New Energy Enclosure Production Line in South Korea

Automated New Energy Enclosure Production Line in South Korea

CNC Turret Punching and Panel Bending Solution for Battery Boxes, Energy Storage Cabinets, and Photovoltaic Brackets

A new energy equipment manufacturer in South Korea needed a more efficient and stable sheet metal production process for battery boxes, energy storage cabinets, photovoltaic brackets, pack housings, covers, and high-voltage cabinet shells.

To support the customer’s production upgrade, STON CNC provided an automated sheet metal fabrication solution integrating a CNC Turret Punch Press and a CNC Panel Bender. The new production line helped the customer improve punching accuracy, bending consistency, and automated production efficiency for new energy enclosure manufacturing.

Project Background

The new energy industry places high requirements on enclosure strength, dimensional accuracy, corrosion-resistant material processing, and production scalability. Products such as battery boxes, energy storage cabinets, photovoltaic brackets, and high-voltage cabinet shells usually include complex holes, mounting slots, ventilation structures, flanges, covers, and multi-sided bent panels.

Before upgrading the production process, the customer needed to solve several common manufacturing challenges:

• Battery boxes required accurate holes, slots, and consistent enclosure dimensions.
• Energy storage cabinets needed stable panel forming and reliable assembly accuracy.
• Photovoltaic brackets required repeatable bending angles for field installation.
• High-voltage cabinet shells required clean punching, precise bending, and strong structural consistency.
• Multi-material production involving galvanized steel, aluminum, and stainless steel required more flexible CNC equipment.
• Growing new energy orders required higher output without simply increasing manual labor.

STON’s new energy solution also identifies these industry challenges, especially multi-material processing, outdoor structural tolerances, and high-volume scaling demands for solar brackets, energy storage enclosures, and EV charging station housings.

STON CNC Solution

STON configured a production workflow based on CNC turret punching + CNC panel bending.

The CNC turret punch press processes mounting holes, ventilation holes, cable holes, connector openings, positioning holes, notches, and other functional structures on flat sheet metal parts. This helps the customer complete repeated punching and forming features with better accuracy before bending.

After punching, the CNC panel bender completes multi-side bending, flange forming, cover forming, and enclosure shaping. Compared with conventional manual bending, this process helps reduce bending variation and improves dimensional repeatability across batch production.

For new energy enclosure manufacturing, this solution is suitable for:

• Battery boxes
• Energy storage cabinets
• Photovoltaic brackets
• Pack housings
• Metal covers
• High-voltage cabinet shells
• EV charging station housings
• Solar mounting sheet metal parts

STON’s new energy workflow also recommends precision blanking through fiber laser cutting or turret punch press, followed by consistent forming through CNC panel bender or press brake, and then automated production flow through loading and unloading systems.

Results After Installation

After installing the STON CNC turret punch press and panel bender, the customer achieved a more stable, efficient, and repeatable sheet metal production process.

The upgraded line helped the customer:

• Improve punching accuracy for holes, slots, and enclosure features.
• Improve bending consistency for cabinet panels and bracket profiles.
• Reduce manual repositioning and production variation.
• Support batch production of battery boxes and energy storage cabinets.
• Improve dimensional repeatability for high-voltage cabinet shells.
• Increase production efficiency for new energy enclosure manufacturing.
• Build a stronger foundation for future sheet metal automation.

Why This Solution Fits New Energy Enclosure Manufacturing

New energy products require both structural reliability and production scalability. Battery boxes and energy storage cabinets need accurate enclosure dimensions, while photovoltaic brackets and mounting parts require consistent bending angles to support efficient field installation.

The combination of CNC Turret Punch Press + CNC Panel Bender fits this production model because it allows the customer to complete functional holes and cutouts before bending, then form enclosure structures with repeatable angle accuracy.

For manufacturers producing energy storage cabinets, battery pack housings, photovoltaic brackets, EV charging station housings, low-voltage cabinets, high-voltage cabinet shells, and outdoor electrical enclosures, STON CNC can provide a practical sheet metal automation solution based on actual drawings, production capacity, and workshop layout.

Project Value

This South Korea project shows how STON CNC supports new energy equipment manufacturers with complete sheet metal fabrication equipment, not just single-machine supply.

By combining punching accuracy, bending consistency, material adaptability, and production workflow planning, STON helped the customer build a more efficient production system for new energy enclosure components.

For new energy manufacturers planning to reduce manual work, improve part consistency, and scale output for solar, battery storage, EV charging, and electrical enclosure projects, STON’s turret punching and panel bending solution provides a reliable upgrade path.
