在新能源汽车的核心——电池系统中，电池托盘（又称电池包壳体）扮演着至关重要的“骨骼”与“铠甲”角色。它不仅是承载数百甚至上千公斤电芯模块的结构底座，更是守护电池安全、保障整车性能的一道防线。其质量优劣，直接关系到整车的安全性、续航里程、耐用性与成本。

In the core power unit of new energy vehicles - the battery pack, the battery tray is a crucial but often underestimated basic structural component. It is far from a simple "container" or "shell", but a comprehensive safety platform that integrates multiple core functions, serving as the cornerstone of battery systems and even vehicle safety.

The threshold beam of a car is a crucial structural component on the side of the body. It is not only the foot pedal for passengers to get on and off the car, but also the core safety component that constitutes the vehicle's side structure and resists side collisions. Choosing or evaluating threshold beams requires consideration from multiple dimensions such as materials, structure, craftsmanship, and compatibility with the entire vehicle.

The car collision beam is indeed "collision resistant", but its core function is not to ensure that the vehicle remains intact in high-speed collisions, but to protect the core structure of the vehicle and reduce maintenance costs at a relatively low cost in medium and low-speed collisions.

As a seemingly simple but crucial thermal management component, the core mission of a heater is only one: to efficiently export and dissipate the waste heat generated during the operation of electronic or mechanical equipment to the surrounding environment, thereby maintaining stable operation of the equipment within a safe temperature range. It can be vividly understood as the "air conditioning system" or "heat dissipation organ" of a device. Its specific functions are mainly reflected in the following aspects:

It is crucial to choose the appropriate software and master the usage skills in the design of aluminum extrusion molds.
