The Project

In 2022, HH Technologies asked Form Manufacturing to develop an injection molded version of three bearings they were machining in house.  The bearings were being machined from UHMW stock and with capacity constraints and rising costs, they we’re looking for a better solution for their growth.

The Solution

Transitioning from machining to injection molding can be a challenge, particularly when there are tight tolerances involved.  These three bearings also presented the challenge of thick part cross-sections which can cause cooling and sink issues in the molding process.  To mitigate these potential dimensional challenges, Form’s engineering team redesigned the parts to maintain the critical dimensions, mating surfaces and part rigidity, but reduce the bulk of the material for consistent molding.

Manufacturing Process:  Injection Molding

Material Selected: UNMW

Key Performance Metrics
