Why Choose Machined Stainless Flange Plates Instead of Cast Parts?
Compared with investment casting or sand casting solutions, fully machined stainless flange plates offer significant advantages for critical sealing and pressure applications:
Zero Casting Defects
Machined directly from solid material eliminates internal porosity, shrinkage defects, and sand contamination, ensuring excellent structural integrity.
Superior Material Consistency
Solid stainless steel bar and forged blanks provide a uniform grain structure, improving fatigue resistance during repeated pressure cycles and temperature changes.
High Precision Sealing Performance
Advanced CNC machining ensures sealing face flatness up to ±0.01 mm, supporting reliable connections in high-pressure, vacuum, and high-purity systems.
Excellent Dimensional Repeatability
CNC-controlled production provides consistent bolt hole positioning, thread accuracy, and overall dimensions from prototype quantities to mass production.
