Components like the "seat back angle adjustment latch" are examples of structural parts. Although each piece is only palm-sized, it must endure repeated stress from pressure and angular adjustments. These parts are often made from high-tensile steel sheets between 1.6 and 2.5mm thick, such as SPFH590 or 780MPa-grade hot-rolled steel. They are stamped with a 40T press using a progressive die, ensuring stable processing and high output.

Another common and in-demand part is the "seatbelt buckle base plate." It is installed between the main vehicle structure and the seatbelt buckle, and must have good torsion and tensile strength. As the material thickness is typically around 2.0mm, a 15-20T press is an ideal match. During stamping, special attention must be paid to the precision of the holes and the design of the blank-holding area on the die edge to prevent edge cracking or burrs from affecting subsequent electroplating quality.

When it comes to interior structures, the "in-car pedal support bracket" is worth mentioning, such as the mounting base for the driver's pedal or the rigid bracket behind the brake pedal. These parts have complex shapes, require multiple processes, and have a thickness of about 1.5-2.0mm. They are particularly suitable for a 40T press with a compound die for forming and blanking. The materials are often highly ductile cold-rolled steel like SPCC or SECC. If a galvanized surface is needed for rust prevention, we must ensure there is no heat accumulation after stamping to avoid micro-deformation.

The "central locking linkage plate" inside the car door, though seemingly simple, is a core component that connects the door handle to the central lock. Its moderate size and numerous holes are best suited for a 15T or 20T press for single-piece processing, balancing both precision and efficiency. These parts often use SUS430 or SPHC steel and are finished with zinc phosphate treatment or E-coating depending on the vehicle class.

The "trunk support hinge base plate," which we frequently produce for clients, is another representative example of a small-to-medium-sized part. This base plate is a load-bearing component fixed to the vehicle's rear structure, and the material is often 2.3mm thick SPFH590 hot-rolled steel. Because of the high demands on load-bearing direction and rotation angle, the processing includes stamping, tapping, and dowel pin hole processing, allowing the client to proceed directly to automated assembly.

When we talk about mechatronics, we must mention the "in-car blower motor bracket." These brackets are used to secure the air conditioning fan or module. They have very high requirements for dimensional accuracy and hole position. They are typically made of aluminum alloy or SECC, with a thickness of about 1.2-1.8mm. Since the size is not large and the shape is moderate, a 20T or 40T press can handle most processes and can be combined with in-die tapping and drawing techniques to boost output and yield.

We also have a client who regularly orders "battery fixing clasps." These parts are typically U-shaped, about 1.5mm thick, and require bending and spot welding after stamping. These parts have a high volume but do not require much pressure, so a 15T press is sufficient for mass production. The key is to have a clever die design and stable feeding to prevent displacement during processing, which could cause hole deviation.。

Beyond functional parts, components like the "door trim molding bracket" are also within our processing scope. Although these parts are for interior use, their flatness and hole distance accuracy are crucial for assembly stability and alignment with plastic snap-fits. They are often made of thin aluminum or stainless steel sheets, and a 20T high-speed press is used for high-efficiency mass production, a common request for export-oriented automotive manufacturers.

Lastly, the "rear seat fixing hook bracket" is installed at the bottom of the rear seat for quick seat removal. These parts are high-load-bearing and robust. They are often made of 2.5mm SPFC780 steel and are deburred and treated with an anti-rust coating after stamping. This type of processing is best done with a 40T press and a multi-station die to balance both output and stability.

Finally, we'd like to mention the "multi-function switch module bracket," which is frequently used in center consoles and cockpits. These parts typically have a thickness of no more than 1.2mm and require multiple holes and bending. Due to their compact structure and the need to reserve space for circuit installation, a 15-ton press with a progressive die is ideal, maintaining part precision while reducing production cycle time.
