Case Study

Challenge:
A customer was losing market share due to the high cost and variable quality of an intricate, internally threaded part. The product was originally being manufactured elsewhere using a manually run injection mold.

Solution:
Face-to-face and on-line collaboration provided meaningful insight to the customer's needs. Key part design modifications were jointly developed and agreed upon before proceeding with new tooling. The mold was ultimately configured to be fully automatic with three unscrewing core pins controlled by an ancillary PLC computer. The initial mold sampling produced "parts-to-print" that were delivered to the customer within hours.

Results:
Working hand-in-hand with the customer’s project engineer produced a superior product and injection mold which restored market share by cutting cycle time 300%, improving assembly efficiency 60% and reducing overall cost by more than 35%. The customer’s expectations were exceeded in every way – ease of doing business, on time and within budget.
