Double- or\u00a0triple-chamber sealed quench vacuum furnace for low pressure carburizing (LPC), including integrated high pressure gas quenching (25 bars N2), designed for high-volume production.<\/h2>\n
CaseMaster Evolution is a double- or triple- chamber vacuum furnace<\/a> configuration dedicated to low pressure carburizing with integrated high pressure gas quenching (HPGQ), <\/b>up to 25 bar nitrogen.<\/p>\n This solution is designed for applications where process cleanliness, reduced distortion and elimination of post quench washing<\/strong> are critical production requirements.<\/p>\n High pressure gas quenching enables a fully clean and integrated heat treatment process<\/strong>, eliminating oil from the production flow and supporting modern, environmentally responsible manufacturing environments.<\/p>\n [\/et_pb_text][et_pb_tabs module_class=”red-tabs eco-tab11″ _builder_version=”4.27.6″ hover_enabled=”0″ custom_css_main_element=”margin-top: 2rem;||margin-bottom: 2rem;” global_colors_info=”{}” sticky_enabled=”0″][et_pb_tab title=”Overview” _builder_version=”4.27.6″ global_colors_info=”{}”]<\/p>\n The CaseMaster Evolution (CMe) has been designed with the state-of-the-art construction and selections for two or\u00a0three chambers in\u00a0order to\u00a0provide maximum flexibility in\u00a0heat treatment and continuous batch processing. They are compatible with AMS2750 and CQI9 standards.<\/p>\n There are two types of CaseMaster Evolution:<\/strong> Process challenge High Pressure Gas Quenching (HPGQ) is the preferred choice for components requiring clean processing, excellent dimensional stability, and superior process consistency<\/strong>. Using inert gases such as\u00a0nitrogen, HPGQ eliminates the risks associated with liquid quenchants<\/strong> while providing highly controllable and repeatable cooling conditions<\/strong>.<\/p>\n The uniform cooling characteristics of gas quenching help reduce distortion and minimize post-heat-treatment machining requirements<\/strong>. When combined with vacuum carburizing or vacuum hardening<\/strong>, HPGQ delivers bright<\/strong>, clean surfaces free of oil residues and contamination<\/strong>, making it particularly attractive for precision components and automated production environments.<\/p>\n By\u00a0eliminating oil handling, washing operations, and associated waste streams, HPGQ also offers significant operational and environmental advantages. The technology supports sustainable manufacturing objectives while simplifying maintenance and improving workplace safety.<\/p>\n Process outcome [\/et_pb_tab][et_pb_tab title=”Advantages” _builder_version=”4.27.6″ global_colors_info=”{}”]<\/p>\n \/<\/span> Clean, oil-free process<\/strong> \/<\/span> Reduced distortion<\/strong> \/<\/span> Simplified production flow<\/strong> \/<\/span> Environmentally friendly operation<\/strong> \/<\/span> Ideal for precision components<\/strong> [\/et_pb_tab][et_pb_tab title=”Configurations” _builder_version=”4.27.6″ global_colors_info=”{}”]<\/p>\n This configuration is recommended when process cleanliness, reduced distortion, and elimination of oil-related operations<\/strong> are key requirements.<\/p>\n It is ideal for applications where clean surfaces, simplified production flow and environmentally responsible operation are priorities.<\/p>\n [\/et_pb_tab][et_pb_tab title=”Features” _builder_version=”4.27.6″ global_colors_info=”{}”]<\/p>\n The features below describe the construction and functional elements of a\u00a0vacuum furnace designed for low pressure carburizing with high pressure gas quenching<\/strong>, focusing on\u00a0clean operation, controlled cooling and reduced distortion.<\/p>\n Automation & Compliance<\/strong> Furnace Design & Construction<\/strong> Process Integrity & Speed<\/strong> Quenching Technologies<\/strong> [\/et_pb_tab][et_pb_tab title=”Specification” _builder_version=”4.27.6″ global_colors_info=”{}”]<\/p>\n The specification below applies to\u00a0the LPC furnace configuration with high pressure gas quenching (up to\u00a025 bar N\u2082)<\/strong> and defines the technical limits, operating parameters and available furnace sizes.<\/p>\n
\/<\/span> The two-chamber furnace, called D type, provides a\u00a0dual chamber with one for processing and a\u00a0second chamber for oil or\u00a0gas quenching.
\/<\/span> The three-chamber furnace, called T type, provides the same chambers as\u00a0the D type plus a\u00a0third pre-heating chamber that can be\u00a0used for faster processing.<\/p>\n
<\/strong>Traditional oil quenching introduces additional washing operations, oil management and environmental considerations, which may limit process efficiency and layout flexibility.
<\/strong><\/p>\n
<\/strong>The result is a\u00a0clean, repeatable and highly integrated carburizing process aligned with modern manufacturing and sustainability goals.
