Vacuum Furnace Solutions from ALD-Holcoft

By processing in small batch loads the SyncroTherm is capable of of one-piece-flow heat treatment and in line automation working in concert with soft machining centers and finish grind.  For the first time, this offers full integration of vacuum heat treating on the production floor.  The SyncroTherm is an excellent multi-zone furnace, able to continuously process up to 6 loads, each with independent process parameters.            

Our world known ModulTherm systems marry multiple vacuum furnace chambers (treatment chambers) to a common quench chamber. This system can also be integrated with pre and post heat treat operations like wash, preoxidation and temper. The combination results in a flexible and automated vacuum based heat-treating system designed to produce the highest quality, and highest quantity output.

The systems were originally focused on the Low Pressure Carburizing market. Acetylene based LPC was perfected along with 20 bar pressure helium gas quenching (HPGQ). Literally hundreds of these treatment chambers are in operation around the world. It didn’t take long to realize the utility of these systems in a variety of other applications including neutral hardening, vacuum brazing, nitrocarburizing and any other heat treat process performed in a vacuum. The independent treatment chambers enable multiple processes to be performed in each chamber at the same time.

We've now extended the product line by introducing vacuum oil quenching.  This addresses the market segment that cannot justify the higher alloys necessary for gas quenching.  This new capability enables the heat treater to enter into the fully automated system realm and allows the flexibility to move toward HPGQ when the market demands require it.  Modularly upgrading the system for more capability and capacity is precisely the concept behind the ModulTherm.

For some full automation is not the goal, we realize it doesn’t fit everyone’s production rates.  This is where the DualTherm comes in. It enables the lower volume heat treater to benefit from LPC and HPGQ without the need for a totally automated system. It further provides the avantages of "cold chamber quenching" and can thereby provide results equal to the ModulTherm system.  The DualTherm is now available with vacuum oil quench or a combination of vacuum oil quench and up to 2 bar gas quenching.

Finally, we round-out our vacuum furnace offerings with the MonoTherm. MonoTherm is a single chamber, single batch vacuum furnace for the most common heat treat needs. The "kit" style design enables the user to have the configuration that best suits their needs.
