Mineral water bottle preform mold classification is mainly based on its structure, function and production requirements. The following are detailed answers to the classification of Mineral water bottle preform mold:
1. Classification by molding method
Injection mold: This is the most common type of mold used in the production of mineral water bottle preforms. The processing equipment corresponding to the injection mold is an injection molding machine. After the plastic is heated and melted in the injection molding machine, it enters the mold cavity through the mold's pouring system, and is cooled and hardened to obtain the product. Injection molds usually have multiple components such as molding parts, pouring systems, guide parts, and ejection mechanisms.
Blow mold: Blow mold is used to form hollow plastic container products, such as mineral water bottles. There are many forms of blow molding, such as extrusion blow molding, injection blow molding, etc. The structure of the blow mold is relatively simple and the cost is low.
2. Classification by cavity number
Single-cavity mold: A single-cavity mold can only produce one bottle, so the production efficiency is low, but the manufacturing cost is relatively low, and it is suitable for small-scale or customized production needs.
Multi-cavity mold: Multi-cavity molds can manufacture multiple bottles at the same time, significantly improving production efficiency and reducing production costs per unit product. Common multi-cavity molds such as 1 out of 64, etc., can produce 64 bottle preforms at a time.
3. Classification according to technical characteristics
Hot runner mold: Hot runner mold is suitable for producing bottles with extremely high quality requirements, and can achieve the effect of no misalignment, no ligaments, and no shrinkage holes. However, the manufacturing cost of hot runner molds is high and requires high technical level and production technology.
4. Other categories
In addition, there are molds customized according to bottle characteristics such as bottle height, diameter, inner diameter of the neck, angle and thickness. These molds can meet the needs of specific bottle types or specific customers.
To sum up, there are various classifications of Mineral water bottle preform molds. Molds under different classifications have their own characteristics and scope of application. Manufacturers can choose the appropriate mold type according to actual production needs.
