Case Studies
Unmanned Cabinet Leak Test Station — Multi-Channel, Barcode Scan, MES Integration
How a precision parts manufacturer built a fully unmanned cabinet leak test station using LE embedded modules — PLC-triggered, barcode-logged, with shift-end MES data upload and zero operator intervention.
Valve Body & Hydraulic Fitting Seal Testing — 100% Dry-Air Production Coverage
How a valve and hydraulic fitting manufacturer moved to 100% production-line leak testing at up to 1200 kPa using LY direct pressure instruments with custom thread-plug fixtures.
4-Channel Optical Lens Module Airtightness — ±0.5% Repeatability
How a lens module assembly line validated airtightness on four camera modules simultaneously with ±0.5% repeatability using a custom micro-volume LM 4-channel fixture.
Smartphone & Camera IP68 Waterproof Testing — 8-Second Inline OK/NG
How a consumer electronics contract manufacturer replaced water immersion sampling with 100% inline IP68 validation at 8-second cycle time using LD differential pressure systems.
Catheter & Drug Vial Leak Testing — Sub-SCCM Detection to ISO 11608
How a medical device contract manufacturer validated catheter integrity and drug packaging seals to ISO 11608 requirements using LD differential pressure and LF mass flow instruments.
EV Battery Tray & Die-Cast Housing Leak Testing — 4-Channel, 23-Second Cycle
How a Tier 1 EV component supplier eliminated manual leak test bottlenecks with a 4-channel LM system — validating every battery tray and motor housing in 23 seconds per cycle, fully PLC-integrated.
