SanJun Hardware is a professional non-standard precision sheet metal processing factory based in Rugao, specializing in customized metal housings for blade battery packs and new energy energy storage chassis for global new energy enterprises.
Most overseas buyers face huge troubles when customizing non-standard battery cabinets: lacking structural design drawings, high independent design costs, poor cabinet structural strength, insufficient outdoor waterproof and anti-corrosion performance, and inconsistent assembly gaps. We completely solve these industry pain points with our exclusive service: completely free production-ready CAD drawing design, customers do not need to provide any self-drawn drafts.
Our full-process sheet metal workshop realizes integrated production from laser cutting, CNC bending, full penetration welding to weather-resistant surface coating, with machining tolerance controlled within ±0.05mm~±0.1mm. All non-standard blade battery boxes and energy storage chassis comply with ISO9001, RoHS and IP protection standards, widely applied to household energy storage, industrial & commercial energy storage, new energy vehicles, RV power supply, off-grid solar energy storage and other global scenarios.
Non-standard energy storage battery housings have highly differentiated internal layout, size and structural requirements. Many overseas customers cannot launch projects smoothly due to the lack of professional cabinet design drawings, and hiring industrial designers will bring extra high costs and long waiting cycles.
SanJun Hardware’s senior structural engineers provide zero-cost drawing customization service for all clients: according to your blade battery size, internal module layout, required IP waterproof grade, installation mode and operating environment, we independently complete 2D engineering drawings and 3D simulation models, support unlimited revision until matching your production demand. This service greatly saves your design expenditure and shortens the whole product development cycle.
