Manufacturing Process Highlights:

1. Design and Simulation: The process begins with advanced CAD (Computer-Aided Design) and FEA (Finite Element Analysis) to optimize structural integrity, minimize stress points, and ensure efficient material flow. This digital prototyping phase is crucial for perfecting the geometry of the double screws and the pressing chamber.
2. Material Selection: Critical components that come into contact with raw materials and oil are fabricated from food-grade Stainless Steel (AISI 304 or 316L). This choice ensures excellent corrosion resistance against various oil types and facilitates easy cleaning, meeting rigorous hygiene standards such as FDA compliance for food processing equipment. For the high-wear components like the pressing screws and cages, specialized high-strength alloy steels are selected for their exceptional wear resistance and durability, capable of withstanding continuous high-pressure operation.
3. Precision Casting and Forging: Major structural components, such as the main frame, gearbox housing, and parts of the pressing chamber, undergo high-precision casting or forging processes. Casting ensures complex geometries can be formed with inherent strength, while forging enhances material density and grain structure, resulting in superior mechanical properties and fatigue resistance crucial for a LZY-206 Double Screw Cold Oil Press.
4. Advanced CNC Machining: The core of the LZY-206's efficiency lies in the precision of its components, particularly the double screws and the pressing cage. These parts are meticulously machined using state-of-the-art CNC (Computer Numerical Control) equipment. CNC machining ensures exceptionally tight tolerances (e.g., ±0.01 mm for critical surfaces), smooth surface finishes, and perfect alignment, which are vital for maximizing oil yield, minimizing residual oil, and ensuring smooth, vibration-free operation. This precision directly contributes to the machine's extended service life and consistent performance.
5. Specialized Heat Treatment: The alloy steel screws and other wear-prone parts undergo a multi-stage heat treatment process, including quenching, tempering, and surface hardening. This process significantly increases their hardness, wear resistance, and toughness, extending their operational lifespan even under continuous heavy loads.
6. Welding and Assembly: Structural frames and ancillary components are expertly welded, ensuring robust connections and structural stability. The subsequent assembly process is carried out by skilled technicians who adhere to strict assembly protocols, including precise alignment of shafts, bearings, and gears to minimize friction and maximize mechanical efficiency.
7. Rigorous Quality Control and Testing: Each LZY-206 Double Screw Cold Oil Press unit undergoes a comprehensive series of tests before dispatch. This includes:
   • Material Inspection: Adherence to ASTM and EN standards for chemical composition and mechanical properties.
   • Dimensional Accuracy: Verification against engineering drawings using precision measurement tools.
