Flow Analysis

 

Case Study: Blower Wheel

Challenge

High volume production with abrasive material (1 million parts per year)

Eliminate cold sprue in part center to avoid post molding operation

Fan part, requires tight roundness tolerance, rotates at high rpm in assembly

Objective

Use flow analysis to determine best fill method

Improve part design for better flow properties

Design hot runner and mold layout to allow parts to be molded in a 250 ton machine

Results

Cost savings, cold runner and secondary operations completely eliminated

Faster cycle times than center sprue gated

Perfect part dimensions achived through exact positioning of 3 nozzles

Improved cooling in part center

Return on investment for flow analysis, 1 week of production

Wear resistant Rheo-Pro® nozzle tips provide long gate life
