Production process of blown film machine: tips sharing and troubleshooting guide

Mastering key skills and strategies in the production process of blown film machines is crucial for improving production efficiency and product quality. Firstly, the selection and proportioning of raw materials are the foundation, and it is necessary to ensure the purity and suitability of the melt index of the raw materials to prevent impurities from entering the production process and the decrease in membrane performance.

In terms of skill sharing, precise grasp of preheating and temperature control is the key to ensuring the uniformity and strength of the film material. By finely adjusting the power and distribution of heating elements, as well as utilizing advanced temperature control systems, a smooth transition of film material from melting to blow molding can be achieved, avoiding uneven film thickness and fracture caused by temperature fluctuations.

In addition, the stable control of membrane bubbles is also an important aspect that cannot be ignored. By adjusting the blowing pressure, traction speed, and foam cooling rate, the stable formation and efficient traction of the foam can be ensured, thereby greatly improving production continuity and the flatness of the membrane material.

In the troubleshooting guide, we emphasize the importance of daily maintenance of equipment. Regularly inspecting the transmission components, heating elements, and control system of the blown film machine, promptly identifying and addressing potential wear and failures, can effectively prevent production interruptions and film quality issues.

At the same time, we provide a detailed troubleshooting process and solutions for common problems such as uneven film thickness, breakage, and bubbles, including adjusting process parameters, optimizing raw material ratios, and strengthening equipment cleaning to ensure the smooth and efficient production process of the blown film machine.
