Ⅰ. Overall Quality Control Objectives
1. Achieve 100% qualification rate of finished machines before delivery and prevent equipment with major hidden quality risks from leaving the factory.
2. Ensure stable equipment operation accurate laser parameters and standardized safety protection performance.
4. Meet customer technical requirements and industry standards to realize one-time acceptance at the customer site.
5. Establish a full traceability system to quickly locate and close after sales quality problems.
Ⅱ. Full-process quality control in manufacturing and production
1. Check the model power wavelength and qualification certificate of core components such as laser generator optical fiber scanning galvanometer power module PLC control system and cooling system Inspect the dimensional and appearance quality of structural parts such as frame gun body and sheet metal Verify the insulation and protection level of electrical accessories such as cables switches and protective lenses Establish batch accounts for all materials and prohibit unqualified materials from warehousing and production.
2. In-process Quality Control (IPQC)
In structural assembly control the verticality and levelness of frame assembly ensure no extrusion or bending of optical fiber wiring and conduct pressure maintaining leakage prevention test for cooling water circuit In electrical construction separate strong and weak current wiring with firm connection and reliable grounding fully test the emergency stop and laser interlock protection circuit Ensure accurate laser collimation and focusing in optical path assembly no scratches or stains on protective lenses and no stress damage in optical fiber installation.
3. Final assembly semi-finished product debugging quality control
Debug and calibrate core parameters such as laser power pulse energy and scanning angle Detect the temperature control stability of the cooling system to avoid over temperature alarm Test touch screen operation mode switching and fault alarm functions Conduct full angle operation test of galvanometer and perform continuous power on aging of the whole machine for more than 8 hours without crash error report and abnormal temperature rise.
4. Final product inspection for shipment (FQC)
Review the overall laser parameters cleaning accuracy and working efficiency of the machine strictly inspect safety protection functions such as emergency stop key switch and laser warning Check the equipment appearance paint and shell without bumps and scratches with clear nameplate marks Count supporting accessories tools manuals and qualification certificates The machine can only be delivered after passing inspection and issuing a test report.
Ⅲ. Packing and shipping quality control
The equipment adopts professional moisture proof and shock proof packaging and precision parts such as laser gun and protective lenses are reinforced and protected separately Recheck the order model power configuration and quantity before delivery to ensure consistent goods and order information Select formal logistics remind light handling moisture proof and bump proof transportation and track the logistics status throughout the process.
Ⅳ. On-site Installation and Delivery Quality Control for Clients
Unpack and inspect goods with customers to confirm no transportation damage to equipment and accessories Standardize on site positioning wiring water circuit connection and grounding installation Test laser output parameters and rust paint removal cleaning effect on site and retest safety alarm and emergency stop functions Provide training on equipment operation daily maintenance and simple troubleshooting for operators Complete signature and closed loop delivery after acceptance without errors.
Ⅴ. Post-sales Quality Traceability and Closed-loop Management
Establish a full life cycle quality file of equipment and keep all records of production inspection debugging delivery and on site acceptance Respond quickly to customer quality problems within 24 hours accurately locate fault causes and make rectification Conduct regular quality reviews optimize production assembly inspection test and delivery processes and continuously improve the overall stability and quality of equipment.
