Spraying method of wine bottle

The spraying production line for glass bottles is an essential process in enhancing the aesthetic and functional qualities of wine packaging. This line typically consists of several components: a spray room, a suspension chain, and an oven. Ensuring quality in the spraying process involves careful attention to various factors, including water treatment and the surface cleanliness of the glass bottles. Below are the recommended steps for an effective spraying process:

1. Initial Processing

• Pretreatment Setup: The pretreatment phase includes adjustments to the main stripping table. In colder regions, it’s crucial to maintain the temperature in this section to ensure effective processing. Insulation may be necessary to avoid suboptimal treatment results.

2. Pre-heating Period

• Duration: This phase typically lasts 8 to 10 minutes. The purpose is to allow the glass bottle to acquire some waste heat before entering the powder chamber. This heat enhances the adhesion of the powder coating.

3. Purification Section

• Dust Removal: If the spraying workpiece has stringent quality requirements, a purification step is vital. This process involves blowing away dust and particles from the workpiece to prevent contamination during spraying. A clean surface is crucial for achieving high-quality results.

4. Powder Spraying Stage

• Technical Expertise: The quality of the spraying largely depends on the technique used by the operator. Skilled operators are essential for achieving a uniform and high-quality powder coating. Glass bottles remain a prominent choice in beverage packaging due to their unique qualities that other materials cannot replicate.

5. Drying Stage

• Temperature and Time Control: The drying phase requires careful monitoring of both temperature and duration. Optimal temperatures typically range from 180 to 200 degrees Celsius, depending on the material of the workpiece. It is important to minimize the distance between the drying furnace and the powder chamber, ideally within 6 meters, to ensure efficient drying.

Conclusion

Implementing these steps effectively will ensure high-quality spraying of wine bottles, maintaining their aesthetic appeal and functional integrity. Attention to detail in each phase of the process, from pretreatment to drying, is essential for achieving the best results in glass bottle finishing.
