On April 1, 2026, an Indian customer visited the Haifei factory for a two-day in-depth technical inspection and on-site sample testing of the HFTD-350-Y hydraulic copper diffusion welding machine.
On-Site Inspection: Direct Demonstration of Core Processes
Accompanied by Haifei's technical engineers, the Indian clients conducted an in-depth tour of the production workshop to witness the operation of the high-precision Medium Frequency (MF) Inverter Diffusion Welder. The delegation performed a detailed inquiry into the equipment's pressure control precision, vacuum retention capabilities, and the stability of the heating curve when processing multi-layer copper foils and flexible connectors.
Haifei's technical team demonstrated how molecular diffusion technology enables copper busbars to achieve molecular-level bonding without the addition of any solder or filler metal. This connection method not only ensures extremely low contact resistance but also delivers superior conductivity in high-current applications.
HFTD-350-Y: Synergizing High Pressure with High Precision
During the inspection, the clients specifically evaluated the performance of the HFTD-350-Y when handling large-section copper busbars and flexible connectors:
- Hydraulic Drive System: The clients observed the stability of the pressure output during the welding process. This system provides consistent and uniform mechanical pressure, ensuring perfect atomic diffusion of multi-layer copper foils under high-temperature conditions.
- 350kVA MF Inverter Power Supply: The Indian delegation expressed high praise for the heating speed and closed-loop temperature control. The 350kVA configuration ensures high thermal efficiency even when welding thicker copper busbars.
- Welding Consistency: Cross-sectional analysis of the samples revealed a void-free, high-strength molecular bond in the weld zone, with electrical conductivity nearly identical to that of the base material.
