Monolithic giant die casting machine not only serves for manufacturing efficiency, for the vehicle itself, because it reduces the work of stamping and welding, so it can fundamentally solve the problem of abnormal sound of the body; For safety, the integrated molding process will also bring a highly integrated modular design, is bound to crash when the safety of the body will be greatly improved.

Technician has many design considerations to deal with sudden crash safety. In the design of Model Y body structure, eight collision situations, such as forward collision, side collision and roll, are considered. Tesla can effectively conduct and consume the impact force of the collision through the ingenious body structure design, front and rear anti-collision steel beams, energy absorption boxes and other devices to protect the safety of the occupants in an all-round way.

The Model Y body adopts a steel-aluminum hybrid body frame, and the key parts are reinforced with high-strength boron steel, which can withstand larger impact forces. The integrated thermometer inner and outer door rings (boron steel), front roof beams (boron steel), and rear roof beams (high-strength steel) form a ring-enclosed structure that provides strong support for the Model Y body. The innovative structural design of laying the battery pack flat on the bottom of the car also greatly improved the overall structural strength of the Model Y, reducing the risk of rollover and side impact invasion.
