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

产品概述

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.
