Dlaczego audyty fabryczne są ważne w produkcji elektrycznej
For businesses sourcing switches, sockets, and other electrical products from overseas — particularly from a producent gniazd przełączników Chiny based — a pre-order factory audit is one of the most important steps you can take to protect your investment. A factory audit provides independent verification of the supplier’s capabilities, quality systems, and reliability. This guide outlines the key areas to assess during an electrical product factory audit.
Cztery filary audytu fabrycznego
1. Zarządzanie i dokumentacja
Begin by reviewing the factory’s management systems and documentation:
- ISO 9001 certificate — verify validity and scope (should cover switch and socket production specifically)
- Organisation chart — understand the management structure and quality reporting lines
- Quality manual — documented procedures for QC, corrective actions, and continuous improvement
- Operator training records — evidence that production staff are trained on quality standards
- Batch traceability system — can the factory trace a finished product back to its raw material batch?
2. Zdolność produkcyjna
Assess the factory’s physical production capacity:
- Injection moulding: Number and type of moulding machines. Newer electric moulding machines produce more consistent parts than older hydraulic ones.
- Tooling workshop: Does the factory maintain and repair its own moulds, or rely on external suppliers?
- Linie montażowe: Observe the line speed, worker training, and quality checks at each station
- Miesięczna produkcja: Can the factory consistently meet your required volumes? Check for other large clients that might compete for capacity
- Future-proofing: Does the factory invest in new equipment and automation? Visit the MORDIO factory for an example of a well-equipped manufacturing facility.
3. Laboratorium kontroli jakości
Poważny producent będzie posiadał własne laboratorium QC do testowania. Sprawdź następujący sprzęt i procedury:
- Dimensional measurement: Callipers, micrometres, profile projectors for checking product dimensions against specifications
- Electrical testing: Hi-pot (dielectric strength) testers, insulation resistance testers, continuity testers
- Mechanical testing: Switch endurance test rigs (20,000+ cycles), plug insertion/withdrawal force testers
- Environmental testing: Temperature/humidity chambers for material aging tests
- Flame retardancy testing: Glow wire test apparatus for verifying PC/ABS material compliance
MORDIO maintains an in-house testing laboratory as part of our quality assurance programme.
4. Kontrola surowców
Jakość gotowych produktów w dużej mierze zależy od surowców. Sprawdź:
- Material supplier qualification: Does the factory audit its raw material suppliers?
- Incoming material inspection: Are incoming batches of PC pellets, copper strip, and silver contacts tested before use?
- Material storage: Are materials stored correctly (temperature-controlled for some plastics, dry storage for copper)?
- Material certificates: Does the factory maintain certificates of analysis from material suppliers?
