Case Study Module – Medical Devices
Case Study Module – Medical Devices
Subheading: Titanium Spinal Implant
Subheading: Titanium Spinal Implant
Industry: Medical Devices
Material: Ti-6Al-4V Titanium
Part Type: Lumbar Interbody Fusion Cage
Tolerances: ±0.01 mm
Surface Finish: Ra 0.15 μm
Batch Size: 200 pcs
Customer Challenge:
The client required tight tolerances and biocompatible titanium for spinal implants. Previous vendors struggled with microcracks, inconsistent surface finishes, and excessive scrap rates.
Our Solution:
Custom vacuum fixturing for thin walls
5-axis toolpaths with mist cooling
In-process inspection with Renishaw probing
💬 Client Feedback:
"Ekinsun’s technical depth saved our Q3 release. Outstanding consistency and speed."
Case Study Module – Aerospace & UAV
Case Study Module – Aerospace & UAV
Subheading: UAV Mounting Bracket
Subheading: UAV Mounting Bracket
Industry: Aerospace & UAV
Material: 7075-T6 Aluminum
Part Type: Lightweight Mount Bracket
Tolerances: ±0.005 mm
Surface Finish: Ra 0.2 μm
Batch Size: 500 pcs
Customer Challenge:
Required high dimensional accuracy across multiple angled planes; prior vendors caused warping and inconsistent flatness.
Our Solution:
5-axis strategy to eliminate reclamping
Dynamic toolpaths to reduce thermal distortion
Structural FEM optimization for weight vs strength
Client Feedback:
"They not only machined to spec, but helped us optimize weight and rigidity."
Case Study Module – Consumer Electronics
Case Study Module – Consumer Electronics
Subheading: Smartphone Housing Frame
Subheading: Smartphone Housing Frame
Industry: Consumer Electronics / 3C
Material: Anodized 6063 Aluminum
Part Type: Smartphone Mid-frame
Tolerances: ±0.01 mm
Surface Finish: Anodized Silver
Batch Size: 5,000 pcs
Customer Challenge:
Ultra-thin wall design (0.7 mm), color uniformity in anodizing, and avoidance of scratch defects during mass production.
Our Solution:
Vacuum clamping jigs to reduce deformation
Robotic arms for handling (anti-scratch)
Controlled anodizing across matched batches
Client Feedback:
"Excellent quality control and finish. Helped us scale production confidently."
Case Study Module – Automotive
Case Study Module – Automotive
Subheading: Precision Gear Housing for EV Drivetrain
Subheading: Precision Gear Housing for EV Drivetrain
Industry: Automotive
Material: Die-cast Aluminum + Machined Surfaces
Part Type: Transmission Gearbox Housing
Tolerances: ±0.01 mm critical bore
Surface Finish: Machined + Chromate
Batch Size: 1,000 pcs
Customer Challenge:
Tight tolerance in large cast parts led to warping after machining. Alignment of shaft bores required under 10 microns.
Our Solution:
• Used 3-point vacuum fixturing and probing alignment
• Post-machining stress relief bake
• Dual-station horizontal milling for cycle efficiency
Client Feedback:
"Your CNC strategy helped us meet tolerance and cut cost across the board."
Case Study Module – Oil & Gas
Case Study Module – Oil & Gas
Subheading: Stainless Valve Body for High-Pressure System
Subheading: Stainless Valve Body for High-Pressure System
Industry: Oil & Gas
Material: 316 Stainless Steel
Part Type: High-Pressure Valve Block
Tolerances: ±0.02 mm
Surface Finish: Ra 0.4 μm
Batch Size: 150 pcs
Customer Challenge:
Deep-hole features required burr-free finish and pressure tightness. Conventional drilling caused tool deflection.
🛠 Our Solution:
Deep peck drilling strategy with low-RPM carbide tooling
Deburring by ECM post-process
Full NDT pressure test + leak inspection
💬 Client Feedback:
"Best machining vendor we’ve used for pressure-critical parts."
