🔍
Incoming Material Inspection
All raw materials including copper contacts, polymer resins, and cable conductors undergo thorough inspection and testing before entering the production line to verify material specifications and quality.
⚙️
In-Process Quality Control
Continuous monitoring during injection molding, crimping, assembly, and cable extrusion processes ensures dimensional accuracy, proper contact force, and consistent manufacturing quality.
📊
Electrical Performance Testing
Every production batch undergoes contact resistance measurement, insulation resistance testing, dielectric withstand voltage testing, and current carrying capacity verification per certification standards.
☀️
Environmental Endurance Testing
Products are subjected to temperature cycling (-40°C to +85°C), damp heat testing (85°C/85% RH), UV exposure aging, and salt mist corrosion testing to verify long-term outdoor reliability.
📏
Mechanical Testing
Pull-out force testing, insertion/withdrawal cycle testing, impact resistance, and vibration testing confirm the mechanical robustness of connectors and junction boxes in field installation conditions.
