As a leading connector assembly manufacturer in China, HAIPART combines precision engineering with uncompromising quality control. Every assembly undergoes 12 critical inspection stages:
Raw material screening
Conductivity validation
Insulation withstand voltage testing
Temperature rise cycling
10,000+ mechanical life simulations
Digital verification of bolt torque/insulation thickness
“We digitally control even the strength of a single fixing bolt and wall thickness of insulating components to ensure customers’ peace of mind during installation and reliable operation.”
