CaseMaster Evolution® –  new generation case hardening furnaces

Double-& Triple – chamber vacuum furnace for low pressure carburizing (LPC) and oil or gas quenching in high volume production

CaseMaster Evolution “CMe” this is the family of vacuum furnaces is dedicated for semi-continuous case hardening by low pressure carburizing and oil or gas quenching as well as for through hardening as a wide alternative for atmospheric sealed quench furnaces, continuous lines and multi-chambers systems.

The CaseMaster Evolution (CMe) is a new generation of sealed quenching solutions, an additional option for a wide range of LPC applications for various industries such as aerospace, automotive, machine-building, bearings and commercial heat treatment.

The CaseMaster Evolution has been designed with the state-of-the-art construction and selections for two and three chambers in order to provide maximum flexibility in heat treatment and continuous batch processing. With dozens of CMe oil quenching vacuum heat treatment furnaces installed, SECO/WARWICK is currently at the forefront of international vacuum heat treatment market. A number of top international manufacturing companies, being in the need of superior mechanical properties, have compared the CMe with conventional case hardening methods. Having compared that, those companies have increased their production capacities with CaseMaster Evolution designed by SECO/WARWICK.

and it’s just the beginning

There are two types of CaseMaster Evolution. The two-chamber furnace, called D type, provides a dual chamber with one for processing and a second chamber for oil or gas quenching. The three-chamber furnace, called T type, provides the same chambers as the D type plus a third pre-heating, pre-oxidation chamber that can be used with PreNitLPC® for faster processing. Cooling may be carried out in two ways: under gas quenching or in hardening oil quenching. Durable graphite insulation and heating elements provide long, reliable service in this heavy-duty furnace designed for industrial applications.

The high-efficiency oil quenching has an agitation system that ensures excellent oil penetration through the workload which results in uniform and fast workload cooling. The gas system, pump system, power supply and cooling systems are generously sized to enable a wide range of industrial heat treatment implementations.
