Production Process
-
Material Blanking: High-grade stainless steel coil is precision blanked into discs of specified diameter, ensuring material consistency and grain direction for optimal drawing.
-
Multi-Stage Deep Drawing: The blank undergoes progressive drawing through a series of precision dies, gradually forming the thin-walled sleeve/bushing shape with controlled wall thickness reduction and height.
-
Trimming & Sizing: The drawn cup is trimmed to exact length and may undergo a final sizing or ironing operation to achieve the precise inner diameter (ID), outer diameter (OD), and concentricity.
-
Heat Treatment (Annealing): Performed between drawing stages or as a final step to relieve internal stresses, restore material ductility, and prevent cracking.
-
Secondary Machining & Finishing: Includes deburring, machining of specific features (grooves, holes), and application of surface treatments like passivation for enhanced corrosion resistance.
-
Comprehensive Inspection & Packaging: 100% dimensional check with air gauges/CMM, surface defect inspection, and batch testing for material certification before protective packaging.
