Unique's Approach To Mold Making

This Canadian mold making shop, Unique Mould Makers, is aptly named. Virtually every multi-cavity injection mold set made for the manufacture of caps, closures, vials and other packaging applications is indeed unique. One might think that automation and standardization would not be of interest to such a shop. Think again!

Bolt-On Microfinishing

The process of microfinishing or superfinishing, as it's also known, is finding wider application in metalworking. Demands for better performance in rotating components coupled with tighter manufacturing tolerances is leading shops to look at microfinishing as a final process step to achieve low and sub-micron finishes on ground parts.

A PC In Every Pot?

There seems to be a growing movement in manufacturing, and in other industries, to recognize employees as assets. Consequently, companies are making efforts to protect and grow those assets and, more to the point, keep these assets engaged in their work so they are less likely to seek happiness at another company.

Don't Touch That Tool

Tool measurement is critical to the metalcutting process. Exact knowledge of a cutter’s length, diameter, even profile, and the ability to measure and monitor these dimensions over time, can reduce variability and help optimize the process. Here’s a look at how non-contact tool measurement and breakage detection benefit your metalcutting process.

Troubleshooting Your Way Oil System

An expensive lesson that many shops learn too late is that the automatic oil system on their CNC machine tool may not be completely automatic. Since the automatic oil system is designed to give a warning when the oil tank is empty, many machinists simply assume all is well if the alarm doesn't go off.
