Plastic Injection Molding for HVAC and MVAC Manufacturers
HVAC and MVAC plastic component manufacturing is at the core of what Cary Products does. For over 75 years, we have supplied injection molded and thermoformed plastic parts to manufacturers in the heating, ventilation, air conditioning, and mobile vehicle air conditioning industries. Our components are built to perform in demanding thermal environments, tight installation tolerances, and high-volume production schedules.
Â
If you manufacture HVAC or MVAC equipment and need a reliable domestic supplier for plastic air movement components, louvers, housings, or custom enclosures, Cary Products has the capabilities and the track record to support your program.
HVAC and MVAC Components We Produce
Cary Products produces a wide range of injection molded and thermoformed plastic components for HVAC and MVAC applications, including:
Â
- Louvers: Rectangular, round, and winged louver configurations for airflow direction and ventilation control. Available in standard sizes and custom configurations. Our patented winged louver design installs without additional hardware, reducing assembly time on production lines.
- Fans and Blowers: Custom plastic fan and blower components for air movement applications in HVAC equipment and vehicle climate systems.
- Vents and Registers: Injection molded vent and register components for residential, commercial, and automotive HVAC applications.
- Enclosures and Housings: Thermoformed and injection molded plastic enclosures and housings for HVAC equipment, air handling units, and MVAC systems.
- Ducting Components: Large-format thermoformed ducting parts and plenum components for commercial and industrial HVAC systems.
- Custom Components: Engineering support available for custom plastic parts designed specifically for your HVAC or MVAC application.
Why HVAC Manufacturers Choose Cary Products
Purpose-Built for Air Movement Applications
Cary Products was founded on air movement component manufacturing. Our louver and ventilation product lines represent decades of engineering refinement. As a result, we understand the performance requirements that HVAC and MVAC applications demand in ways that general-purpose molders do not.
Â
Injection Molding and Thermoforming Under One Roof
HVAC programs often require both small precision components and large-format enclosures or ducting parts. Cary Products operates both injection molding and thermoforming under one roof, which means we can support your full component requirement with a single supplier relationship.
Our injection molding floor operates 28 machines from 97 to 700 tons. Our thermoforming equipment handles forming areas up to 93.7″ x 45.7″ with draw depths up to 30 inches. Furthermore, our in-house tool room manages new tooling, modifications, and preventative maintenance without relying on outside vendors.
Â
Material Expertise for Thermal Environments
HVAC and MVAC components operate in environments with elevated temperatures, UV exposure, and repeated thermal cycling. Material selection is critical. Cary Products works with engineering-grade thermoplastics suited to these conditions, including heat-stabilized grades of ABS, polypropylene, nylon, and polycarbonate. Our engineering team advises on material selection based on your specific operating environment and performance requirements.
Â
ISO 9001:2015 Quality for OEM Supply Chains
HVAC OEM manufacturers require consistent, auditable production from their suppliers. Cary Products is ISO 9001:2015 certified, and our Quality Management System governs every stage of production. Specifically, this includes in-process inspections, first article inspection on new tooling, dimensional verification, and full material traceability.
For HVAC and MVAC programs that require high volume and consistent dimensional output across every production run, our quality system is built to deliver.
