As a reliable manufacturer, in order to ensure that the goods delivered to the company are in standardized high-quality packaging, the first batch of qualified products produced by each machine needs to be tested before mass production.

Our quality inspectors pour liquids into bottles of all sizes. During the test, ensure that the bottle mouth must be dry. Put the container on dry paper, so that after passing through the machine, you can judge by the paper whether it has leaked.

Put the tray with the container in the vacuum compressor, and check whether the product packaging is qualified through the machine-made air pressure difference. After the quality inspector takes out the product to check and confirms that the paper on the tray is dry, this batch of products will pass this test and be put into production.
