Part Geometry Causes Issues for Test Tube Rack Manufacturer

Curbell reduced scrap by supplying black acetal finished parts within required flatness tolerance

test tube trayA manufacturer of test tube racks was experiencing high scrap rates for a new design manufactured from black acetal. The part geometry included 50 holes drilled part of the way through the material.

The manufacturer had unacceptable yield loss due to parts warping during machining. This happened intermittently, with certain manufacturing lots, which made it difficult to diagnose and correct the problem.
