Forging further refines material density and enhances toughness, particularly for components subject to high dynamic loads. This selection is based on Finite Element Analysis (FEA) to determine optimal stress distribution.
3. CNC Machining & Fabrication: Utilizing advanced 5-axis CNC machining centers, all critical components are machined to exact tolerances (typically ±0.02 mm or better). This ensures superior surface finishes (Ra 3.2 or finer where specified) and perfect alignment of all moving parts, crucial for smooth automatic operation and extended bearing life. Fabrication of larger structural frames involves cutting, bending, and shaping in a climate-controlled environment to prevent material distortion.
4. Welding & Assembly: Certified welders (to ASME Section IX and EN ISO 9606-1 standards) perform all welding using techniques such as Gas Tungsten Arc Welding (GTAW/TIG) for stainless steels and Gas Metal Arc Welding (GMAW/MIG) for carbon steels. Post-weld heat treatment (PWHT) is applied where necessary to relieve residual stresses. Non-destructive testing (NDT) methods, including ultrasonic testing (UT), magnetic particle testing (MPT), and liquid penetrant testing (LPT), are performed on all critical welds.
5. Surface Treatment & Coating: Components undergo thorough surface preparation, including grit blasting to SA 2.5 or SA 3.0 standards, to ensure optimal adhesion for protective coatings. Multi-layer coating systems are applied, typically comprising a zinc-rich primer, an epoxy intermediate coat, and a polyurethane topcoat (total DFT of 250-400 microns) for general corrosion protection. For highly corrosive environments, specialized epoxy-phenolic or ceramic-reinforced coatings are utilized, complying with ISO 12944 categories C4 to C5M.
6. Assembly & Integration: Mechanical, hydraulic (if applicable), and electrical sub-assemblies are integrated in a dust-free environment. Precision-machined pins, bushings, and high-performance bearings (e.g., self-lubricating bronze alloys or anti-friction roller bearings) are installed. The automated latching/unlatching mechanisms are calibrated, and all sensors (proximity, load cells, encoders) are wired and tested for functionality.
7. Rigorous Testing & Quality Assurance:
   • Dimensional Inspection: Full verification of all critical dimensions using calibrated instruments.
   • Load Testing: Static load tests at 125% of rated capacity and dynamic load tests at 110% of rated capacity for functional verification and structural integrity.
