How to Perform Vacuum Quenching of Mold Steel

Vacuum oil quenching of mold steels typically employs a dual-chamber vacuum oil quenching furnace. The key advantage is a sufficiently high oil-cooling rate, enabling thorough hardening throughout the cross-section of thick or large molds and steels such as Cr12 and H13, while ensuring uniform hardness; this makes it suitable for the vast majority of cold-work and hot-work molds.

The VOGQ-669-2 dual-chamber vacuum furnace offers both oil quenching and pressurized gas cooling capabilities. It is primarily used for vacuum heat treatment processes—including oil quenching, annealing, and tempering—on materials such as high-speed steel, cold- and hot-work tool steels (e.g., H13, P20, D2), martensitic stainless steels (e.g., 17-4PH, SUS 630, 40X13, 95X18), elastic alloys, superalloys, and magnetic materials. The furnace is highly versatile and cost-effective, suitable for both mass production of a single steel grade and the production of diverse specifications and varieties in single-unit or small-batch quantities.

Compared to vacuum gas quenching furnaces, this system offers faster cooling rates and superior hardenability, allowing for the processing of carbon steels, low-alloy steels, and workpieces with thick or large cross-sections, thereby accommodating a wider range of materials. It features lower equipment acquisition, long-term gas consumable, and maintenance costs. Additionally, it offers shorter cooling cycles, higher loading density, and greater production efficiency; it eliminates the need for specialized high-pressure cooling gases, provides robust process tolerance, and consistently delivers higher, uniform quenching hardness.
