Husky introduced a one-step, low-yield bottle production process, IndexSB Machinery, which is aimed at producing a variety of low-yield, but often-conversion die bottle container manufacturers on a single machine. The machine uses the Husky Index pin model. Two cores reduce the cycle time and increase overall system productivity. The two cores are mounted on a rotary index and provide extended core cooling time. In this way, IndexSB's cycle time is 25%-40% faster than other one-step machines of the same type. The mold uses Husky's valve gate hot runner technology to provide consistent fill, improve gate quality, and minimize AA production.
IndexSB is highly flexible and can produce containers from 25 ml to 5 liters, with a bottleneck diameter up to 110 mm. To achieve this flexibility, the machine features a quick-change feature that allows the full set of tools to complete the replacement process within two hours. If you just change the blow mold, 15 minutes will be enough to complete the mold change process. The machine is also air-conditioned with an air conditioning station equipped with an infrared oven to optimize the temperature distribution of the preforms prior to blowing.
The one-step process line first moves the preform 60° to the first air conditioning station. Using an infrared oven, heat is precisely controlled and the preform temperature distribution is optimized. The preforms are constantly rotating in the air conditioning station. The preform is then subjected to a draw-blown process to achieve the final shape. The blowing process improves the mechanical properties of the material and makes the container better quality.
The bottles produced by IndexSB include cosmetics, health and personal care products, and food and beverage containers.
