What is the normal production flow for precision screwdriver sets?

The normal production flow for precision screwdriver sets is:

Material preparation: steel, aluminum, plastic, magnets, bearings, and packaging materials are prepared

Bit machining: screwdriver bits are cut, formed, ground, and machined to the required profiles

Heat treatment: S2 or CR-V bits are hardened and tempered to reach the required hardness and toughness

Surface treatment: black oxide, plating, coating, or other anti-corrosion finishes are applied

Bit inspection: dimensions, hardness, tip accuracy, straightness, runout, and screw fit are checked

Handle production: aluminum or plastic handles are CNC-machined, molded, anodized, coated, or assembled

Magnet and tail-cap assembly: magnetic holders, bearings, rotating caps, and internal parts are installed

Accessory preparation: extension shafts, tweezers, pry tools, adapters, and other accessories are inspected

Set assembly: bits and accessories are placed into the case or tray according to the approved configuration

Functional inspection: bit retention, handle rotation, fit, appearance, and accessory function are checked

Packaging: retail boxes, manuals, labels, barcodes, and outer cartons are completed

Final QC: quantity, appearance, dimensions, hardness, configuration, packaging, and AQL requirements are verified

Pre-shipment inspection: finished goods are compared with the approved golden sample and order specification before release

For electric precision screwdriver sets, additional production steps include motor, gearbox, PCB, battery, torque, speed, charging, runout, automatic-stop, and aging tests.

For ToolQeen OEM projects, the production flow is controlled against the approved sample, drawing, BOM, bit specification, hardness requirement, packaging artwork, and QC standard from incoming materials through final shipment.
