The dispenser bottle should mainly have the following advantages:
1. Production in Class D clean workshop, effectively ensuring the sterility of products;
2. Quantitative filling, single use, to ensure the accuracy of medication;
3. Production by injection molding process, and the product quality is stable;
4. The bottle cap is specially designed, and it can be pierced and sealed by pressing down firmly, which is convenient to use;
5. Automatic filling and packaging of the assembly line to save labor costs
The principle of dispenser bottle injection molding is to add powder or powdered plastic into the hopper of the injection machine. The plastic is heated and melted in the injection machine to keep it flowing. Then it is written into the closed mold under a certain pressure and cooled After shaping, the molten plastic solidifies and becomes the desired plastic part.
The advantages of dispenser bottle injection molding are that the molding cycle is relatively short, the production power is relatively high, and the automated production is simple to complete.
In the preparation before molding, the plastic needs to be preheated and boring to prevent defects in the appearance of the plastic part after molding or degradation, which affects the appearance and inner quality of the plastic part. When changing the material or changing the product, the barrel needs to be cleaned. The injection molding process of the drop bottle includes: feeding, plasticizing, film filling, pressure maintaining and shrinking, cooling after the gate is frozen, and demoulding. After the dispenser bottle injection molding technology is completed, the plastic parts are processed afterwards. Because of uneven plasticization or uneven crystallization, orientation, and heating and cooling of the plastic in the cavity, there will inevitably be some internal stress inside the plastic part, which will then cause the plastic part to deform or crack during use. Therefore, we should find a way eliminate.
