Frequently Asked Questions

Q1: What materials are used for the terminal construction?

We use a hybrid construction consisting of a Brass (C3604) body for high conductivity and Phosphor Copper (C5191) contacts for superior tensile strength and elastic recovery.

Q2: How do these terminals perform in high-vibration environments?

The terminals feature a dual-beam contact design with a hyperbolic curve and strain relief crimp wings, validated to withstand 30m/s² vibration at 10-2000Hz.

Q3: What is the maximum temperature these connectors can withstand?

Our bullet terminals are designed for harsh automotive environments, exceeding 100 mating cycles at 150°C and surviving 3000 hours of thermal aging.

Q4: Are your products compliant with international automotive standards?

Yes, our terminals comply with USCAR-2, LV214, RoHS, and Reach standards, and our production is IATF 16949 certified.

Q5: What is the daily production capacity for these stamping parts?

We have a massive production capability of up to 1,000,000 pieces per day, supported by high-precision progressive die stamping.

Q6: Do you provide documentation for quality traceability?

Yes, we provide PPAP Level 4 documentation, batch-specific salt spray reports, and laser-etched QR codes for full traceability on every terminal.
