Industry Pain Points & Our Solutions

The rapid evolution of the EV and battery manufacturing industry presents significant production challenges. Are you facing any of these common hurdles?

Difficulty in Achieving Precision and Consistency

The Problem: Battery terminals, motor laminations, and other intricate components demand microscopic tolerances. Traditional punch presses often fail to deliver the precision needed, leading to high scrap rates and inconsistent quality.

Our Solution

Our servo presses utilize a closed-loop control system, ensuring micron-level accuracy. By precisely controlling the ram’s motion and position, our machines eliminate processing errors, guarantee part-to-part consistency, and drastically reduce waste in your battery component manufacturing.

Material Forming Challenges & Springback Issues

The Problem: High-strength steel and aluminum alloys used for battery housings and structural parts are prone to springback, cracking, or tearing during deep drawing. This compromises both the aesthetic and structural integrity of the final product.

Our Solution

Our servo presses feature unique “swing stamping” and “multi-stage forming” functions. This allows you to customize the ram speed and pressure to match the material’s properties, effectively eliminating springback and cracking. For heavy-duty deep drawing, our hydraulic presses offer the immense, stable pressure required to form thick or high-strength steel EV body parts perfectly.

High Energy Consumption and a Noisy Work Environment

The Problem: Traditional punch press machinery operates with high energy consumption and significant noise output, failing to meet modern standards for green manufacturing and occupational health.

Our Solution

Our servo presses are powered by highly efficient servo motors that only consume energy during the stamping process. This can lead to energy savings of up to 50% compared to conventional presses. The reduced noise and vibration also create a safer, more comfortable work environment, helping you achieve your sustainability goals.

Lack of Production Flexibility and Slow Changeovers

The Problem: The EV market is dynamic, with frequent model changes that necessitate highly flexible production lines. With traditional presses, adjusting parameters and changing dies is a time-consuming process.

Our Solution

The stamping parameters on our servo presses are fully programmable and can be saved within the control system. Operators can quickly switch between different product runs by simply recalling a preset program, dramatically reducing changeover time. This flexibility is essential for handling multi-variety, small-batch to mass production runs.

The Power of ChangDuan Servo Press in EV & Battery Production

Unmatched Precision and Repeatability for Critical EV Components

Achieve micron-level accuracy on every single stroke, a non-negotiable requirement for vital EV parts such as battery cell terminals, EV motor laminations, and high-density connectors. Our advanced closed-loop control system constantly monitors and adjusts the ram's position, ensuring exceptional part-to-part consistency and drastically reducing scrap rates. This superior precision directly translates to enhanced battery performance and motor efficiency in the final EV product.

Advanced Programmable Control for Complex Material Forming

Our servo presses offer highly flexible and programmable ram motion control, allowing you to fine-tune the stamping curve, velocity, and force. This is critical for working with challenging materials like high-strength steel (HSS), aluminum alloys, and specialized nickel-based alloys used in battery enclosures. Features such as "swing motion" and "multi-stage forming" minimize material springback and prevent cracking, ensuring optimal formability and structural integrity for intricate EV structural parts and battery pack housings.

Superior Energy Efficiency and Sustainable Operation

Committed to green manufacturing, our servo press technology dramatically reduces energy consumption. Unlike conventional mechanical presses that run continuously, our servo drives only draw power during the actual work stroke. This intelligent energy management can lead to up to 50% energy savings, significantly lowering your operational costs and carbon footprint. Furthermore, their low noise and vibration levels contribute to a quieter, safer, and more comfortable working environment, aligning with modern industrial sustainability goals.

Enhanced Production Flexibility and Rapid Die Changeovers

The dynamic nature of the EV market demands agility. Our servo presses are designed for maximum production flexibility. With intuitive HMI interfaces, operators can store and instantly recall a multitude of stamping programs for different EV components. This drastically reduces die changeover times and streamlines production adjustments, making our machines ideal for both high-volume production and multi-variety, small-batch manufacturing scenarios prevalent in electric vehicle powertrain and battery module assembly.
