Challenges & Solutions For Transmission Housing

  • 01

    Porosity Elimination

    We utilize vacuum-assisted high-pressure die casting to pull air from the mold cavity, completely eliminating internal micro-porosity and ensuring high-pressure hydraulic fluid containment.

  • 02

    NVH Dampening

    Our engineering team utilizes finite element analysis to strategically add structural ribbing, effectively dampening gear-mesh vibrations and reducing airborne cabin noise significantly.

  • 03

    Precision Alignment

    We utilize high-precision horizontal machining centers to secure true position tolerances under fifty microns, preventing premature bearing wear and gear backlash errors.

  • 04

    Thermal Dissipation

    We cast integrated, thin-walled cooling channels with high-thermal-conductivity aluminum alloys, accelerating heat transfer away from the internal geartrain under maximum torque loads.

  • 05

    Galvanic Corrosion

    We apply automated, specialized conversion coatings to the mating surfaces, creating an inert chemical barrier that prevents corrosion between aluminum and steel fasteners.
