Optical Sorting & Packaging · Bekasi plant Process overview
100% optical sorting and application-specific packing
At M1.0 a defective screw is almost invisible. A bent shank, a short length or a missing thread may pass a visual check but will jam a feeder or cross-thread a housing. The cost of that failure is not the screw — it is the stopped line, the rework and the containment report.
Every production lot passes through optical sorting that combines vision for head geometry, drive presence and surface defects with laser measurement for length and diameter. Parts outside the window are ejected, and the accepted stream is packed according to the customer’s feeding method: taped reel, matrix tray, bulk bag or cleanroom bag.
Step by step
How the process runs
Each step has a defined control point. The sequence is not arbitrary — changing it changes the result.
De-burring and cleaning
Parts are tumbled and degreased so that debris does not create false rejects during inspection.
Vision inspection
Cameras check head diameter, head height, drive presence, concentricity and surface defects at up to 2,000 pcs/min.
Laser dimensional check
Laser gauges measure length and shank diameter, rejecting parts outside the drawing window.
Ejection and verification
Rejected parts are ejected into a locked bin, counted and reconciled against the input quantity.
Packing
Accepted parts are packed on taped reel, in matrix trays, or in bulk and cleanroom bags according to the assembly method.
Label and traceability
Each package carries lot code, quantity, size, finish and inspection status, linked to the production record.

| Reel taping | 8 – 44 mm tape width, EIA-481 compatible |
| Matrix tray | Anti-static, custom cavity |
| Cleanroom bag sealer | Class 100,000 packing area |
| Counting and weighing | 0.001 g resolution, piece-count verification |
| Label system | Lot code, QR, customer part number |
Process control
What is checked, and when
A control that is not recorded is not a control. Each item below generates a record linked to the lot code, retained for the programme duration.
01
Sorter calibration and master sample verification at start of shift
02
Reject bin reconciliation per lot
03
Piece-count verification by weight and sampling
04
Label accuracy check before carton sealing
05
Cleanroom particle monitoring where applicable
06
Packaging integrity and desiccant check
07
Retained sample per lot
08
Traceability from lot code to production record
