How GL Springs built an automated production line with 100% CCD vision inspection to supply 1M+ custom connector springs per month to an electronics manufacturer.

Case Details

Project Snapshot

Industry:	Electronics / electrical connectors
Component:	Custom connector (contact) springs
Volume:	1,000,000+ pcs / month
Production:	Dedicated automated line — raw material to finished part
Inspection:	100% CCD machine-vision inspection

Shanghai Guanglei Spring (GL Springs) designed a dedicated automated production line to supply custom connector springs to a joint-venture electronics connector manufacturer. The solution guarantees both high-volume capacity — 1,000,000+ pieces per month — and consistent, fully screened quality through integrated CCD machine-vision inspection, with the entire process running from raw material to finished part on a single line.

The Challenge
Supplying connector springs at scale meant meeting demands that manual production
cannot reliably satisfy:
- Massive, sustained volume — 1,000,000+ connector springs every month, on time
- Zero-defect expectation — a connector spring must ensure reliable electrical contact; a single defective part can cause a connection failure
- Tight, repeatable precision across millions of small components
- Consistent quality that sampling-based inspection cannot guarantee at this scale

Our Solution
- Built and customized a dedicated automated production line that runs from raw material through to finished spring in one continuous, integrated flow
- Integrated CCD machine-vision inspection for 100% in-line inspection — every part is checked, not just samples
- Single-line, end-to-end process that improves consistency, traceability, and lead time while removing manual-handling variability
- Line capacity engineered to sustain 1,000,000+ pcs per month

The Result
- Stable capacity of 1,000,000+ connector springs per month
- 100% CCD vision inspection on output, catching defects in-line
- Continuous raw-material-to-finished-product flow on a single automated line
- A dependable high-volume supply partnership for the customer's connector program
