Client Industry: Medical Devices
The Challenge:
A European medtech innovator needed to bring a portable diagnostic device to market rapidly. The design included a complex, anodized aluminum housing and several internal, burr-free stainless steel EMI shields and sensor contacts. They faced hurdles in finding a single partner capable of handling both high-precision CNC machining for the housing and delicate, medical-grade stamping for internal components, all while meeting aggressive timelines for prototypes and pilot production.

Our Solution:
Tingfeng Hardware engaged as a full-service partner. Our engineers conducted a concurrent DFM analysis:
-
For the CNC Housing: We optimized the design for efficient 5-axis machining, enabling single-setup production and a flawless matte anodized finish. Prototypes were delivered in 48 hours.
-
For the Internal Stampings: Our precision stamping team developed a custom progressive die to produce the thin (0.2mm) stainless steel shields with ±0.02mm tolerance and mirror-level burr control, followed by biocompatible nickel plating.
-
Integrated Coordination: A dedicated project manager ensured seamless scheduling between workshops. First-article samples were assembled in-house for fit verification before shipment.
Results & Impact:
-
Timeline Reduced by 40%: Fully assembled prototypes were delivered in 5 days; a pilot run of 500 units was completed in 12 days.
-
Cost Optimized: DFM suggestions led to an estimated 15% cost reduction for mass production.
-
Quality Assured: The perfect fit and finish provided a solid foundation for the client’s regulatory certification process.
-
Partnership Secured: The client has now entrusted us with mass production tooling and listed us as a key manufacturing partner.
Client Testimonial:
“Tingfeng’s ability to manage both complex machining and delicate stamping under one roof was decisive. Their engineering input and speed were instrumental in our successful launch.”
