Quality Control in Manufacturing Processes

Idle condition never touch anything is considered an intentional change.

Personnel transfers without training must be confirmed as an intentional change.

Foil lot change is listed under Nissha Japan (Kameoka) as an intentional change.

Mold polishing is categorized under incidental change.

Replacement of the cavity inserts is considered an intentional change.

Mold breakdown is classified as an incidental change.

Visual inspection/Product dimensions are associated with both personnel transfers and measuring equipment updates.

A process change is required when the measuring equipment is repaired.

Visual inspection is used in the production sampling inspection process.

CNC production sampling inspection does not involve boss pin height measurements.

Overall measurement is part of the production sampling inspection process.

Boss pin height is never considered in visual inspection.

The validation of process window suitability does not use visual inspection.

The production sampling inspection includes both the measurement of control points and the boss pin height.

Overall measurement is conducted only once during the production sampling inspection.

Replacement areas are not included in the inspection procedures.

Incidental and Intentional Change List

A list tracks changes, categorized as incidental or intentional.
Confirmation and communication are required for these changes.

Quality Control Procedures

Checks include quantity, overall measurements, and replacement part measurements for impacted areas.
Visual inspections cover various defects: white marks, dryness, uneven coloration, black/white lines, fading, bleeding, color tone, anti-glare issues, moire, cloudy areas, polarized visibility, ink flow, air bubbles, weld lines, foil cracks, sink wrinkles, and sink marks.
Process changes involve resin lot, material, foil lot, and mold changes.

Mold Maintenance and Repair

Mold touch is not permitted in idle conditions.
Routine maintenance includes normal service, spare part replacement, and mold polishing/correction.
Cavity (CAV) insert replacement and mold grain insert procedures are detailed.
Mold breakdowns require repair.

Process Adjustments

Process adjustments can be within or outside the process window.
Process window range reviews are necessary.
Process changes and design changes affect foil procedures.

Personnel Changes

Personnel transfers without training are noted.
Personnel transfers with training are also documented.

Measuring Equipment

Measuring equipment maintenance and repairs are listed.
Equipment updates are included.
Production sampling inspections and overall measurements are conducted.
Control points and boss pin heights are measured during sampling.
Inspections might focus on dimensions of replacement parts.

Validation

Validation of process window suitability is a required step.

General Notes

Parts should be replaced, not repaired.
Construction/repair without permission from the Kameoka Factory is prohibited.
Contact the factory manager or Kameoka Factory for cases outside the documented list.

This quiz covers essential aspects of quality control, including the distinction between incidental and intentional changes, visual inspections for defects, and maintaining and repairing molds. Understanding these procedures is crucial for ensuring product quality and process efficiency.
