700 Ton Injection Molding Machine
Problem: Because
the regular tie rod on this application could never be tightened
properly,
thread galling occurred frequently. For removal, an overhead crane
was used. The nuts seized and had to be burned off.
Solution: Superbolt® Torquenuts
eliminated thread galling problems, providing accurate and sufficient
tie rod load. Because installation and removal can be accomplished
with simple hand tools, overhead cranes were no longer needed,
thus increasing worker safety.
