HVAC systems depend on components that can withstand temperature shifts, vibration, and continuous operation. At Principal Manufacturing Corporation, we provide custom metal stamping, fine blanking, CNC machining, and plastic injection overmolding services tailored to the needs of heating, ventilation, and air conditioning equipment manufacturers.

With in-house tooling, integrated production, and extensive material expertise, we help HVAC OEMs bring durable, cost-effective solutions to market.

Common HVAC Applications

We manufacture precision parts used in residential, commercial, and industrial HVAC systems, including:

  • Compressor and condenser brackets
  • Fan blades and motor mounts
  • Ductwork support components
  • Housing and enclosure hardware
  • Control panel backplates
  • Sealing and insulation interfaces
  • Airflow and damper mechanisms

Built for Reliability and Repeatability

Our processes are optimized to ensure dimensional stability, corrosion resistance, and long-term performance. We offer:

  • Progressive die metal stamping for complex geometries at scale
  • Fine blanking for tight-tolerance components that require minimal finishing
  • CNC machining for critical sealing surfaces or connection points
  • Plastic overmolding for parts that demand vibration dampening or thermal insulation
  • Assembly and finishing for ready-to-install components

Our integrated capabilities help reduce part handling, shorten lead times, and streamline your supply chain.

We are certified to IATF 16949:2016 and ISO 14001:2015, with robust quality systems in place to ensure that every HVAC component meets your engineering and compliance requirements.

We also maintain ITAR compliance to support sensitive applications that demand process control and traceability.
