Sangu followed the philosophy of ISO management to carry out strict and constant quality control for all incoming raw materials, empty components, semi-finished products, and finished products. Advanced production and test equipment to make our products have zero error in quality, so our products can withstand scrutiny and the test of various certifications.

Measures to ensure the quality of our products:

 For the Raw Materials, the Incoming inspector would strictly check and control the material’s cleanliness, ensure no impurity defects occur during the production process.

 

 For the Injecting Process, the injection workshop's inspector will check the bottles as they come out from the injecting machine. We will remove any packaging that has bubbles, black dots, leakage,or scratches.

 

 For the Production Craft process, such as spray painting, hot-stamping, silk screen printing, etc. are all made by skilled workmates, and then the inspector will check each procedure to ensure no any imperfections on the packagings.

 

 When at the Assembling process, the assembly workshop’s inspector would have random inspections during assembly and before packaging the goods into cartons.

 

 When goods are ready for Shipment, we will carefully check the complete batch of packaging after it's assembled and random check when they are packed into the cartons for shipping. Ultimately ensure that the products received by customers are satisfactory.
