Stamping Parts

The Microscopic Cornerstone of Electrical Systems


As China's leading stamping parts manufacturer for low-voltage electrical equipment, HAIPART understands that each stamping component serves as a fundamental building block for current transmission, structural support, and safety protection.


Millimeter Design, Micron Control


We know that a 0.1mm deviation in circuit breaker terminals can cause poor contact, and insufficient flatness in contactor magnetic sheets can compromise electromagnetic performance. That's why we adhere to the standard of "millimeter-level design with micron-level control" to deliver highly adaptive stamping solutions.
