Description

Technical Specifications & Thin-Walled Structural Engineering

Parameter / Process

Specification & Technical Highlights

Customer Benefits / Value

Material

Grade 45# Carbon Steel (AISI 1045 / Medium Carbon Steel)

Offers excellent tensile strength, high fatigue life, and robust structural durability to withstand continuous outdoor wind loads and tracking torques.

Application Scenario

Photovoltaic Solar Power Generation Equipment / Tracking Systems / PV Inverter Mounts

Purpose-engineered to deliver high structural stability and rigid mounting interfaces for large-scale solar array hardware.

Unit Weight

4.443 kg (Large-Scale Heavy-Duty Frame)

Mass-optimized design that integrates high component rigidity within a reduced-weight framework for modern green energy engineering.

Structural Profile

Large Thin-Walled Matrix with Strict Flatness Control

Maximizes space efficiency and reduces dead-weight while ensuring pristine, unwarped structural profiles.

Coring Technology

Embedded Ceramic Core for Cylindrical Hole

Prevents core shift or inner diameter distortion during high-temperature pouring; creates perfectly uniform, clean, and smooth cylindrical bores.

Deformation Defense

Proprietary Post-Cast Tooling for Shape Rectification

Tailored cooling and press-shaping tooling guarantee absolute flat surface contact, completely eliminating structural warping.

Casting Tolerance

ISO 8062 (GB/T6414) CT6 Grade

High near-net-shape accuracy simplifies immediate assembly line integration and minimizes expensive large-face milling setups.

Advanced Rigidity & Structural Flatness Quality Control

Because solar tracker and mounting components undergo massive environmental loading over 25+ year lifespans, we apply a zero-compromise precision screening:

  • Absolute Flatness Profile Audit: 100% verified using precision knife-edge straightedges or CMM (Coordinate Measuring Machines) to ensure the large plate-like surfaces adhere strictly to your blueprint flatness tolerances.
  • Ceramic Core Cylinder Metrology: Checked via calibrated plug gauges to verify that the embedded-core cylindrical holes maintain perfect diameter sizing and straightness.
  • Subsurface Structural Density Check: Processed via Magnetic Particle Testing (MPI) or Liquid Penetrant Testing (LPT) to ensure the wide, thin-walled face is 100% solid, free of cold shuts, thermal tearing, or hairline cracks.
  • Mechanical Integrity Testing: Microstructure and hardness parameters are verified to ensure that the 45# steel delivers optimized structural load capacity under fluctuating outdoor temperatures.

Custom OEM / ODM Services for Global Renewable Energy Developers

  • Complex Large-Frame Engineering: We specialize in casting oversized, thin-walled multi-functional mounts, solar tracker joints, and inverter housings based on your 3D digital technical data (STEP, IGES).
  • Ready-for-Assembly Finishing: Equipped with large CNC machine centers to provide custom counterboring, precise face milling, or protective surface finishes (such as Hot-Dip Galvanizing or Electrophoretic Coating) for harsh outdoor environments.
  • Full Industrial Compliance: Complete material test sheets (EN 10204 3.1) stating carbon element analysis, hardness records, and flatness checklists accompany every shipment.
