SanJun Hardware provides one-stop OEM & ODM non-standard sheet metal customization service for blade battery metal boxes and new energy storage chassis shells, covering full production procedures including laser blanking, CNC precision bending, reinforced full welding, customized heat dissipation structure, sealing groove processing, electrostatic anti-ultraviolet powder coating and finished product full inspection.
Core Competitive Advantage: Free Custom Drawing Design (No Client Self-Designed Drawings Required)
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.
Key Industry Difficulties We Fully Overcome
- Low structural rigidity & cabinet deformation under heavy load: Adopt thickened steel plate + built-in multi-layer reinforcing rib structure, enhance overall bearing capacity, effectively avoid sagging and permanent deformation after long-term placement of blade battery packs.
- Weak waterproof, dustproof and salt fog resistance: Optimized integrated folded edge + full-circle double EPDM sealing strip design, stably reach IP54/IP65 protection grade; support hot-dip galvanizing + double-layer weather-resistant coating, suitable for coastal, high-temperature, rainy and dusty harsh outdoor environments.
- Uneven assembly gaps & inaccurate hole positions: Strict precision machining control with standard tolerance ±0.1mm, high-precision customized tolerance up to ±0.05mm, ensure perfect matching of door panels, mounting holes and heat dissipation components, convenient for automatic assembly of battery modules.
- Poor heat dissipation leading to battery safety risks: Customized open/closed air duct, layered ventilation and heat dissipation window structure according to battery heat generation parameters, reduce internal temperature rise and avoid overheating failure of blade batteries.
- Single specification, unable to meet differentiated non-standard demand: Support fully personalized non-standard customization in size, thickness, surface color, lock structure, wiring hole position, installation bracket and anti-theft design, no MOQ limit for small batch trial orders.
Raw Material & Manufacturing Standard
We supply multiple material options to match different usage environments: cold rolled steel, galvanized steel, SUS304/SUS316 stainless steel. All semi-finished products go through deburring, rust removal, surface passivation and high-adhesion powder coating; finished products pass full dimensional inspection, sealing test and load test before delivery. Our factory holds ISO9001 quality management system certification, all products meet RoHS environmental standards.
