Whether the project involves feeding systems, grooming products, toys, pet carriers, veterinary products, storage containers, packaging or smart pet devices, Hi-Rel Plastics & Molding can help evaluate the manufacturing process, tooling approach and material best suited to the application.
Pet products must combine durability, safety, appearance, comfort, easy cleaning and competitive manufacturing costs.
Hi-Rel Plastics & Molding works with established pet brands, startups, inventors, product developers and OEM manufacturers that require custom plastic, silicone or multi-component pet products.
Our manufacturing support can include:
Product Concept → Engineering Review → DFM → Material Selection → 3D Printing / Rapid Prototyping → Mold & Tool Manufacturing → Sampling → Production Molding → Decorating & Secondary Operations → Assembly → Inspection → Packaging
This integrated approach can help customers reduce supplier complexity and improve communication as a new pet product moves from development into production.
Controlled production environments designed to meet strict cleanliness and contamination standards.
Experience with resins suited for biocompatibility, sterilization, and regulatory compliance.
Tight-tolerance molding ensures reliable, repeatable parts for critical medical applications.
Strict quality control ensures every component meets performance and industry standards.
Custom plastic injection molding is well suited for producing durable, repeatable and attractive pet product components in a wide range of production volumes.
Potential applications include:
Injection molding can also incorporate insert molding, overmolding and soft-touch materials for products requiring metal inserts, ergonomic grips or multiple material properties.
Custom blow molding can manufacture hollow pet products, bottles, containers and reservoirs.
Hi-Rel Plastics & Molding supports extrusion blow molding (EBM), injection blow molding (IBM) and injection stretch blow molding (ISBM).
Pet care applications may include:
Blow molded components can also receive trimming, leak testing, labeling, printing, assembly and packaging depending on project requirements.
Liquid silicone rubber is increasingly used in pet products requiring flexibility, durability, sealing or soft-touch characteristics.
Hi-Rel Plastics & Molding’s LSR molding capabilities can support products such as:
LSR can also be combined with rigid plastic components when a product requires both structural support and flexible functionality.
Thermoforming and vacuum forming are economical manufacturing options for larger or thinner-wall pet products and packaging components.
Applications may include:
Thermoforming can be especially useful for larger components or production volumes where injection molding tooling may not provide the best economics.
Rotational molding is well suited for durable, large or hollow pet products.
Potential applications include:
Rotational molding can produce seamless, rugged components with integrated handles, mounting features and other molded-in details.
Successful pet product manufacturing begins with properly engineered tooling.
Hi-Rel Plastics & Molding provides mold and tool manufacturing support for injection molding, blow molding, LSR molding, thermoforming, vacuum forming and rotational molding.
Tooling support can include:
Combining tooling and production support helps reduce communication gaps between mold design and actual manufacturing.
New pet products often require design iterations before production tooling is finalized.
Hi-Rel Plastics & Molding supports product developers through engineering review and 3D printing and rapid prototyping.
Early manufacturing involvement can help evaluate:
Rapid prototypes can allow customers to evaluate appearance, fit, ergonomics and basic functionality before investing in full production tooling.
Pet products can be exposed to chewing, impact, cleaning chemicals, water, outdoor use, repeated washing and daily handling.
Hi-Rel Plastics & Molding works with a broad range of materials based on product performance and manufacturing requirements, including:
Material selection can consider:
Where a pet product may contact food or water, material requirements should be evaluated against the specific product application and applicable regulatory requirements.
Pet products are often highly visual consumer products sold in competitive retail and e-commerce markets.
Color consistency, texture, branding and surface appearance can therefore be important alongside mechanical performance.
Hi-Rel Plastics & Molding can support appropriate projects with:
Pad printing can be used for logos, product markings, graphics and other decorative features on suitable molded components.
Modern pet products increasingly incorporate molded plastics with metal hardware, cables, sensors, electronics, motors or mechanical components.
Hi-Rel Plastics & Molding can support custom plastic and metal parts manufacturing for more complex pet-product assemblies.
Potential examples include:
Combining molded components with machined metal parts, inserts and assembly services can help customers consolidate suppliers.
Hi-Rel Plastics & Molding offers assembly support for pet products requiring multiple components.
Capabilities can include:
This is especially valuable for connected pet products, automatic feeding equipment, grooming devices and other products requiring plastic housings combined with mechanical or electrical components.
Hi-Rel Plastics & Molding provides ultrasonic welding for suitable thermoplastic pet product components.
Applications may include:
Additional joining methods can include mechanical fastening, heat staking, heat insertion and adhesive bonding.
The pet-care market increasingly includes veterinary, diagnostic, monitoring and medication-related products requiring greater dimensional control and manufacturing discipline.
Potential veterinary applications include:
Hi-Rel Plastics & Molding Corp. is ISO 13485:2016 certified and offers both Class 10,000 / ISO Class 7 and Class 100,000 / ISO Class 8 cleanroom environments for qualifying products requiring controlled manufacturing.
Our cleanroom molding capabilities and clean room assembly services can support appropriate veterinary and pet-health applications.
Some veterinary, diagnostic, pet-health or high-purity pet products may require contamination-controlled manufacturing.
Hi-Rel Plastics & Molding provides:
These capabilities expand the range of pet-health and veterinary projects that can be supported beyond conventional consumer pet products.
Hi-Rel Plastics & Molding Corp. maintains:
