Defining the “stretch” mechanism in plastic injection molding machine tie bars:

Tie bar stretch can be measured with a strain gauge that is typically located on the end of one tie bar and sometimes on up to 4 tiebars. This stretch (or strain) is measured to record output data to the injection molding machine controller to get a tonnage reading from the injection press.

This plastic processing information is used with other safety mechanisms to avoid over stressing the tie bars, which can cause them to fail or break. This clamp tonnage data is also used as feedback for the high pressure injection molding process itself.

Glycon Corporation of Tecumseh Michigan USA designs and manufactures melt stream components for the plastics industry. Included in the Glycon product offering are distributive mix-melt feedscrewsbarrier feed screwsinjection molding barrelsinjection molding non-return valves, and barrel end caps.
