PERFORMANCE PROFILE OF BUSH BELLOWS
PRODUCT : BUSH BELLOWS
MATERIAL : POLYACETAL, CELCON M90
REQUIRED ACCURACY : 14.02 - 14.10mm
NUMBER OF CAVITY : 4
AFTER SET-PROCESS, THE PART VARIATION FOUND TO BE : 14.03 to 14.08mm
DRAWING TOLERANCE : 0.08 & 0.10
VARIATION CAN BE CONTROLLED IN THE MACHINE WITHIN : 0.03mm
PROCESS CAPABILITY WAS STUDIED IN THIS MACHINE & FOUND TO BE : Cpk = 2.053
This part has been tried out in many machines including Multi stage Speed & Pressure profile machines, but could not be controlled at this level of accuracy. The Rejection due to dimensional variation was high in other machines whereas this Part was found to be 100% acceptable and the Process was found capable within 0.03 variation with the capacity index of Cpk = 2.053.
We had also sent our PROCESS CAPABILITY REPORT & HISTOGRAM CHART of this Part for you through Fax.
We take immense pleasure to thank for your High Performance Machine.
