Challenge:

Original damaged part

Bahri faced significant issues with the longevity and performance of the original brass impellers, which led to frequent replacements and high maintenance costs. The main challenges included:  

  • Short lead times for sourcing replacements.  
  • Improving the hardness and lifetime of the impeller material.  
  • Reducing costs related to logistics, inventory, and downtime.  

Solution:

After Dynamic Balancing

Namthaja proposed the use of 3D printed stainless steel impellers. The solution involved:  

  • Reverse Engineering: The original part was reverse engineered and a digital model was created.  
  • Material Selection: Stainless Steel was chosen for its superior hardness and durability.  
  • 3D Printing Technology: The impeller was 3D printed using Selective Laser Melting (SLM) technology and then machined to the required dimensions.   
  • Increased Lifetime & Reliability: The new stainless steel impeller significantly outperforms the original brass impeller in terms of durability and reliability.   
  • Lead Time Reduction: The 3D printing process reduced the lead time by 85%. 
  • Cost Efficiency: The overall costs were reduced by 50% due to lower logistics, inventory, and downtime expenses.  
  • Enhanced Performance: The new impeller provided better performance, with improved efficiency and reduced power consumption.
