Precision Injection Molding
for Sensor Components
From in-house mold development through automotive-grade mass production — engineering-led injection molding for the most demanding sensor applications.
Precision
Dimensional Stability You Can Measure
Part-to-part consistency, not just first-article accuracy — engineered from mold design forward.
Mold flow simulation predicts warp before steel is cut. Conformal cooling holds cavity temperature uniform. SPC data available for customer audit — Cpk reports issued with every PPAP.

E-Tech Injection Molding Service Case of Sensor Parts
An automotive client needed a 30% smaller pressure sensor housing — without compromising seal integrity.
We redesigned the mold geometry with an FEA-validated ribbing structure and optimized gate location to eliminate weld lines.
