DESCRIPTION 

Our state-of-the-art Automatic Double Station Double Head Extrusion Blow Molding Machines, crafted by Dawson, are the ultimate solution for crafting high-quality hanging bottles made from PP (polypropylene). Engineered with precision and innovation, these machines offer a seamless production process, exceptional customization capabilities, and top-notch safety features. Let's take a deeper dive into the core features that set our machines apart.

The extrusion blow molding process employed by our machines is a meticulously choreographed sequence, combining cutting-edge technology and engineering prowess to produce flawless hanging bottles. It all begins with the plastic resin, typically in the form of small pellets, being fed into the machine's hopper. From there, the resin embarks on a transformative journey within the extruder.

Inside the extruder, a specialized screw rotates at a precisely controlled speed. As it turns, the screw not only propels the resin forward but also subjects it to intense mechanical shearing and heat. This combination gradually melts the solid pellets, converting them into a molten, viscous mass. The temperature and pressure within the extruder are carefully monitored and adjusted to ensure the resin reaches the optimal molten state for processing.

Once the plastic resin is fully melted, it is extruded through a precisely engineered die. This die gives shape to the resin, forming a continuous, hollow tube known as the parison. The dimensions of the parison, including its diameter, length, and wall thickness, can be finely tuned. For example, by adjusting the rotational speed of the extruder screw, modifying the temperature profile along the extruder barrel, or altering the geometry of the die, we can create parisons tailored to the specific requirements of different hanging bottle designs.

The freshly formed parison is then rapidly transferred to the mold. This transfer is a critical step, and our machines are equipped with high-speed, precision mechanisms to ensure the parison is accurately positioned within the mold cavity. Once in place, the mold closes around the parison, sealing it at both ends. Compressed air is then forcefully introduced into the parison through a dedicated air inlet. The pressure of the air causes the molten plastic to expand, conforming precisely to the contours of the mold cavity. This inflation process is carefully regulated to achieve uniform wall thickness and consistent product quality.

After the plastic has fully expanded and taken on the shape of the mold, the cooling phase commences. Our advanced cooling systems utilize a combination of water-cooled channels integrated into the mold and external air-blowing mechanisms. This dual cooling approach rapidly dissipates the heat from the plastic, causing it to solidify and acquire the necessary strength and rigidity. Once the cooling process is complete, the mold opens, and the finished hanging bottle is gently ejected using a pneumatic ejection system, ready for further inspection, packaging, and distribution.

The "double station" feature of our Automatic Double Station Double Head Extrusion Blow Molding Machines is a game-changer in the world of manufacturing. It consists of two separate, fully functional workstations, each capable of performing the entire blow molding process independently. This design offers a multitude of benefits that significantly enhance production efficiency.

One of the key advantages of the double station setup is parallel processing. While one workstation is in the midst of blowing a parison into a bottle, the other workstation can be simultaneously preparing for the next cycle. This means that as soon as one bottle is ejected from the mold, the other workstation is already primed and ready to start the process anew. This seamless transition between stations eliminates downtime and maximizes the utilization of the machine, resulting in a substantial increase in overall production output.

To illustrate the impact of the double station feature, consider a typical production scenario. In a single station machine, the entire process—from parison formation to bottle ejection—must be completed before the next cycle can begin. This often leads to idle periods where the machine is waiting for the previous cycle to finish. In contrast, our double station machines can continuously alternate between the two workstations, ensuring a steady flow of production. For example, if a single station machine can produce 100 bottles per hour, our double station machine can potentially double that output, reaching 200 bottles per hour under optimal conditions.

Moreover, the double station design provides flexibility in production. It allows for the production of different bottle designs or sizes simultaneously, depending on the specific requirements of the customer. This versatility is invaluable for manufacturers who need to cater to a diverse range of product lines, enabling them to quickly switch between different production runs without significant downtime.

Complementing the double station feature, our machines' "double head" configuration takes production efficiency to the next level. The double head refers to the presence of two extrusion heads or nozzles, each responsible for forming a parison. These extrusion heads work in tandem, extruding molten plastic simultaneously to create two parisons at once.

The dual extrusion heads are engineered with precision to ensure consistent and accurate parison formation. Each head is equipped with its own independent control system, allowing for precise adjustment of parameters such as extrusion speed, temperature, and parison thickness. This level of control ensures that the parisons produced by both heads are identical in quality and dimensions, guaranteeing uniform bottle production.

The double head feature significantly reduces the overall cycle time of the blow molding process. Since two parisons are produced simultaneously, the time required to produce a batch of bottles is cut in half compared to a single head machine. This not only increases the production speed but also improves the machine's throughput, enabling manufacturers to meet high-volume production demands with ease.

In addition to enhancing production speed, the double head configuration also offers cost savings. By producing two parisons at once, the machine can utilize the same amount of energy and resources more efficiently, reducing per-unit production costs. This makes our double head machines an economically viable option for manufacturers looking to optimize their production processes and increase profitability.
