Quality and Testing

At TinzerMotor, our window regulators and motors undergo a rigorous four-pillar validation process to ensure they exceed OEM standards for the heavy-duty trucking industry.

We simulate a lifetime of use through Cyclic Testing, requiring every unit to complete over 15,000 continuous cycles, some more than 30,000 cycles without failure. This ensures the cables, pulleys, and motor brushes withstand repetitive daily operation. Complementing this, Material Testing verifies structural integrity. We perform tensile strength tests on steel frames and hardness checks on gears to prevent premature wear, ensuring the assembly handles heavy glass and high wind pressure.

Through this comprehensive regime, TinzerMotor delivers a high-quality, "fit-and-forget" solution that minimizes maintenance costs and keeps fleets moving regardless of the environment.
