|
 |
OAKVILLE, Ontario, (June 29, 2009). VAC AERO has relocated its Corporate Head Office to 5420 North Service Road, Suite 205 in Burlington, Ontario. An integral part of our Thermal Processing Division’s Lean Manufacturing inspired re-organization plan requires moving our accounting, administration and executive management offices out of our production facility to free up needed plant space. The new offices are located 9 kms (5.5 miles) away from the Thermal Processing and Furnace Manufacturing facilities. The move does not involve any changes to our telephone numbers, mailing address or other contact coordinates.

The Molecule Counter, Part 1: Vacuum Gauges.
|
 |
By Daniel Herring.
Counting molecules is a job for vacuum gauges. Depending on the type of vacuum systems and the required operating vacuum level, different vacuum gauges are required, often in combination with one another, to accurately determine and/or control the vacuum level of the chamber at any given moment in time. A vacuum gauge is an instrument for measuring pressures below atmospheric pressure. There are many types, each designed... READ MORE

Partial Pressure Brazing"
|
 |
By Dan Kay.
As mentioned in previous articles, more and more brazing shops are using vacuum furnaces. These furnaces are quite complex, offering more options for heating, cooling, partial pressure, or multi-bar pressure (pressure capabilities above one atmosphere) for high-speed cooling. The overall effectiveness of the equipment, however, still lies with the people who program and run the furnaces. Figure 1 (below) shows a series of vapor pressure curves for a number of common metallic elements. Each curve shows the melting point of the element (indicated by a small circle along the curve) and, where the curve crosses the dotted line across the top of the chart...READ MORE
