Quality



We give utmost importance to the quality . For this, we follow a well-developed Quality Assurance Program (QAP) to ensure reliability of the product.

RAW MATERIAL:

We make use of quality assured raw-material used in the Hollow Fan blades, such as fiber glass in different forms and weaves, resin components and conduct metallurgical analysis of hub assembly parts and hardware. These tests ensure adherence of the material to our stringent specifications and acceptance codes. The Resin system and Fiberglass laminates are tested to ensure the materials meet our quality requirement. These Quality Checks at receiving stage ensure specific strength of the product.

IN PROCESS:

We have a team of quality inspectors, which keeps a close surveillance at each and every stage of manufacturing. They have laid up patterns of fiber glass weaves, the mixing ratios of resin components in accordance with the design for a particular configuration of the blade with close monitoring of the resin-to-glass ratios. The Aerodynamic Design is assured with the help of profile comparator templates. To check the homogeneity of the composite structure, the LIH test is carried out. The Hub Assembly component manufacturing as per required dimensional accuracy is also checked to ensure dimensional conformity and surface finish / finish paint coating requirements.

FINISHED PRODUCT:

  • The Hollow FRP Fan Blades and Hub Assembly are balanced statically/dynamically to grade 6.3 of ISO 1940.
  • Each blade is held as cantilever beam and the aerodynamic load distribution on the blade is simulated by loading at discrete locations to ensure the strength capability of the blade and “Pass” each blade before packing for delivery. These load are increased steadily up to a proof-load, and deflections against loads are plotted for each loading point to ensure consistency in the structural integrity of each and every blade. The blade is accepted only if the deflection values fall within acceptable envelopes developed by our experts ensuring total product reliability and long fatigue life of the blades.
  • The Hub Assembly Galvanized parts and blades are all painted with Epoxy/High Solids Poly Urethane paint and hence are checked for coating thickness requirements. The Blades are Master Moment balanced to fit into the balanced hubs for a final dimensional check as per client approved Engineering Drawings.
