Six successful factors of bottle cap mold
Nov 18,2022
Balanced flow and filling of materials. The flow balance of the plastic melt from entering the hot runner to the mold cavity has an important impact on the consistency and dimensional accuracy of the bottle cap product, which is especially important in the future production of lightweight and complex structure bottle caps.
The performance of fast color change Many injection molding companies will encounter the problem of long downtime during the color change process. For more color changes of bottle caps in the future, reducing downtime and saving material costs for color changes requires more detailed consideration in the design and manufacture of hot runners.
Multi-color, multi-material injection molding performance If a product needs to present multiple colors or materials (such as soft and hard plastics), molding on the same injection molding machine can greatly reduce processing procedures and labor costs, and improve production efficiency. But this also means that the hot runner system is relatively complex, and once a failure occurs, it will have a great impact on product quality and production schedule. Therefore, the repeatability and stability of the hot runner system are very important when multi-color and multi-material injection molding.
Gate quality Nowadays, brand companies have increasingly higher standards for the appearance of bottle caps, especially for daily chemical bottle caps. The appearance and size of the gate directly affect product quality. The valve needle hot runner gate closes the gate through the mechanical action of the valve needle. Compared with the heat-sealed gate, it is not affected by the cooling conditions at the gate and does not produce gate traces. Therefore, it is a daily chemical bottle with strict requirements. Ideal for covers.
Shortening the molding cycle and improving production efficiency Shortening the molding cycle of bottle caps has always been an important means for injection molding companies to pursue efficiency, reduce costs and improve product cost performance. A hot runner system with excellent performance and good thermal balance can help injection molding companies further shorten the molding cycle. In addition, the application of special hot runner systems such as high-cavity molds, stack molds, and rotary molds can double the production efficiency
Considering the total cost of ownership More and more injection molding companies have begun to use the concept of total cost of ownership to evaluate costs and make decisions. Different from simply considering the purchase cost in the past, the total cost of ownership not only includes the purchase cost of machines and molds, but also considers the installation, maintenance, service, energy consumption and other costs associated in later operations. For bottle cap products with high output and long life cycle, in addition to the investment in molds and machines in the early stage, high maintenance and operating costs may be incurred in the later stage. Using the total cost of ownership accounting method can allow bottle cap manufacturers to make purchasing decisions Make better choices in real-time and improve overall ROI.
