Description

AL part manufacturing equipment {AL part manufacturing equipment}

The present invention relates to an AL component manufacturing device, and more particularly, to an AL component manufacturing device that can reduce the manufacturing cost of aluminum parts required for vehicle weight reduction and improve productivity in comparison to conventional manufacturing molds. will be.

The trend of lightweight automobiles, which is strongly demanded in the global automobile industry, is emerging as a key technology that determines the global competitiveness of the automobile industry due to the strengthening of environmental and fuel economy regulations around the world. In addition, as the demand for eco-friendly vehicles such as electric vehicles and hydrogen vehicles has recently increased, related technologies for weight reduction of vehicles have received more attention.

Vehicle weight greatly affects fuel efficiency improvement and CO2 emission reduction. Automakers have been aware of its importance and have been coping with weight reduction for a long time. Recently, as air pollution has become serious, exhaust gas regulations are gradually being strengthened, and thus fuel efficiency improvement by weight reduction is considered more important than before.

The lighter the car body, the less fuel it consumes, and the less fuel it consumes, the cleaner the air and the less dependence on fossil fuels that are scheduled to run out.

In addition, although the power is changing from gasoline engines to hybrid (HEV) and EV to improve fuel efficiency, core parts such as batteries are heavy and the weight of automobiles is increasing as advanced parts and functions are added. Increasing mileage is an essential task that must be addressed without change.

In automobile weight reduction, a review of the body structure and substitution of structural materials are being carried out in many cases. Previous automobile bodies were mostly made using heavy steel materials.

Substitutes for this are aluminum, magnesium, and titanium alloys whose specific gravity is lighter than iron.

Aluminum alloy is the most suitable substitute material with strength and safety at 1/3 the weight of existing steel materials. It is already used in many parts of the car body and contributes greatly to weight reduction.
