DSB70-II Extrusion Blow Molding Machine: Your Trusted Partner for High-Quality Wide-Mouth HDPE Containers

The DSB70-II Extrusion Blow Molding Machine is specially developed to cater to the growing demand for high-standard wide-mouth HDPE bottles and jars in various industries. Combining cutting-edge technology, stable performance, and user-centric design, this machine stands out as a reliable choice for manufacturers seeking to produce durable, leak-proof, and aesthetically pleasing HDPE containers, suitable for food, pharmaceuticals, cosmetics, and chemical packaging applications. It perfectly balances production efficiency and product precision, helping businesses reduce costs, improve competitiveness, and meet the diverse needs of modern packaging markets.

Equipped with a high-efficiency 70mm extruder, the DSB70-II ensures thorough melting and uniform plasticization of HDPE materials, which is essential for maintaining the structural integrity and barrier properties of wide-mouth containers. The extruder adopts a frequency conversion speed control system, allowing operators to adjust the extrusion speed freely according to different container specifications and HDPE material grades, effectively avoiding material waste and ensuring consistent product quality. Its robust structure and high-quality screw design enhance wear resistance and extend the machine’s service life, reducing maintenance costs for long-term operation.

One of the key advantages of the DSB70-II is its advanced parison control technology, which guarantees even wall thickness distribution for every wide-mouth HDPE bottle and jar. This not only improves the container’s load-bearing capacity and leak-proof performance but also reduces material consumption, optimizing production costs. The machine’s clamping unit boasts a strong clamping force of 120kN, ensuring stable clamping during the blow molding process and accommodating a wide range of mold sizes. With quick mold change capability, it can switch between different container models in a short time, supporting flexible production and adapting to small-batch customization and large-scale mass production needs.

The DSB70-II features an intelligent control system with a 7-inch touchscreen HMI, making operation simple and intuitive. All key production parameters, such as extrusion temperature, blow pressure, cooling time, and cycle speed, can be easily set and adjusted on the touchscreen. The system supports storing multiple production recipes, enabling quick parameter recall when switching between different products, greatly improving production efficiency. Additionally, built-in fault alarm and diagnosis functions help operators identify and resolve issues promptly, minimizing production downtime and ensuring continuous and stable operation.

Safety and energy conservation are also core considerations in the design of the DSB70-II. The machine is equipped with a full set of safety protection devices, including a safety guard with interlock functions, ensuring the safety of operators during operation. Its optimized heating system and energy-saving motor reduce energy consumption significantly compared to traditional blow molding machines, aligning with global environmental protection and energy conservation trends. The dual-circuit cooling system ensures efficient cooling of the extruder and mold, preventing material sticking and ensuring smooth demolding, further improving product quality and production efficiency.
