Extreme Components,LP is a company dedicated to developing Alignment / Positioning devices for the Injection Mold Industry. We have developed a revolutionary method for self aligning locks that exhibit minimal friction and wear. The technology uses rollers instead of metal to metal frictional surfaces to align the 2 halves of the tool, without exhibiting wear over an extened time. We currently have locks with over 10 million cycles that still have "Zero Clearance " between the male and female. We have many documented cases of eliminating flash, parting line mismatch, etc. We do this better than anyone in the world.
