生产设备

The performance and life of a fan impeller come down to a few key processes: casting or welding, heat treatment, dynamic balancing and inspection. Here is an overview of our production and testing equipment.

Main production equipment

• Aluminium melting furnace - for casting A356 / LM6 impellers, with traceable material and batch
• Annealing furnace - post-weld stress relief and casting heat treatment to reduce distortion and cracking
• Dynamic balancing machine - every impeller balanced to ISO 1940-1 G6.3, or G4.0 for high-speed and precision duty
• Press and welding jigs - steel impellers press-formed and welded on both sides, then jigged back to profile
• Turning and assembly stations - hub machining, bore and keyway fitting, run-out checked after assembly

Testing capability

• Dynamic balancing: ISO 1940-1, record issued per impeller
• Performance testing: AMCA 210-07 / ISO 5801, curves and test data available
• Casting inspection: X-ray and material certificates on request
• Dimensional inspection: bore tolerance, keyway, tip clearance checked to drawing

Other machining we do

Beyond complete fans and impellers we machine fan components and non-standard parts to drawing: hubs, flanges, inlet collectors, guards, duct connections. Send a sample or drawing for a quotation.
