Gear Strip Chart
This is a sample strip chart of an injection molded gear achieving AGMA 11+. It was made of an acetal material with a very high shrinkage rate. This plastic molded gear has no weld-lines and required no secondary machining. It's ID was molded with a .0004" total variance of its diameter. Incredibly, the start to part time for this project was only 17 days. The tool built is capable of producing over one million of these plastic gears.
