The difference between one-step injection and two-step molding and their respective characteristics:
One-step method and two-step method, from raw materials to finished products are completed in a device. The production process is simple, once formed, its controllability is strong, the precision of the bottle mouth is high, and no secondary heating is needed, so the energy consumption is low.
The two-step process requires injection molding of the preform, followed by secondary processing on the blow-molding machine and blow molding. It is completed by the injection molding machine and the blowing machine twice. It can be connected to the production line or it can be divided into production lines.
One-step method and two-step method are suitable for what kind of application:
The one-step process is more suitable for products with medium and small batch sizes and high hygiene requirements. Of course, it is more advantageous for asymmetrical bottles and thick-walled bottles.
The current two-step method is high-speed equipment, which is suitable for mass production of water bottles, beverages and the like. One is low speed (or semi-automatic) for some small quantities of products. The following figure shows a bottle type that can be processed in one step:
One-step equipment features:
One-step processing equipment has three-station equipment, such as Aoki solid equipment. Three of these stations are: preform injection molding and conditioning temperature - stretch blow molding - product removal. In addition to three-station equipment, there are four-station equipment, such as Nova's equipment, which adds a cooling station to the original three stations, while the ASB equipment is based on a three-station heating station.
