The world is shifting quickly to electric vehicles, and the charging setup must stay dependable. Discussions often center on batteries and control programs, yet the metal case around the equipment serves as a quiet protector that keeps things running safely and smoothly. A station meant to last many years in busy outdoor places needs carefully built shielding, not simply a basic metal shell.
Selecting the housing material ranks as the key step when planning an EV charger. Sheet metal holds its place as the common choice because it delivers a strong mix of durability, heat flow, and shaping options that plastic or mixed materials fall short on.
Charging points in public lots or roadside stops deal with plenty of hard knocks. Vehicles sometimes scrape them without meaning to, and daily use adds wear. The case has to remain firm to guard the fragile parts inside. San Jun Hardware uses solid cold-rolled steel, stainless steel (304/316), and 6061 aluminum alloy for the needed stiffness. We bend and weld with care to form tough frames that bear the pull from thick cables on current quick chargers.
Higher charging rates bring more warmth. Units handling 250kW to 480kW produce intense heat. Sheet metal moves heat away effectively. With help from San Jun Hardware’s design staff, we built in channels for cooling and open vents. Precise cuts create air paths, and brackets hold fans in place. This keeps power components at proper temperatures, even through nonstop use day and night.
A charger’s value shows in how well it handles weather and surroundings. Salt mist near the sea or thick dust at work sites can harm equipment quickly. The housing must stand strong like a barrier.
Mixing water with power invites danger. Outdoor units require solid ratings against dust and liquid. San Jun Hardware builds on past work with Outdoor Custom Digital Signage Shells (IP65) and IP65 Self-service Terminal Integrated Machine Shells. We use proven sealing methods on EV cases. Multi-axis CNC press brakes and exact adjustments produce close-fitting doors and smooth joints. These steps meet IP54 and IP65 levels, blocking dirt and dampness from reaching inside.
How long a station serves often ties to its outer layer. Our spraying area runs robotic powder coating lines for finishes that resist heat and sun. Near oceans with heavy salt, we suggest 316 stainless steel plus extra rust-proof steps. Stations stay clear of corrosion for over ten years and keep a clean look that matches the company’s style. Owners spend less on fixes down the road.
At San Jun Hardware, we offer more than parts—we bring focused answers from over 15 years in sheet metal work. Our 5,000-square-meter shop handles tough jobs in new energy fields.
Exact work forms the base of what we do. Machines such as AMADA CNC press brakes and 4000W fiber laser cutters give us close limits—±0.1mm on cuts and ±0.4mm on bends. We supply full OEM/ODM help that starts with Design for Manufacturability (DFM) checks. Fifty trained engineers review client plans to lower costs and move projects forward faster.
The EV field changes often, needing quick models and big output runs. Our setup shifts easily to meet special orders. Samples usually arrive in 3-7 working days without costly molds. All pieces go through a firm Quality Management System (ISO9001:2008). Checks cover every point, from steel arrival to boxed final items.
Busy factories sometimes need hundreds of housings on tight schedules. We have handled large orders for UHV projects where every bend had to match exactly. Small startup teams come to us for a few prototypes to test ideas before full launch. This range lets us fit different client stages.
Our sheet metal knowledge reaches into several modern areas, and we carry useful lessons from them into EV work.
Current chargers often act as smart spots with screens for ads and payments. San Jun Hardware makes hospital self-service kiosk enclosures and outdoor digital signage shells already. Those patterns guide our combined charger builds. We add bright touchscreens (up to 3500 cd/m²) and card units smoothly. A plain charging post turns into a multi-purpose spot that brings in added earnings.
Working from Dongguan, a busy production area, we draw on nearby suppliers for strong quality at reasonable rates. We have sent accurate cases to customers worldwide, from UHV charging pile projects in East China to shared power bank cabinets for Southeast Asian markets. Shipping plans protect big metal pieces with proper wrapping for safe travel anywhere.
Many clients face tight budgets yet need parts that meet strict overseas rules. Local material sources keep prices down while our checks match global standards. Past deliveries crossed oceans without damage, arriving ready for assembly.
Electric vehicles will spread only with a solid, lasting, and clever charging network. At San Jun Hardware, we view the metal case as the starting point for that strength. We blend careful machining, proven materials, and close client focus to supply sheet metal solutions that support future clean power. From basic power boxes to fully tailored UHV supercharging station shells, we stand prepared to shape your plans into real, finely made products.
