Project Summary
The customer required thin precision components for a simulated test fixture, used to validate suction performance during the testing stage.
Although initial drawings specified tight tolerances and stainless steel material, the parts were not intended for final production, making cost efficiency a key consideration.
Our engineering team worked closely with the customer to redefine the true functional requirements and deliver a precision-focused, cost-optimized solution.
Key Requirements
- Thickness: 2.6 ± 0.05 mm
- Parallelism: ≤ 0.05 mm
- Flatness: ≤ 0.05 mm
- Surface Roughness: Ra 0.4 μm
• Stable performance for testing and validation
Engineering Challenges
- Original material (4Cr13 stainless steel) only available from 6 mm thickness
- High material waste and machining cost for thin components
- Simultaneous control of thickness, flatness, parallelism, and surface finish
- Strict precision needed only on functional surfaces, not full geometry
Our Solution
Material Optimization
We recommended Q235B carbon steel as an engineering-approved alternative, offering excellent machinability and significantly lower material cost while fully meeting test-stage requirements.
Process Strategy
- Laser cutting for external profiles to reduce machining cost
- Precision surface grinding to control thickness, flatness, and parallelism
- Nickel plating for corrosion protection
- Post-plating calibration to ensure final flatness accuracy
Results
- Thickness: 2.6 ± 0.05 mm
- Parallelism: 0.03 mm
- Flatness: 0.04 mm
- Surface Roughness: Ra 0.35 μm
50% total cost reduction
30% shorter lead time
Delivered ahead of schedule with stable test performance
Value Delivered
- Engineering-driven cost optimization
- Precision applied only where functionally required
- Faster delivery for test and validation projects
- Reliable support for non-standard and prototype components
