Quality Control

Adhering to the value of win-win with our customers, we never compromise on high quality standards. We recognize that every step of the manufacturing process, from receipt of raw materials to melting, forming, inspection, and packaging, affects the quality of the final product. To this end, we have adopted a series of glass bottle quality control measures, from raw material inspection to production process control to post-production inspection to ensure that the products are qualified.

Raw material inspection before production:

In order to be able to control the quality of incoming raw materials, we have established technical specifications for each raw material used to produce glass bottles. Before production, we will conduct inspections of raw materials, including composition inspection, purity testing, and physical performance testing to ensure that the raw materials quality meets the requirements.

Quality control in production:

We focus on quality control during the production process and ensure the quality of each process through strict operating procedures and technical requirements. For specific manufacturing processes, please refer to glass bottle manufacturing

1. Bottle size, capacity, weight inspection

We will inspect the size, capacity, and weight of each glass bottle to ensure that it conforms to customer drawings or is consistent with the physical sample.

2. Glass bottle defect inspection

Is there any rotten silk, shriveled silk, fried mouth, or fried lines on the mouth of the bottle?

Is the bottle crooked? Is it crooked?

Is the verticality and inclination of the bottle consistent with the drawing or the actual object?

Are there any gaps at the bottom of the bottle, rust on the mesh bag, and whether the bulkhead coil at the bottom is straight?

Is the surface of the bottle clean and free of stains, how smooth is it, and whether there are any scratches

Whether the surface of the bottle is even and whether there are stones or lumps

Are there bubbles on the surface of the bottle?

Is there any foreign matter or corrosive liquid left in the bottle?

Is the pattern on the bottle surface clear?

3. Cover accessories inspection

Is the cover clean and the appearance consistent with the customer’s requirements?

Does the bottle cap match the bottle mouth? Is there putty on the mold at the anti-counterfeiting part of the bottle cap?

Bottle cap sealing test, lining seal placement

Put each cap on and see if it slips or doesn’t fit properly and how the torque works

4. Logo check

Check whether the logo on the bottle is affixed and whether the size, color, and position are correct.

The logo must not be blurry, bubbled, ghosted, missing, dirty, etc.

5. Packaging inspection

Carefully check the packaging method of the product, the labels and contents used, the contents of the attached instructions, whether the marks inside and outside the box are correct, and whether the packaging is intact.

6. Palletizing, loading, and delivery inspection

We will inspect the packaged glass bottles before palletizing, loading, and shipping to ensure the integrity of the pallet guard and the stability of the pallet to ensure the safety of the product during transportation.
