With the development of Blowliner, which is a single-stage injection stretch blow molding machine, Bruckner Group Kiefel's daughter company, Mold & Matic, opened up a new market. The company is presenting the product to NPE in Orlando.
Bernard Hornhuber, sales manager for blow molding technology, developed Blowliner: 'The customer appreciates the fact that the complete space saving from a single source, that is, from granulation to packaging is achieved.'
The Blowliner is available in three sizes. The line can handle PET, PP, HDPE, and with its intelligent concept, it can be upgraded to multi-layer applications at any time. Bernard explained: 'Our customers need to be on the same machine Flexible production of different containers with capacities from 10 ml to 5 litres, and Blowliner fulfills all these wishes, which helps our customers to continuously increase the utilization of the plant.
The injection unit is a vertical hydraulic Engel machine located at the starting point of a linear machine. Preforms are created here; this depends on the product range from 8 to 64. They are removable by a linear robot with a clamping mandrel and The preforms are transferred to a stretch blow moulding unit. The machine uses one to four rows of blow moulding tools and accepts preforms with a diameter of 10 to 150 mm. Each series of cavities has its own pre-blowing valve and main Blow valve, so it is possible to set the pre-blow and main-blow pressure independently. The entire stretch blow-molding unit is equipped with a servo-motor drive to provide precise repeatability, precision and energy efficiency. At the end of the blow molding process, the integration The vacuum chuck of the linear discharge system removes the finished product from the tool and places it precisely on the conveyor belt or directly in the box.
In Blowliner's concept, considering the integration of many tool technologies. Bernard recalled: 'Our goal is to increase the number of chambers, thereby increasing productivity, while increasing the optimization cycle time for existing equipment. It should be possible to use tools. Hot end to create very different products, size and number of chambers. The solution is a balanced hot aisle tool with a pin locking system. This provides capacity for different product sizes and tool configurations. The Blowliner M allows a cycle time of 10 seconds. The management time of the Blowliner S can be less than 8 seconds. At the NPE, visitors will have the opportunity to experience the life of the Blowliner M at the W2727 booth.
