Since 1978, their on-site engineering and manufacturing operations in Bremen, Alabama has produced the most respected brands within the markets that they serve.
HH Technologies promise to provide the most innovative and dependable solution to their customers extends into their three primary business divisions: RollSeal, PolarCool and OEM Services.
HH Technology also trusts Form Manufacturing with the production of product badging for their RollSeal brand. Find this, and other product emblems, in our Parts Gallery.
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
