HVAC Component Manufacturing

HVAC and Heat Exchanger Parts – Molded Composites, Panels, and Sheets

Engineered Composites Incorporated (ECI) is a proven U.S.-based manufacturer of durable, high-performance composite parts for the heating, ventilation, air conditioning (HVAC), and heat exchanger markets. Our thermoset and thermoplastic molding capabilities support OEMs and system suppliers seeking lightweight, corrosion-resistant alternatives to traditional metals—without compromising thermal stability, strength, or fit.

Since 1994, we’ve helped HVAC product developers and heat management system designers reduce cost, weight, and complexity with engineered composite components tailored for thermal performance and long-term field durability.

A Trusted Partner for HVAC and Thermal Systems

The HVAC industry depends on materials that are resistant to corrosion, temperature fluctuations, vibration, and wear. ECI offers a wide range of composites that are dimensionally stable, non-conductive, and easy to mold into complex shapes—making them ideal for structural or functional components inside and around heating and cooling units.

We work with customers across the HVAC spectrum, including commercial rooftop unit suppliers, residential system manufacturers, industrial heat exchanger OEMs, and aftermarket parts providers.

Integrated Tooling, Machining, and Robotic Finishing

Our in-house capabilities encompass a full range of services, from custom tooling and compression molding to CNC machining, robotic trimming, and product finishing. Our integrated processes enable ECI to deliver fully finished composite parts that meet precise fitment and performance specifications – crucial for today’s complex HVAC assemblies and housing systems.

This integrated approach ensures repeatable accuracy, cost-efficiency, and optimal part performance for even the most demanding system requirements.

Composite Molding Technologies for HVAC Applications

Our material expertise and molding processes support a broad range of HVAC and heat management parts, from internal structural supports to large exterior system housings. Here’s how our core processes are applied across the industry:

Sheet Molding Compound (SMC)

Excellent for strong, corrosion-resistant enclosures and structural components:

  • Outdoor unit housings and panels
  • Access doors and mounting brackets
  • Vibration-dampening frames
  • Fan cowls and shrouds
  • UV- and weather-resistant ductwork

Liquid Composite Molding (LCM)

Ideal for lower-volume, highly contoured components with excellent surface quality:

  • Custom enclosures
  • Sensor housings and control panels
  • Heat shield covers
  • Mounting plates and airflow guides

Bulk Molding Compound (BMC)

Best for compact, high-strength parts where electrical insulation and fire resistance are key:

  • Terminal blocks and junction boxes
  • Electrical enclosures and component holders
  • Mounting insulators
  • Flame-retardant internal supports

Glass Mat Thermoforming (GMT)

Suitable for high-impact or large-format structural panels:

  • Access floor panels for HVAC service areas
  • Modular housing structures
  • Shock-absorbing supports
  • Compressor bases and risers
