Quality

Raw Material Inspection:
We control the quality of raw materials, they are tested the ingredients before they leave the factory.
Mechanical properties like hardness and tensile strength are verified.
In-process Inspection:
During extrusion, dimensions of the trim profiles are continuously monitored using laser measuring systems.
Surface finish is checked visually and with profilometers to ensure smoothness and absence of defects.
Final Testing:
Coated trims undergo adhesion tests where the coating is scored and subjected to tape pull tests.
Salt spray tests are conducted to assess corrosion resistance.
Process Control:
SPC charts monitor extrusion temperatures and speeds to ensure consistency.
Regular calibration of measuring equipment and maintenance of machines.
Corrective and Preventive Actions:
If a batch shows dimensional deviations, root cause analysis might reveal an extrusion die issue, leading to its replacement and recalibration.
Preventive actions include scheduled maintenance and staff training on new QC techniques.
Documentation and Record-Keeping:
Detailed logs of material inspections, in-process checks, and final tests are maintained.
Records of any corrective actions taken and process adjustments made.
Conclusion
Quality control in tile trim manufacturing is a comprehensive process that ensures the product meets the highest standards of quality and durability. By adhering to rigorous inspection, testing, and continuous improvement practices, manufacturers can produce tile trim that not only meets customer expectations but also performs reliably in various applications, which helps us maintain a strong market reputation and compliance with industry standards.
