Stress Relief Protocol
Welding creates substantial residual stresses within structural frames that cause progressive warping over time. We utilize Vibratory Stress Relief (VSR) and high-temperature furnace thermal annealing (600°C–650°C) prior to final CNC milling to guarantee long-term dimensional stability.
Robotic Laser Welding
Leveraging high-power automated fiber laser welding with continuous wire-feed technology. This yields extremely deep penetration with a minimal Heat-Affected Zone (HAZ), reducing structural distortion by up to 75% compared to manual arc welding.
Metrology & Laser Trackers
Large frame fabrications undergo inspection via Leica Laser Trackers and portable CMM arms. Real-time spatial measurement ensures position accuracy of multi-axis mounting holes, coplanarity of mounting feet, and frame squareness across 10-meter spans.

Frequently Asked Questions on Custom Frame Fabrication
Get clear technical insights regarding lead times, manufacturing capabilities, quality validation, and design optimization before initiating your purchase order.
How do you control heat distortion during welding of large structural frames?
Controlling thermal distortion requires a combined strategy: 1) Utilizing Finite Element Analysis (FEA) software to predict thermal expansion paths; 2) Designing custom rigid welding fixtures to hold key geometry during assembly; 3) Implementing symmetrical welding sequences (such as back-step and skip welding) to distribute thermal input evenly; 4) Utilizing automated low-heat robotic TIG/Laser welding; and 5) Subjecting the frame to Vibratory Stress Relief (VSR) or furnace thermal stress annealing prior to final 5-axis CNC portal machining of interface surfaces.
What is the maximum frame dimension and payload your facility can process?
Our heavy manufacturing facility is equipped with large-format 5-axis CNC portal milling machines with a maximum single-setup travel bed of 12.0 meters × 4.5 meters × 2.0 meters. Our overhead gantry cranes handle single weldment structures weighing up to 25 metric tons.
Which welding certifications and quality standards do your shop operations hold?
Our weld production lines operate under ISO 3834-2 (Comprehensive Quality Requirements for Fusion Welding) and EN 1090-2 (Execution of Steel Structures up to EXC3). Our manual and robotic welding operators are certified under AWS D1.1 (Structural Steel), AWS D1.2 (Structural Aluminum), and EN ISO 9606-1 standards.
How do you verify post-machining flatnesses across multi-meter spans?
For large frame weldments where traditional CMM beds are exceeded, we deploy Leica Absolute Laser Trackers and portable FARO Quantum CMM arms. This equipment measures coplanarity, hole position accuracy, and perpendicularity across 10-meter distances with dynamic spatial accuracy under ±0.025 mm.
What DFM feedback can we expect during the RFQ stage?
Within 24 hours of receiving your STEP or DWG files, our senior mechanical engineering team conducts a thorough DFM analysis. We review weld joint accessibility, raw material stock size availability, wall thickness transitions, stress concentrations, surface coating specifications, and suggest design modifications that reduce machining cycle time and tooling costs without sacrificing mechanical performance.

We provide a comprehensive range of in-house and partner surface finishing solutions: 1) Outdoor C5-M marine heavy-duty zinc-rich epoxy priming and polyurethane topcoat painting; 2) Architectural powder coating compliant with AAMA 2605; 3) Hardcoat anodizing (MIL-A-8625 Type III) for aluminum frames; 4) Electropolishing and passivating (ASTM A967) for cleanroom stainless steel frames; and 5) Electrophoretic deposition (E-coating) for automotive chassis components.
What are the typical lead times from CAD approval to international delivery?
Standard prototype frames take approximately 10 to 15 business days depending on complexity and material availability. Full-scale production batch runs (20–500 units) average 4 to 6 weeks. Fast-track rapid engineering services are available for urgent time-to-market programs, backed by air-freight or sea-freight logistics support.
