• Surface Roughness Analysis: Verification of surface finish specifications critical for sealing performance

• Optical Comparators: Rapid 2D feature verification without contact

• Custom Fixturing: Simulation of assembly conditions for functional validation

• Pressure Testing: Verification of pressure integrity under simulated operating conditions

Specialized fluid component manufacturers employ comprehensive inspection methodologies to verify all critical dimensions and features. This commitment to measurement precision ensures that components will perform as intended in fluid systems .

Statistical Process Control for Manufacturing Consistency

Implementing statistical process control (SPC) methodologies throughout the manufacturing process ensures consistent quality across all fluid components:

• First-Article Inspection: Comprehensive verification of all dimensions on initial parts

• In-Process Controls: Regular measurement of critical dimensions at predetermined intervals
