The dropper bottle is an important object for accurate dosage in the pharmaceutical and cosmetic industries. Yinmai Glass Products guarantees that the customer’s requirement for the dropper bottle is met. In this article, we describe the dropper bottles that we make, how they are manufactured and the strict quality control measures undertaken to provide the best.

Production Process

1. Material Selection 

In the process of making dropper bottles, the first and foremost process involves the selection of raw materials. Yinmai Glas Products leverages high quality glass which is chemically stable so the contents preserved. Additionally, the glass that we use is lead-free and meets international standards of safety.

2. Glass Forming 

Materials being sorted and selected, the next step is melting the glass and forming it into preforms at high temperatures. Advanced molding technology incorporates precise shaping, equal thickness which is imperative in the production process of the dropper bottles. The preforms are then made off gradually cooled in able to reduce stress fractures.

3. Annealing

On an additional note, when the bottles are formed, they are subjected to an annealing process for the glass to gain its strength. It is the re-heating of glass up to a certain temperature followed by regulated cooling. This is a critical process to relieve internal stresses and strengthen the bottles.

4. Surface Treatment

Surface treatment processes are performed on the bottles after annealing. This involves cleaning and polishing of the bottles to ensure that there are no impurities on the surface and as well the bottles have a fine finish. The beauty of the bottles is however enhanced by surface treatment as it facilitates the decoration of bottles afterwards.

5. Assembly of Droppers

The next step involves the assembly of droppers. This refers to the process of fixing rubber or plastic droppers onto the glass bottles. Yinmai Glass Products makes sure that there are no problems with droppers so they are fully operational, allowing for accurate dispensing and no leakage.

Quality Control

1. In-Process Inspections

However, Yinmai Glass Products performs in-process inspections during every stage of the production of the glass products. Looking at the production line, our expert technicians are able to see problems and correct them straight away. This helps to reduce the number of defects and helps in controlling the quality of the end product.

2. Testing of the End Product

Last but not least, the dropper bottles are subjected to a series of post assembly tests and evaluations. These tests include the soundness of the structure, leak tests, and the performance of the droppers. Some of the parameters of the dropper mechanism are measured using sophisticated testing machines which deploy the dropper mechanism.

3. Adherence to Required Standards

Yinmai Glass Products complies with international norms regarding quality, including ISO standards. To ensure compliance with the requirements of the regulatory bodies of the pharmaceutical and cosmetic, the quality control activities of our company are carried out in the prescribed order.
