Die casting(Aluminium Die Casting) is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter and tin based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small to medium-sized castings, which is why die casting produces more castings than any other casting process.[1] Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.

The main control flow of the intelligent parking system is as follows (take the IC card as an example):
When the vehicle enters the market, the driver reads the IC card held by the owner's own parking yard before placing it in the card reading area of ​​the entrance control machine. If the reading card is valid, the barrier of the automatic barrier is lifted to allow the vehicle to enter and the vehicle passes through the entrance. After the automatic barrier, the brake rod falls automatically and the entrance lane is closed.
When the vehicle comes out, the driver reads the card in the card reading area of ​​the exit control machine. After the exit control machine automatically judges the validity of the card, the automatic barrier gate at the exit lifts and releases the vehicle. After the vehicle passes the automatic barrier, the brake is released. The pole automatically falls and closes the exit lane. If the parking period expires or the time-out or the IC card is invalid, the exit auto barrier is still in the forbidden state.
For owners who are temporarily parked, after the vehicle detector detects the vehicle, press an access control button on the entrance control machine to take out an IC card. The system automatically completes card reading, video recording, and release. When it exits, it reads the card on the exit control machine. Pay the parking fee, and compare the images of the vehicles at the same time. If there is no abnormal situation, the managers will open the gate and release the gate.
Two variants are pore-free die casting, which is used to eliminate gas porosity defects; and direct injection die casting, which is used with zinc castings to reduce scrap and increase yield.
Intelligent parking system V4.1 is a multi-media integrated vehicle charging management system that uses non-contact smart IC/ID cards for vehicles to enter and exit the parking lot voucher, vehicle image comparison, certificate capture, and management as the core to use the parking lot lanes. Automatic control of entrance and exit management equipment, automatic charging for on-site parking according to pre-set charging standards, and system integration of IC/ID card identification technology and high-speed video image storage and comparison technology through computer image processing and Automatic identification, comprehensive and systematic management of the charge and security of vehicles entering and exiting the parking lot.
