Advantages of plastic granule gravimetric auto dosing machine:
Plastic granule gravimetric auto dosing machine is a highly efficient and advanced technology that is designed to save raw materials. This state-of-the-art machine has been developed to help reduce the waste of plastic granules that often results in high costs. By utilizing the latest technology, the machine can help to save between 1% to 5% of raw materials.
One of the significant advantages of this machine is that it uses minimum wall thickness control and concentricity adjustment to reduce the instability in the inner wall thickness caused by fluctuation. This helps to ensure that the plastic granules are treated in the most optimal way possible, reducing the risk of imperfections and minimizing the amount of raw materials required.
The plastic granule gravimetric auto dosing machine is also highly accurate, which eliminates the need for manual adjustments. This not only can save time but also ensures that the process is consistent and efficient.
Moreover, the machine is designed to be user-friendly, so that operators can easily manage and monitor the process. With its advanced automation technology, the plastic granule gravimetric auto dosing machine can deliver high-quality results with minimal human intervention.
Material usage saving principle
By minimum wall thickness control and concentricity adjustment, the system can reduce the instability of inner wall thickness caused by fluctuation, to saving raw material.
Material usage saving calculation formula= π [ (ID2/)2 –(ID1/2)2] * Density * Length
