About quality management: Quantity Control
Quality Control is of immense importance and contributes directly to a manufacturer’s reputation and development. Therefore, we’re making consistently efforts on enhancing our quality control management throughout whole production processes from raw materials purchasing to finished products inspection, to assure that all Glass-Fused-to-Steel Tanks delivered by Center Enamel meet the international quality requirements.
Inspection & Analysis of Incoming Raw Materials
Batch-by-batch sampling plan for retrieval, make sure the actual operation conforms to the standards as all incoming materials need to be inspected for quality.
Acid & Alkali Resistance Test
Use 10g of solid citric acidor solid sodium carbonate to diluted with 100mldistilledwater (10% citric acid / 10% sodium carbonate solution) to test the acid and alkali resistance of the enameled panel.
1500V Holiday Test
Center Enamel conducts 1500V holiday test on double sides of all produced sheets, to make sure all delivered sheets are in best quality condition with zero discontinuity.
Impact Test
Use the hydraulic machine (pressing up to 15MPa)to test the fusion performance of enameled panel, make sure to offer increased longevity, ability to withstand higher mechanical stress and provide a safe solution to challenging storage applications.
Coating Thickness Test
Use the coating thickness gauges to test the enameling coating thickness, make sure Center Enamel’s Glass-Fused-to-Steel Tanks enameling coating thickness is in the standard range.
Tank Color Consistency Test
To make sure different thickness sheets from different batches can have same color shade, not only color pigments but alsoe nameled sheets need to be tested separately by a colorimeter.
Fish Scale Test
Put one standard enameled panel into the oven and fire at 400 ℃ for one hour, if no fish scale problem happens then it means the whole batch fabrication quality result is satisfied.
