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: production ran to the confirmed schedule for this program; delivery performance is monitored against the agreed production plan
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 |
| Motor end caps / fan covers | Carbon steel / aluminum | Ø40 – Ø120 mm | STANDARD SAMPLE |
If your product is close to the stock range above, request a sample first to verify size and material suitability — then decide whether custom tooling is needed.
Deep drawing technical guides
Written for engineers and buyers rather than for search engines: how the material actually behaves, which numbers decide manufacturability, and what goes wrong when they are missed.
Deep drawing: the complete technical guide
Draw ratio, blank size, draw force and clearance — the four calculations that decide how many draws your part needs.
Deep drawing vs press forming
Which process the geometry actually needs, and how much secondary machining drawing can remove.
Deep drawing materials
Steel, stainless, aluminium, brass and copper — and the formability each one actually offers.
Ironing and wall thinning
How a thinned wall holds the inside and outside diameter without a turning operation.
Deep drawing defects and remedies
Wrinkling, tearing, earing and thinning: what causes each one and which tooling change fixes it.
Precision deep drawn components
What we make, the capability envelope, and how a project moves from drawing to production.
