Heat Exchanger Punched Die
Laminated Evaporator Single-Progressive Die
Function
Precision one-hit stamping die that forms all critical features of a laminated evaporator plate—louvered louvers, refrigerant distribution channels, collar holes and locating notches—in a single press stroke.
Key Features
– Carbide (SKH-9 / MC53) inserts for 300 k-shot life
– ±0.01 mm blank accuracy, Ra ≤ 0.4 µm fin tip finish
– Quick-change cassette design; size swap < 10 min
– Compatible with 200–400 kN gap-frame or servo presses
– Optional in-die tapping & part marking station
Applications
Automotive HVAC laminated evaporators, battery chiller cold plates, R1234yf / CO₂ heat-pump micro-channel cores.
Continuous Fin-forming Progressive Die for Fin-and-Tube Heat Exchangers
Tool type
High-speed progressive stamping die
Strip width: 60–120 mm, thickness 0.08–0.30 mm (Al, Cu, Ni-coat Cu)
Pitch accuracy: ±0.02 mm, fin height deviation ≤ 0.03 mm
Speed: 200–300 SPM on 60–200 kN servo press; up to 7 lanes in one die
Key modules
1. Double-axis servofeed, 1–4 hole pitch step distance
2. Multi-stage louver, louvers breaking boundary layer, increasing air-side heat transfer ≈12 %
3. Micro-radius collar forming (R ≤ 0.2 mm) to maximise tube contact area
4. In-die oiling & vacuum scrap removal for burr-free edge
5. Quick-change cartridge for fin pattern swap < 10 min
Application
Condensers, evaporators, charge-air coolers, battery cold-plates for ICE & EV HVAC systems.
