TCI News - Inventory Management
Did you know?
We listened and we've updated our website! Our site was a bit outdated and difficult to navigate. Our new site has a new look with much of the same content, and it's much easier to find your way around.
We've also added a Photo Gallery which we will be expanding soon with more of our work. In addition, we've linked up more of our press releases and articles in our Press Room.
As always, if you encounter any issues with the site, please send feedback firstname.lastname@example.org.
"Inventory Management as Musical Chairs"
Remember when, as kids, we would play the game of "musical chairs"? When the music started, we walked in a circle as someone removed one of the chairs. When the music stopped, inevitably someone was left without a seat. I sometimes feel that we're playing that game; but oddly, in reverse. Who will be left sitting on unwanted inventory?
The recession has given the metal service center industry a refresher course in inventory management and it's not metal-specific. According to the November issue of Metal Center News, distributor inventories of aluminum are down an average of 42% from a year ago and steel inventories are down an average of 46%. One can safely assume similar conditions for inventories of other metals. Now that inventories are slowly approaching a state of equilibrium, distributors will be reluctant to add significantly to their stocks.
The mills, in turn, produce mostly for production and partly for depot stock. As distributors have turned to depots to replenish low inventories, purchasing low volumes of standard items, mills are likewise reluctant to add to expensive depot stocks preferring to run more profitable production orders that can be shipped relatively quickly. As depot stocks are depleted, mills will likely leave them as close as possible in that condition.
Our customers have been demanding smaller, more frequent shipments for many years now. In a low-demand environment like today's, that is the rule rather than the exception. And their customers are just as reluctant (and, ok, sometimes absolutely unwilling) to sit on inventories whether in raw, WIP or finished goods.
What I know to be reality is that the supply chain will be leaner moving forward. What I hope to be just as true is that customers and suppliers will likely learn to work more closely with each other so that, in my backwards game of "musical chairs", no one part of the supply chain will be left sitting on the "inventory chair".
This Month's Featured Process - Turning
Unlike conventional turning, which usually requires two operations per blank, TCIís turning economically produces close tolerance rings and circles in a single operation.
Precision turning reduces ring and circle premachining costs up to 50% and provides dimensional tolerances to ±.001", concentricity within .001", and surface finishes to 32 Ra.
TCI vacuum chucks blanks into position for turning. As the chuck rotates, the tool plunges into the blank and creates a complete, close tolerance ring or circle in up to half the time of conventional methods.
Plus, part-to-part consistency is significantly improved and the number of operations and set-ups is reduced.
