Key Applications of Servo Precision Presses in the Automotive Parts Sector

The application of servo precision presses in the automotive parts sector is expanding from traditional general-purpose stamping to the production of high-precision, high-value-added core components. This shift is particularly focused on two areas: core components for new energy vehicles (NEVs) and structural parts made of high-strength steel. The following insights are provided by Jianlong Hydraulic Technology; please feel free to contact us for more information.

1. Core Components for New Energy Vehicles (High-Growth Sector)

This represents the most significant growth market for servo presses in recent years, demanding extremely high levels of precision and process control:

1.1 Metal Bipolar Plates (Hydrogen Fuel Cells): Stamping micro-channels into ultra-thin sheets and controlling forming depth requires the high rigidity and precision of servo presses to ensure the stability and consistency of channel formation—a level of precision difficult for traditional presses to achieve.

1.2 Battery Casings and Cover Plates: The stamping production of components such as battery casings and cover plates for NEVs is another major application area for servo presses.

2. High-Strength Steel Body Structural Parts and Body Panels

In response to the trend toward automotive lightweighting, servo presses offer distinct advantages in forming high-strength steel sheets:

2.1 Body Structural Parts: Suitable for processing structural components from high-strength steel; compared to traditional presses, actual production efficiency can increase by approximately 1.5 times.

2.2 Large Sheet Metal Forming: Suitable for processes such as deep drawing, forming, blanking, punching, and trimming. They align perfectly with the modern trend of using lightweight, high-tensile steel sheets and are the preferred equipment for forming large workpieces.

2.3 Hot Stamping: Amidst the trend toward vehicle lightweighting, servo presses meet the rigorous requirements of hot stamping—specifically the need for sustained pressure—thereby improving yield rates and reducing mold damage. 

3. Precision Functional and Structural Components

The high-precision characteristics of servo presses enable the production of precision components that are difficult to manufacture consistently using traditional mechanical presses:

3.1 Transmission and Safety Systems: Small precision parts—such as seat adjustment gear plates, seat recliners, seatbelt buckles, and brake shoes—require high precision and consistency, making them ideal for servo-controlled fine blanking processes.

3.2 Engine and Steering Systems: Precision press-fitting of automotive engine components, drive shaft assemblies, and steering gear assemblies represents another typical application for servo presses.

4. Application Value Derived from Servo Precision Press Process Advantages

The ability of servo presses to expand into these applications stems primarily from their process flexibility:

4.1 Enhanced Material Formability: By pausing and maintaining pressure at the bottom dead center (BDC), the steel and alloy layers of bimetallic composites (such as half-shell bearings) have sufficient time to flow. This resolves issues like voids at the bonding interface and uneven wall thickness; the resulting high dimensional precision can even eliminate the need for subsequent fine-drawing operations.

4.2 Significantly Improved Yield Rates: In one case, a deep-drawn component had a defect rate of up to 50% on a mechanical press; after switching to a servo press and adjusting the forming cadence, the defect rate dropped to near zero.

4.3 Multi-Process Integration: A single high-tonnage servo press can integrate operations that previously required multiple machines—such as blanking, forming, coining, and punching—enabling complete processing on one unit through the use of transfer tooling.

In summary, the application of servo precision presses in the automotive sector has shifted from merely "replacing traditional presses" to "enabling processes that traditional presses cannot perform or cannot perform well." Their core value lies in three areas: forming precision components for new energy vehicles, processing high-strength steel, and integrating complex manufacturing processes.
