How production works

Partner lines we control — and a QC gate that answers for every batch

HSC is a custom manufacturing company: engineering, tooling specs and final inspection are run by our team; production runs on long-term partner lines in Bao'an, Shenzhen that we manage day to day. One contract, one accountable contact, factory-level process control.

Partner lines run our crimp specs and our fixtures — validated before any batch starts
Crimp-process checks (pull force / crimp height) signed off by our engineers each shift
Overmolding and injection sourced from qualified shops we approve part-by-part
Prototype cells sized for 10-piece samples and 10,000-piece batches alike
Our test gate before packing: continuity, hi-pot, pull, insertion force, salt spray, water immersion

Quality system

IQC → PQC → OQC, with records you can audit

📥

Incoming (IQC)

Every wire, terminal and housing lot checked: conductor resistance, plating, dimensions, flame class. Material certificates archived by batch.

🔧

In-process (PQC)

Crimp pull tests each shift, first-article approval, 100% continuity + hi-pot on finished assemblies.

📤

Outgoing (OQC)

AQL sampling before packing, visual + dimension check, batch test report shipped with the goods.

Test	Standard (typical)	Frequency
Crimp pull force	EIA-364-10 style	Every shift + per batch (by us)
Continuity / mis-wiring	100% fixture test	Every assembly
Hi-pot / insulation	1500 VAC 1 min (spec-dependent)	100%
Waterproof (mated)	IP67/68 immersion	Per batch sample
Salt spray	48–72 h on request	Per program
Bending life	5,000–100,000 cycles	Type test
