DN Solutions' Electric Vehicle (EV) Component Manufacturing Solutions
When it comes to manufacturing electric vehicles involving innovative technologies and complex components, DN Solutions' solutions are designed to ensure efficient manufacturing, high precision, and strict quality assurance. These solutions focus on the two core systems of electric vehicles and their corresponding chassis components:

1. PE System (Power Electric System) – Replacing the combustion engine:

- Motor Housings & Motor Housing Covers: Machined primarily using the high-productivity horizontal machining center NHP 4000/5000 Series (featuring high rigidity thanks to a 3-point support bed and a maximum spindle speed of 15,000 - 20,000 r/min) and the high-speed tapping center T Series (equipped with a standard spindle thermal error compensation system).

- Inverter Cases & Motor Reducer Housings: DN Solutions utilizes the T Series tapping centers and the global standard vertical machining center DNM Series. These machines feature compact designs and high spindle speeds, requiring minimal floor space while ensuring easy operation.

- Support Rings & Bearing Supports: Productivity is optimized through the DNM Series vertical machining center, the PUMA V400 vertical turning center, and the PUMA 2100M high-performance horizontal turning center, which delivers powerful cutting capabilities.

2. Battery System – Replacing the traditional fuel tank:

- Battery Pack Cases, End Plates & Module Cases: DN Solutions applies the DNM Series and T Series. Key features include automatic tool load monitoring (detecting abnormal loads to prevent tool and workpiece damage) and the high-precision FANUC 31i control system.

3. Structural & Profile Components:

- Members & Profiles (Profile 1 & 2): Utilizing the VCF 850LSR II and VCF 5500L multi-purpose vertical machining centers, which specialize in long part machining and provide high operational flexibility thanks to the Dual Rotary Table / Twin spindle rotary table solution, significantly improving jig rigidity.

- Shock Towers: Applying the DVF 6500 high-precision vertical 5-axis machining center, which allows a variety of parts to be machined in one setup and is perfectly compatible with unmanned automation solutions like the LPS 5000.

- Diff Gear Housings: Precisely machined using the PUMA V Series and DNM Series, which feature a highly rigid 4th-axis rotary table.

Core Advantages of DN Solutions' EV Solutions:

- Dedicated engineering team for the EV industry: DN Solutions has prepared a special applications engineering team specifically for the EV sector since the early stages of the industry.

- Maximum efficiency with minimum workforce: By supporting automation solutions such as the Linear Pallet System (LPS), the system helps factories maximize productivity and quality with a minimal workforce, allowing them to respond very quickly to frequent changes of workpieces.

- Thorough whole-process management: Providing the best full-process service, ranging from pre-order qualification to on-time delivery and comprehensive post-delivery services, always putting the customers first
