Slotted Pins Manufacturing Process Flow

Tooling & Die Manufacturing

Progressive dies control slot geometry, forming radius, and compression behavior during insertion.

Raw Material Slitting

Spring steel strips are slit into controlled widths to maintain stable feeding and forming accuracy.

Stamping Process

Steel strips are stamped and rolled into elastic cylindrical structures with controlled slot width.

Heat Treatment

Quenching and tempering stabilize hardness, elasticity, and deformation resistance under cyclic load.

Heat Treatment Inspection

Hardness, deformation, and dimensional stability are checked after thermal processing operations.

Grinding Process

Grinding controls outer diameter tolerance and improves surface consistency before coating.

Surface Treatment

Natural Finish + Protective Lubricant
Electroplating, Phosphating, Coatings (Hydrogen Embrittlement Relief)

Optical Sorting

Optical systems detect slot deviation, deformation, and surface defects before packaging.

Quality Inspection System

A strict quality inspection system is implemented throughout the entire slotted pin manufacturing process to ensure stable dimensional accuracy, reliable fastening performance, and consistent batch quality for industrial applications.

Multi-Stage Inspection Management

Our inspection procedures cover raw materials, production dimensions, slot consistency, hardness performance, surface quality, and final product verification before shipment.

Raw materials: elemental properties

Molding: appearance, dimensions

Heat treatment: hardness

Surface treatment: corrosion detection

Finished product dimensions & shear force
