How We Earn Automotive Trust

Crisis-Proof Prototyping

Day 1, 14:00: Urgent Request
– OEM demands 50x LiDAR brackets in 48hr for crash test
Day 1, 18:30: AI Red Flag
– Thermal simulation predicts 0.3mm warpage at -40°C
Day 1, 21:00: War Room Activated
– CNC team redesigns fixturing + QA pre-cools material batches
Day 3, 10:00: Delivery
– Parts pass 85°C thermal soak test

Why "Industry Standard" Isn’t Our Standard

Parameter	Our Capability	Industry Average
CNC Flatness	±0.02mm (DIN 876)	±0.05mm
Injection Mold Variation	0.8% Cavity-to-Cavity	2.50%
3D Print Isotropic Strength	98% (ASTM D638)	85%

“During our Level 4 autonomous shuttle project, a last-minute design flaw threatened to delay crash testing by 6 weeks. The steering column bracket’s 0.3mm thermal expansion mismatch went undetected until final assembly. FirstPart’s team worked through the night using hybrid prototyping – CNC-machining the core from 6061-T6 aluminum while 3D printing a conformal cooling jacket in ULTEM 9085. Their DFM analysis not only fixed the issue but reduced part mass by 18%. We passed Euro NCAP validation ahead of schedule. Their crisis response? Engineering poetry.”

“Our hydrogen fuel cell prototype had persistent sealing failures at 700-bar pressures. Traditional vendors blamed ‘material limitations’. FirstPart’s QA team audited our entire process, discovering a 0.1mm radial mismatch between the CNC-machined flange and composite tubing. Using their 5-axis mill with real-time thermal compensation, they reprocessed 316L stainless steel components at ±0.008mm accuracy. But they didn’t stop there – their materials lab formulated a custom ceramic-coated gasket that withstood 50,000 pressure cycles. Now in production for our H2 hypercar line.”
