Case Studies
Below are how we approached several typical project types (customer information anonymized) — to help you judge whether we have handled products similar to yours.
AUTOMOTIVE / SOLENOID VALVE
Deep-Drawn Solenoid Valve Housing for Fuel Injection — Mass Production
INDUSTRYAutomotive fuel injection systems
CHALLENGEThin-wall housing required consistent wall thickness plus in-die tapping
SOLUTIONForced ironing combined with in-die tapping to reduce downstream operations
Result: stable yield in mass production, shorter lead time
SENSOR HOUSING
NOx / Oxygen Sensor Thin-Wall Housing — From Prototype to Mass Production
INDUSTRYAutomotive emission control systems
CHALLENGEVery small thin-wall housing prone to wrinkling and cracking during forming
SOLUTIONOptimized draw ratio and lubrication; multi-stage drawing with ironing
Result: prototype-to-production cycle within customer expectations
MOTOR HOUSING
New-Energy Motor Drawn Housing — Batch Delivery
INDUSTRYNew-energy vehicle motors
CHALLENGEHigh coaxiality requirement; must match downstream automated assembly rhythm
SOLUTIONDedicated draw tooling with in-line inspection, stable per-piece cycle time
Result: zero delayed deliveries across consecutive production cycles
HYDRAULICS
Hydraulic Cylinder End Cap — Seal Face Precision Improvement
INDUSTRYHydraulic systems
CHALLENGESeal-face flatness failures caused downstream pressure-test failures
SOLUTIONAdjusted sizing operation and press tonnage matching; added 100% flatness inspection
Result: flatness issues eliminated; customer pressure tests passed
Stock Parts & Samples
The following product categories are regularly kept in stock or as standard samples — suitable for early validation or small-batch urgent delivery. Exact specifications and stock levels are confirmed per inquiry.
| Product Category | Common Materials | Size Range | Status |
|---|---|---|---|
| Sensor housings | SUS304 / SUS316 | Ø6 – Ø25 mm | IN STOCK |
| Magnetic sleeves | Low-carbon steel / pure iron | Ø8 – Ø40 mm | STANDARD SAMPLE |
| Solenoid valve sleeves / magnetic isolation sleeves | SUS430 / carbon steel | Ø10 – Ø30 mm | IN STOCK |
| Washers (flat / wave / lock) | Carbon steel / stainless / brass | M3 – M30 | IN STOCK |
| Spring cups / end caps | Carbon steel / stainless | Ø15 – Ø60 mm | STANDARD SAMPLE |
