Manufacturing Process
The client provides the product design. Fimex engineers how to cast it with in-house CAD/CAM using SolidWorks, PowerSHAPE, and PowerMill for pattern development and mold design. Wood, resin, or metal patterns fabricated to spec. Casting simulation with SolidCast to optimize geometry, predict shrinkage, and eliminate defects before production.
Complex cores manufactured using two systems: Hot Box and Cold Box (new Brazilian machine). Ceramic and silica sand cores ensure accurate internal channels and cavities, even for highly intricate geometries.
Two molding processes for brass and copper: Green Sand and Permanent Mold. Each method selected to optimize part quality, dimensional accuracy, and output for brass and copper alloys.
Induction furnaces for brass and copper alloys. With varied casting processes: Standard, Gravity, and Low-Pressure (Permanent Mold). Chemical analysis per heat ensures precise alloy composition. Controlled pouring temperature and speed for optimal casting integrity and traceability.
Controlled cooling rates to achieve target microstructure and mechanical properties. Sand separation and reclamation systems minimize waste and ensure sand quality for reuse in subsequent production cycles.
Grinding, shot blasting, and robotic polishing cells remove gates, risers, and surface imperfections. Parts inspected before advancing to machining.
Dedicated brass machining floor (NEW 2024-2026): CNC machining centers, lathes, and cobots (robotic arms). Purpose-built for brass and copper alloy families with the latest technology.
Dedicated assembly area for final part integration. Components are assembled, and valves undergo pressure and leak testing to ensure compliance with customer specifications.
Full dimensional, metallurgical, and NDT inspection per customer specifications. Destructive testing (Charpy impact, tension/tensile, cross-section cuts). Non-destructive: ultrasonic, liquid penetrant, magnetic particle, radiographic, hardness, chemical analysis, dimensional, visual, leak testing, and pressure testing. 3D scanning for reverse engineering and dimensional verification. Every brass and copper part is verified before shipment.
Independent Process
Fimex offers open-die and closed-die forging for brass alloys, producing parts ranging from 0.200 kg to 1.200 kg. This process delivers superior mechanical properties through controlled deformation of heated metal.
Forging produces parts with enhanced grain structure, higher strength, and better fatigue resistance compared to cast equivalents — ideal for components requiring maximum structural integrity.
