We specialize in custom precision sheet metal bending fabrication for energy storage and EV charger internal structural accessories. We overcome ultra-thin plate deformation, complex multi-angle bending tolerance deviation and small-position hole alignment difficulties during production. Strict dimensional consistency, flatness control and batch stability ensure your internal module brackets & protection housings fit perfectly with circuit components, supporting small sample trial orders and large-scale project mass production for global new energy manufacturers.
Ultra-thin cold-rolled steel / aluminum alloy thin plates are prone to warping and rebound after bending; we adopt customized bending die + segmented pressure forming process to control rebound value precisely, guarantee flatness within strict range after forming.
For irregular multi-bend folded brackets, traditional processing easily causes size out-of-tolerance; our pre-programmed CNC bending compensation technology keeps overall tolerance within ±0.1mm, matching high-precision assembly requirements of internal electronic modules.
Holes close to bending lines often shift position after forming; we adopt pre-bending positioning hole layout + post-forming fine calibration to ensure hole center alignment, smooth screw assembly without forced fitting.
Narrow deep bending slots tend to have edge collapse and rough burrs; we configure special small-size bending punches + full post-grinding deburring to keep edges neat and scratch-free for internal component installation.
Self-owned laser cutting, CNC precision bending, tapping, riveting, grinding, surface finishing workshop, no outsourcing procedures, better cost control and full production traceability.
Years of deep processing experience for EV charger & energy storage internal brackets & housings, familiar with internal assembly logic, heat dissipation layout and anti-interference structural design of power equipment, able to provide DFM structural optimization suggestions to reduce your assembly failure rate.
First article inspection, in-process dimensional inspection and finished full sampling measurement for every batch, effectively avoiding size fluctuation in mass production, stable delivery schedule for long-term order cooperation.
Accept drawing/sample-based OEM & ODM customization, adjustable material (SPCC, SGCC, aluminum, stainless steel), thickness, bending structure, hole position, surface treatment (powder coating, brushing, passivation), customized logo marking is available.
