MLHSF-16-3-E Multi-Level Hot Stamping Furnace – 3 Levels, 1,600 mm Blank
- Brand: OEM FURNACE
- Product Code: MLHSF-16-3-E
MLHSF-16-3-E is a 3-level electric blank heating furnace we designed for robot-loaded hot stamping (press hardening) lines. On each level one 22MnB5 blank (uncoated or AlSi coated) up to 1,600 mm long and 800 mm wide is heated to the austenitising temperature of 900–950 °C. The levels are heated independently and each has its own guillotine door; the robot works the levels in turn and feeds the press without interruption. The master model of the series is our single-level HSF furnace, built and commissioned by us and working in automotive hot stamping production; MLHSF stacks its proven heating chamber level by level.
Robot loading
An industrial robot loads and unloads the blanks. The fingers of the robot fork pass between the rows of brick supports on each level: when loading it sets the blank on the supports, when unloading it goes in underneath and lifts the blank out. Each level opening is 225 mm high for the robot fork and the lifted blank; a door opens only on the level the robot is working, while the other levels stay closed and keep heating. The front of the robot cell is protected by a light curtain.
One guillotine door per level
Each door is lifted by two pneumatic cylinders. Its rollers run in a track on a cam plate bolted to the level module; the last section of the track is inclined, so the door moves in towards the opening on the way down and clamps itself. The door is a fabricated door with a box-section frame and a stainless steel shell filled with fibre modules. Cylinders and roller tracks are inside expanded-metal guards so they can be seen from outside. The compressed air supply must be at least 6 bar.
Modular body
Each level is a separate module with its own steel casing and frame, insulation, front plate and door mechanism; the modules are bolted together through flanges and can be lifted one by one with their lifting lugs. The front plates have expansion slots for thermal growth. Each level is a separate heating zone; temperature is measured and controlled per level.
Panel and controls
A three-compartment floor-standing main panel stands next to the furnace: control, power and incoming/main switch compartments. Heating is driven per level by thyristor power controllers; control is by a PLC with a touch operator panel. The panel door carries ammeters per level and phase, manual movement buttons, automatic cycle and emergency stop. The main switch is sized to the model current.

Technical values come from our design and thermal calculations; capacities are for a single-blank charge per level and the calculated cycle time. Atmosphere control, temperature uniformity and blank distortion are confirmed in trial runs with the customer's blanks. The robot and press are in the customer's scope and appear in the images only to show the cell layout. Images are produced from the 3D design of the product.
Series
The MLHSF series has six models by blank length and number of levels: two-level (MLHSF-16/20/25-2-E) and three-level (MLHSF-16/20/25-3-E) for 1600, 2000 and 2500 mm blanks. For single-level, carriage-loaded models see the HSF series.
We manufacture the furnace together with the doors, panel and pneumatics, and install and commission it on site. We work with you on robot and press integration, other blank sizes and atmosphere (dry air / nitrogen) at quotation stage.
