upon the specific product and customer requirements, commonly considered thermoplastic families can include polypropylene (PP), polyethylene (HDPE and LDPE), PET and other engineered thermoplastics.
Factors considered during material selection can include:
Where a component will have direct food contact, the customer-specified resin grade and applicable regulatory requirements should be verified for the intended application.
That wording is preferable to broadly claiming every material or component manufactured by the company is “FDA approved.” Competitor pages frequently target terms such as food grade plastics, FDA compliant food packaging, food-safe materials, and food-contact components.
Manufacturing frequently continues after molding. Hi-Rel Plastics & Molding provides a range of secondary services that can reduce the number of suppliers involved in a food or beverage manufacturing program.
Capabilities include assembly services, mechanical and cable assembly, ultrasonic welding, pad printing, label application, heat insertion and heat staking, adhesive bonding, surface finishing, plastic and metal CNC machining, custom packaging and other value added operations.
Combining molding, finishing and assembly can provide customers with a more complete contract manufacturing solution rather than purchasing individual components from multiple suppliers.
Food and beverage equipment can require a combination of molded plastics, machined components, hardware, cables and subassemblies.
In addition to custom plastic molding, Hi-Rel Plastics & Molding supports custom plastic and metal component manufacturing, mechanical assembly and cable assembly, allowing customers to consolidate multiple requirements within a single manufacturing program.
This capability can be particularly valuable to manufacturers of food processing equipment, beverage dispensing systems, automated packaging equipment and commercial appliances.
Food and beverage manufacturers need suppliers capable of producing consistent components while supporting engineering changes, tooling, production and downstream operations.
Hi-Rel Plastics & Molding offers customers a broad combination of:
