Specifications and maintenance of the membrane casting machine

Some specifications of the membrane casting device are as follows.

• Product size

  The length, width, and height of the membrane casting machine are respectively 1,215 millimeters, 900 millimeters, and 1,800 millimeters. The product size may vary depending on the model of the machine.

• Electrical parameters

  The voltage of the membrane casting machine reaches 380V, and the frequency is about 60Hz. The electrical parameters provide enough power and stability to ensure the normal operation of the machine.

• Production capacity

  According to the flow rate of the liquid, the production capacity of the membrane casting machine reaches 2000-5000L/h, which can meet the large-scale production demand. The machine can process such a large volume in a month.

Generally, the support of the membrane casting machine is aluminum alloy or stainless steel, which is strong and stable enough to carry heavy loads without causing any deformation. Aluminum profile extrusion casting has a wide application in the modern architecture and construction industry, mainly for either aesthetic purposes or to provide structural support.

The operation of the membrane casting machine requires a certain environmental condition. For example, the temperature should be maintained between 20 and 25 degrees Celsius. Meanwhile, the atmospheric pressure should be between 95 and 105 kPa. It can ensure the machine's optimal performance and stability by meeting these requirements.

To prolong the lifetime of the membrane casting device, it is vital to clean and maintain it. First, use a soft brush or sponge to clean the surface of the casting net with warm water and a mild detergent to remove dirt and dust from it. Then, rinse and dry the casting net thoroughly to avoid residual moisture. Besides, lubricating components, such as bearings or gears, periodically is also vital for ensuring smooth operation. Lubricants with high temperature resistance and good fluidity are usually used. Moreover, regularly calibrating and adjusting the casting machine according to the manufacturer's guidelines can ensure that its performance is optimal. It is also important to keep the machine dry and ventilated, which can help prevent moisture and rust damage to internal parts. Finally, pay attention to the operating temperature and pressure of the casting machine, which should be adjusted and controlled within the specified range to avoid damage caused by overloading for a long time.
