Hydraulic Spin Forming Machine for A/C Venturi Fan Shrouds
A custom forming machine engineered by J+H Automation Solutions to spin form venturi fan shrouds for air conditioning units — combining hydraulic forming power, variable frequency drive control, and precision die tooling for forming and screw hole punching in one workcell.
Project Overview
Inside every air conditioning unit, a venturi fan shroud shapes the airflow path around the condenser fan. The shroud's smooth, contoured profile is what makes the fan efficient and quiet — which means it has to be formed to consistent geometry, part after part, at production volume.
J+H Automation Solutions engineered this hydraulic spin forming machine to produce those shrouds. The machine spin forms each venturi fan shroud against precision die tooling and punches the screw holes used for mounting — completing both operations in a single automated workcell.
The Result
The manufacturer gained a repeatable forming process that turns out dimensionally consistent venturi shrouds ready for assembly, with mounting holes punched in position — no secondary drilling operation, no part-to-part variation from manual forming.
It's a purpose-built example of the forming and fabrication automation J+H delivers for HVAC manufacturers, where component geometry directly drives the performance of the finished unit.
Key Components & Engineering
The machine integrates three core technologies into one coordinated forming operation:
Hydraulic System
Hydraulics supply the sustained forming force needed to shape the shroud material against the die — smooth, controllable power through the full spin forming cycle.
Variable Frequency Drive
A VFD gives precise control over spindle speed, letting the machine match rotation to each stage of the forming cycle for consistent material flow and finish quality.
Precision Die Tooling
Numerous die tooling sets handle both the spin forming of the venturi profile and the punching of screw holes, so each shroud leaves the machine formed and ready to mount.
Automation for HVAC Manufacturing
Fan shrouds are one piece of a much larger picture. J+H Automation Solutions builds forming machines, conveyor systems, assembly lines, and control systems for HVAC manufacturers producing package units, condensers, furnaces, and air handlers.
From single forming workcells like this one to complete turnkey assembly conveyor systems, each solution is engineered around the component, the process, and the production rate the line demands.

Frequently Asked Questions
What does this spin forming machine do?
This machine spin forms a venturi fan shroud for an air conditioning unit. The shroud is formed against precision die tooling as it spins, and the same workcell punches the screw holes used to mount the finished shroud — combining forming and hole punching into a single automated operation.
What is a venturi fan shroud and why does its geometry matter?
A venturi fan shroud surrounds the condenser fan in an air conditioning unit and shapes the airflow path through it. Its smooth, contoured venturi profile improves airflow efficiency and reduces noise, so the shroud must be formed to consistent geometry — which is exactly what spin forming against die tooling delivers.
What technology powers this spin forming machine?
The machine combines a hydraulic system for forming force, a variable frequency drive (VFD) for precise spindle speed control through the forming cycle, and numerous die tooling sets for spin forming the shroud profile and punching its screw holes.
