As the world shifts faster toward renewable sources, much attention goes to battery improvements and control software. Yet the outer case—the enclosure—plays a quiet but vital role in how long and how well the whole setup lasts. In new energy power systems, this case is not just a basic cover. It forms a carefully built part that handles heat removal, keeps electricity safely contained, and stands up to tough conditions for many years.
San Jun Hardware, a sheet metal specialist started in 2010, has grown into a key supplier for this field. The company runs a 5,000-square-meter plant with a staff of 50 skilled structural engineers. We supply the strong protection required for modern power equipment.
Systems like solar inverters and outdoor power boxes often sit in places open to rain, dirt, and big temperature swings. A solid enclosure keeps inner parts—such as circuit boards, sensors, and fast processors—safe from early breakdown. Careful making means every edge and connection fits exactly. This builds a shield that follows strict industry rules.
High-power setups, especially storage units and quick chargers, produce a lot of heat. Good case design includes inner supports and airflow paths. San Jun Hardware excels at building metal shells that stay firm yet allow heat to escape well. We use accurate laser cuts to form vent patterns and holders for cooling parts like fans and heat sinks.
Among the toughest uses today are ultra-high voltage EV chargers, often rated from 250kW to 480kW. These stations manage thick cables and need strong insulation while running around the clock in busy spots like highway rest areas.
San Jun Hardware creates tailored sheet metal parts for such chargers. In a 480kW project in East China, the team applied 8-axis CNC bending and exact welding to handle salty coastal air. Choosing materials like 316 stainless steel and 6061 aluminum alloy led to full approval in checks. The finished units showed lasting strength against wind and rust in real outdoor service.
Each power project comes with its own space limits and working demands. San Jun Hardware offers full OEM/ODM help, covering everything from early drawings to large runs. Our engineers review designs for easier making, which cuts costs and speeds up launch times. Simple brackets with odd angles or multi-piece assemblies pose no issue. The setup handles small test batches and big orders alike without costly tools.
Picking the right metal forms the base for how well a case performs over time. San Jun Hardware works with various types, such as cold-rolled steel for shaping ease, galvanized steel for regular outdoor duty, and higher grades of stainless steel or aluminum for demanding jobs. In areas with heavy salt or factory fumes—like near-shore wind sites or seaside chargers—extra surface layers prove essential.
The Spraying Department adds the final guard coat. Options include powder coating, fluorocarbon spray, or anodizing. These finishes do more than look good. We create a tough, even surface that fights scratching and weather damage for years.
Outdoor gear often needs at least an IP65 rating, meaning full dust block and resistance to strong water sprays from any side. Reaching this calls for very close work, especially on door edges and rubber seals. San Jun Hardware relies on multi-axis CNC brakes (including AMADA EM2510 models) and fine adjustment tools. Even bent or shaped sections end up with tight, reliable seals.
In the quick-changing new energy field, fast response gives an edge. San Jun Hardware replies to requests promptly, usually with price quotes in 24 hours. Sample parts come ready in 3 to 7 working days after drawings get approval. This quick turnaround lets customers test and adjust ideas before full production starts.
Serving buyers worldwide demands steady, high standards. San Jun Hardware follows a Quality Management System built on ISO9001:2008 (GB/T19001-2008). The approach means clear rules for all steps and accountability at every level. Checks start with incoming metal and continue through weld inspections and final coating measurements.
Finished items carry approvals for CE, RoHS, and EU safety rules (including LVD and EMC). These marks help customers bring complete systems to market more easily. The focus on strong, fairly priced work has built lasting ties with major brands and public projects around the world.
In new energy power setups, the outer case stands as the main shield. It blends clean modern looks with practical toughness. San Jun Hardware shows how skilled metal work, varied material choices, and close customer support turn a supplier into a true partner for energy progress. Picking an experienced maker familiar with high-voltage and outdoor challenges means the inner technology stays guarded by a case as advanced as the parts it holds.
A: Yes. We design custom sealing structures using high-quality gaskets and silicone, verified through rigorous water and dust testing to meet IP65/IP66 requirements.
A: Samples are generally ready within 3-7 working days. Mass production typically takes 15 to 20 days after the deposit is received, depending on the order complexity.
A: Absolutely. We provide full OEM/ODM technical support, including DFM optimization and specialized solutions for high-voltage systems and intelligent self-service terminals.
A: We primarily use 316 stainless steel and 6061 aluminum alloy combined with specialized powder coatings or anodizing for superior salt-spray and corrosion resistance.
