1. Available dimensions for heat pipes: 1) Tube diameters: Φ5, Φ6, Φ8 (mm); 2) Effective length of the heat pipe: MAX 350 mm L, MIN 50 mm L.
2. Heating method: Dual-sided heating, crafted from premium red copper; heating length of 75 mm; temperature setting range from room temperature to 150°C; mold can be quickly exchanged (includes one set of Φ5 molds as standard).
3. Press‑fitting method: The press‑fitting mold is machined from SKD11 steel and undergoes heat treatment to achieve a hardness of HRC 45–48. The mold can be quickly replaced. (Our company provides the customer with the mold’s external dimensions and hole‑position specifications; the customer then fabricates the mold according to these dimensions.)
4. Each workstation can produce one heat pipe, for a total of four workstations.
5. There are two test modes to choose from: 1) Temperature mode: Set the time and temperature parameters to determine whether the result is NG or OK; if OK, proceed with clamping and cutting (the temperature measurement point is located above the sealing mold, at the tube‑shrinking end). 2) Time mode: Adjust the heating time setting; when the set heating time is reached, initiate clamping and cutting.
6. A hydraulic cylinder is used to perform the copper tube crimping operation, while a pneumatic cylinder cuts off the excess material from the copper end. Once completed, a downward‑acting pneumatic cylinder automatically ejects the copper tube, and an operator removes it manually. (The hydraulic power unit includes a motor, cooling fan, hydraulic cylinder, hydraulic solenoid valve, oil tank, etc.)
7. Time control via digital display on the human–machine interface, with PID temperature control displayed digitally and paired with an SSR solid-state relay.
8. The number of clamping cycles can be set; once the preset count is reached, the machine will cease operation, and the HMI will display an alert.
9. In the event of an abnormal condition, a buzzer and a red indicator light serve as alarm devices.
10. Equipment wear parts: the female and male dies used in the pressing process shall be replaced by the customer according to their service life, which depends on the number of pressing cycles.
11. Machine dimensions: 1150 mm (L) x 950 mm (W) x 2000 mm (H)
12. Working height: 1100 mm (H)
13. Voltage: 380 V, 3-phase, 4-wire, 50 Hz
14. Full-load power consumption: 3 kW
15. Air supply: 6 kg/cm² or higher, dry and clean compressed air
16. Lubricant: R32 lubricating oil
