AUTOMOTIVE & EV DIE / MOLD & PARTS FABRICATION
Overcoming EV & Automotive Tooling Challenges with Precision Engineering
From high-voltage connectors to lightweight EV structural components, we solve strict tolerance, high-wear, and thermal deformation challenges for Tier-1 automotive suppliers.
PAIN POINT 01
Micro-Tolerance & High-Pin Density Wear
The Challenge
EV high-voltage connectors and glass-filled resins (PA66+GF) cause rapid core pin wear, flash issues, and micro-cracks under high injection pressure.
Our Solution
Hardened alloy core pins with strict coaxiality (≤0.003 mm), combined with DLC / TiAlN PVD coatings to extend mold life up to 1,000,000+ shots.
PAIN POINT 02
Deep-Cavity & Thermal Distortion Control
The Challenge
Machining large, complex EV battery housings and lightweight aluminum structural molds suffers from high stress deformation and deep-cavity EDM tool wear.
Our Solution
High-speed 5-axis CNC machining with stress-relief heat treatment cycles, coupled with custom conformal cooling channels for zero-warpage production.
PAIN POINT 03
Strict PPAP Traceability & Protracted T1 Lead Times
The Challenge
OEM qualification delays due to missing material certifications, incomplete CMM inspection reports, and long prototype mold iteration cycles.
Our Solution
Rapid Tooling (T1 samples in as fast as 12 days) with complete IATF 16949-compliant PPAP Level 3 documentation, steel certs, and CMM dimensional reports.
