Custom Precision Sheet Metal Bent Components | Internal Module Protection Housing & Support Brackets for New Energy Energy Storage & EV Charging Piles

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.

Product Overview

These custom sheet metal bent workpieces are specially developed as internal structural components for residential & commercial energy storage systems and AC/DC EV charging piles, including module protective enclosures, positioning mounting brackets, fixed support frames, isolation shielding shells and reinforcing bent plates. Designed to hold circuit boards, wiring harnesses, transformers and electrical modules steadily, they play roles in insulation isolation, structural reinforcement, vibration resistance and internal space layout arrangement inside charging & energy storage equipment.

Key Processing Challenges We Have Solved (Core Competitive Edge)

  1. Solved Thin Sheet Bending Deformation Problem

    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.

  2. Overcome Complex Multi-Angle & Deep Draw Bending Tolerance Drift

    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.

  3. Resolved Coaxial Hole Position Deviation After Secondary Bending

    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.

  4. Fixed Edge Collapse & Burr Defect on Narrow Bending Grooves

    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.

Our Factory Strength Advantages

  1. Full In-House One-Stop Sheet Metal Workflow

    Self-owned laser cutting, CNC precision bending, tapping, riveting, grinding, surface finishing workshop, no outsourcing procedures, better cost control and full production traceability.

  2. Professional New Energy Structural Component Experience

    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.

  3. Strict Batch Consistency Quality Control

    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.

  4. Flexible Customization Service

    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.

Application Scenarios

Internal structural brackets & module protection shells for 7kW/11kW/22kW AC home chargers, DC fast charging piles, household energy storage battery cabinets, industrial energy storage cabinet control modules, off-grid energy storage power station internal assembly accessories.
