What is Sheet stamping / chemical etching of flow fields?

Sheet stamping / chemical etching of flow fields capability for titanium components

Metal forming capability for Sheet stamping / chemical etching of flow fields, with CNC press brake, die design, and springback compensation for titanium alloys.

Engineering Parameters & Capabilities

Press brake forming of titanium sheet uses CNC-controlled backgauges and variable-radius tooling to produce precision bends. Titanium's high springback (10–20° for Grade 5) requires over-bend compensation calculated from the specific alloy's elastic modulus, specifically for pins. Precision pins for chemical processing present unique challenges: cylindrical OD tolerance ±0.005 mm with chamfer/radius control. Tight straightness (< 0.02 mm over 50 mm) is required for press-fit applications.

Parameter Specification
Method CNC press brake with air bending / bottoming
Springback (Gr5) 10–20° depending on R/T ratio
Min Bend R 2×T (Grade 2) / 3×T (Grade 5)
