Introduction To Large Metal Parts Manufacturing Business

Mayin is a premier specialist in the custom manufacturing of large parts, delivering comprehensive, single-source solutions for demanding industries including energy equipment, heavy machinery, aerospace, and shipbuilding. Our integrated approach combines state-of-the-art forging, heat treatment, and precision machining to produce components of superior quality and reliability.

Our heavy forging services utilize large-scale hydraulic presses to plastically deform metal, significantly enhancing material density and refining its internal grain structure. This open-die process creates high-strength, durable blanks for critical components like large gears and shafts, achieving an optimal balance of strength and performance. Following forging, our precision heat treatment processes—including annealing, quenching, and tempering (Q&T)—are crucial. We expertly control these thermal cycles to fine-tune the material’s hardness, toughness, and fatigue resistance, ensuring component stability under the most extreme operational conditions.

Our machining capabilities feature complementary vertical and horizontal orientations. Vertical Turning Lathes (VTLs) excel at processing heavy, large-diameter parts such as flanges, while our horizontal lathes achieve exceptional high-precision turning and threading on long-shaft components, with dimensional control within ±0.01mm. For complex structural parts like large housings and machine bases, our milling and boring operations leverage advanced 5-axis CNC machines. This allows for multi-sided milling and deep-hole boring in a single setup, with positioning accuracy for hole systems reaching the IT7 tolerance grade.

By meticulously managing the entire process from raw material to finished product, Mayin ensures the consistency and reliability essential for the manufacturing of large parts. Our integrated solutions help clients streamline their supply chain, reduce costs, and improve overall efficiency.
