Vertical Lift Door Box Quenching Furnace For Small Batch Die Steel Cutting Tools

This mini vertical lift door quenching furnace is developed for small-batch production, mold trial making and laboratory testing scenarios. The overall furnace volume is compact with small internal loading cavity, matching small-size cutting tools, tiny mold inserts and sample workpiece heat treatment.

It retains the automatic vertical lift door sealing structure of large models, with smaller power occupation and lower floor space demand. It is the best choice for small mold workshops, tool processing factories and R&D laboratories that only need small batch quenching every day.

Compact small furnace cavity quickly reaches target quenching temperature with low power consumption. Mini vertical lift door realizes fast automatic opening and closing for frequent sampling of small workpieces. The small internal space shortens heating and holding time, improving efficiency for trial production and small batch processing, without energy waste of large empty furnace cavity.

1. Side-Open Box Quenching Furnace Front door loading & unloading, external quenching tank. Suitable for small-batch molds and single parts with low cost.

2. Bottom Drop Rapid Box Quenching Furnace The furnace bottom automatically descends and submerges into the quenching tank. Transfer time ≤30 seconds to avoid workpiece temperature drop and decarburization. Designed for precision alloy steel and aerospace components.

3. Trolley-Type Box Quenching Furnace Equipped with automatic loading/unloading trolley, specially for heavy-tonnage forgings, flanges and shaft parts.

4. Controlled Atmosphere Box Quenching Furnace Filled with nitrogen or methanol cracking gas for oxidation-free bright quenching. Ideal for automotive fasteners and gears.

5. Vacuum Box Quenching Furnace Sealed vacuum environment realizes zero oxidation and ultra-smooth surface finish. Applied to high-end molds and aerospace precision components.

• Compact Mini Cavity Design For Small Parts Small-size furnace chamber, specially for drills, milling cutters, tiny mold inserts and lab test samples, no waste of heating energy for small batch.

• Small Floor Space & Low Power Consumption Small overall size, easy to place in small workshop or laboratory; low rated power, save electricity for intermittent small-batch production.

Q1: What’s the difference between this small lift door furnace and large automatic lift door model?

A: This mini version has smaller cavity, lower power and smaller footprint, only for small batch cutting tools and trial samples; large models are for mass auto/mold production.

Q2: Can I use this furnace for mass production?

A: Not recommended. It is designed for small batch trial production; choose large uniform temperature furnace if you need daily mass quenching processing.
